  • A backcross program of the Ideal breed (I) to Texel (T) was carried out. Postweaning growth of lambs of both sexes of genotype T: (3/4T-1/4I) and I was evaluated during two months under two environmental conditions:TCO, feed lot experiment and TCA, range conditions. All lambs were weighed weekly. Those in feed lot were fed daily a ration of hay with commercial pellet. The relative ADG was evaluated as ADG/mean weight. Neither final weight nor growth rate gave significant differences between genotypes within environment but differences were significative for each genotype through out the two environmental conditions (P
