| 摘 要： | 目的]研究鸡蛋暗斑对蛋品质及其抗氧化能力的影响。方法]从饲喂同种日粮、饲养环境相同、同日龄褐壳蛋鸡同一批次所产的褐壳蛋中,用灯光照射法挑选出24枚典型正常蛋、24枚典型暗斑蛋进行试验,并分别对正常蛋和暗斑蛋进行蛋品质、蛋黄抗氧化指标的测定及比较。结果]蛋品质比较:暗斑蛋与正常蛋相比,其蛋形指数、蛋壳强度、蛋重、哈氏单位、蛋白高度、鸡蛋等级、蛋黄颜色、蛋黄重、蛋壳重、蛋清重、蛋壳厚度、蛋黄比重、蛋壳比重、蛋清比重均差异不显著(P>0.05);暗斑蛋蛋壳颜色极显著深于正常蛋(P<0.01)。抗氧化指标比较:暗斑蛋蛋黄的总抗氧化能力(T-AOC)显著低于正常蛋蛋黄的总抗氧化能力(P<0.05),暗斑蛋蛋黄的丙二醛(MDA)含量与正常蛋蛋黄的丙二醛含量相比差异不显著(P>0.05)。结论]与正常蛋相比,暗斑蛋的蛋壳颜色较深,总抗氧化能力较差。

Effects of Dark Spots on Egg Quality and Antioxidant Activity |

| Abstract: | Objective]To study the effect of dark spots on egg quality and antioxidant activity.Methods]Typical normal eggs(n=24)and typical eggs with dark spot(n=24)were selected from the eggs produced by a batch of brown shell layers of the same age which were fed with same diet and were reared under the same rearing environment,respectively.The egg quality and antioxidant activity in egg yolk of the two types of eggs were determined and statistically compared.Results]In terms of egg quality,there were no significant differences in egg shape index,eggshell strength,egg weight,Haugh unit,albumen height,egg class,egg yolk color,egg yolk weight,eggshell weight,albumen weight,eggshell thickness,egg yolk ratio,eggshell ratio and albumen ratio between the two types of eggs(P>0.05);the eggs with dark spot had extremely significantly lower eggshell color value compared to the normal eggs(P<0.01).For the antioxidant activity indexes,the significantly lower total antioxidant capacity(T-AOC)were found in the eggs with dark spot compared to the normal ones(P<0.05);no significant difference in malondialdehyde(MDA)content in egg yolk between the two types of eggs was found(P>0.05).Conclusion]Eggs with dark spot have darker eggshell and lower T-AOC compared to the normal ones. |
