[目的]研究弗杂牛在当地的生长及肉用性能。[方法]随机选择弗莱维赫牛与遵义本地黄牛的杂交F1代（弗×本）、弗莱维赫牛与（西门塔尔×本地黄牛）三元杂交一代F1（弗×西本）牛,作试验组,本地纯种黄牛（对照组）各30头,进行饲养和育肥试验。[结果]表明：6月龄时试验组弗×本、弗×西本的体重分别为90.00 kg、118.18 kg,比对照组本地黄牛71.87 kg分别提高了25.2%、64.43%,差异均极显著（P〈0.01）。体高、胸围分别提高了29.67%、21.63%和30.59%、19.83%,差异均极显著（P〈0.01）。经育肥,对2头18月龄的弗×西本和弗×本进行屠宰测定,其屠宰率分别为58.12%、53.71%,净肉率分别为45.67%、38.90%,与同龄的本地黄牛（2头）相比,屠宰率分别高了10.2%、5.61%,净肉率分别高了6.95%、0.18%。[结论]用弗莱维赫牛改良遵义本地黄牛,其后代的体尺、体重和屠宰性能等方面都到了改善和提高,效果较明显。
[目的]研究弗雜牛在噹地的生長及肉用性能。[方法]隨機選擇弗萊維赫牛與遵義本地黃牛的雜交F1代（弗×本）、弗萊維赫牛與（西門塔爾×本地黃牛）三元雜交一代F1（弗×西本）牛,作試驗組,本地純種黃牛（對照組）各30頭,進行飼養和育肥試驗。[結果]錶明：6月齡時試驗組弗×本、弗×西本的體重分彆為90.00 kg、118.18 kg,比對照組本地黃牛71.87 kg分彆提高瞭25.2%、64.43%,差異均極顯著（P〈0.01）。體高、胸圍分彆提高瞭29.67%、21.63%和30.59%、19.83%,差異均極顯著（P〈0.01）。經育肥,對2頭18月齡的弗×西本和弗×本進行屠宰測定,其屠宰率分彆為58.12%、53.71%,淨肉率分彆為45.67%、38.90%,與同齡的本地黃牛（2頭）相比,屠宰率分彆高瞭10.2%、5.61%,淨肉率分彆高瞭6.95%、0.18%。[結論]用弗萊維赫牛改良遵義本地黃牛,其後代的體呎、體重和屠宰性能等方麵都到瞭改善和提高,效果較明顯。

【Objective】To study the growth and beef performance of Fleckvieh crossbreed in Zunyi.【Method】Thirty crossbreeds,the F1 of Fleckvieh and Zunyi indigenous yellow cattle and hybrids of Fleckvieh and Simmental crossed with indigenous yellow cattle,were randomly selected as the test group,and 30 local purebred cattle were as the control to feed and carry out fattening experiment.【Result】The results showed that the body weight of the crossbreed of Fleckvieh and local cattle,Fleckvieh,Simmental and local cattle was 90.00 kg and 118.18 kg at six months old,while that of local cattle was 71.87 kg.Compared with the control,it increased 25.2% and 64.43%.The body height and chest circumstance increased 29.67%,21.63% and 30.59%、19.83%,respectively.The difference was significant（P0.01）.After fattening,two eighteen-month old hybrids were slaughtered from Fleckvieh and local cattle,Fleckvieh,Simmental and local cattle.The slaughter rate and net meat percentage was 58.12%,53.71% and 45.67%,38.90%.Compared with the same age local cattle,the slaughter rate and net meat percentage improved 10.2%,5.61% and 6.95%,0.18%,respectively.【Conclusion】The body size,body weight and slaughter performance of the offspring increased and improved,the improvement effect was significant.
