【摘要】 连续三年在相同的繁殖季节，使用齐卡Ｎ系母兔１４８只，分别观察测定了四种不同营养水平组合日粮对不同繁殖状态母兔繁殖能力的影响。结果表明：在延期繁殖（母兔断奶后再配种）条件下，不同能量、蛋白水平对母兔繁殖性能的影响差异不显著（Ｐ＞０。０５），但中能高蛋白（ＤＥ１０．８８兆焦／公斤、ＣＰ１９％）的第３组日粮略胜于其它组合。由此得出，在引延期繁殖的ＺＩＫＡ能繁母兔，适宜的营养水平为：消化能（ＤＥ）１０兆焦／公斤，粗蛋白（ＣＰ）１９％，粗纤维（ＣＦ）１０％。在母兔进行半频密繁殖（母兔产后第１４天开始配种）情况下，高能高蛋白（ＣＤＥ１２．１３兆焦／公斤、ＣＰ１９％）饲粮对提高繁殖性能的效果明显优于高能低蛋（ＤＥ１２．１３兆焦／公斤，ＣＰ１５％）和低能低蛋白（ＤＥ１０．８８兆焦／公斤）和ＣＰ１５％）饲粮（Ｐ＜０．０５），尤其对提高母兔泌乳力效果明显（Ｐ＜０；０１），因此，实行频密（产后立即配种）或半频密繁殖的母兔，适宜营养水平为消化能１２兆焦繁殖的母兔，适宜营养水平为消化能１２兆焦／公斤，粗蛋白１９％，粗纤维９－１２％．更多还原

【Abstract】 ZIKA breeding female rabbits were investigated for the feeect of dictary nutitional level on their reproductive perfotmance。The experiments were executed during the similar periods inthree successive years and fow nutuuition combinations were examined :①DE(digestive energy)12MJ/kg, CD(crude protein)19%and CF(crude fibre) 9%;②DE12MJ/kg、CP15%andCF8%;③DE 11 MJ/kg、CP19%and Cf 10%;④DE11MJ/kg、CP15%and CF 10%, The re- sults showed that for the unintensive reproducing rabbits,no significant difference(P>0.05)was found in reproduction between the different nutition supplies,but the combination 3 tendedbetten than the others; For the Semi-intensive rabbits,both high dietary energy and proteinwere significantly betten than low nutition levels(P<0.05).The high nutition supply was par-ticularly able to promote milk production, It is recommanded that the combination of DE12 MJ/kg,CP19%and CF9-12%is suitable for the rabbits both intensive and Semi- reproduction。更多还原
