Abstract

The data of 22,630 fortnightly test day milk yield of 2,263 Sirohi does at different lactations were used and subjected to least square analysis to study the effect of various non-genetic factors like cluster, periods of kidding, season of kidding, parity, type of birth and regression of dam’s weight. The overall least-squares means of different individual fortnightly test day milk yields increase from 0.820±0.04 kg on TD1 (15th day of lactation) to a peak yield of 1.070±0.06 kg on TD2 (30th day of lactation) and subsequently declined to 0.348±0.01 kg on TD10 (150th day of lactation). Cluster and period wise variation were highly significant on all stages of fortnightly test day milk yields. The significantly higher test day milk yield were observed in winter kidded does as compared to summer and rainy kidded, it could be milk climatic conditions. The parity had statistically highly significant effect on fortnightly test day milk yields, in which seemed that milk yields increase as parity increase, thereafter declined slowly. The effect of type of kidding was non-significant on overall fortnightly test day milk yield under this study. The regression of dam’s weight at kidding was positive and highly significant (P≤ 0.01) on all fortnightly test day milk yield. In order to increase goat milk production, goat keepers need to be focused on nutritional and others environmental conditions as it affect their flock.
