【摘要】 在相同饲养管理条件下,对7世代贵州剑白香猪两品系生长发育和繁殖性能进行测定。结果显示,两品系2~6月龄体重、体高、胸围两两差异不显著(P>0.05);2月龄体长、腹围两两差异不显著(P>0.05);6月龄体长差异显著(P<0.05),腹围差异极显著(P<0.01);产仔数、初生个体重、初生窝重、断奶个体重、断奶仔猪数两两差异不显著(P>0.05);泌乳力、断奶窝重两两差异极显著(P<0.01),日增重低;7世代剑白香猪体重体尺均小于零世代。全白毛系,体型矮小、生长发育缓慢,是较为理想的实验动物选育群。更多还原

【Abstract】 The growth traits and reproductive performance of two strains of Jianbai Xiang pig were determined in the same feeding conditions.The results showed that the two strains had small body size and grew slowly;the seventh generation Jianbai Xiang pigs were lighter in weight and smaller in body size than the zero generation Jianbai Xiang pigs.Strain Ⅱ was more suitable to be used as experimental animal for its whole white coat,small body size and low average daily gain.更多还原
