摘要：

Ninety-six Suffolk ewes received daily injections of either long-acting insulin (1.0 IU kg-1) or saline for 3 consecutive days after introduction of rams. Basal serum LH concentrations were higher (P < 0.05) in insulin-treated ewes (P < 0.05) but concentrations of estradiol-17B and the magnitude of the preovulatory LH surge were unaffected. Interval to breeding, pregnancy rate and subsequent litter size were not influenced by treatment (66.6 vs. 63.3 h, 69 vs. 74% and 1.65 vs. 1.69 for insulin and saline-injected ewes, respectively).
