| 摘 要： | 为研究不同中性洗涤纤维(NDF)水平日粮对妊娠母兔繁殖性能及血清生化指标和激素的影响,探讨适宜的NDF需要量,将100只体质量相近、胎次和配种日期基本一致的经产新西兰母兔随机分为5组,每组20只,分别饲喂含24%、27%、30%、33%和36%5种NDF水平的日粮。结果表明:日粮NDF水平对妊娠母兔窝产仔数和初生个体质量无显著影响(P0.05),对窝产活仔数、初生窝质量和窝活仔质量影响显著(P0.05),均以30%NDF组最高。30%NDF组血清蛋白质和葡萄糖含量及24%NDF组甘油三酯含量显著高于36%NDF组(P0.05),血清尿素氮和胆固醇浓度不受NDF水平显著影响(P0.05)。随NDF水平升高,血清IGF-1、E2、P4和PRL水平呈先升高后降低趋势,30%NDF组显著高于24%和36%NDF组(P0.05)。综合分析,妊娠母兔日粮最适宜的NDF水平为30%。

| Abstract: | Experiment was conducted to determine the effects of dietary NDF level on reproductive performance,serum biochemical indices and hormone levels of gestating rabbits,and to discuss the appropriate requirements of NDF.100 Multiparous female New Zealand rabbits which had similar body weight,parity and breeding time were randomly divided into 5 treatments of 20 rabbits each.They were fed with different NDF levels in each diet (24%,27%,30%,33% and 36%,respectively).The results showed:Dietary NDF levels had no significant influence on total litter size and nascent individual weight (P>0.05) of gestating rabbits,but its live litter size,total litter weight and litter live weight at birth which were the highest in 30% NDF group were affected significantly (P<0.05).Protein and glucose content in serum of 30% NDF group and triglyceride content of 24% NDF group were significantly higher (P<0.05) than those in 36% NDF group.The concentrations of urea nitrogen and cholesterol were not affected (P>0.05) by dietary NDF levels.The serum levels of IGF-1,E2,P4 and PRL tended to rise then drop with the increase of dietary NDF levels,and they were significant higher (P<0.05) in 30% NDF group than in 24% and 36% NDF groups.According to the results obtained above,we concluded that the appropriate dietary NDF level for gestating rabbits was 30%. |
