Keyword:  卵蛋白粉生长发育繁殖性能KM小鼠;
Abstract: 目的 研究含蝇蛆卵蛋白粉饲料对KM小鼠繁殖性能及其胎仔生长发育的影响.方法 记录妊娠鼠、仔鼠生理变化指标,采用修订Fox方案检测各项生长发育指标.结果 不同组别妊娠小鼠体质量增加无显著差异(P>0.05);初生仔鼠数、窝重、平均体质量及各组间仔鼠平均体长、尾长均无显著差异(P>0.05).不同饲料组仔鼠离乳前窝重、仔鼠离乳后体质量变化和食物利用率均无显著差异(P>0.05);不同饲料组仔鼠躯体/生理发育指标:耳廓分离、睁眼、张耳和出毛时间无显著差异(P>0.05),但雌性仔鼠阴道开口和雄性仔鼠睾丸下降较基础饲料组要早(P<0.01).结论 含蝇蛆卵蛋白粉饲料能够满足SPF级KM小鼠生长发育的需要.
