Sixty crossbred cows from three different genetic groups (1/2 Holstein Friesian (F) × ½ Hariana (H), 1/2F ×1/4 Brown Swiss × 1/4 H), (1/2F×1/4 Jersey × 1/4 H) were randomly selected to study body condition score after calving and its association with performance traits. The correlations between body condition score and body weight at different stages of lactation were positively significant. The correlations between body condition score and peak yield were negative and significant at 42nd (−0.316) and 56th (−0.404) day of lactation. The effect of body condition score on other performance traits was found to be non- significant. It is concluded that high producing cows mobilize greater amount of body condition score than the low producing cows in early lactation.
