[Objective]In order to solve the problems on heterosis decreasing and no mating breed in beef cattle production. [Method]Comparative test was carried on importing hybrid by introducing frozen semen of Fleckvieh,which was an dairy and beef type cattle. [Result]The body weight and size from first- filial generation of new born, 3 months had no significant difference than that of the control. At six months, between the experimental and control group, there was significant difference on chest measurement and body weight. And at 12 months, they also had obvious difference on body height, body slanting length and chest measurement. The above results indicated that the experimental group developed faster than the control before 12 months old. [Conclusion]The hybrids was good in adaptability, disease resistance, crude feed tolerance,growth and development by introducing German dualpurpose Simmental cattle, which got high praise in the local and had good prospect in extension.
