| 摘 要： | 应用AI ET法分别对三组试验牛进行处理,人工诱导生产肉牛双胎,双胎率达60.8%(79/130),产犊率147.7%(192/130)。其中试验组2(自然发情后AI ET)双胎率达66%(33/50),产犊率150%(45/30),显著提高了母牛的繁殖率。

| Abstract: | Three sets experiment cattles were be managed with the AI and ET method to induce twining of meat cattle,twining rate being 60.8%(79/130),produce calf rate being 147.1%(192/130).Among them experiment a set 2(naturalness oestrus AI and ET),twining rate being 66%(33/50),produce calf rate being 150%(45/30).The reproduce rate of cattle was improved notability. |
