The result of an intensive 15 months study of 10 flocks of indigenous sheep is recorded. Lambing rates approach 1.5 lambs per ewe per year, but a death rate of 23 percent and on off take of 27 per cent, means that flock numbers are probably slightly declining. Twins account for 14 per cent of all...
