| 摘要 | [Objective] The paper was to improve the quality and growth rate of native yellow cattle in Wenzhou. [Method] Three groups of cattle were subjected to artificial insemination using frozen semen from Wagyu bull. The groups consisted of 20 native yellow cattle, 20 Angus cattle, and 20 Luxi yellow cattle. The heifers were subsequently evaluated for body size and body weight, and underwent treatment with estrus synchronization, artificial insemination, and early pregnancy diagnosis. [Result] The mean body size and body weight of native yellow cattle were found to be significantly lower than those of Angus cattle and Luxi yellow cattle (P<0.05). The estrus synchronization rate and mating rate of native yellow cattle were both 100%, while the corresponding rates for Angus cattle and Luxi yellow cattle were 90% and 95%, respectively. The ultrasound examination conducted on the 32nd day following the mating revealed a distinct image of gestation sac, which, when considered alongside the findings of the rectal examination, may be indicative of pregnancy. The conception rates were 75%, 72%, and 74% for native yellow cattle, Angus cattle, and Luxi yellow cattle, respectively. [Conclusion] The reproductive performance of native beef cattle is relatively superior. |
