摘要: 我国肉牛业目前面临的主要问题是商品牛源紧张、牛肉供应不足。基础母牛繁殖率低是造成牛源紧张的重要因素。因此,提高母牛繁殖率对于缓解牛源紧张、提高养殖效益、促进产业健康发展具有重要意义。试验通过在短期内补饲催情饲料结合药物诱导催情的方法,来提高母牛繁殖率。结果表明。饲料催情结合药物催情2个月内母牛发情率达到81.8%,妊娠率为63.6%;发情率和妊娠率均有明显提高。对比目前生产模式,该技术方案使用效果比较明显,可以显著提高肉牛养殖的经济效益。

Abstract: The major problem for beef cattle industry in our country is currently facing with tension of commercial cattle sources and insufficiency of beef supply. Low reproductive rate of basic cows is an important factor causing tension of cattle sources. Therefore, improving cow reproductive rate is of great significance to alleviating tension of cattle sources, improving farming income and promoting healthy development of the industry. In this experiment, the combination of short-term aphrodisiac fodder and aphrodisiac drug was used to improve cow reproductive rate. The results showed that aphrodisiac fodder combined with aphrodisiac drug made cow estrus rate reach 81.8% and percent pregnancy rate reach 63.6% within two months. Estrus and pregnancy rates were improved significantly. Compared with the present mode of production, the technology solution has obvious effects and can significantly improve the breedin~ economic benefits.
