[目的]为探索弗莱维赫牛冻精三元杂交模式研究。我市引进弗莱维赫世界著名乳肉兼用新品种牛细管冻精,对西本F1代杂种母牛,进行三元杂交改良试验,以期为弗莱维赫牛杂交改良利用和提高肉牛的生产性能,提供科学依据。[方法]在相同饲养管理条件下,测定并对比弗♂×（西♂×本♀）三元杂交牛和（西♂×本♀）二元杂交牛和本地黄牛的初生、3月龄、12月龄、24月龄的生长发育指标。[结果]表明：弗莱维赫三元杂交牛各月龄体重明显高于本地牛和西♂×本♀牛,12月年公母体重达355.3±35.3kg、359.4±39.3kg,比西♂×本♀二元杂交公母牛242.6±51.2kg、237.3±44.3kg,分别提高了46.69%和51.15%。体尺变化12月龄弗♂×（西♂×本♀）一代公牛的体高、体斜长、胸围、管围分别比西♂×本♀牛一代公牛提高16.7%、14.8%、16.2%和20.7%。[结论]以上结果表明弗西本元杂交牛各项生长发育指标均高于西本牛和本地黄牛,改良效果非常明显。

[Objective]To explore Northro bule frozen semen of world famous northrop der to improve the beef cattle production perf p Frye cattle frozen ternary hybrids model research. The frye cattle was introduced to crossbreed XiBen FI cows in ormance and provide scientific basis for further study. [Meth ods]Under the same breeding management conditions, the growth and development indexes were measured and compared of the northrop frye ♂ (Simmental ♂× Local×) ternary hybrid cows and (Simmental ♂ ×Local ♀) binary catalo and local cattle's born, 3 months, 12 months, 24 months. [Result]The results showed that month-weight of Northrop Frye ternary hybrids cattle was obviously higher than that of local cattle and west♂×♀. The 12-month body weight of male and female was 355.3 ± 35.3 kg, 359.4 ±39. 3 kg, more than that of Simmental ♂× Local ♀ two hybrid male cow, which was 242.6 ± 51.2 kg, 237. 3 ±44.3 kg, increased by 46.69% and 51.15%, respectively. Body size had been changed, body height, body inclined length, chest circumference, circumference of cannon bone of Northrop Frye ♂× (west ♂) local♀ ) generation bulls were higher than those in (Simmental ♂× Local ♀ ) the cattle generation bull, and increased by 16.7%,14.8%,16.2% and 20.7%. development indexes of Northrop Frye cattle were hi effect was very obvious. [Conclusion]The result indicated that the growth and gher than of XiBen and local cattle. And the improved
