力克斯种母兔营养水平研究

本研究旨在探讨繁殖母兔的能量、粗蛋白等营养需要量.试验设高能量高蛋白(第1组:DE11.31MJ/kg,CP 18.73%)、低能量高蛋白(第2组:DE 10.71MJ/kg,CP 19.54%)、高能量中蛋白(第3组:DE11.31MJ/kg,CP 17.02%)和低能量中蛋白(第4组:DE 10.47MJ/kg,CP 17.48%)4个组.繁殖127窝测定结果表明:怀孕母兔饲粮营养水平为消化能10.47MJ/kg、粗蛋白17.48%、粗纤维14.62%时,产仔数、产仔成活率、初生窝重最高;哺乳母兔饲粮营养水平为消化能10.71MJ/kg、粗蛋白19.54%、粗纤维12.52%时,有利于35日龄断奶仔兔数和断奶窝重的提高.

Study on Nutrition Levels for Brood Rex Rabbit

Present experiment was conducted to study nutrition requirements for energy and crude protein of the brood doe.In the experiment four groups were des igned as high energy high protein group 1 of DE 11.3MJ/kg and CP 18.73%,low ene rgy high protein group 2 of DE 10.7MJ/kg and CP 19.54%,high energy medium protein group 3 of DE 11.3M J /kg and CP 17.02%,and low energy m edium protein group 4of D E 10.47M J /kg and CP 17.48%.The results of127litters show thatwhen the dietfor the pregnantdoe is ofdigestible energy 10.47M J /kg and crude protein17.48%,crude fiber14.62%,the does gotthe highestlittersize,the survivalrate and initialletter weight.A nd when the dietfor the m ilking doe is ofdigestible energy10.71M J /kg,crude protein 19.54% and crude fiber 12.52%,it is favorable to im prove litter size and litter weightat weaning at35d.
