Abstract

The experiment has two objectives, to evaluate the responses to selection fnr increased body weight under pasture conditions, and to compare two selec n " Previous work in New Zealand (Carter, 1971) has established that worthwhile selection responses are possible under pasture conditions, selecting for 5-month weaning weight or yearling weight. However, the cooperative nature of that trial precluded the establishment of a control herd, and thus the estimation of correlated responses to selection may be difficult.
The purpose of this paper is to report preliminary estimates of the correlated changes in cow weight and reproduction, in response to body weight 
selection.
