ArticleItem Open Access EffEffect of different levels of concentrate feed supplementation on post-weaning growth, carcass traits and economics in salem black Kids(2020-09) Bharathy, N; Singh, DAP; Sivakumar, K, et al.,; TANUVASfeeding trial was carried out for three months to assess the post-weaning growth, carcass traits and economics in Salem Black kids fed different levels of concentrate supplement (CS). Thirty-two weaned kids from a previous experiment were divided into four treatment groups namely Tt,T2, T3, and T4 (comprising four male and four females in each) at the age of three months. The kids of all groups were allowed for 6 h grazing daily. While the kids of Tt were not supplemented and served as a control, the kids of T2, T3 and T4 groups were offered CS at 1.5 2.0 and 2.5 per cent of BW, respectively. At the end of the feeding trial, four representative animals from each group were slaughtered for assessing the carcass traits. Results revealed that net BW gain and ADG were higher (P<0.01) in T3 and T4 groups as compared to the T1 group. The ADG recorded was 41.64, 46.61, 51. 47 and 58.45 g in T1, T2, T3, and T4 groups, respectively. When compared to Tt the ADG was 11.9, 23.6 and 40.4 per cent more in T2, T3 and T4 groups, respectively. Similarly, the CS-supplemented kids had better (P<0.01) carcass traits in terms of dressing percentage, loin eye area, carcass length. The weight of cut-up parts viz., leg, loin, rack were also higher (P<0.01) in CS-supplemented groups. Feeding of CS resulted in better economic returns. It is concluded that supplementation of CS at the rate of 2.5 per cent of BW during the post-weaning period improved the body weight gain, carcass traits and monetary returns in Salem Black kids.ArticleItem Open Access PRODUCTION AND REPRODUCTION OF SALEM BLACK GOATS ON CONCENTRATE SUPPLEMENTATION DURING PHYSIOLOGICAL STAGES(2021) Bharathy, N; Anandha Prakash Singh, D; Sivakumar, K, et al.,; TANUVASA study was undertaken (February to August 2019) to assess the performance of Salem Black does fed on graded levels of concentrate feed in critical physiological stages viz., prior to and after breeding (21 d each), late gestation (last 28 d) and early lactation (up to 28 d). A total of 32 does of similar body weight (29 kg) and age (2 to 5 yr) were divided into four groups with eight each. The does under T were allowed for grazing (6 h) alone, whereas the does under T , T , and T groups 1 2 3 4 were offered concentrate feed daily @ 100, 200 and 300 g, respectively, besides grazing. The body weight gain after flushing were significantly higher (p<0.01) among the supplemented groups (T , T , and T ) whereas body weight loss was observed in T group (-0.44±0.23 kg). 2 3 4 1 Similarly, the body condition score of does after flushing and steaming up were 3.13 to 4.00 in supplemented groups (T , T , and T ) and 2.63 to 3.30 in T . The number of services required per 2 3 4 1 pregnancy ranged from 1.25 (T ) to 1.88 (T ) and did not differ significantly among the groups. The 4 1 mean birth weight of kids was significantly higher (p<0.05) in T (2.3 2kg) than T (1.98 kg), T (2.11 4 1 2 kg) and T (2.22 kg). The results indicated that the supplementation of concentrate feed @ 300 g to 3 Salem Black goats improved body weight gain during flushing, pregnancy and birth weight of kids born as compared to non-supplemented group maintained on grazing only.ArticleItem Open Access PRODUCTIVE AND REPRODUCTIVE PERFORMANCE OF SALEM BLACK GOATS FED ON GRADED LEVELS OF CONCENTRATE SUPPLEMENTATION DURING DIFFERENT PHYSIOLOGICAL STAGES(2021) Bharathy, N; Anandha Prakash Singh, D; Sivakumar, K, et al.,; TANUVASAstudy was undertaken to assess the performance of Salem Black does fed on graded levels of concentrate feed in different physiological stages viz., prior to breeding (21 days), late gestation (last 4 weeks) and early lactation (up to 4 weeks). A total of 32 Salem Black does of similar body weight (30 kg) and parity (2-5) were divided into four groups of eight each. The does under Gr 1 were allowed for grazing (6 h) without concentrate, whereas the does under Gr 2, Gr 3, and Gr 4 groups were offered concentrate feed @ 100, 200 and 300g, respectively, besides grazing. The body weight gain before breeding were significantly higher (p<0.01) among the concentrate-fed groups (Gr 2, Gr 3, and Gr 4) whereas body weight loss was observed in Gr 1 (-0.44±0.23 kg). Similarly, the body condition score of does after flushing and steaming up were 3.13 to 4.00 in concentrate-fed groups (Gr 2, Gr 3, and Gr 4) and 2.63 to 3.30 in Gr 1. The number of services required per pregnancy ranged from 1.25 (Gr 4) to 1.88 (Gr 1) and did not differ significantly between the groups. Mean birth weight of kids was significantly (p<0.05) higher in Gr 4 (2.62kg) fed with 300 g concentrate than Gr 1 (1.98kg), Gr 2 (2.11kg) and Gr 3 (2.22kg). The litter size and prolificacy in terms of twins were not significantly different among groups. The result indicated that the supplementation of concentrate feed @ 300 g to Salem Black does improved the body weight gain during flushing, pregnancy and higher litter weight as compared to non-supplemented group on grazing only.
