甘肃马海毛山羊新品种群育种方法的研究

通过１９９１～１９９４年用安哥拉山羊与中卫山羊进行杂交试验，在获得含安哥拉山羊不同血缘的杂种３万余只及完成９项研究的基础上，考虑到甘肃省拟发展马海毛山羊地区中近期的生态经济及生产技术条件，提出从含有安哥拉山羊血缘５／８到７／８的杂种中，选择理想型公、母羊进行横交繁育，并采取８项主要措施，到２０００年培育出甘肃马海毛山羊新品种群；同时，生产出含安哥拉山羊不同血缘的杂种羊１０万只，年产马海型羊毛５００００ｋｇ，建立马海毛生产基地，为在下世纪初培育出甘肃马海毛山羊新品种奠定良好的基础。

Breeding Technology of New Breed Herd of Gansu Mohair Goat

Based on the crossbreeding results between Angora goat and Zhongwei Goatfrom 1991 to 1994 that about 30 000 crossbreed of consan quinity of Angora goat and nine re-search subjects have been achieved and on the consideration that Gansu will develop a nearfuture ecological economics and production technological conditions for Mohair goat produc- tion area,the author proposed that new mohair breed goat will be established from the trans-verse crossing between ideal crossbred male and female which contain 5/8 to 7/8 Angora con-san guinity,eight main measures will be put into practice to achieve the goal that new breedherds will be bred before 2000 and 100 000 cross goat which contain different Angora goatconsan quinity will be produced,annual yield of 50 000 kg mohair will be produced,produc-tion base of mohair will be established and all the above results will be used as the basis fordeveloping new goat breed in the next century.
