This research aimed to evaluate the quality of vermicompost produced from cattle manure at different levels of moisture content. For this purpose, cattle manure containing different moisture content such as 60% moisture (T1), 70% moisture (T2) and 80% moisture (T3) treatments were adopted with 3 replications. A total of 9 vermicomposting pits were filled with 25 kg of cattle manure, each having the same amount of red worms. Parameters studied were dry matter (DM), crude fibre (CF), crude protein (CP), ether extract (EE), ash and pH. Results showed that 63% DM was increased in T2 and this value was significantly higher than T1 and T3 (p> 0.05). The rate of CF degradation was 46, 78 and 72% in T1, T2 and T3, respectively. The CF degradation was also significantly higher in T2 compared to the other two treatments (p> 0.05). In the case of CP, a slightly higher CP was found in T2 followed by T1 and a little bit lower in T3 after 60 days of vermicomposting period. The EE content was slightly higher in all 3 treatments after 60 days of vermicomposting, but this difference was not significantly different among the treatments. The ash content was slightly higher in all 3 treatments after 60 days of vermicomposting, but this difference was also not significantly varied. The pH was significantly differed with the 3 treatments after 60 days of vermicomposting. From the above results, it was revealed that T2 would be the suitable level of moisture for CF degradation and increased CP content in the final vermicompost. Therefore, it might be concluded that cattle manure containing 70% initial moisture would be a good option for vermicomposting. Bangladesh Journal of Animal Science. 2022. 51 (2): 40-46

This study was conducted to compare the effects of different feed additives namely, organic acid (citric acid), probiotic (navio plus), and antioxidant (Bio-Sel-E) on the growth performance and nutrient digestibility in growing rabbit to convey a clear message on the use of one specific additive in rabbit diet. Thirty-two crossbred New Zealand White growing rabbit (four to five weeks of age) were randomly assigned to four different groups and reared for a period of fifty six days. Rabbit were fed on green grass (Hymenachne pseudointerrupta) and concentrate mixture (2703 Kcal ME/kg, 16.91 % CP). Additives were added at the top of the concentrate mixture, except for the control group. Compared with the control group, rabbit fed different additives showed 9–13% higher growth rate and 7–11% greater growth velocity; and probiotic supplemented group showed the best result (P<0.05) in terms of FCR value. Carcass weight (%) increased significantly in probiotic supplemented group, but numerically in organic acid and antioxidant supplemented groups compared with control group. Abdominal fat (%) was significantly decreased in organic acid, probiotic and antioxidant supplemented groups compared with control, however, lowest value (%) was recorded in probiotic supplemented group. Probiotic showed significant effect on pH decreasing trend in ingesta sample up to small intestine. Crude protein digestibility co-efficient (%) value was significantly higher in probiotic supplemented group, but numerically in organic acid and antioxidant supplemented groups compared with control group. Overall results indicated that, among the three different additives: organic acid, probiotic and antioxidant, probiotic may be considered as the best one for the better performance and nutrient digestibility in growing rabbit.

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

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.

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.

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.

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. \u0000Bangladesh Journal of Animal Science. 51(1):31-39. \u0000 ","PeriodicalId":8873,"journal":{"name":"Bangladesh Journal of Animal Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84246558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

The purpose of the study was to determine the quality of whey obtained from cow milk using different types of coagulants (microbial rennet, calf rennet, lactic acid and papaya latex). The quality of whey was evaluated with the help of chemical and microbial tests. Results revealed that maximum whey yield (765 mL/L milk) was obtained from lactic acid coagulation which was 17 mL higher than that of the microbial rennet coagulation (p=0.000). The pH was found significantly (p<0.05) higher when the microbial rennet was used as coagulants. Whey obtained by the lactic acid coagulation was superior in terms of chemical quality compared to the whey obtained by coagulating action of other coagulating agents (p=0.000-0.001). Total solids and lactose content was found highest (7.2% and 4.8%, respectively) in lactic acid whey which was significantly higher (≈1%) than that of the other types of whey (p=0.000). In addition, protein content was also found higher (p<0.05) in whey obtained by lactic coagulation. On the other hand, efficiency of fat and ash recovery in curd was found lowest in calf rennet (p=0.000) among the studied coagulants. However, phosphorus content was highest (p=0.005) in calf rennet whey and the whey obtained by microbial rennet coagulation had the lowest (p=0.000) calcium concentration. Microbial load was found maximum (117 cfu × 104/mL) in whey drained out in microbial rennet coagulation, whereas, papaya latex whey had the lowest count (78 cfu × 104/ml), and the microbial count of other two whey was intermediate of them (p=0.000-0.001). In general, considering all the quality attributes, lactic acid whey was found better followed by calf rennet and papaya latex. It indicates more nutrient recovery in the curd produced by the microbial rennet. Bang. J. Anim. Sci. 2021. 50 (2): 107-113

The experiment was carried out to investigate the effects of neem (Azadirachta indica) leaf powder (NLP) over a period of 35 days on the growth performance, dressing parameters, serum biochemical parameters and profitability of broiler meat. Day old broiler chicks (n = 320) were randomly assigned to five dietary groups, each with four replicates. The dietary treatment groups were; control (basal diet; no additives), antibiotic (basal diet + antibiotic), NLP 0.25% (basal diet + 0.25% NLP), NLP 0.375% (basal diet + 0.375% NLP) and NLP 0.50% (basal diet + 0.50% NLP). Results showed that the body weight, body weight gain, feed intake and FCR were differed significantly (P<0.05) among the treatment groups. Body weight and body weight gain were higher in antibiotic, NLP 0.25% and NLP 0.375% group compare to the NLP 0.50% group. Total feed intake was not different significantly (P>0.05). Better (P<0.05) FCR was observed in NLP 0.25% group as such as antibiotic group compare to the control and NLP 0.50% group. The results also showed that dressing parameters were not significantly (P>0.05) different among the dietary groups. Serum glucose, triglyceride, GOT, GPT and cholesterol level were non-significant (P>0.05) among the dietary groups. However, HDL was significantly (P<0.05) higher in NLP 0.25% group compared to the control group. Higher profitability was found in NLP-0.25% group and antibiotic group when all the birds were sold at market price. It can be concluded that the addition of NLP to broiler diet had a positive effect on growth performances but no negative effect on dressing parameters and serum biochemical parameters. Moreover, NLP at the level of 0.25% increases HDL level and improve profitability. It can be suggested that neem leaf powder up to 0.375% could be potential feed additive in broiler diet. Bang. J.
