三个引进品种母猪泌乳力的比较

Lactescence Comparison of Introduced Breed Swine

试验选择了大约克、长白、杜洛克三个品种母猪各10头,从泌乳时间、泌乳次数、泌乳量、初生窝重、20日龄窝重等指标来综合分析不同品种的泌乳力。试验结果表明:大约克母猪和长白母猪的泌乳力显著高于杜洛克母猪(P<0.01),而前二者之间的泌乳力差异不显著(P>0.05)。

In this study, the lactescence of three swine breeds （Yorkshire, Landrace, Duroc） was analyzed and compared from lactation time, lactation frequency, lactation capacity, starting litter weight, and 20-day-old litter weight, respectively. The results showed that the difference of lactescence between Yorkshire and Landrace was insignificant （P〉0.05）, and both of them have much higher lactescence than Duroc （P〈0.01）.
