摘要
大凉山黑猪生长速度慢,用杜洛克、巴克夏等优质公猪杂交改良后,育肥性能有了明显提高。采用生长曲线拟合与回归分析可以科学估算大凉山黑猪及其F1代的出栏时间,其中纯种黑猪的拐点体重为71.6 kg、出栏时间为193.4 d,杜杂黑猪为90.3 kg、200.4 d,巴杂黑猪为89.7 kg、198.6 d。
The growth speed of Daliangshan black pigs was slow, its fattening performance was improved obviously by crossbreeding with Duroc boar and Berkshire boar. Using growth curve fitting with the regression analysis could estimate the marketing time and spinodal weight, the pure black pig was 71.6kg and 193.4 days, Duroc hybridization F1 was 90.3 kg and 200.4 days, Berkshire hybridization F1 was 89.7kg and 198.6 days.
