The Growth Performance of Black Bengal goat in Village Condition of Bangladesh

Abstract

The study was conducted about the growth performance of Black Bengal goat in village condition at Savar Upazila under the Dhaka District from June/2017 to April/2018. Least-squares means for body weights at birth, 3, 6, 9 and 12 months of ages were 1.10, 5.02, 8.41, 10.41 and 12.42 kg respectively. Sex has highly significant (p < 0.01) effect on the body weight at 3 months (5.22 ± 0.04 and 4.77 ± 0.04 kg), 6 months of ages (8.74 ± 0.04 and 7.96 ± 0.04 kg) and sex has significant (p < 0.05) effect on the body weight at 9 months (10.66 ± 0.09 and 10.10 ± 0.10 kg) and 12 months (12.88 ± 0.06 and 11.82 ± 0.07 kg) respectively male and female. Type of birth has highly significant (p < 0.01) effect on body weight at birth, 3, 6, 9 and 12 months. Parity has highly significant (p < 0.01) body weight at 3 months (4.95 ± 0.05, 5.04 ± 0.04 and 5.08 ± 0.05 kg) and 12 months (12.21 ± 0.67, 12.39 ± 0.08 and 12.67 ± 0.07 kg) and significant (p < 0.05) effect at birth weight (0.94 ± 0.01, 0.95 ± 0.01 and 0.97 ± 0.01 kg) and 6 months body weight (8.29 ± 0.06, 8.37 ± 0.05 and 8.54 ± 0.05 kg) respectively at 1 st , 2 nd and 3 rd parity. Season has a highly significant (P < 0.01) effect in birth weight (0.91 ± 0.01, 0.99 ± 0.01 and 0.97 ± 0.01 kg), 3 months (4.87 ± 0.04, 5.22 ± 0.04 and 4.89 ± 0.06 kg), 12 months (12.21 ± 0.06, 12.65 ± 0.07 and 12.30 ± 0.10 kg) and season has significant effect (P < 0.05) at 6 months body weights (8.20 ± 0.04, 8.63 ± 0.05 and 8.23 ± 0.07 kg) respectively in winter, summer and rainy season. It can be concluded that male type of sex, single type kid, third parity of dam and summer season was better.

Effect of pre-and post-partum feed supplementation of Maraz does on the productive performance of their offspring

“…It is generally confirmed by many workers that male kids are significantly heavier and have a higher growth rate than females [21, [27][28][29]. The superiority of males over females in terms of body weight and daily gain in weight might be attributed to androgen acts as an anabolic hormone [27,28]. Who also stated that males are more aggressive and active than females, and may consume more milk and feed.…”

“…Male kids exceeded females significantly (P<0.05, Table 1) in their birth weight (2.4 vs. 1.8 kg), weaning weight (12.5 vs. 7.1 kg), weight at 6 months (16.5 vs. 10.6 kg), weight at 9 months (21.2 vs. 14.7 kg), and pre-weaning (111 vs. 57 g/d), postweaning (48 vs. 42 g/d) and total growth rates (69 vs. 48 g/d). It is generally confirmed by many workers that male kids are significantly heavier and have a higher growth rate than females [21, [27][28][29]. The superiority of males over females in terms of body weight and daily gain in weight might be attributed to androgen acts as an anabolic hormone [27,28].…”
