Study on association among production traits of 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. Phenotypic correlations among these traits were estimated using Snedecor and Cochran (1994). The strong positive association between milk yield and lactation traits indicates that improvement in one trait may lead to a desirable change in the other. The study suggests that selection for higher peak yield and optimum lactation length can result in enhanced total milk production.
