[目的]本文对早胜牛（对照组）和红早F1代（试验组）强度育肥，研究早胜牛与红安格斯杂交肉牛早起强度育肥肉用性能。[方法]选择了早胜牛50头，红早F1代96头，阉牛52头，母牛44头，经过112d育肥。[结果]表明红早F1代平均日增重897．95g，当地早胜牛平均日增重686．55g，提高30．79％，增重效果明显，差异显著（P〈0．05），屠宰试验结果表明试验组和对照组的屠宰率分别为52．10％和56．03％，净肉率为41．17％和45．21％，差异显著（P〈0．05），高档肉占净肉分别为7．72％和10．11％，差异显著（P〈0．05）。[结论]试验证明，利用红安格斯肉牛杂交改良早胜牛，可显著提高早胜牛肉用生产性能。

[Objective]Fattening performance of different F1 crossbreeds from red Angus and Zaosheng cattle,was studied by intensive fattening in early stage. [Method]96 F1 hybrids of red Angus and Zaosheng cattle, 50 Zaosheng cattle, 52 castrated cattle and 44 female cattle were selected for fattening. [Result]After 112 days, the average daily gains of control groups was 686.55g, while the test group was 897.95 g , which was 30.79% higher than that of the control group, respectively. The result of slaughtering test indicated that the dressing percentage and net meat rate of test group were 56.03% and 45.21%, those of the control group were 52.10% and 41.17%, the difference was significant （ P 〈0.05）. The high-grade beef percentage of test group was 10.11%, the control group was 7.72% and the difference was also significant （ P 〈0. 05）. [Conclusion]It was shown that beef performance of Zaosheng cattle was remarkably improved by crossbreeding with red Angus.
