Conteúdo: 	Abstract: Initiation of puberty in terms of separation of prepuce from penis was earlier in indigenous lambs than in exotic breeds and their crosses. Influence of body weight and testes dimension was more pronounced on puberty than age and testes dimension as well as age and body weight. Half-bred lambs exhibited sexual activity earlier at lower body weight than indigenous lambs. Delayed sexual activity was observed in exotic and higher crosses (RM 3/4). Puberty appeared at 240 days and 27.6 kg body wt in half-breds. Performance of exotic and indigenous breeds was relatively poorer than of half-breds. A good percentage (40-60) of rams ejaculated semen of optimum quality required for breeding purposes at 12-14 mo. of age.
