PRODUCTION PERFORMANCE OF PHULE TRIVENI COWS

Abstract

The data on production performance of 1398 records of Phule Triveni cows maintained at Research Cum Development Project on Cattle, Rahuri were utilized for study. The least squares means of lactation milk yield (LMY), 300 days milk yield (300DMY), lactation length (LL) and dry period (DP) were worked out. The overall mean LMY, 300DMY, LL and DP in Phule Triveni were 3112.15 ± 25.79 kg, 2883.69 ± 20.48 kg, 336.47 ± 1.74 days and 82.34 ± 2.16 days respectively. The period of calving had significant (P<0.01) effect on all the traits under study. The season of calving had non-significant influence on all the traits. The lactation order had significant (P<0.01) influence on LMY and 300 DMY. The phenotypic and genetic correlations of LMY with 300DMY and LL and between 300DMY and LL were positive and significant.
