摘要： The aim of the present study was to determine the effect of insemination of Italian Mediterranean buffalo by artificial insemination in China. The frozen semen of Italian Mediterranean buffalo imported to China was used to inseminate the existing Murrah, Nili-Ravi and local buffalo from Guangxi Buffalo Research Institute. During 3 years, 65 Murrah buffaloes, 48 Nili-Ravi buffaloes and 52 local buffaloes their ages range between 2.5 and 9 years old with natural estrus were selected and inseminated with the Italian Mediterranean buffalo frozen semen in the uterine horn by the rectum deep grasp. 40 days after mating, the early pregnancy diagnosis of these inseminated animals was checked by B Mode ultrasound. The results showed that the conception rate in cow of Murrah, Nili-Ravi and local buffalo were 45.31%, 52.08%, 48.08%, respectively. And the average conception rate was 47.88%. Although there was no significant difference (P>0.05) among the different buffalo species. The results suggested that it was practicable that the introduction of Mediterranean water buffalo frozen semen to carry out hybrid combinations, to improve the existing water buffalo species and to improve their production performance.
