摘　　要：为探讨育肥兔饲养密度对生产性能和成活率的影响,于2020年夏季和秋季分别选择540只35日龄断奶的伊高乐商品代肉兔,随机分为3个组,每组180只,公母各半。试验Ⅰ组(低密度组)每笼养殖4只,试验Ⅱ组(中密度组)每笼养殖5只,试验Ⅲ组(高密度组),每笼养殖6只。其笼具规格为50 cm×60 cm×30 cm(长×宽×高),折合饲养密度为13.33只/m^(2)、16.67只/m^(2)和20.00只/m^(2)的笼底面积。试验兔有专人管理,自由采食,自由饮水。试验期35 d。试验结果表明:在本试验条件下,夏秋两个季节,肉兔育肥期饲养密度为13~20只/m^(2),无论是日增重、料重比,还是成活率,均没有显著差异(P>0.05)。每个养殖场可根据季节特点、环境设施条件和管理水平,灵活掌握。试验还发现,肉兔育肥期死亡的主要疾病是肠炎,约占死亡总数的75%,其次是肺炎,占11%左右,同时还要重视球虫病的预防工作。In order to explore the effects of fattening rabbit stocking density on production performance and survival rate,54035-day-old HYCOLE commercial meat rabbits were selected in the summer and autumn of 2020,and they were randomly divided into three groups,each with 180,and half of the male and female.Experiment groupⅠ(low density group)cultured 4 animals per cage,andⅡ(medium density group)cultured 5 animals per cage,andⅢ(high density group)cultured 6 animals per cage.The cage size is 50 cm×60 cm×30 cm(length×width×height),which is equivalent to 13.33,16.67 and 20 animals per square meter of cage bottom area.The animals eat and drink freely.The trial period is 35 days.The test results showed that there was no significant difference in daily weight gain,feedto-weight ratio,or survival rate(P>0.05)under the stocking density of meat rabbits were from 13 number/m^(2) to 20 number/m^(2) in summer and autumn.Each farm can be flexibly controlled according to seasonal characteristics,environmental facility conditions and management level.This experiment also found that enteritis was the main cause of death during the fattening period of the rabbits,accounting for about 75%of the total deaths,followed by pneumonia,accounting for about 11%.At the same time,attention should be paid to the prevention of coccidiosis.
