Abstract

In the present work, we developed several extensive experiments with Pollwart (€œIdeal€™) and Corriedale sheep flocks, at the Posto de Ovinos e Caprinos de Itapetininga, Instituto de Zootecnia, Secretaria da Agricultura do Estado de São Paulo, with the aim of investigating the effects of flushing on the twinning rate. The frequency of twin births is very low under natural conditions but the flushing of ewes of both races increased the twinning rate up to levels of 20-30%. The overall frequency of monozygotic twins among twin lambs was negligible (less than 1%).
