Lactation performance of Sirohi goats under intensive production system.

Factors affecting the lactation traits of Sirohi goats reared under intensive system of management at CIRG, Makhdoom were studied from 1998–2001. The average total lactation yield was found to be 117.66 l in a lactation length of 186.1 days. Sirohi goats produced an average milk yield of 627.7 ml/day. The 90 and 140 days milk yield and the daily milk yield significantly varied (P<0.01) between years and parities. The total lactation yield increased over the parities and reached its peak in the third parity. All the lactation traits studied were non-significantly higher in does kidded during September-December season. The daily milk yield was significantly higher (P<0.05) in does with multiple births compared to does with single birth.
