Abstract
The relationship between heart girth and live weight was analysed with respect to effects of breed and plane of nutrition in dual purpose heifers using data from three experiments. A simple empirical equation for estimation of live weight by heart girth was established. In an experiment with two breeds (Red Danish and Danish Black and White) and three planes of nutrition significant breed differences in the parameter estimates were found. In Red Danish it was found in two experiments that increased plane of nutrition decreased live weight at a certain heart girth. Danish Black and White showed no effect of plane of nutrition on the relationship between heart girth and live weight. The established estimation of live weight by heart girth were found to fit satisfactory for Danish Black and White heifers with a daily gain in the range of 400 to 800 g, and for Red Danish in the range of 600 to 800 g.Keywords
