摘要: 对皖南黑猪初生、20、30、60和90日龄的体重和体尺进行测定。统计分析结果表明,皖南黑猪的平均日增重随着日龄的增长而提高,30日龄时头长指标与体重呈显著相关,相关系数为0.852,20、30日龄时胸围指标与体重呈极显著相关,相关系数分别为0.896和0.903,以上指标可以考虑作为留种的依据。

Abstract: The correlation analysis was carried on body weight traits and body size traits of Wannan black pigs at newborn, 20, 30, 60 and 90 days. The results showed that the Wannan black pigs’ average daily gain was enhancing with the day-old increasing. There was significant correlation between body weight and head length at 30 days of age and the correlation coefficient was 0.852. There were highly significant correlation between body weight and chest girth at 20 and 30 days and the correlation coefficients were 0.896, 0.903 respectively. All of the correlation coefficients above could be used for breeding.

Key words: Wannan black pig; body weight; body size
