Correlation of productivity with body composition indices of Limousine breed of young cattle
Abstract
The essential differences between the calves and heifers on the breast and pelvis indices that characterize the specialization of cattle meat production were determined. Thus on the breast and pelvis index calves surpassed significantly by 12,3 and 10 units (P<0,01) their coevals of 12 and 15 months of age, respectively. The study of the correlation showed that in 12 months of age correlation between the index stretching and body weight was slightly negative, while in the age of 15 months the index was positively correlated which indicates that the stretched animals are taller. On breast index of constitution a fairly high correlation with body weight in both 12 and 15 months of age. The correlation coefficient (0,51) between breast index in 12 months of age and body weight in 15 months of age indicates that on the value of the first one can predict the development of an animal in the future.
