Effect of different levels of concentrate mixture feeding on milk yield, post partum Estrus and lactation length in Sirohi Goats

Abstract

Twenty four lactating Sirohi goats averaged 36.2±0.70 kg body weight were used in a comparative feeding trial to investigate the effect of different levels of concentrate mixture feeding on milk yield, post partum estrus and lactation length in Sirohi goats during November, 2016 to May, 2017. The total duration of feeding experiment was 90 days, however, daily milk yield was measured at 15 days intervals beginning on post-partum day 15 (i.e., on days 15, 30, 45, 60, 75, and 90) by hand milking and lactation length was also recorded to see the total lactation period in Sirohi goat. Post partum estrus was detected by visual observation. The animals were divided randomly into four equal (n=6) groups. Apart from daily grazing, concentrate mixture feeding were given to Sirohi goats in ratio of @ 0.00 gm (T1), 100gm (T2), 200gm (T3) and 300gm (T4) respectively with Prosopis cineraria dry leaves (Khejri) ad libitum. The results revealed that the Sirohi goats showed significantly (P
