ABSTRACT

The objective of this paper was to study the milk yield/adjusted chest girth ratio, taking as an indirect measure of dairy productive efficiency, in order to include this as selection criterion in Holstein breeding programs. The additive variance and covariance component was estimated with Restricted Maximum Likelihood (REML) solutions extended to 305 days milk yield (PL), extended to 305 days and mature equivalent milk yield (PEM), constant chest girth at calving (PTA), PL/PTA ratio (ELAAJ) and PEM/PTA ratio (ELAEM). The heritability (± standard error) estimated of PEM was 0.27 ± 0.11; PL, 0.19 ± 0.10; ELAAJ, 0.28 ± 0.11; ELAEM, 0.64 ± 0.14; and PTA, 0.25 ± 0.11. Phenotypic and genetic correlations between these traits were estimated, and the most remarkable were ELAAJ with PTA (-0.11 ± 0.035 and -0.50 ± 0.029), with PL (0.96 ± 0.035 and 0.67 ± 0.196) and with PEM (0.94 ± 0.036 and 0.86 ± 0.100), and PTA with PL (0.17 ± 0.035 and 0.27 ± 0.397). A lower PTA value was found when selecting ELAAJ criterion in first calving cows, equivalent to a reduction in at least 20 kg of body weight at calving (P ‹ 0.05). Finally, because ELAAJ is an indirect measure of efficiency and simple and easy to get, it is concluded that its inclusion in Holstein Friesian breeding programs has theoretical advantages in the efficiency which could have favorable repercussions in the dairy farmers economy.
