Present investigation was carried out to study the morphometry in relation to body weight, sex and season in Vrindavani calves. All Vrindavani calves (Age 0 to 3 month) born between August 2019 to January 2020 were selected (N=87). Body morphometry comprising of Height at Withers (HAW), Height at Hip bone (HAHB), Height at Pin bone (HAPB), Rump length (RL), Ischial Width at Rump (ILWR), Medial Width at Rump (MDR), Ilial Width at Rump (ILWR), Total length (TL), Body length (BL), Hearth Girth (HG), Fore cannon bone Girth (FCBG), Face length (FL), Face width (FW), Ear length (EL) were measured at one month of age. The birth weight, weights after 15 days interval were measured till 3 months of age. we observed that most of the measurements with the exception of Heart Girth, body length, Ischial width at Rump, Face width and Ear length were significantly (p<0.001) correlated to season of birth. The morphometric measurements are also positively correlated (p<0.001) to sex of the calves. Body weights were significantly(p<0.001) correlated to Body Length and Heart Girth. Most of the Morphometric measurements and Body weights were found to be significantly (p<0.001) correlated among themselves. Heart Girth (HG, r2 =0.80) and Body Length (BL, r2 =0.71) has significant (p<0.001) effect on Birth Weight, Weight at 15 days and 30 days of age. Body Length significantly (p<0.05) effects Body weight at 45 days while only Heart Girth (HG) was found to be significantly (p<0.05) effecting body weight at 75 days of age.
