Abstract

The present study was carried out with the total of 18 Sahiwal cattle of 1^st to 4^th parity were selected for the study and distributed into three different groups based on their pre calving BCS (before 15 days of predicated date of calving) namely G1 (2.50 - 3.00), G2 (3.25 - 3.75) and G3 (4.00 and above) with six animals in each group. Highest average fortnightly fat percent in the milk was observed in group G3 (3.95±0.03%) followed by group G2 (3.90±0.02%) and G1 (3.63±0.02%). The highest average protein per cent 3.61±0.01 was observed in G3 group followed by 3.33±0.01% and 3.18±0.004%, respectively in G2 and G1 group. The highest average lactose per cent 4.41±0.02 was observed in G3 group followed by in G2 and G1 group 4.28±0.10 and 4.20±0.012, respectively. The highest average total solid per cent 12.67±0.03 was observed in G3 group animals followed by in G2 and G1 group with 12.57±0.02 % and 12.26±0.02 %, respectively. The Sahiwal cattle of G2 group had shorter post-partum estrus period, fewer services per conception, higher first service conception rate and shorter service period and the values for corresponding parameter were 63.67±1.17 days, 1.34±0.21, 66.67 per cent and 89.84±3.79 days, respectively. The study revealed that BCS had significant (P<0.05) effect on fat, SNF, lactose, protein, total solid percent, post-partum estrus and service period under the study.
