Abstract:

本研究旨在明确影响肉兔断奶后窝生长性状和料肉比的重要因素。利用一般线性模型分析了来自5个不同肉兔品种(新西兰白兔,加利福尼亚兔,比利时兔,青紫蓝兔和福建黄兔)的909只173窝肉兔断奶后窝生长和料肉比性状。结果表明,品种和断奶数对断奶窝重(5周龄窝重),窝增重,窝上市体重(10周龄窝重),个体平均上市体重,窝采食量和料肉比的影响极显著(P<0.01)。出生月份对窝采食量影响极显著(P<0.01),对断奶窝重和窝上市体重的影响显著(P<0.05)。比利时兔的断奶窝重、窝增重、窝上市体重、窝采食量和平均上市体重显著高于其他品种,而福建黄兔的上述5项指标显著低于其他品种(P<0.05)。断奶数与断奶窝重、窝采食量、窝增重、窝上市体重和料肉比的回归系数为正且显著。品种、断奶数和出生月份是影响肉兔断奶后窝性状和料肉比的重要因素。本研究的结果为将比利时兔作为杂交的终端父本提供重要依据。
