      Abstract: Farmers rearing indigenous chickens in the villages or peri-urban settlements often have problems of accurately estimating body weight of their chicken. Therefore, the study was conducted to determine the best-fitted regression model for estimating body weight of Nigerian indigenous chickens using different linear body measurement. Data on body weight and body measurements recorded on 137 Nigeria indigenous chickens consisting of 57cocks and 80 hens were used for the study. Parameters measured were Body weight (BW), Body length (BL), Wing length (WL), Wing span (WS), Drum stick (DS) Shank length (SL), Body length (BL), Breast girth (BG) and Keel length (KL). Body weight was regressed on body measurements by forward, backward, stepwise and full model regression analysis, to determine the combination of body dimension for each sex that explains variation in the dependent variable for male and female chickens at 20th week of age. The outcome of the study showed that BW= -2223.73 +33.67SL +11.62DS +17.83BG +56.87BL +79.13KL and BW= -1608.61 +13.21WL +20.51BG +69.57BL are the best fitted regression model for predicting body weights of Nigerian indigenous cock and hen, respectively at 20 weeks of age.

  • Comparative assessment of brain and circulating oxidative stress
           biomarkers in weaned New Zealand White rabbits supplemented with microalga
           Chlorella vulgaris biomass

      Abstract: The brain is central to human and animal well-being but it requires a high amount of oxygen for its normal functioning and this makes it an organ highly vulnerable to oxidative stress damage. Therefore, for the promotion of normal physiological and cellular functions of the brain, antioxidant intake is very critical. This study investigated the antioxidant enzymatic activities in the brain by measuring activities of superoxide dismutase (SOD), catalase (CAT), and reduced glutathione (GSH) in connection with the circulating oxidative stress biomarkers of the serum and liver of New Zealand White rabbits supplemented with microalga Chlorella vulgaris biomass in addition to regular basal diets. The study involved a random distribution of 40 rabbits of eight weeks old into five experimental group using completely randomized design. The rabbits were observed for a period of 120 when they are being supplemented after which their blood, brain, and liver were collected for analyses. The results show that the total antioxidant capacity was higher in the brain of the supplemented rabbits (P<0.05). Although, there was no significant difference in the brain malondialdehyde concentrations, there were higher activities of antioxidant enzymes in the brain of the supplemented rabbits (P< 0.05). There was a lower concentration of the circulating malondialdehyde (MDA) in the serum and liver of the supplemented rabbits. The study concluded that Chlorella vulgaris intake led to reduced circulating malondialdehyde and increased activities of the brain antioxidant enzymes in the rabbits. The study indicated that the microalga Chlorella vulgaris contains antioxidant compounds that can cross the blood-brain barrier, which could be a very important therapeutic agent against oxidative stress-induced brain complications in animals and humans.

      Pages: 19 - 27
      Abstract: The study was conducted to assess the semen quality characteristics of broiler breeder cocks under selection at young (22 - 29weeks) and adult (30 - 40weeks) ages in a pedigreed population. Data were collected on a weekly interval for body weight and semen quality characteristics (sperm volume, semen colour, sperm motility, semen pH, sperm concentration and live cell) and semen morphological defects (detached head, coiled tail, bent tail and full head) and were analyzed using the SAS statistical package. Sequel to semen collection, body weights of each cock were taken and recorded. Results obtained for body weight at the two age groups showed a significant (p <0.05) difference with the adult cocks been heavier as the age advanced. The semen quality showed a highly significantly (p<0.01) difference at all ages with the exception of live cells for the adult breeder cocks’ group where the trait showed no significant (p>0.05) difference across weeks. The semen morphological defect of young breeder cocks showed a progressive significant (p<0.01) increase with the highest defect of 21.20% at 27 weeks, while for the adult cocks, the highest defect was recorded at 30 weeks with 23% defect. It can therefore be recommended that for optimum reproductive performance of the broiler breeder cocks under selection, cocks should be introduced into hen pens or used for artificial insemination at about 26weeks of age under favourable conditions that promote optimum quality semen, which can enhance fertility and hatchability for pedigree hatching

      Abstract: This experiment was conducted to examine the fertilising ability of layer breeder cock spermatozoa extended with normal saline fortified with varying levels of carrot juice using 10 breeder Bovan Nera cocks. Semen was collected from the cocks, pooled and divided into six portions (treatments). Treatment 1(TUS) was undiluted semen which served as a control, while Treatments 2 (TNS) and 3 (TMRS) were diluted at 1:1 with normal saline and modified ringer solution, respectively. Treatments 4 (T25%CJ), 5 (T50%CJ), and 6 (T75%CJ) were diluted at 1:1 with normal saline fortified with 25%, 50% and 75% carrot juice, respectively, and stored at room temperature (27.0±0.2). Sperm motility and liveability reduced (p<0.05) as time of storage increased. In vivo study was carried out with 70 hens randomly allocated and inseminated with each of the 5 treatments. The fertility among the treatments was 75% (TNS), 100% (T2), 60% (T3), and 83.33% (T4), while optimum of 60% at day 3 and 50% at day 7 were obtained for T3 and T5 respectively. Duration of fertile period was prolonged by carrot juice for T50%CJ and T75%CJ respectively by 2 and 3 days relative to TNS and 5-6 days for TMRS. Embryonic mortality and hatchability were similar among the treatments

      Abstract: The study was conducted to determine the effect of dietary inclusion of vitamin E as anti-oxidant on the semen characteristics of local cocks. Avian spermatozoa are subject to oxidative stress, causing male infertility because of its high polyunsaturated fatty acids content. Therefore, it was justified to research and report on the use of vitamin E as an antioxidant on the semen characteristics of local cocks. A total of 50 mature local cocks of uniform sizes (weighing about 1.52-1.53kg) were used for the study. Their exact ages were not known due to the lack of adequate record keeping by the traditional household keepers. The birds were divided into two treatment groups with 25 birds per treatment. Data generated were analyzed using independent group sample t-test. Each treatment had five replicates with 5 birds per replicate. Feed fed to T1 birds contained 1000 IU vitamin E kg-1 feed, while T2 (control) feed had no vitamin E. From the results obtained, sperm progressive motility, live: dead, normal and abnormal sperm cell morphologies were found to be highly significant (p<0.01), while semen volume and sperm concentration were significant (p<0.05). T1 birds that fed diet containing vitamin E had the highest percentage values for semen volume, sperm progressive motility, live sperm cells, normal sperm cells and sperm cell concentration compared to control birds (T2). Percentage values for dead and abnormal sperm cells were highest in control (T2). In conclusion, the use of vitamin E as anti-oxidant to improve semen qualities was recommended because of higher values of sperm progressive motility, semen volume, live sperm cells, normal sperm cells and sperm cell concentration recorded in T1.

      Abstract: This study investigated supplementation effect of unprocessed black seed on the growth, testicular and epididymis characteristics of rabbit bucks. Forty (40) weaned male rabbits were weight-balanced and assigned to four dietary treatments with 10 animals each. The rabbits were fed with diet containing 16% crude protein and 2300 Kcal/kg metabolizable energy. The four experimental treatments were supplemented with black seed at levels of 0, 0.5, 1.0 and 1.5% denoted as T1, T2, T3 and T4, respectively. Data were obtained for weight gain and feed intake. Feed conversion ratio (FCR) was calculated accordingly. Other parameters evaluated include testicular and epididymal characteristics. Data collected were subjected to one-way analysis of variance. A significant (p<0.05) increase was observed in the growth indices as black seed supplementation increased up to 1.0%. Rabbits fed T3 recorded significantly (P<0.05) higher average daily gain, average daily feed intake and the best FCR. Significant (p<0.05) increase was observed in all the testicular and epididymal variables as black seed supplementation increased up to 1.0%. In conclusion, supplementation of black seed improved the growth performance, testicular and epididymal characteristics of rabbit bucks. Rabbits fed 1.0% black seed supplementation elicited the best performance in terms of the growth, testicular and epididymal characteristics.

      Abstract: A study was carried out to search for alternative energy sources for maize in poultry diet. A 9-week experiment was conducted to ascertain the effect of diets containing feeding varying levels of Irish potato peel meal (IPPM) used to replace maize with enzyme supplementation on the carcass quality, haematological and blood biochemical profile of broiler chickens. Two hundred and forty (240) Anak-2000 broiler chicks aged 6 days were randomly assigned to 12 floor pens containing 20 birds each. Four diets were formulated based on 23 and 20% crude protein in the starter and finisher phases respectively, to contain 0, 5, 10 and 15% IPPM supplemented with enzyme to serve as replacement for maize. Each of the diets was fed to 3 pens of 20 birds in a completely randomized design. Data were collected on carcass quality and blood samples at the end of the experiment. There were no adverse effects of the test material on the carcass quality, haematological and blood biochemical profile of broiler chickens.

      Pages: 67 - 74
      Abstract: This study undertook a prospective serological and bacteriological survey for Leptospira infection inferred to be endemic by previous sketchy research in most regions of Nigeria. An enzyme conjugate system and culture isolation globally used to screen for Leptospira was used to screen blood and urine samples collected in canine population in studied region. Major objective is to determine potential spatial occurrence of the infection so that quantitative and qualitative risks will be demonstrated for informed public health safety. An overall serological and bacteriological prevalence of 16.4% and 11.75 respectively was recorded. Out of the nine districts studied, only 3 (33.3%) were negative for Leptospira in the State, 6 (66.7%) of the nine districts were positive for isolates constituting a widespread distribution of subsets of canine population closely in contact with humans serving as potential maintenance and dispersal source of leptospires. Two districts presented a statistically significant (P<0.05) association in isolation of Leptospira and the region of study essentially due to demographically and socio-economically related variables determining outcomes. This study demonstrates empirical data of circulating leptospires in dogs with widespread distribution. There is therefore a qualitative and quantitative risk for zoonotic spread given an ever-existing canine human bond, this also establishes risks for livestock population given evidence of cross species infection with canine adapted leptospiral serovars

      Authors: A.B. Ahmed, S.E. Thomas, K.S. Christopher
      Pages: 75 - 89
      Abstract: It has been proven that foot and mouth disease virus (FMDV) is a highly contagious, severe and economically devastating viral disease worldwide, which affects animals with cloven hoof such as cattle, deer, pigs, sheep and goats. Thus, this study aimed at investigating the molecular genetic variation of FMD virus of cattle. A total of twenty FMD virus amino acid sequences of cattle were retrieved from the GenBank. Various serotypes of FMD virus were identified. The obtained phylogeny based on amino acid sequences of the FMD virus revealed differential clustering among the sequences. The predicted 3D FMD protein structures of cattle aligned well with the templates. The present information on FMDV biodiversity and evolution could be exploited in tracing FMDV sources and transmission events, as well as to ensure vaccine coverage of corresponding field of FMDV extractions mostly in a developing country such as Nigeria.

      Authors: M.B. Bislava, J.U. Igwebuike, S. Buba, A.I. Bukar
      Pages: 90 - 99
      Abstract: Guinea pig (Cavia porcellus) is a promising micro-livestock which though is indigenous to South America, is also well adapted to Nigerian ecosystem. The meat is nutritious, with a protein content of 21%, which is higher than that of poultry, pork, mutton or beef. About 65% of its meat is edible with a low fat content and low cholesterol, making it the ideal meat in an increasingly health-conscious population. The animal has a short gestation period of (58-72 days), low cost of production, matures early, easy to manage and requires relatively little capital to set up. Nigerians are among the least consumers of animal protein in Africa, consuming less than World Health Organization’s (WHO) recommended 67 g per day. The commonly conventional livestock species reared cannot meet the protein deficiency because their multiplication rate is not commensurate with the rapid increase in human population. In Nigeria, if the challenges of availability of quality concentrate feeds, problem of numerous pests and diseases, problem of excessive heat and problem of obtaining fast growing species of pups can be overcome, then guinea pigs farming has the potential of bridging the present protein deficiency gap in Nigeria

      Abstract: The current study was undertaken between September, 2020 and February, 2021 to determine the prevalence of fish parasites infesting catfish Clarias gariepinus and the associated risk factors in Zobe reservoir Dutsinma, Katsina State, Nigeria. A total number of 90 fish samples were collected and examined from Zobe reservoir. Out of 90 fish samples from Zobe, 47 were male and 43 were female. Fish parasites recovered and their prevalence among Clarias gariepinus obtained from Zobe reservoir: Digenean genera; Astiotrema sp. 5 (5.82%), Miracidium larvae 3 (3.48%), Metacercariae sp. 8 (9.31%), Cestode genera; Monobothrium sp. 21 (24.42%), Pleurocercoid or Coradium sp. 5 (5.82%), Nematode genera; Ascaris eggs 20 (23.26%), Capilaria sp. 14 (16.28%), Camallanus sp. 8 (9.31%), Ascaridods or Anisakis sp. 2 (2.33%). The prevalence of parasites recovered from the fish species in this study was high. In conclusion, Clarias gariepinus from Zobe reservoir were infected by several parasites that are of economic importance. The findings suggest that the observed parasitic infections may adversely affect C. gariepinus and if not well managed, could also infect human beings who consume the fish. It is therefore recommended that communities along the reservoir should desist from activities likely to increase parasite load, also, the gastro-intestinal tract of harvested fishes from the study area should be discarded rather than consumed to prevent zoonotic diseases.

      Abstract: Nigeria is the highest fish consumer and offers the largest market for fish and fisheries products in Africa, fish as food is the main source of animal protein to this teemed population. Although domestic fish production is on increase despite this, the country still experiences short fall due to rapid growing human population. This study therefore estimates the technical efficiency and factors responsible for inefficiency of catfish production in freshwater culture systems using data envelopment analysis (DEA). The result shows that estimated inefficiency coefficients for age and household size (p<0.05); experience, farm size and extension service (p<0.1) were statistically significant. This agrees with the priori expectation that technical efficiency should increase with increase in these parameters. Furthermore, all inputs used by catfish farmers in production processes indicated slacks but at different degree. Fish feed, being the most important input in fish production, constitute more than half of production cost thus, farmers in the study area could operate on the production frontier by reducing their feed input levels by 7.33% and 8.25%, for concrete tanks and earthen ponds respectively. However, Research Institute and University should come up with a well-defined, nutritionally complete and affordable feed for catfish production and disseminate same to farmers. Also, subsidy programme should be introduced to reduce production costs, increase farmers’ income and provide enough animal protein to the teeming population at affordable price.

      Abstract: True metabolizable energy determination of raw and processed C. tora seed meal was undertaken. Fifty (50) arbor acre broiler chicks, reared to 10 weeks were used, out of which fifteen (15) birds were randomly selected for the trial. The birds were weighed, randomly divided into groups A (fed birds) with 12 birds and B (unfed birds) with three birds. Three birds each in group A were randomly assigned to raw and different processes C. tora seed meal viz toasted, boiled and soaked-and-boiled diets, replicated thrice, with one bird per replicate. The birds were placed in individual metabolism cages and fasted for 24 hours. Thereafter each birds in group A were force-fed 25g of raw and processed Cassia tora, returned to their cages and the time recorded, and trays were placed for collection of excreta, after 24 hours. Birds in the control (group B), were subjected to fasting for 48 hours, and their faeces were also collected. All feed and faecal samples were sundried, bulked, milled and analyzed for energy using the adiabatic oxygen bomb calorimetric method. The results showed significant (P<0.05) difference across the mean TME measured between the raw and processed seeds. It was also observed that boiled and soaked-and-boiled processing methods resulted in 92.07% and 91.50% efficiency of energy bioavailability of Cassia tora while toasting method recorded 89.10%. The mean TME values ranged between 2.08Kcal/g for birds force-fed the raw to 2.80 Kcal/g for birds force-fed the soaked-and-boiled seeds. The boiled and soaked-and-boiled seeds had the highest TME values, while the lowest TME value was recorded for raw Cassia tora seeds. In conclusion, processed Cassia tora seeds encouraged better true metabolizable energy than the raw, and are effective, resulting in up to 91% efficiency of energy bioavailability of Cassia tora seeds.

      Abstract: Teak is more considered as a major constituent in many of the traditional medicines. The proximate and phytochemical analysis of Tectona grandis leaf meal were carried out by adding it as an additives or supplements in the feed fed to broiler chickens. The fresh leaves were sliced and air-dried for 10 days and milled into fine particles. The prepared sample was kept in air tight polythene bags to prevent exposure to air, the leaves were subjected to proximate and phytochemical analysis. Data showed that the leaves had low moisture 4.57±0.40%, high carbohydrates 40.30±1.07%, protein, fibre, fat and ash of 13.28±0.28%, 28.29±0.52%, 2.17±0.28%, 11.4±0.40%, respectively. The leaf samples of Tectona grandis were screened quantitatively. Results revealed the presence of flavonoid, saponin, phenol, alkaloids and tannins. Saponin, phenol and tannin were present in large amount with 55.55±20.83mg/g, 44.87±4.41mg/g and 10.50±0.56mg/g, respectively which are responsible for its antioxidant and antimicrobial. It is completely clear from the proximate analysis that Tectona grandis leaf meal can be used as alternative medicine and animal growth promoters.

      Abstract: The phytochemical, proximate and mineral compositions of seed powder and aqueous extract of Picralima nitida as a medicinal plant was investigated. Picralima nitida pods were sourced from Ago Owu Farm Settlement, Ikoyi, Osun State, Nigeria, broken to remove the seeds which were processed into powder form and subsequently extracted using aqueous solution. The percentage yield after extraction was 27.25%. Proximate composition (%) of Picralima nitida seed powder (PnSP) and aqueous Picralima nitida Seed Extract (PnSE) were: crude protein (13.92±5.23% and 16.44±4.13%), ether extract (7.13±1.42% and 2.08±0.15%), crude fibre (7.15±4.26% and 15.00±0.18%), ash (6.82±3.74% and 4.97±0.06%), nitrogen free extract (58.09±5.27% and 51.70±2.82%) respectively. The seed powder and extract of P. nitida showed good contents of macro and micro elements. The seed powder had higher contents of most mineral elements except manganese (4.25±0.45 mg/kg), molybdenum (0.03±0.00 mg/kg) and sulphur (0.04±0.00 mg/kg) which were higher in PnSE. Saponin (267.11±4.37 mg/100g), tannin (6.84±0.41 mg/100g), flavonoid (5.47±0.84 mg/100g), alkaloid (295.19±2.80 mg/100g) and oxalate (124.35±3.78 mg/100g) were highest in PnSE compared to the PnSP. It could be concluded that Picralima nitida has adequate nutrients, minerals and bioactive secondary metabolites that could be exploited for use as a phyto-additive in poultry diets.

      Abstract: This study investigated the growth performance characteristics of broiler finisher birds fed three different leaf meals at 5% inclusion level in a 28-day trial. The leaf meals obtained from three forage plants namely, Moringa oleifera, Pueraria phaseoloides, and Pennisetum purpuruem were added as protein substitutes and partial supplements for soya bean in the diet and birds were fed ad libitum. A total of one hundred and twenty (120) 4 week old broiler birds were allotted to four treatment groups of 10 birds each with three replications in a completely randomized design (CRD). The results showed significant differences (P<0.05) in the feed intake, final weight gain and average weight gain but no significant differences were observed in feed conversion ratio. The control diet had the highest average weight gain of 1706.67g and Pueraria phaseoloides having the least value of 1208.33g. Pennisetum purpuruem exhibited the highest weight gains amongst the leaf meals under study. The shank and skin colouration was more apparent in the birds fed Moringa oleifera leaf meals showing that it may contain higher levels of xantophylls and other beneficial antioxidants. It could be concluded that Pennisetum purpuruem leaf meal in broiler finisher diet provided better results for optimum weight gain and productivity and is therefore recommended above Moringa and Pueraria.

      Abstract: A 28-day feeding trial was conducted to investigate the growth response, hematology and serum biochemistry of finisher broiler chickens fed blended bovine blood plasma (BBP) and soyabean hull (SBH) mix. Four diets containing 0, 50, 75% and 100% mixture of bovine blood plasma and soya bean hull (BBP/SBH) coded T1, T2, T3 and T4 respectively were fed to 120 Anak broiler finisher birds. The birds were divided into 4 groups of 30 broilers per treatment replicated 3 times with 10 birds per replicate. The treatment diets were randomly assigned to the birds in a Completely Randomized Design (CRD). Performance data showed that the test ingredient significantly affected the daily feed intake, feed conversion ratio and daily weight gain of broiler birds. The results showed that hematological values like the Hemoglobin (Hb), Packed cell volume (PCV), Red blood cells (RBC) and white blood cells (WBC) decreased significantly (P<0.05) as the levels of BBP/SBH in the diets increases while the mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC) and clotting time increased proportionally. Serum biochemical parameters like Creatinine and Glucose increased as dietary BBP/SBH mixture increased in the treatment diets. Based on the above result, treatment 3(75%) mixture of BBP/SBH) is recommended to livestock farmers for optimum meat production and for profit maximization.

      Abstract: This experiment was conducted to boost animal protein consumption in the Nigerian populace using an unconventional feedstuff–pineapple wine sediment meal (PWSM) which is a waste product of the winery. In the study, PWSM was used to evaluate the growth performance of grower pigs using 32 large white x landrace strains of pigs with average initial weight of 32 ± 0.07kg. Four treatment diets coded T1, T2, T3 and T4 replicated 3 times were formulated to replace maize at 0%, 10%, 20% and 30% levels respectively and the study lasted for 35 days. The result of the experiment indicated that PWSM enhanced the palatability and feed intake of the growing pigs because of the proteolytic enzyme, bromelain which stimulated healthy metabolism. It was established from the result that PWSM could replace maize partially up to 10% dietary levels for optimum performance of grower pigs and that at higher levels of 20% despite positive impacts on the economy of production; growth rate and feed conversion are negatively affected. Hence, 10% inclusion level is recommended for optimum productivity and for maximization of profit in the industry

      Abstract: The carcass yield, organ weights and haematological indices of finished broiler chickens fed urea plus methionine supplemented and re- fermented sorghum beer residue (RSBR) were investigated after a 4-week finisher period. Three hundred (300) 28days broiler birds were randomly allocated to 15 pens (20 birds per pen) for the finishing period. They were fed diets containing RSBR at graded levels of 0, 25, 50, 75 and 100 %. At day 56th, three birds from each pen were selected for blood sampling and carcass analysis. The dressing percentage of birds on 50% RSBR diet was significantly higher (P < 0.05) compared to others. The breast weight percentage for birds on the control was observed to be highest significantly (P<0.05) while that for birds on 100% RSBR was lowest (P<0.05). The thigh percentage of birds on control and 50% RSBR diets were similar but significantly (P<0.05) higher than those of birds on other diets. Heart and gizzard percentages of birds on 100% RSBR diet were significantly higher (P < 0.05) than those on control and other diets. The packed cell volume and haemoglobin concentrations of birds fed on all RSBR supplemented diets were within normal ranges but were significantly higher (P < 0.05) than those of birds fed control diet. This study indicated that up to 75% RSBR can adequately support carcass yield, and organ weights without detrimental effect on finisher broiler chickens.

      Abstract: One hundred and fifty day old broiler chicks were used in 56 days feeding trial to determine the effect of four different types of natural sources of methionine on performance of broiler chicken. Five broiler starter and finisher diets were formulated such that Diet 1 was the control and contained the DL – methionine, while Diet 2, 3, 4 and 5 contained 2.5% Moringa oleifera seed (MOS), Boiled Jatropha seed (BJS), Hibiscus sabdariffa seed (HSS) and Cashew nut seed (CNS) respectively. The birds were randomly allotted to the five diets in a completely randomized design. Each treatment comprised of three replicates of ten (10) birds per replicates. Performance, blood and economic analysis were monitored. The result showed that final weight (217.33 – 249.33g), daily weight gain (6.30 – 7.63g) and feed conversion ratio (2.37 – 3.2) were not significantly (p>0.05) affected by the treatments, except average daily feed intake and mortality which were significantly (p<0.05) affected by the treatments. The result of blood profile showed that WBC (2.49 – 3.00 (x109/L)), RBC (2.06 – 2.52(x106/ml)), MCV (117.73 – 120.17(fl)) and PLT (19.67 – 22.33 (cells/l)) which fall within the normal range were not significantly (P>0.05) affected by the treatments, except Hb, PCV, MCH, MCHC which wsere significantly (P<0.05) affected by the treatments. All biochemical indices were not significantly (P> 0.05) affected by the treatment except cholesterol and globulin. Cost of feeding/kg and cost of feed consumed per bird was lowest in T1 (#131.00) and was highest in T5 (#218.00). Feed cost/kg gain was highest in T5 (#496.75) but lowest in T3 (#221.24), while total weight gain/kg was highest in T4 (1.77kg). Cost of feeding/kg and cost of feed consumed per bird was lowest in T1 (#131.00) and was highest in T5 (#218.00). T4 (#156.00) was lowest since it contains less anti nutritional factors than the counterpart T3 (#156.00). Feed cost/kg gain was highest in T5 (#496.75) but lowest in T3 (#221.24), while total weight gain/kg was highest in T4 (1.77kg). Based on this study, replacement of DL – methionine with 2.5% HSS could result in higher profit margin for poultry farmers because most of the time, consumers prefer heavy birds with high cost than light bird with lower cost.

      Abstract: This study was conducted to determine the effects of supplementing broiler feeds with different levels of Coconut Shell Charcoal (CSC) on the serum biochemistry, haematological parameters and gut microbial count (Total coliform count; TCC and Total Bacterial Count; TBC). The experiment was conducted with a total of 90 unsexed Day-Old broiler chicks of Ross 308 strains and it lasted for fifty-six days. The chicks were randomly allotted to six different treatments (T1, T2, T3, T4, T5 and T6, containing 0%, 2%, 4%, 6%, 8% and 0% CSC respectively) with each having 15 birds and each treatment further divided into three replicates of five (5) birds in a Completely Randomized Design (CRD). While the T1 and T6 did not have coconut shell charcoal, the treatment 6 was administered antibiotics when necessary (this would serve as a marker in the measure of blood parameters and microbial load). The result from the analysis of these data showed that the supplementation of the feed with charcoal, significantly affected (P<0.05) only a few of the serum (Aspartate Aminotransferase, Alanine Aminotransferase) and haematological parameters (Platelets). However, there was a significant difference (P<0.05) in the TCC and TBC but the counts were higher in the treatments with charcoal than the control. Therefore, irrespective of the fact that the use of coconut shell charcoal at these levels was not detrimental to the birds with respect to haematology and serum biochemical parameters, its use at these levels (2%, 4%, 6%, and 8%) is not recommended since these levels were suspected to increase the gut bacterial and coliform count of the broiler birds. The total white blood cell was highest in the treatment six which entails that administering antibiotics was a better way of boosting immunity than the coconut shell charcoal.

      Abstract: This study was carried out to investigate the growth performance, nutrient digestibility and carcass characteristics of Japanese quails fed graded levels of garlic meal The birds were randomly allocated to four dietary treatments of one hundred twenty four (124) birds each, and were replicated three times in a completely randomized design with thirty one (31) birds per replicate. They were fed four experimental diets containing 0, 250g, 500g and 750g garlic meal. Feed and water were provided ad libitum. Data obtained were subjected to analysis of variance using Statistical Analysis System and significant differences between treatment means were separated using Duncan Multiple Range Test. There were significant differences (p<0.05) in final weight, weight gain, average daily weight gain, total feed intake, feed conversion ratio, feedcost/kg gain and mortality across the treatment groups. It was observed that quails fed dietary level of garlic meal at 750g had the best results in terms of all the parameters for performance and nutrient digestibility, except for crude protein that compared favourably at 500g and 750g inclusion. However, it was observed that Japanese quails fed garlic meal at 750g had the best live weight and no significant difference (p<0.05) was observed for dressed weight and dressing percentage. For optimal productivity 750g inclusion of garlic meal is therefore recommended.

      Abstract: Nutritive value of concentrate feeds fed to rabbits by smallholder farmers in Greater Port Harcourt City (GPHC) were assessed in two of its eight Local Governments. Thirty-five rabbit farmers; 20 and 15 from Obio-Akpor and Ikwerre, respectively, were sampled, using snowballing method. Overall, five samples: three commercial poultry (D1, D2, D3), one commercial rabbit-specific (D4), and one on-farm mixed feed (D5), were collected and analyzed for proximate, fiber fractions, minerals and anti-nutritional factors contents. Descriptive statistics, one-way analysis of variance at 0.1% level of significance and Duncan Multiple Range Test in SPSS data analysis software were used to analyze data. Results indicate percent dry matter, crude protein, ether extract, crude fiber, ash, nitrogen free extract, organic matter and metabolizable energy (kcal/kg) ranged from 91.90–90.97, 18.03–16.64, 4.05–3.55, 9.67–5.55, 7.13–5.97, 58.87–54.20, 85.94–84.24, 3014.80–2813.30, respectively. Minerals (mg/kg) ranged from 0.402–0.385 (sodium), 0.626–0.612 (calcium), 0.962–0.947 (potassium), 0.539–0.521 (phosphorus), 0.346–0.321 (magnesium), 48.15–46.75 (iron), 5.53–5.37 (copper), 61.87–60.52 (zinc), 4.86–4.48 (manganese) and 0.089–0.076 (selenium). Percent neutral detergent fiber, acid detergent fiber, acid detergent lignin, hemicellulose and cellulose ranged from 44.87–31.27, 33.05–19.66, 7.13–3.24, 13.0–7.46, 25.92–16.16, respectively. Trypsin inhibitors (mg/g) and percent tannins, phytate, oxalate, saponins and alkaloid ranged from 2.58–2.19, 0.0046–0.0030, 0.409–0.386, 0.292–0.269, 0.402–0.367 and 0.596–0.543, respectively. All feeds may supply enough proximate components to rabbits, except crude fiber. Actively reproducing rabbits fed those feeds may not cover their needs for calcium, phosphorus, iron, zinc, manganese, lysine, potassium, magnesium, copper, acid detergent fiber, neutral detergent fiber, hemicellulose and cellulose. Only acid detergent lignin contents of D5 and D4 were sufficient for rabbit needs. D5 followed by D4 may be fed sole to rabbits, if fortified, especially, with dietary fiber from sources like forages. There is need in Nigeria, needs to produce more commercial rabbit-specific concentrate feeds, that meet rabbit nutrient requirements.

      Abstract: The frequent changes in the prices of conventional protein feed sources have prompted the search for alternative locally feed resources with minimal competition between man and livestock without any deleterious effect on health of the animal this necessitated a 56-day feeding trial to determine the effect of feeding four differently processed Roselle seed meals as partial replacement for soybean meal on haematological and serum biochemical indices of broiler chickens. One hundred and fifty (150) one -day old Arbor acre (+AA) Broiler chicks were randomly allotted to five (5) dietary treatments comprising three replicates and ten chicks per replicate. The experimental diets were formulated with supplementation of differently processed Roselle seed Meal [DPRSM] in the diets of broilers at 15% inclusion levels regardless of the processing methods. The treatments were designated as T1, T2 T3, T4 & T5 as control diet (no Roselle seed meal), fermented Roselle seed meal (FRSM), boiled Roselle seed meal (BRSM), lye Roselle seed meal (LRSM) and enzyme Roselle seed meal i.e. (enzyme + raw Roselle seed) (ERSM) respectively. Data obtained were subjected to Analysis of Variance [ANOVA] using (22) and significant means were separated using Duncan’s Multiple Range Test of same statistical package at 5% level of probability. The result revealed significant (P<0.05) differences in the heamatological parameters measured except for packed cell volume (PCV), hemoglobin (Hb), red blood cells (RBC) and mean Corpuscular Volume (MCV). Birds fed fermented, boiled, lye and enzyme Roselle seed meal had the highest (P<0.05) mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), white blood cells, neutrophils and eosinophil. Furthermore, the serum biochemical indices showed no difference (P>0.05) in all measured parameters except for alanine transaminase (ALT), aspartate serum transaminase (AST) & alkaline phosphatase (ALP). Birds fed enzyme Roselle seed meal had the highest ALT while the least value were observed in T1, T2, T3 and T4 respectively. In conclusion, the four differently processed Roselle seed meal could be used to partially substitute soybean meal in broilers diet without posing any treat to health of the birds.

      Abstract: The successive government is often faced with the challenge of making policies that will ameliorate the farmers' production constraints and improve the economy. The study tries to assess needs and intervention techniques among farmers in the Egbeda LGA of Oyo State, Nigeria. A three-stage sampling technique was used to purposively select about 225 respondents. Parameters measured were household characteristics, and assessed needs using focus group discussion (FGD) and structured questionnaire. Data were analyzed descriptively and the need assessed using the pair-wise ranking and simple matrix. The five prioritized challenges listed in FDG among crop-livestock farmers were poor pricing of agricultural produce (Pb1), lack of capital (Pb2), the infestation of Cacao pests and diseases (Pb3), lack of processing (Pb4) and lack of farm Input (Pb5). The pairwise comparison of the percentage of Pb1 versus (vs.) Pb2 was 80/20%, Pb1 vs. Pb3 was 90/10%, Pb1 vs. Pb4 was 70/30%, Pb1 vs. Pb5 was 80/20%, Pb2 vs. Pb3 was 70/30%, Pb2 vs Pb4 was 30/70%, Pb2 vs. Pb5 was 10/90%, Pb3 vs. Pb4 was 20/80%, Pb3 vs. Pb5 was 10/90%, vs. Pb4 vs Pb5 was 70/30% respectively. The poor pricing was ranked highest as farmers' need assessed for possible intervention in Egbeda LGA.
