Factors affecting production records of lambs from a flock of East African Blackhead sheep
Dorset Horn rams were used on East African Blackhead sheep in western Uganda in mutton production through improved lamb growth. The crossbred lambs were significantly heavier than the indigenous at birth. From birth to weaning at five months, the growth rates of both types were identical, being 0...
