N.  aEffect of premating injections of insulin on fertility and prolificacy of ewes.  c1991  aNinety-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 &lt 0.05) in insulin-treated ewes (P &lt 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).  aInsulin  aReproductive performance  aSheep  aEficiência reprodutiva  aFertilidade  aInsulina  aOvelha  aOvino  aCrescimento folicular  aFertility  aFollicular growth  aProlificacy  aProlificidade1 aTHACKER, P.
