[Method]Through introduction of Australian Merino sheep for hybridizing with Gansu alpine fine wool sheep,the improvement effect of offspring was observed. [Result]The introduced Australian Merino sheep had good adaptability in the alpine pastoral areas with good hair quality,strong cold resistance and disease resistance,and they could grow and reproduce healthily in the alpine pastoral areas. The application effect of the ram was outstanding,showing large breeding amount,high conception rate and survival rate.[Conclusion]The improvement effect of offspring of Australian Merino sheep and Gansu alpine fine wool sheep was significant,and the growth performance was improved greatly.展开更多
