【摘要】：为研究温州地区不同鸡种间的蛋品质差异,试验对温州地区具有代表性的4个品种鸡蛋品质进行测定。结果表明:绿雁鸡蛋的蛋形指数显著高于褐壳鸡蛋和本地土鸡蛋(P0.05);褐壳鸡蛋蛋重显著高于其他3种鸡蛋(P0.05);灵昆鸡蛋、绿雁鸡蛋、本地土鸡蛋的哈氏单位显著大于褐壳鸡蛋(P0.05),褐壳鸡蛋的蛋白高度显著大于其他3种鸡蛋(P0.05);4个品种鸡蛋的蛋黄颜色和蛋黄重之间差异显著(P0.05),其中绿雁鸡蛋蛋黄比率显著大于其他3个品种(P0.05);绿雁鸡和灵昆鸡的蛋壳强度、蛋壳厚度显著低于褐壳鸡蛋(P0.05),需进一步改善。相关性分析表明,灵昆鸡和绿雁鸡的蛋黄色、蛋白高度与其他性状的相关性均不显著(P0.05),而蛋重和蛋黄重呈极显著正相关(P0.01),哈氏单位和蛋白高度均呈极显著正相关(P0.01)。不同鸡种间的蛋品质差异性为蛋品质遗传改良提供了基础。从蛋品质改良的角度来看,温州地方2个鸡种具有蛋重小、哈氏单位高、蛋白质量好、蛋黄比率高等资源优势,具有较好的育种前景。
[Abstract]:In order to study the egg quality difference among different chicken breeds in Wenzhou area, the egg quality of 4 representative varieties in Wenzhou area was tested. The results showed that the egg shape index of green goose eggs was significantly higher than that of brown shell eggs and native eggs (P0.05); the egg weight of brown shell eggs was significantly higher than that of other three kinds of chicken eggs (P0.05); The protein height of brown shell eggs was significantly higher than that of other three kinds of chicken eggs (P0.05), and the egg yolk color and yolk weight of four varieties of eggs were significantly different (P0.05), among which the egg yolk ratio of goose eggs was significantly higher than that of native eggs (P0.05). The eggshell strength of green goose and Lingkun hens was significantly higher than that of the other three breeds (P0.05). Egg shell thickness was significantly lower than that of brown egg (P0.05), which needed to be further improved. The correlation analysis showed that there was no significant correlation between egg yellow, protein height and other traits in Lingkun chicken and green goose chicken (P0.05), but the egg weight and yolk weight were significantly positive correlation (P0.01). The difference of egg quality among different chicken breeds provides the basis for genetic improvement of egg quality. From the point of view of egg quality improvement, the two chicken breeds in Wenzhou have the advantages of small egg weight, high Hashi unit, good protein content and high egg yolk ratio, so they have good breeding prospects.
