Crossbreeding of four Iranian fat-tailed sheep breeds, namely Kurdi (K), Chaal (C), Afshari (A) and Sanjabi (S) was carried out to determine the ram breed effects on productivity of Kurdi fat-tailed ewes (K) under extensive production system. A total of 475 Kurdi ewes were mated to 24 rams from the above four breeds resulting in 454 lambs. Ram breed had a significant influence on early growth traits of the lambs. Lambs sired by C rams were heavier than the other lambs (P< 0.05) at birth and… CONTINUE READING
