Abstract

The research was carried out to investigate correlations between breeder age, egg cholesterol content, blood cholesterol level and hatchability of broiler breeders. 2. Egg cholesterol content increased with increased breeder age. The mean yolk cholesterol contents (mg per g yolk) were 10.47+/-0.28, 15.34+/-0.65 and 15.64+/-0.71 mg/g at 28, 45 and 65 weeks of age, respectively. 3. There were positive correlations between yolk weight and yolk cholesterol content (mg/g yolk) (r=01.941; P<0.01) and egg cholesterol content (mg/egg) (r=0.980; P<0.01). 4. Negative correlations were found between egg yolk cholesterol content and hatchability of fertile eggs (r=-0.345; P<0.05), fertility ratio (r=-0.609; P<0.01) and hatchability of total eggs (r=-0.574; P<0.01). 5. The mean blood cholesterol levels were 165.1+/-11.04, 166.5+/-11.97 and 179.5+/-11.33 mg/dl at 28, 45 and 65 weeks of age, respectively.

摘要

开展该研究以调查种鸡年龄、蛋胆固醇含量、血液胆固醇水平与肉种鸡孵化率之间的相关性。2. 蛋胆固醇含量随种鸡年龄增长而增加。28、45和65周龄时，蛋黄胆固醇平均含量（每克蛋黄毫克数）分别为10.47±0.28、15.34±0.65和15.64±0.71毫克/克。3. 蛋黄重量与蛋黄胆固醇含量（毫克/克蛋黄）（r = 0.941；P<0.01）以及蛋胆固醇含量（毫克/蛋）（r = 0.980；P<0.01）之间存在正相关。4. 发现蛋黄胆固醇含量与受精卵孵化率（r = -0.345；P<0.05）、受精率（r = -0.609；P<0.01）和总蛋孵化率（r = -0.574；P<0.01）之间存在负相关。5. 28、45和65周龄时，血液胆固醇平均水平分别为165.1±11.04、166.5±11.97和179.5±11.33毫克/分升。
