摘要
用ＳＭＢ、氯前列烯醇和三合激素处理１３８头产后乏情母牛，以期诱导发情。结果表明，ＳＭＢ及其辅助激素处理比未处理对照组能极显著（Ｐ＜００１）地提高发情率。处理后６，２１，４５ｄ内的发情率分别为７４５％、８０４％和８４３％；但处理后６ｄ内的受胎率为２３７％，显著低于对照组（Ｐ＜００５）。增加的激素处理比ＳＭＢ处理并没有显著提高发情和受胎效果（Ｐ＞００５），但三合激素处理有提高同期受胎率的趋势。ＳＭＢ及辅助激素处理比未处理对照组能极显著（Ｐ＜００１）提高处理后６ｄ内、２１ｄ内繁殖率，显著（Ｐ＜００５）提高处理后４５ｄ内繁殖率，相应的繁殖率分别为１７６％、４７１％和６４７％。
The results showed that SMB and the additional hormone treatment signifcantly increased(P<0.01) in estrus within 6,21 and 45 days after implant removal than control. Cumulative estrous response was 74.5%, 80.4% and 84.3%, respectively. but concepion rate in 6 days 23.7%) was lower than control (P<0.05), The additional hormone did not cause marked effect on estrus and conception (P<0.05) than SMB, but the 3 hormone mixture had a tend to increase the synchronization conception rate. In conclusion, reproduction rate was higher within 6, 21 and 45 days after treatment than control (P<0.05), cumulative reproduction rate was 17.6%, 47 1% and 64.7%, respectively.
