Prediction of carcass traits in fattening Friesian crossbred and buffalo male calves by using body measurements

الملخص EN

Five body measurements were taken on 142 Friesian crossbred and 49 buffalo male calves.14 Friesian crossbred and 12 buffalo male calves slaughtered at 435+17.5 kg average body weight and at about 15-17 months of age.

the aims of the present study were to estimate the relationship between body measurements and slaughter weight, and carcass characteristics.

body measurements were used to predict carcass traits.

the slaughter weight was positively and significantly correlated with most of carcass traits in range from0.15 to 0.98 and 0.13 to 0.89 for both Friesian crossbred and buffalo carcasses, respectively.

both of slaughter weight and heart girth showed high accuracy ranged from 0.33 to 0.97.

round circumference (RC) and body length (bl) had highly accuracy for predicting most of carcass traits in both Friesian crossbred and buffalo carcass traits with values of 0.89 to 0.99, respectively.

the present results concluded that, the heart girth (HG) of Frisian crossbred calves and each of round circumference (RC) and body length (BL) of buffalo calves were the best indicators to predict most of their carcass traits.
