Abstract:
The present study to find out the effects of supplementation of the area-specific mineral mixture on productive and reproductive performances of crossbred cows during pregnancy to lactational transition phases including the birth weight of calf, first postpartum estrus, conception rates, milk yield, and milk composition. For these purposes, 18 pregnant crossbred cows were selected and divided into two groups viz., Control-T0 (N=9) and Treatment-T1 (N=9) supplemented with 0 and 30 g ASMM/animal/day starting from 3 months prior to the expected date of parturition to till first post-partum oestrus, respectively. Milk samples were taken fortnightly. Overall mean birth weight of calf born in T0 and T1 group was 20.14 ± 1.70 and 19.56 ± 1.09, respectively and there was non-significant (P>0.05) difference between the two groups. The onset of first post-partum heat was 108.13 ± 16.23 days and 92.29 ± 9.95 days respectively. Conception rate post-partum heat was 22.22% and 77.78% respectively. The overall mean of total fat % in T0 and T1, was 4.01 ± 0.20 and 5.40 ± 0.22, total solid % was 13.03 ± 0.31 and 14.72 ± 0.37 %, solid not fat 9.02 ± 0.14% and 9.22 ± 0.31% and total ash was 0.62 ± 0.03% and 0.65 ± 0.02%, crude protein was 3.35 ± 0.10% and 3.63 ± 0.14%, respectively and was statistically non-significant (P>0.05) among the groups. Overall Milk yield was 9.42 ± 0.54 and 10.76 ± 0.37 kg/days, respectively, and was statistically significant (P < 0.001). This study indicated that dietary supplementation of the area-specific mineral mixture in the crossbred cattle, improved the productive and reproductive performances during last trimester to first post-partum oestrus.
