| 摘 要： | 为探讨定远母猪及其杂交后代的繁殖性能,通过对定远猪、长白、大约克夏猪及其杂交一代的母猪生产记录资料进行统计分析,结果表明:定远母猪及其杂交一代的长定、大定母猪都具有较高的产仔数,且与纯繁的长白和约克夏母猪相比,均呈极显著的差异(p<0.01);大定和长定二元母猪繁殖性能的各项指标都表现出明显的杂种优势.其中以长定略优于大定,但二者之间差异不显著(p>0.05).

| Abstract: | To study the reproductivity of Dingyuan Sow and filial-generation, the production record of Dingyuan Sow, Landrace, Yorkshire and first filial-generation sows were analysed. The results showed that little size of Dingyuan Sow and it first filial-generation is very high, and compared with pure-bred Landrace and Yorkshire sow little size, there were significant difference (p<0.01). There were obvious heterosis in every index of Yorkshire Dingyuan and Landrace Dingyuan second filial-generation sow reproductivity, and that of Landrace Dingyuan sows is better than of Yorkshire Dingyuan sows, but there was no difference between Landrace Dingyuan and Yorkshire Dingyuan sows (p>0.05). |
