The present study was conducted with a view to know the productive and reproductive parameters of

Characterization of Black Bengal bucks and does was performed in this study. A total of 50 goats of different aged were studied. The experiment was performed in Black Bengal bucks and does at 1 st day and at 3, 6, 9 and 12 months of age for measuring different parameters such as body length, heart girth, wither height, hip height, fore and hind leg length, head length and width, head length and width, ear length and ear breath, scrotal length and scrotal circumference. In a single parameter as body weight of Black Bengal bucks and does at 1 st day and at 3, 6, 9 and 12 months of age were found to be 1.08±0.06, 5.22±0. 33, 8.95±0.34, 12.05±0.47 and 14.20±0.20; and 1.01±0.23, 3.93±0.19, 7.41±0.27, 9.53±0.38 and 12.40±0.41 kg respectively. Whereas all the finding where gradually increased for all parameters according to their specific age periods. Body weight has a strong positive relationship with heart girth, body length, height at wither, scrotal length and scrotal circumference in Black Bengal goat. All the parameters studied found comparatively higher in bucks than does.

The experiment was conducted on “Lohman Meat” broiler chicks to evaluate the effect of exogenous multivitamin and enzyme supplementation on body weight gain, haematological parameters (TEC, Hb content, PCV and ESR) and serum transaminases (AST and ALT). A total of 20, twenty days old broilers were randomly divided into four equal groups (5×4). Group A was considered as control, fed only with commercial ration, group B was treated at a dose rate of 0.5 ml multivitamins per 1 litre of drinking water, group C was treated at a dose rate of 1 ml enzyme per litre of drinking water and group D was treated with multivitamin @ 0.5 ml/L and Enzyme @ 1ml/ L in water from 1 to 21 days of experiment. It was observed that multivitamin and enzyme supplementation significantly (p<0.01) increased body weight. TEC, PCV and Hb content increased significantly (p<0.01) in the treated groups as compared to that of control group. ESR, AST and ALT values decreased significantly (p<0.01) in the treated groups. Therefore, it may be concluded that multivitamin and enzyme may be used with better performances in terms of increase of body weight and blood profiles.

This study was aimed for selection of Black Bengal bucks based on their fertility and the performance of their progeny in field condition. Data on buck were collected from a nucleus breeding flock and on progeny at field level. The traits considered were birth weight, weight at every 3-m interval up to 12 m of age. Average daily gain (g/day) on 90 progeny produced from 10 bucks and semen parameters on these bucks were collected. Heritability estimates obtained for birth weight, 3, 6, 9 and 12-m weights and average daily gain of progeny were found to be 0.41±0.08, 0.49±0.07, 0.46±0.08, 0.48±0.28, 0.50±0.09 and 0.49±0.06, respectively. The high heritability estimates of body weights indicated that there is a good opportunity for genetic improvement of this trait in a selection scheme. Heritability estimates obtained for semen volume, sperm concentration, sperm motility, sperm livability and normal sperm were 0.11±0.04, 0.25±0.07, 0.13±0.08, 0.12±0.08 and 0.06±0.03, respectively. The highest non return rate was observed in bucks of 32, 52 and 57 (66.67±6.75%). The lowest was found in buck 48 (41.67±5.65%). Among 10 bucks, first 3 top buck IDs were 52, 57 and 54 on the basis of BV at birth weight. Selection index of bucks for all traits was calculated and bucks were ranked accordingly. The highest selection index of three bucks ID were 52, 7 and 4 (1009.39, 934.595 and 865.808, respectively). It can be concluded that these top ranking three bucks can be selected and conserved for production and preservation of frozen semen for long term use.DOI: http://dx.doi.org/10.3329/bjas.v43i1.19379 Bang.
