摘要
为了了解不同生长阶段长大二元母猪的生长性能,试验测定503头长大二元母猪初生、2月龄、4月龄和6月龄的体重和体尺指标,并分析6月龄体重与6月龄体尺之间的相关和通径分析,以及6月龄体尺性状对6月龄体重的直接影响和间接影响以及决定程度的大小。结果表明,长大二元母猪表现出前期生长较慢,后期生长较快的特点;6月龄体重与6月龄体尺间存在或大或小的相关关系;体长和胸围对6月龄体重的决定程度较高。试验结果对实际生产有较好的指导作用。
The body weight and body measurements of binary sows at birth,2,4,6 months were measured,and data of 503 binary sows were used to carry correlation and path analysis on performance traits,and the direct effects,indirect effects and size of the decisive coefficient were analyzed.The results show that the binary sows grows slowly in early stage,but faster in the later.There are a large or small correlation among body weight and body size.Body length and heart girth have a greater weight determination.The ex-perimental results are instructive to practical production.
