Abstract
An investigation was undertaken to study the biometrics of udder and certain body parts in Jersey x Kankrej (F1 and F2) crossbreds. The JKF1 animals showed consistently and significantly higher body weight than JKF2 animals. The linear measurements viz. Body length, wither height, heart girth and paunch girth also showed similar trend as that of body weight. The different body measurements showed positive and highly significant association with body weight. For estimation of body weight he prediction equations based on heart girth and body length together gave quite high R2 values in all the age groups. Even heart girth alone was found to be enough to give the reliable estimate of the body weight. Hence, the prediction equations for different age groups have been recommended for estimating body weight of Jersey x Kankrej at different age groups.
