【摘要】：为探明散养体系下地方品种坝上长尾鸡与海兰褐蛋鸡蛋品质和营养成分是否存在差异,明确饲养方式在蛋品质和营养成分中的作用,在河北省沽源县长梁乡5个自然村共选取12个养殖户(相当于12个重复),每户各放养20只坝上长尾鸡和20只海兰褐商品代蛋鸡鸡雏。在蛋鸡40周龄时,收集3日内的新鲜鸡蛋,每户40个(坝上长尾鸡20个,海兰褐20个),共计480个,进行脂肪酸、胆固醇、微量元素、V_A、V_E、V_(B1)和V_(B2)分析,以及鸡蛋品质测定和鸡蛋中的干物质、粗蛋白、粗脂肪和钙磷分析。结果:两个品种在散养条件下,蛋重、蛋白高度、蛋壳强度、蛋白和蛋黄比例均存在显著差异(P0.05);两品种鸡蛋中脂肪酸或不饱和脂肪酸的含量均没有显著差异(P0.05);脂溶性V_A和V_E在两品种鸡蛋中没有显著差异(P0.05),而V_(B1)和V_(B2)在坝上长尾鸡鸡蛋中的含量显著高于海兰褐鸡蛋(P0.05);坝上长尾鸡鸡蛋的水分含量低于海兰褐蛋鸡,锌含量显著高于海兰褐蛋鸡(P0.05)。研究表明:散养体系下,除鸡蛋V_(B1)、V_(B2)含量外,坝上长尾鸡与海兰褐蛋鸡鸡蛋营养成分没有显著差异。
[Abstract]:in ord to find out that difference between the quality and the nutritional components of the egg quality and the nutritional components of the long tail chicken and the brown egg in the local variety dam in the distribution system, the effect of the feeding mode in the quality of the eggs and the nutrient components is clearly defined, A total of 12 farmers (equivalent to 12 replicates) were selected in 5 natural villages in Changliang Township, the county, Hebei, Hebei Province. At the age of 40 weeks, fresh eggs were collected for 3 days,40 of each household (20 of the long tail-tailed chickens on the dam,20 in the sea and 20 in the sea), and 480 were used for the analysis of fatty acid, cholesterol, trace elements, V _ A, V _ E, V _ (B1) and V _ (B2), as well as the determination of egg quality and the dry matter and crude protein in the egg. Analysis of crude fat and calcium and phosphorus. Results: There was a significant difference in egg weight, egg weight, protein level, egg shell strength, protein and egg yolk ratio in two varieties (P0.05), and there was no significant difference in the content of fatty acid or unsaturated fatty acid in the two varieties (P0.05). The fat-soluble V _ A and V _ E were not significantly different from those of the two varieties (P0.05), while the content of V _ (B1) and V _ (B2) in the eggs of the long-tailed chicken in the dam was significantly higher than that of the white-tail-brown egg (P0.05); the water content of the eggs of the long-tailed chicken in the dam was lower than that of the yellow-brown layer (P0.05). The results showed that there was no significant difference in the nutritional components of egg V _ (B1) and V _ (B2) except the content of V _ (B1) and V _ (B2).
