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.EnglishVeterinary ScienceArticle
