The present study was carried out with the total of 18 Sahiwal cattle of 1st to 4th 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.
