An experiment was conducted to determine the biomass yield, chemical composition and in-sacco dry matter (DM) degradability of 10 cultivars (WRF-7, TSN-111, TYT-03, TYT-05, TYT-06, TYT-08, TYT-12, ITYN-10, ITYN-14 and ITYN-15) of triticale fodder. The fresh yield of different cultivars of triticale was ranged from 5.03 to 6.85 (t/ha). The organic matter (OM), crude protein (CP), acid detergent fibre (ADF), neutral detergent fibre (NDF), calcium (Ca) and phosphorus (P) contents of different cultivars of triticale were found 89.62 to 91.78 %, 21.34 to 25.99 %, 23.09 to 29.99 %, 46.77 to 50.80 %, 0.42 to 0.61 % and 0.33 to 0.41 %, respectively. The yield of DM and CP of different cultivars of triticale were varied from 0.77 to 1.44 (t/ha) and 0.193 to 0.351 (t/ha), respectively. Among different triticale cultivars the highest OM and CP contents were found in TYT-12 (91.78 %) and ITYN-10 (25.99 %), respectively. The highest NDF and ADF contents were found in ITYN-14 (50.80 %) and TYT-05 (29.99 %), respectively among different cultivars. The contents of Ca and P in ITYN-10 (0.61 %) and ITYN-14 (0.41 %), respectively were found to be the highest among the cultivars. Potential DM degradability observed in different cultivars of triticale was higher in ITYN-14 and TYT-05 (84.81 and 81.88 %, respectively) compared to others and relatively poor degradability was found in TSN-111 and TYT-03 (60.74 and 61.35 %, respectively). Therefore, it may be concluded that, the cultivar ITYN-10 will be the promising one due to comparatively higher fresh yield, organic matter (OM), crude protein (CP), neutral detergent fibre (NDF), calcium (Ca) and phosphorus (P) content and less acid detergent fibre (ADF) fraction cultivated for fodder production in Bangladesh.http://dx.doi.org/10.3329/bjas.v41i1.11972

Generally, consumers prefer the indigenous chicken meat compare to commercial chicken like sonali or broiler chicken because of their concept of having more nutritious and palatability and ready to pay more. Whether the concept is true or not, and on which aspects, indigenous chicken meat is superior compare to that of commercially reared chicken, validation is required. Therefore, an experiment was conducted to compare the carcass characteristics, meat proximate composition, physico-chemical parameters and sensory attributes of indigenous/deshi, sonali and broiler chicken that are available in the poultry market of Bangladesh. Three types of finisher chicken: indigenous/deshi, sonali and broiler chicken were bought from local market of Bangladesh. Birds were slaughtered following halal method; carcass traits and meat quality parameters were analyzed after collection and processing of meat samples. Result indicated that, there is a variation in the carcass characteristics, proximate composition, physico-chemical attributes and sensory evaluation. Broiler chicken live weight, slaughter weight and abdominal fat was higher as compared to sonali and indigenous/deshi chicken (P<0.05). The dry matter, crude protein and ether extract was higher in deshi chicken followed by sonali and broiler chicken (P<0.05). Drip loss and cooking loss was higher in broiler chicken followed by sonali and deshi chicken, while pH24 was lower in deshi chicken followed by sonali and broiler chicken (P<0.05). Broiler chicken meat was more tender in relation to sonali and deshi chicken (P<0.05), where flavor of deshi chicken meat was higher as compared to the broiler chicken (P<0.05). Result suggested that, based on level of status of people, consumers can choose indigenous or deshi chicken due to better proximate composition and meat flavour; however, sonali and broiler chicken are also acceptable by the consumers with higher carcass weight and meat tenderness with short interval to become marketable weight and cheap price which can be afford by all class of people to meet their protein demand, eventually can secure national human health.

Bio-slurry is considered as a good quality organic fertilizer in Bangladesh agriculture. An experiment was conducted at Bangladesh Agricultural University, Mymensingh to assess the effect of bulking materials over the composting of bio-slurry. The experiment was conducted with 4 treatments each of 3 replications. The treatments for compost preparation were, T0 (50% Bio-slurry + 50% manure), T1 (50% Bio-slurry + 50% manure and saw dust), T2 (50% Bio-slurry + 50% manure and rice straw), T3 (50% Bio-slurry + 50% manure and tree leaves). Compost moisture, pH, temperature and C: N ratio was assessed every week. Maximum temperature found in T1 (34.030C) and other treatments showed a slower rise in temperature.  Highest C:N ratio (19.30) was obtained in T3. The pH of the compost was significantly influenced by saw dust which ranged from 8.28 in T2 to 8.74 in T1. Moisture content of compost was significantly influenced by bulky materials and ranged from 56.34 to 68.83. At 42 day the highest crude fiber was obtained in T2 (25.16%). The results suggest that bulky materials treated bio-slurry can be good compost which will be very effective to soil and crops. Bang. J. Anim. Sci. 2020. 49 (2): 142-150

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
