Karakul ram lambs were divided into 3 groups after weaning and treated as follows: group A, total isolation from ewes; group B, contact with ewes until 9 mth of age and then isolated; group C, isolated from ewes until 9 mth of age and then allowed contact. At 18 mth of age the rams were penned and then tested in pairs on oestrous ewes to establish a rank order for libido.
