Abstract

The objective of study was to know the change in BCS at different stages and effect of BCS at stage II (post-partum) on 90 day lactation yield, peak yield, day to attain peak yield, post partum interval to estrus (PPIE) and calf birth weight in Tharparkar cattle. Overall mean values for BCS during stages I to VIII were 4.17 ± 0.11, 4.00 ± 0.11, 3.90 ± 0.07, 3.73 ± 0.08, 3.57 ± 0.06, 3.57 ± 0.07, 3.70 ± 0.06 and 3.85 ± 0.06 respectively. The 90 days milk yield was non-significant among three groups. There is a significant difference between groups for peak yield. The cows with BCS values ≥ 4 expressed highest peak yields (6.06 ± 0.90 kg). Significant differences (p ≤ 0.01) between group 1, 2 and 3 were also found for days to attain peak yield and postpartum interval to estrus. Cows with less than 3.5 BCS had highest postpartum interval to estrus (53.50 ± 18.57 d) but differs non-significantly from other groups. Significant differences (p ≤ 0.05) existed among calf birth weights for these groups. In Tharparkar cattle, BCS 3.5 to 4.0 is better for fetus growth. Higher milk yield, peak yield, and day to attain peak, while lower post partum interval to estrus (PPIE) were supported by more than 4 BCS in Tharparkar cattle. These findings suggest that BCS adjustment at post partum period may beneficial for production and reproduction point of view.
