- Evaluation of the probiotic potential of NCIMB 11181 as a possible
candidate in animal nutrition
Abstract: Enterococcus faecium (NCIMB 11181) was evaluated for survivability, safety, and capacity as probiotics utilization. Gram-positive, catalase-negative test, antibiotics susceptibility, hemolysis activity, pH and bile salts resistance were screened using selective microbiological media. The strain was phenotypically assessed for its principal probiotic properties. The capacity of fermentation based on biochemical tests was evaluated by API 20STREP and interpretation by apiwebTM Biomerieux (France) software (99.2% very good identification). After incubation at 37°C for 22-24 h in aerobic conditions, E. faecium involves 13.96 Log10 with an optical density (OD 600 nm) from 0.2 in the first 2 hours of growth to 0.9 value. The safety assessment on TSA agar showed that the strain revealed α-hemolysis. Resistance to 16 clinically relevant antibiotics, presented for our strain a range from intermediate (81.25%) to susceptible (6.25%), followed by resistance to erythromycin and colistin sulfate. The strain exhibited tolerance to acidic conditions and simulated gastric environment. Therefore, E. faecium NCIMB 11181 can be considered a safe strain without creating a risk to animal health status. It may be used as a probiotic preparation product for application in animal nutrition.

- The effects of leaf powder in laying hens’ diets on egg physical
parameters and yolk color
Abstract: The experiment studied the effects of different levels of Rumex patientia spp. leaf powder inclusion in laying hens’ diets on their physical parameters and yolk color intensity. The study was conducted on 168 Hy-line laying hens (30 weeks aged), assigned in 3 treatment groups (C, E1 and E2) and housed in an experimental hall equipped with Big Dutchman cages, placed on 3 tiers with digestibility cages (3 treatments × 28 replicates × 2 birds per cage). Feed and water were administrated ad-libitum. During the entire 5 weeks experimental period (one week of accommodation), performance parameters were recorded: average daily feed intake(g/day/hen), feed conversion rate (g feed/g egg), laying rate intensity (%) and average egg weight (g). Eggs yolk color is generated by carotenoids as a nutritional response, which depends on their amount, type, and ratio. One of the most important aspects in how consumers rate the quality of food is color. The experimental results demonstrated that an inclusion rate of 1.5% and 3% Rumex patientia species leaves powder improved the yolk color intensity without negative effects on production performances and egg quality parameters.

- Potential implications of natural antioxidants from plant to improve
nutritional quality, oxidative stability and lipid degradation of egg
yolk: A review
Abstract: Food occupies a principal role in human life, having a major impact on health status and representing diverse characteristics that ensure valuable nutrient intake. Ensuring human nutrition has become one of the essential problems facing mankind, and quantity, quality and proper use of food have a major effect on the human body. Many raw materials and food products spoil easily, considerably shortening their shelf life. Extending the shelf-life of food is required to remove seasonal consumption, enlarge availability to the consumer and decrease losses in perishable food products, resorting to some procedures to preserve their properties. If natural antioxidants are used as alternatives for synthetic antioxidants, customer claims for food without damaging residual substances can be satisfied, and the poultry industry would benefit considerably. The principal objective of this review was to describe and under light the current situation regarding the role and importance of the use of antioxidant compounds obtained from natural sources in order to improve the nutritional qualities of eggs following their inclusion in the feed of laying hens. Data from bibliographic sources are analyzed and presented. The characteristics of a number of 9 plants with antioxidant potential are described with an emphasis on their characteristics, utilization, and possible effects on egg quality, performance, and health.

- Development of dual-purpose cross for meat and egg production II. Meat
quality of the crossbred chickens and the parent lines
Abstract: The study aimed to examine the meat quality of chickens from a dual-purpose cross and its parent lines. The trial was conducted in the experimental poultry farm of the Institute of Animal Science-Kostinbrod, Bulgaria. The dual-purpose chickens were obtained by crossing female layers (Line L) and dual-purpose cocks (BB, based on Bresse Gauloise). At the age of 9 weeks the male chickens from the parent lines and the dual-purpose cross were slaughtered. Six chickens of each genotype were subjected to breast and thigh meat quality analysis. The crossbred chickens tended to have lower pH in breast but the values of this parameter were higher in their thighs. The BB line showed the poorest water-holding capacity (WHC) in both breast and thigh meat cuts. This line and the crossbreed showed lighter meat compared to the L line. Except the ash content of the breast and thigh meat that was higher in the BB line, the proximate composition did not differ between the examined lines and their cross. The L and dual-purpose chickens tended to have higher intramuscular fat (IMF) but lower protein in thigh meat than the BB line. The correlation analysis revealed clear relationships between the meat quality traits and the proximate composition, however they differed for the breast and thigh meat.

- Comparative analysis of bioactive compounds and antioxidant capacity of
selected plants as phytogenic feed additives for poultry nutrition
Abstract: The paper investigated the phytochemical content and antioxidant activity of poplar buds (Populus nigra L.), turmeric (Curcuma longa) and ginger (Zingiber officinale) extracts. Proximate composition, total polyphenols, ß-carotene, vitamin E, minerals and antioxidant capacity were tested for all selected plants. The proximate analysis of selected plants showed that poplar buds had a higher content of crude protein, fat and fiber than turmeric and ginger. The extract of poplar buds had a significantly higher content of total polyphenols (87.20 mg of gallic acid/g) and vitamin E (210.53 μg/g) than in the extract of turmeric and ginger. The polyphenol content was found to be in the order: poplar buds>turmeric> ginger. The beta carotene content was significantly higher in poplar buds (2.99 μg/g) than in turmeric (1.67 μg/g). Regarding mineral content, turmeric showed the highest content in iron and copper; ginger showed the highest content in manganese and poplar buds had the highest content in zinc. Moreover, poplar buds possessed the highest antioxidant capacity both on vitamin C and E calibration curve, evidencing the rich content in such antioxidants. Therefore, based on the valuable nutritional composition confirmed through this study, poplar buds, turmeric and ginger can be recommended as phytogenic feed additives for poultry nutrition.

breeds
Abstract: It was studied the main indicators of the functionality of reproductive system and their interrelation with the productivity indices of imported cows populations Holstein breed, belonging to 3 ecological types: the Dutch, the French and the German and our indigenous Moldovian type Black-Motley breed. The service period, was the shortest in cows of Moldovian type of Black-Motley breed with 38.1 days (P˂0.001), 30.2 days (P˂0.001) and by 14.5 days (P˂0.01.), compared to the Holstein German, Dutch and French ecological types, respectively. The difference of the duration of calvings interval between indigenous population and French ecological type was 18.2 days (p<0.01), compared to the German 46 days (P<0.001) and to the Dutch 36,5 days (P<0.001). There has been a difference of 9,9% in birth coefficient, between Moldovian type and Holstein German ecological type (p˂0.05). The best result of the coefficient of reproductive capacity has the indigenous type, opposite of German ecological type, which has the lowest performance (P˂0.001). Between the service period and the productivity indicators of the milk, regardless of the origin of the animal populations, were predominantly established, authentic positive correlative interrelationships, from weak to strong and statistically negative between productivity indices and the coefficient of the reproductive capacity of cows.

- Effect of dietary inulin on the antioxidant profile of broiler chickens’
meat raised in heat stress conditions
Abstract: The study aimed to assess the effect of dietary inulin (1% dietary inclusion) supplements on broiler chickens’ meat antioxidant compounds. The experiment was carried out under heat-stress conditions, on 60 Ross 308 broiler chickens. The study took place in an experimental hall with digestibility pens and controlled humidity, ventilation and light regime. Each treatment (2 groups, C and E) was replicated 6 times with 5 chicks per replicate pen with ad libitum feeding and free water access. At 42 days old, 6 birds from each group were slaughtered and breast and thigh meat samples were collected. The presence of inulin in broiler chickens’ diets had a beneficial effect by increasing the iron and zinc concentrations in thigh samples. Regarding liposoluble antioxidants, the presence of inulin in diets from tissue samples had an antagonistic effect: increased concentrations of xanthophylls were registered in thigh meat and an adverse effect was noticed in breast meat while an inverse effect was noticed for vitamin E. At the thigh meat level, the antioxidant capacity was significantly improved under inulin influence. In conclusion, the nutritional quality of broilers meat (thigh meat) was improved, for the group fed with inulin-supplemented diets.

- Grape by-products and their efficiency in alleviating the intestinal
disorders in post-weaning piglets
Abstract: The post-weaning period is very stressful for piglets, leading to a transitory inflammation, alterations in the intestinal barrier, oxidative stress and a higher susceptibility to intestinal diseases with economic losses. The finding of new nutritional alternatives with anti-inflammatory, anti-bacterial, anti-oxidant properties is a challenge in post-weaning piglet’s nutrition. Of these strategies, those based on agro-industry wastes rich in bioactive compounds are promising, the increasing number of studies focusing on the use of these wastes as successful modulators of post-weaning – associated disturbances in piglets. This review describes the role of grape by-products in the modulation of inflammation, reinforcement of the intestinal barrier and their role as antioxidant factors. Also, their in-depth intracellular mechanisms of action related to their anti-inflammatory, antioxidant properties are described.

- Influence of partial feeding of orange fleshed sweet potato root meal on
the blood indices of finisher broiler chickens
Abstract: A six-week study was conducted to evaluate the effects of partial replacement of maize with Orange Fleshed Sweet Potato (OFSP) root meal on the haematological parameters and serum biochemistry of broiler chickens at finisher phase. One hundred and eight (108) day old broiler chicks were randomly allotted into 4 dietary treatments (T1, T2, T3 and T4) with 3 replicates each and 9 birds per replicate. The test ingredient, OFSP root meal was included in broiler finisher diets as replacement for maize at 0%, 6%, 12% and 18% in the dietary treatments respectively. The study revealed no effect on all the haematological parameters. The result of the serum biochemistry also showed no significant differences (P>0.05) on all the parameters measured with the exception of triglycerides, globulin and blood urea nitrogen with significant decrease in the triglycerides (mg/dl) and globulin (g/dl) content of T2(24.80 and 0.37), T3(47.01 and 1.07) and T4(48.50 and 1.41) respectively as compared with the control group (61.54 and 1.95 respectively). Therefore, inclusion of OFSP root meal up to 18% did not negatively affect the haematological parameters of the birds and also reduced the risk of metabolic diseases in the birds while improving the cardiovascular health of the birds.

- Production performance and blood parameters of laying hens fed diets with
rosehip and flaxseed meal ingredients
Abstract: This study was conducted to test the effect of two levels of rosehip meal used together with flaxseed meal on weekly production performances and blood parameters of laying hens. For that, we conducted a trial for 5 weeks on 120 laying hens (Tetra SL hybrid), aged 29 weeks. All three diets had 17.50% crude protein and 2780Kcal/kg metabolizable energy, but compared to the control diet (Con) the experimental diets contained 1.5% rosehip meal and 7% flaxseed meal (Diet1) or, 3% rosehip meal and 7% flaxseed meal (Diet2). The results revealed that only feed intake was significantly (P=0.0001) affected, being lower in experimental groups. Among the haematological parameters, the heterophile were significantly higher (P=0.0377) in both Diet1 and Diet2 groups versus the Con group. From the biochemical parameters analysed, in the lipid profile, glucose and triglycerides were significantly lower in the Diet2 group compared with both the Diet1 and Con groups. Total bilirubin was significantly higher (P=0.0020) in the Diet1 group compared to the Con and Diet2 groups, while the lactate dehydrogenase was lower (P=0.0414) in the samples of the Diet2 group. Overall, the studied ingredients had a slight influence on production performances and improved some blood parameters, especially the lipid profile of the Diet2 group.

- Haemo-thermoregulatory response of wallowed and non-wallowed geese during
low temperature humidity index
Abstract: Haemo-thermoregulatory response of twenty-six adult geese comprising of 12 males and 14 females randomly allotted to four groups (Wallowed males, non-wallowed males, wallowed females and non-wallowed females) in a completely randomized design for seven weeks was evaluated. Wallowing was done every alternate day. Respiratory rate (RR), rectal temperature (RT) and pulse rate (PUR) were recorded. On days 1 and 49, blood samples (3mL/geese) were collected from geese in each group and analysed for haematological parameters using standard procedures. There was no sex effect on the RR and PUR but significantly (p<0.05) higher RT was observed in males (40.69°C) compared to females (40.53°C). The RR, RT and PUR were not significantly affected by wallowing. Interactions effect between sex and wallowing on RR, RT and PUR was not significant. Only platelet counts were significantly higher in females (17.70) than males (14.68). Wallowed Geese had significantly lower packed cell volume (37.46±5.13%), haemoglobin (11.85±1.69g/dl) and monocytes (2.81±0.63%) than other treatments. Wallowed Female geese had significantly lower haemoglobin (10.93g/dL) and monocytes (2.86%) compared to those without wallow treatment. Therefore, wallowing has mild influence on the thermoregulatory and haematological indices of geese reared under low temperature-humidity index during non-breeding season.

- Development of dual-purpose cross for meat and egg production I. Growth
performance and carcass composition of the crossbred chickens in
comparison to the parent lines
Abstract: The aim of the study was to develop a dual-purpose cross suitable for rearing in alternative systems and to examine its growth performance and carcass composition in comparison to the parent lines. The experiment was carried out in the experimental poultry farm in the Institute of Animal Science - Kostinbrod. The cross was developed using females of a layer type line L and cocks from line BB. The latter was based on Bresse Gauloise that is also dual purpose but mainly used for meat. The chickens from the lines and the cross were reared in mixed-sex groups on deep litter, at stocking density of 25 birds/m2, and fed with standard broiler feed until the age of 9 weeks. Then the males were separated and sent to slaughter while the females were left for layers. Crossing hens from layer type line L with BB cocks resulted in dual-purpose chickens with a live weight and feed efficiency that were better in comparison to L line, but lower when compared to the BB line. These parameters were however, lower than the typically observed in this type of poultry. Nevertheless, the chickens displayed good carcass composition and deposited low content of abdominal fat, thus revealing good potential to be successfully realized in market.

- Effect of leaf meal on the reproductive indices of male rabbits
Abstract: The study evaluated the effect of Vernonia amygdalina leaf meal on semen indices, serum testosterone and sperm reserve of male rabbits. Forty rabbit bucks were randomly assigned into four groups and fed the experimental diets containing Vernonia amygdalina (VLM) at 0, 5, 10 and 15 % levels for 84days. Reproductive indices were evaluated using standard procedures. Data obtained were subjected to analysis of variance at p<0.05. All semen in rabbits fed 0, 5 and 10 % VLM had milky colour while 14.8% light green and 85.2% milky semen colour was observed in bucks fed 15%VLM. Libido score reduced in rabbits fed VLM diets. Bucks fed 15%VLM had significantly higher semen volume (0.47ml). VLM had no significant effect on spermatozoa mass motility, progressive motility and sperm concentration. Live sperm cells significantly increased in bucks fed 5 and 10% VLM diets. VLM had significant (p<0.05) effect on spermatozoa morphology. Vernonia amygdalina leaf meal had no significant (p<0.05) impact on testosterone, testicular and epididymal indices. In conclusion, up to 10%VLM can be adopted as feed ingredient for male rabbit breeder stock without deleterious effect on reproductive indices.

- The effects of diets incorporating natural source of tannins on laying
hens’ production performances and physical parameters of eggs
Abstract: This study aimed to evaluate the effects of natural tannins in laying hens’ diets on production parameters and the alterations of eggs’ physical properties during storage time and temperature. A six weeks experiment was carried out on 168 Lohmann Brown laying hens, 51 weeks of age, accommodated within digestibility cages, structured on 3 levels. The dietary basic structure was the same for all 3 tested groups. The difference between the experimental and control groups was established by the type of plant additive added E1 (0.5% chestnut flour) vs. E2 (0.5% bark oak). At the end of the experiment, 36 eggs/group were collected to evaluate internal and external quality parameters of eggs during storage. These eggs were divided into two parts: 18 eggs/group were kept at room temperature (22°C) and 18 eggs/group were kept in the refrigerator (4°C) for 42 days and analysed to determine shelf time. The results obtained showed that the physical parameters of eggs laid by hens fed with diets supplemented with natural source of tannins (chestnut powder and oak bark) were improved in terms of Haugh Units, yolk colour and eggshell thickness, but only in refrigeration storage conditions.

- Semen characteristics and fertility response of crosses between white and
black plumage indigenous turkeys under artificial insemination
Abstract: Semen quality and fertility in crossbreeding between white plumage and black plumage indigenous turkey hens using artificial insemination were investigated. Eighty-two healthy indigenous turkeys, comprising 72 hens (Thirty-two black and forty white) and 10 toms (five black and five white) were used. The turkeys were grouped into four treatments based on the breeding plans: T1 (White toms X White hens), T2 (Black toms X Black hens), T3 (White toms X black hens) and T4 (Black toms X White hens). Semen was harvested from white toms, pooled, and inseminated at 0.02ml into hens in T1 and T3. Semen harvested from black toms were also pooled and inseminated at same dose into hens in T2 and T4. White tom semen quality parameters were 97%, 91%, 96%, and 532×106 cells/mL for mass activity, motility, livability, and sperm concentration, respectively. Black tom semen quality parameters were 91%, 93%, 95%, and 293×106 cells/mL for mass activity, motility, livability, and sperm concentration, respectively. Egg fertility were 99.63% in T1, 99.81% (T2), 99.84%(T3), and 99.27% (T4). Hatchability in T1, T2, T3, and T4 were 57.67%, 72.54%, 67.65%, and 64.82%, respectively. Besides sperm concentration, semen quality parameters and fertility in indigenous turkey were not affected by plumage colour

- Potential and challenge assessment of tannin extracts from black tea in
male rabbits fed contaminated diet by Mycotoxins
Abstract: The focus of this research was to investigate how tannin extract from black tea influenced the hematological and histopathological evaluations of male rabbits fed a mycotoxin-contaminated feed, including 17 ppb aflatoxin, 5 ppb ochratoxin and 2 ppb fumonisin. A total of 28 local male rabbits were allocated into four groups, the first of which was a control group. The second was fed a Mycotoxin-contaminated meal. The third was given a Mycotoxin feeding with tannin extracts (125mg/mL per head) administered orally, while the fourth was fed a Mycotoxin contaminated diet with tannin extracts (250 mg/mL per head) given orally. The findings revealed that tannin extracts seemed to have a significant positive impact on haematological results, particularly RBCs and WBCs, throughout the period; however, the 250 mg/mL dose showed no significant differences in Hb levels. Nonetheless, as compared to the Mycotoxin group, the histopathological sections of tannin extract demonstrated a reduction in the toxicity of the Mycotoxin diet on the liver and kidney tissues; conversely, the tissue sections of the control animals showed no abnormalities. In male rabbits fed contaminated Mycotoxin diets, tannin extract from black tea was found to have a favourable impact on hematological activities and vital organs such as the liver and kidney.

- Assessing the efficiency of using a local hybrid of rye for broiler
chickens aged 1–42 d, with emphasis on performance and meat quality
Abstract: This study was conducted to test the hypothesis that a new rye hybrid produced in Romania (Suceveana variety) could not impair the performance and meat quality of broiler chickens. A total of 360-day-old male Ross 308 broiler chicks (40.1±2.3 g) were randomly assigned to 3 dietary treatments replicated 6 times having 20 birds per replicate. Experimental diets were formulated to replace 25 and 50% of corn with rye (RYE 25 and RYE 50, respectively) as energy-yielding sources, whereas the control diet (CON) was 100% corn-based. All diets were formulated to be isocaloric and isonitrogenous, with similar total lysine and total sulfur amino acids. The results indicated similar outcomes of the local rye hybrid to commonly used corn-containing diets in terms of performance and carcasses. There were no differences in fundamental physicochemical (i.e., pH, protein, fat, moisture) or textural attributes of breast muscles due to dietary treatment, as well. However, the substitution of corn with rye reduced (P = 0.008) abdominal fat associated with an increase in CIE color (P< 0.001). Thus, the Suceveana rye hybrid can be included in broiler diets, from hatching to day 42, without any adverse effects on the bird’s performance.

- The effects of minor oilseeds cakes on rumen metabolism and productive
performances of ruminants
Abstract: The article focuses on the chemical composition, nutritional value and the effects of four minor oilseeds’ cakes when used in ruminants’ nutrition. Although less abundant than the well-known major oilseeds, mechanical extraction of oils from the minor oilseeds retrieves important quantities of cakes which, beside a high content of crude protein have variable, yet important proportions of residual fat, upon the efficiency of the extraction processes and retains some nutritional properties of the seeds, including the content in bioactive substances.The browse of the literature on minor oilseeds cakes retrieved scattered and contradictory data, implying a need for systematic comparison, among them and against a reference feed. Although specific literature is scarce, a number of articles reported the chemical composition of the four cakes, allowing their hierarchization and their comparison with the rapeseed cake, considered as reference feed.On the other hand, the review identified numerous knowledge gaps, concerning the effects of the four cakes on rumen metabolism and their effects on animals’ productive performances. However, the literature review confirmed that the four cakes can be good substitutes of rapeseed cakes or similar feeds in ruminants’ nutrition, as long as the potential effects of bioactive substances taken into consideration.

- Effects of dietary supplementation with herbal extract as methionine
replacer on growth performance, meat composition, oxidative stability and
liver gene expression in broiler chickens
Abstract: In the present study, an herbal feed additive was tested for partial-to-complete replacement of synthetic methionine in poultry diets, along with its effects on performance, breast and thigh meat chemical composition, oxidative stability during refrigerated storage and the expression of five target genes in liver. In a 35 days trial, 600 one-day-old male chicks were randomly allocated to 4 groups with 10 replicates. Birds in the control group were fed a regular maize–soybean-based diet that covered DL-methionine needs while the second group (Meth40) was similar to control but contained only DL – Methionine at 40% of control diet. Diet in third group contained DLMethionine at 40% of control and the herbal feed additive Methiorep TMMeth40+Mrep) with extracts of Boerhavia diffusa, Azadirachta indica, Vigna mungo and Trigonella foenum-graecum. Diet of fourth group was formulated to totally replace DL Methionine by Methiorep TM (Mrep). Body weight gain and feed consumption were weekly recorded. At the end of the trial, all birds were slaughtered and 2 chickens per pen were selected for meat and liver sampling. The liver was tested for the expression of five target genes, namely Methionine synthase (MTR), Tyrosine aminotransferase (TAT), Spermidine synthase (SMS), Methionine sulfoxide reductase (MSRB1) and Betaine homocysteine S-methyltransferase (BHMT). The results showed that the Meth40 group had reduced body weight compared to the Meth40+Mrep group while the Control and Mrep groups had comparable weights. Feed intake and feed conversion ratio did not differ among the experimental groups. Carcass, breast and thigh meat yield were higher in the Mrep and the Control compared to Meth40 and Meth40+Mrep groups. Also, meat oxidation was significantly lower in herbal groups compared to the control group. After normalization to β-actin expression, quantitative real-time PCR analysis revealed an induction in the expression of MTR and SMS genes in the liver of both herbal treated groups. No changes were observed for the TAT, MSRB1and BHMT genes in the herbal treated groups compared to the control or the Meth40 group. In conclusion, herbal feed additives with specific plant extracts may be able to improve both growth performance and antioxidant activity of broiler chickens, phenolic content; yet, they may also support in amino acid efficient use of broiler.

- Effect of agro-industrial by-products on inflammation and oxidative stress
using an in vitro cell model
Abstract: Agro-industrial by-products can play an important role in the animal feeding, being an alternative to conventional raw materials. These two wastes can be considered as important sources of bioactive compounds that can be used in animal feed with multiple benefits for animal health. This study has investigated the anti-inflammatory and anti-oxidant in vitro capacity of grape seed and sea buckthorn meals, as waste resulted from the oil industry in order to be used in swine nutrition. The in vitro study was realised on swine peripheral blood mononuclear cells challenged with LPS and treated or not with grape seed meal and sea buckthorn meal extracts. Our results show that both extracts have the capacity to attenuate the inflammation and oxidative stress induced by LPS. The effect induced by the grape seed meal extract was in majority of cases more important than of the sea buckthorn, this effect might be due to a different composition in bioactive compounds (polyphenols, PUFA etc) of the two extracts.
