摘　　要：为了解北京油鸡不同趾型对鸡蛋感官物理及营养化学品质的影响,选择双五趾、单五趾和双四趾等趾型的北京油鸡,分别对33、43、53、63周龄所产鸡蛋的蛋品质进行对比分析。结果显示:在感官物理指标方面,各周龄的蛋重、蛋壳颜色和蛋黄颜色等指标在不同趾型间差异不显著(P>0.05);43周龄双四趾北京油鸡的蛋壳强度显著高于双五趾和单五趾北京油鸡(P<0.05),且双五趾和单五趾北京油鸡之间差异不显著(P>0.05);43周龄双五趾北京油鸡的蛋黄比例显著高于单五趾北京油鸡(P<0.05);53周龄双四趾北京油鸡蛋白高度和哈氏单位显著高于单五趾个体(P<0.05)。在营养化学指标方面,北京油鸡不同趾型对各周龄鸡蛋中的粗脂肪和卵磷脂(PC)含量的影响不显著(P>0.05);43周龄双五趾北京油鸡鸡蛋干物质含量显著高于单五趾个体(P<0.05);53周龄双四趾北京油鸡全蛋脑磷脂(PE)及丝氨酸磷脂(PS)显著高于单五趾个体(P<0.05),且双五趾和双四趾个体间差异均不显著(P>0.05)。综上所述,北京油鸡趾型对43周龄和53周龄的部分蛋品质性状存在一定的影响。To better understand the effects of different toe patterns of Beijing-You chicken on the characters of egg sensory,physical and nutritional chemical quality traits,the eggs of double-five-toed,single-five-toed and double-four-tored BeijingYou chicken were collected to investigate the egg quality traits at 33,43,53 and 63 weeks of age,respectively.The results showed that,in terms of sensory physical indicators,the egg weight,eggshell color and egg yolk color from each week of age had no significant differences among different toe patterns(P>0.05);The eggshell strength of double-four-toed Beijing-You chicken at 43 weeks of age was significantly higher than those of double-five-toed and single-five-toed Beijing-You chicken(P<0.05),which was not significant from each other(P>0.05);The egg yolk ratio of double-five-toed Beijing-You chicken at 43 weeks of age was significantly higher than that of the single-five-toed ones(P<0.05);The height of protein and Haugh unit from the double-four-toed Beijing-You chicken at 53 weeks of age were significantly higher than those of single-five-toed individuals(P<0.05).In terms of nutritional chemistry indicators,there were no significant effects on the crude fat and lecithin(PC)content in eggs from different toe patterns of Beijing-You chicken at each week of age(P>0.05);The dry matter content of eggs from doublefive-toed Beijing-You chicken at 43 weeks of age was significantly higher than that of single-five-toed individuals(P<0.05);The whole egg cephalin(PE)and serine phospholipid(PS)of double-four-toed Beijing-You chicken at 53 weeks of age were significantly higher than those of single five-toed individuals(P<0.05),and there was no significant difference between double fivetoed individuals and double four-toed individuals(P>0.05).In summary,the toe patterns of Beijing-You chicken affect,some egg quality traits at 43 and 53 weeks of age.
