Growth and Biochemistry of White Rabbits from Fujian and New Zealand
-
摘要:
目的 了解福建白兔的生长与生化特性及其与新西兰白兔的差异,为进一步开发利用福建白兔提供科学数据支持。 方法 测定福建白兔与新西兰白兔不同日龄的生长发育情况和90日龄的生化指标,并分别进行品种内性别比较和品种间比较。 结果 福建白兔公兔体重均大于同期母兔体重但差异不显著,35~90日龄日增重公兔显著高于母兔(P < 0.05)。两个品种兔相比,90日龄福建白兔的体重、体长、胸围、耳长、耳宽、免疫球蛋白IgM、IgG、球蛋白、谷氨酰转肽酶、总胆固醇、低密度脂蛋白都低于新西兰白兔,且除低密度脂蛋白差异显著外(P < 0.05),其他差异极显著(P < 0.01);而福建白兔白蛋白、乳酸脱氢酶和总胆红素极显著高于新西兰白兔(P < 0.01)。 结论 福建白兔与新西兰白兔相比,其体型小,生长速度慢,血液生化指标具有总胆固醇低、低密度脂蛋白低和白蛋白高等优点。 Abstract:Objective Growth and biochemistry of white rabbits from Fujian and New Zealand were compared to facilitate the breeding and utilization of the local resource. Method The growth and development of Fujian white rabbit (FWR) and New Zealand white rabbit (NWR) was monitored, and the biochemistry of 90-d-old rabbits determined. Result The average weight of individual male FWRs was generally higher but not significantly (P < 0.05) than that of female rabbits in a same growth period, except in 35-to 90-d-old. At 90-d-old, FWR had significantly lower body weight, body length, chest girth, ear length, ear width, immunoglobulin IgM, IgG, globulin, glutamoacyl transferase, and total cholesterol than NWR at P < 0.01, but at P < 0.05 on low-density lipoprotein (LDL). On the other hand, FWR had significantly higher albumin, lactate dehydrogenase and total bilirubin than NWR (P < 0.01). Conclusion Compared to NWR, the FWR was with characteristics of small body size, slow growth rate, low total cholesterol, low LDL, and high albumin. -
