dc.descriptionTropical hair sheep of the Morada Nova breed were utilized to study the effect of energy intake on age and weight at puberty. Twenty-four ewe-lambs, 140+/-1.2 days of age and weighing 12.5+/-.25Kg, were assigned to receive 50, 200, 350 or 500g of maize grain per day (T1, 2, 3 and 4, respectively) along with 150g of cottonseed cake and a ground maize stover/maize cob mixture ad libitum. Between the beginning of the experiment and first estrus, one lamb was removed from T3 and one from T4 due to rumen disorders. Also, one lamb from T1 was eliminated for reasons not related to experimental treatments. The remaining 21 lambs gained weight at rates of 42+/-6, 49+/-5, 60+/-8 and 74+/-9g.day-1 for T1, 2, 3 and 4, respectively. First estrus, detected by vasectomized teaser rams, was displayed at 283+/-13, 294+/-15, 310+/-16 and 266+/-16 days of age and 19.1+/-1.2, 20.6+/-1.2, 23.4+/-2.0 and 20.8+/-1.4Kg of weight for the four treatment groups. Treatments differences were not significant (P>.05) for age or weight at first estrus. Performance of Morada Nova ewe-lambs in this experiment indicates that postweaning feeding should provide for average daily gains within the range of 35 to 75g.day-1; that animals thus fed will display first estrus at 260-320 days of age (irrespective of weight) or at 18-22 Kg weight (irrespective of age); and that a higher energy intake level will not accelerate age of first estrus.pt_BR
