Abstract

In the present work, we developed several extensive experiments with Pollwart (Ideal) and Corriedale sheep flocks, at the Posto de Ovinos e Caprinos de Itapetininga, Instituto de Zootecnia, Secretaria da Agricultura do Estado de Sao Paulo, with the aim of investigating the effects of the preweaning mortality and the birth and weaning weight for twin and single lambs. The preweaning mortality among twin lambs was higher than that observed among single lambs. The weights at birth and at weaning were significantly higher for single than for twin lambs in both races.
