Effect of Non-Genetic Factors on Production Traits in Gir Cattle

Abstract

The data on production performance of Gir maintained at “Shree Nashik Panchavati Panjarpole, Nashik (M.S) were utilized for present study. The least squares means of total lactational milk yield (kg), lactation length (days), dry period (days) and peak milk yield (kg) were estimated by considering the effects of period of calving, season of calving and lactation order as non-genetic factors. The overall least squares mean for total lactational milk yield, lactation length, dry period and PMY in Gir cattle were 1887.38 ± 16.68 kg, 266.14 ± 1.38 days, 108.15 ± 1.25 days and 9.14 ± 0.12 kg, respectively. The effect of period of calving was significant on all traits TLMY, LL, DP, PMY; the effect of season of calving was significant on TLMY, LL and DP, while it was non-significant on trait PMY; the effect of order of lactation was significant on traits LL, PMY and DP while it was non-significant on trait TLMY.9.
