摘  要：
通过边来×藏羊、夏洛来×藏羊、边来×细杂三个杂交组合试验组和藏羊、茨杂、细杂三个对照组的系统试验研究,表明边区来斯特为生产肥羔的理想父本,边来×藏羊为高寒牧区生产肥羔的最佳杂交组合;边藏F_1不仅在草原纯放牧条件下增重快,达到当年肥育当年屠宰的效果,而且是适应性好、体格大、生长快的优质易地肥育羊源;边细杂后代同样具有生长优势;茨杂羔可以用于肥羔生产;夏藏杂交组合不适于高寒牧区生产肥羔。依靠经济杂交手段可使羊肉生产效益提高40～70％。目前条件下,农区宜于以易地肥育为中心,适当引进肉用品种父本杂交生产肥羔。

摘  要：
There wete three hybridized combinations,i.e.,Border leicester×Tibetan sheep(B×T),Charollais×T(C×T) and B×Hybrid of Fine wool sheep(B×H),and three control groups,i.e.,T.Tsigai's hybrid (containing over 50％ Tsigai's blood,TH)and H.It was demonstrated that B was an excellent crossing sire, B×T was the finest hybridized combination for producing fat lamb in alpine cold pastural region.The F_1 lamb of B×T not only grew quickly in graze fattening, but also could be transferred from pasture to farmland region for fattening.The F_1 lamb of B×H had better heterosis in growth,the lamb of TH might be better fattening lamb,and C×T was not suitable to local conditions for producing fat lamb.Through economic crossing,mutton benefit increased by 40～70％.It is concluded that the programme of transferring fattening lamb is advantageous to mutton production in fatmland region in cutrent situation.
