摘要
引进新美系纯种杜洛克、大白、长白种猪,并在粤北地区进行饲养,测定新美系纯种一代、杂交二代(长大杂)的生长、繁殖性能及杂交三代(杜长大杂)生长性能,比较分析不同气候环境条件下新美系种猪的适应性.结果表明新美系种猪在粤北地区适应性能较强,生长、繁殖性能优越,可进行推广养殖.
The experiment was carried out on newly imported Duroc(D), Yorkshire (Y) and Landrace(L) from U.S.A raised in the northern Guangdong. The growth capability and reproduction performance were determined by purebred of the Duroc(D), Yorkshire(Y), Landrace(L) and the second generation crossbred pigs (L♂×Y♀). The growth capability were determined by the third generation crossbred pigs (D♂×LY♀). Comparison and analysis of adaptability of new American Line pig under different climatic conditions. The results shows that new American breeding pig had strong adaptability, superior growth capability and reproduction performance in northern Guangdong.
