Abstract: The study was conducted to identify the socio-economic status and problems faced by the Sonali farmers at Wazirpur Upazila in Barishal District. A total of 90 respondents from 9 unions were selected randomly for primary data collection. The farmers and their farming were evaluated through the analysis of data collected in a pre-structured questionnaire. This study revealed that a maximum portion of the farmers were middle-aged (52.2%), male (92.2%), and had a secondary level of education (54.4%). Most farmers had medium-sized farm (38.9%) and invested their own capital in farming (54.9%). Although major farmers had low experience in Sonali chicken farming, they had high management skills (63.9%). In terms of occupation, the highest percentage of farmers (38.9%) had a conjugated occupation of poultry and crop. Most of the farmers had their own tube-well (74.7%) and use sanitary latrine (71.1%). Nevertheless, only 17% of the farmers had good health condition. About 49% of the farmers had only one chicken house, and 87.8% followed the floor system for rearing Sonali chicken. Surprisingly, all the farms followed an all-in-all-out marketing system for Sonali chicken. Most of the farmers (96.7%) vaccinated their poultry birds and added coccidiostat (73.3%) and vitamin mineral premix (94.4%) to the feed. A major portion of the farmers identified the irregular fluctuation in the market price of feeds (95.6%) and day-old chicks (93.3%) as severe problem, followed by high price of feed but low price of meat (87.8%). A disorganized marketing channel was the next major problem faced by the poultry farmers (83.3%). Taken together, the Sonali farmers of Barishal were middle-aged; poorly educated, and invested their own capital for farming, and they faced a variety of challenges during farming and marketing their chickens. To enhance Sonali farmers’ socio-economic conditions and alleviate their problems, the government should take appropriate steps to provide finance and farm-based training, including modern animal husbandry practices.

Pages: 12 - 16
Abstract: A study was carried out to investigate the effect of different levels of Chhana binder on the sensory and chemical quality of Rosogolla. Therefore, two (02) types of Chhana binders in different percentage such as 3, 5 and 7% wheat flour as well as 3, 5 and 7% rice flour (w/w) were used to prepare Rosogolla to find out a suitable Chhana binder for manufacturing good quality Rosogolla. Based on sensory evaluation, the highest score was obtained from 5% wheat flour and lowest score was from 5% rice flour, might be due to wheat flour contain gluten. From chemical analysis, the protein and carbohydrate content among the samples differed significantly (p< 0.01) and the highest values were noted for 7% wheat flour and rice flour, respectively. The highest and least mean values of moisture content were recorded for Rosogolla obtained from 3% wheat flour and 7% rice flour, respectively. Among different Chhana binder, 5% wheat flour was found best suitable for quality Rosogolla making. Bangladesh Journal of Animal Science. 51(1):12-16

performance of broiler

Abstract: Spirulina is multicellular, blue green algae, which contains protein (50-70%), carbohydrate (12-13%), fat (6%) fat and substantial amount of minerals, vitamins, carotenoids and some fatty acids. Considering nutrient content and prospective health benefits, an experiment was conducted with 144-day old broiler (Cobb-500). Chicks were divided into 6 groups having 24 birds in each (8 per cage). Experimental groups were (1)-0.25% vitamin in feed, (2)-0.25% vitamin in feed + 0.5g/L Spirulina in water from laboratory, (3)-0.25% vitamin in feed + 0.5g/L commercial Spirulina in water, (4)-0.0% vitamin + 0.25% Spirulina in feed, (5)-0.25% vitamin + 0.25% Spirulina in feed, (6)-0.0% vitamin + 0.0% Spirulina in feed. The diets were iso-caloric (3170Kcal/kg) and iso-nitrogenous (22.7% CP). After 35 days feeding trial body weight was 1263, 1294, 1308, 1338, 1372 and 1188g/bird in group 1, 2, 3, 4, 5 and 6 respectively where numerically higher weight was observed in group 5 and lower in group 6, but overall significant variation observed among the groups (p<0.05). Feed intake was 2475, 2302, 2320, 2311, 2342 and 2378 g/bird in group 1, 2, 3, 4, 5 and 6 respectively (p<0.5). Feed conversion ratio (Kg feed intake/kg live weight gain) was higher in group 6 (2.00) and lower in group 5 (1.70), but was overall significant variation observed among the groups (p<0.05). It may be concluded that Spirulina would be supplemented in feed and water separately or at a time for better performance and health status of broiler.

Pages: 25 - 30
Abstract: Semen production from breeding bulls used in Artificial Insemination (AI) program is of great importance in cattle breeding. Good quality semen has positive effect on the fertility of cows and heifers. The aim of this study was to evaluate the quality and assessed as the freezing ability of Red Chittagong Cattle (RCC) bull with fresh-diluted semen and frozen semen. The parameters of semen characteristics included were volume per ejaculate (ml), percentage of mass motility, normal and abnormal sperm, and sperm concentration (million/ml). The highest mass motility was found in bull ID No. 4 and the lowest in bull ID No. 1 but the highest sperm concentration was found in bull ID No. 3 with lowest in bull ID No. 2 in fresh semen. Highly significant (p<0.001) positive correlation was found between mass motility and sperm concentration in bulls of ID No. 3 and 4, a negative significant (p<0.05) correlation was found between mass motility and normal sperm percentage. Two freezing techniques were followed in frozen semen production: Cork sheet freezing and Cryobath freezing with two freezing times 15 and 30 minutes were also applied. Variations in the motility of frozen semen by Cork sheet freezing with two different times were found significant (p<0.05) between bulls. Furthermore, highly significant (p<0.01) difference of motility by Cryobath freezing was found between the bulls. The highest motility after both 15 and 30 minutes Cork sheet freezing and Cryobath freezing was found in bull ID No. 4 and lowest in bull ID No. 3. In the present study, variability in the potentiality of bulls (semen volume and sperm concentration) was observed and found lower than crossbred bulls due to small size of Red Chittagong, an indigenous zebu cattle of Bangladesh.

Abstract: Stature and live weight are economically important traits in livestock species and polygenic in nature. Pleomorphic adenoma gene 1 (PLAG1) is a member of the PLAG family of zinc finger transcription factors which has a specific association with growth related traits in human and various livestock species including cattle. This study investigated the 19-bp indel (insertion/deletion) polymorphism of the PLAG1 gene and its possible association with morphometric traits in indigenous and Holstein-Local (H×L) crossbred cattle of Bangladesh. A total of 160 blood samples were collected from the aforementioned cattle populations whereas data on morphometric traits were recorded only from H×L crossbreds. PCR amplification fragment harboring 19-bp indel detected three genotypes II (366 bp), ID (366/347 bp) and DD (347 bp). The II, ID and DD genotype frequencies were 0.00, 0.09 and 0.91 respectively in indigenous cattle populations and the corresponding frequencies were 0.14, 0.43 and 0.43, respectively in H×L crossbred populations. None of the investigated morphometric traits had a significant association with 19-bp indel genotypes. However, non-genetic factors such as herd, year and parity had significant effects only on hip height trait in crossbred cattle (P<0.001). In conclusion, the identified 19-bp indel polymorphism was temperate breed Holstein specific and was absent in indicine populations that could be utilized only for crossbred cattle of Bangladesh upon validation with large a number of samples.
