摘　　要：川白獭兔通过导入25%齐卡巨型肉兔血缘后,经过连续3个世代选育,生长发育性能得到了显著提高,并进行统计学分析和差异显著性检验。结果表明:13周龄体质量2497.82 g比川白獭兔2309.56 g提高了188.26 g,差异极显著(P<0.01);23周龄体质量4223.51 g比川白獭兔3582.22 g提高了641.29 g,差异极显著(P<0.01),獭兔毛型比例为100%。After import 25%of the Qika giant meat rabbit bloodline,the growth of the Chuanbai Rex rabbit was significantly improved through three consecutive generations of breeding,and statistical analysis and significant difference tests were conducted.The results showed that at 13 weeks of age,the weight of 2497.82 g increased by 188.26 g compared to 2309.56 g in Chuanbai Rex rabbit,and the difference was extremely significant(P<0.01);At 23 weeks of age,the weight of 4223.51g increased by 641.29g compared to 3582.22g in Chuanbai Rex rabbit and the difference was extremely significant(P<0.01).The proportion of Rex rabbit hair type was 100%.
