Abstract: After 7 years' selective breeding and large scale production, the physiognomy features and reproductive performance of B: CBWR rabbit were gradually stablized. The average pregancy rate of one time mating, gestation period, litter size were 81.89%, 31.19±0.13 days, 8.00±0.06 respectively. The average litter weight at 21 day age is 1765.17±27.07g; At 45 day age, the average weanling litter size and weight are 5.38±0.09,1263.29±13.27 g respectively. The average daily gain is 31.03±7.14g within 5 weeks after weaning. The average weight of replacement rab-bits at 60 days is 3930.00 士336.53 g for the male, 4012. 50±325.00 g for the fe-male, the average trunk index is 66.07±3.48.
