Abstract: Three groups of about 65 seasonally anovular Corriedale ewes were penned and exposed to rams on November 4, 1989. A fourth group (n=64) was maintained in a 3-ha paddock and also exposed to rams on the same date. The sexual behaviour exhibited by rams in contact with penned ewes was recorded during nine simultaneous observation sessions lasting 2 h each. Five days after ram introduction, incidence of ovulation and ovulation rate were higher (P < 0.01) in adult than in 1.5-year-old ewes. Among penned adult ewes, a greater (P < 0.05) incidence of ovulation was recorded in ewes maintained in contact with rams and oestrous ewes (95.8%) than in ewes exposed to either rams with or without recent experience with oestrous ewes (68.7 and 57.1%, respectively). The fourth group, exposed to rams in field conditions, exhibited a lower (P < 0.05) incidence of ovulation (31.9%) than any other group. No differences among treatments were detected in 1.5-year-old ewes. The incidence of ovulation was associated (r=0.99, P<0.05) with the sexual behaviour displayed by the rams. It was concluded that the sexual behaviour of the rams plays an important role in ram-induced ovulation and that the continuous presence of oestrous ewes is necessary for the maximum efficacy of the technique in Corriedale ewes. |
