Descripción
Genetic and phenotypic parameters of body length (Bl), heights at the withers (Hw) and at the hip (Hh), and thoracic perimeter (Tp) were estimated in 1273 adult females of the Canchim (5/8 Charolais + 3/8 Zebu) breed, using the restricted maximum likelihood method. The heritability estimates were 0.33 (Bl), 0.34 (Hw), 0.36 (Hh) and 0.19 (Tp). The genetic correlations among the body measurement traits were: 0.86 (Bl and Hw), 0.92 (Bl and Hh), 0.62 (Bl and Tp), 0.97 (Hw and Hh). 0.82 (Hw and Tp), and 0.70 (Hh and Tp). The phenotypic correlations were smaller. The results suggest that Bl, Hw and Hh can be modified by selection
