ABSTRACT The present study was conducted with a view to knowing the reproductive performance of indigenous buffaloes at Sreemangal Upazila under the Moulovibazar district. Data were collected on a regular basis in 2021 from thirty (30) families by written interview paper. Out of 30 families; 26 own 33 milch buffaloes, 17 dry buffaloes, 12 heifer calves, 7 bull calves, and 10 bullocks were counted for calculation. This study demonstrated that the distribution of buffalo populations was scattered and the average buffalo populations were 3.038 per house-holds. The evaluated reproductive performance of indigenous buffaloes found the age at puberty was 44.06 ± 2.13 months, lactation length 204.70±20.68 days, milk yield 1.88±0.702 liters/day, gestation period 307.00±2.11 days, body weight 27.26±1.55 kg/calf, age at first calving 53.84±1.48 months, calving interval 1.72±.548 years and the average post-partum heat period was 147.6±18.68 days. The study revealed that the reproductive performance of the buffaloes was varying among breeds, farms, locations, areas, seasons, and management in the study area. In a concrete manner, this study gives a complete scenario of the reproductive performance of indigenous buffaloes at Sreemangal Upazila under the Moulovibazar district of Bangladesh which is strictly controlled by genetic and non-genetic factors.

The study was undertaken to evaluate the slaughter house goat ovaries, follicle and cumulus-oocytecomplexes (COCs) with the view of in vitro production of embryos. Goat ovaries were categorized as right, left, with corpus leutum (CL) and without CL group. Ovaries were then evaluated on the basis of weight (gm), length (cm), width (cm), total number of follicle on the surface of each categorized ovaries, number of follicle aspirated, total number of COCs, normal COCs and abnormal COCs. The length (cm) of right ovaries (1.19±0.09) was found significantly (p<0.05) higher than left ones (1.15±0.04). The number of normal oocyte was found significantly higher (p<0.05) in left ovaries (1.18±0.10) then right ovaries (1.11±0.09). Other parameters, including width, weight and total number of COCs aspirated per ovary did not differ significantly (P<0.05) between right and left ovaries. When compared the ovaries in between with-CL and without-CL group, significantly (p<0.05) higher number of normal COCs (1.12±0.07) were found in without-CL group with an increase of length (1.17±0.01), total number of follicles (5.21±0.03), number of aspirated follicles (2.74±0.12) and total number of COCs (1.99±0.14), but decrease in weight (0.66±0.03), width (0.76±0.02) and abnormal COCs (0.87±0.15) per ovary. Therefore, it could conclude that, both right and left ovaries is great source for large number of oocyte and without-CL ovaries is considered as a suitable source to supply quality oocyte for in vitro embryo production of goat.

This study was conducted to investigate the effects of different levels of black cumin seeds (Nigella sativa L.) on egg production and cholesterol concentration in egg yolk of laying hens. A total of 60 commercial layer strain day old layer chicks were collected and divided into three groups treated with 1.0%, 1.5% and 2.0% black cumin inclusion. The concentrations of total lipids, total cholesterol, phospholipids and triacylglycerols in serum and egg yolk were measured. Feeding of the diets with 1%, 1.5% and 2% black cumin seeds during the laying period found egg yolk cholesterol by 11.12, 9.88 and 9.83 mg/g respectively. The results found that feed efficiency ratio, egg production, body weight, feed intake and egg weight were nonsignificant between the treatments. However, egg yolk cholesterol concentration was found that 1.5% and 2.0% black cumin in diet were reduced cholesterol concentration insignificance (P<0.05). So, dried black cumin supplementation in diets had no any adverse effect on egg production and egg weight. Furthermore, egg yolk cholesterol concentrations were decreased. Hence, it is concluded that black cumin (Nigella sativa L.) seeds and/or the active principle are of interest as potential egg-yolk cholesterol-lowering agents.
