摘 要: | 为研究不同品种蛋鸡鸡蛋的营养成分,随机抽取43周龄的拉萨白鸡、藏鸡和柳红谷香鸡3个品种蛋鸡的鸡蛋各40枚,进行蛋品质的营养成分测定。结果表明,3个品种蛋鸡鸡蛋的营养成分存在差异,除蛋白质、16种氨基酸、脂肪酸(C18∶3)在3个品种间差异不显著(P>0.05)外,拉萨白鸡蛋、藏鸡蛋与柳红谷香鸡蛋的水分、脂肪酸(C14∶0)存在显著差异(P<0.05),拉萨白鸡蛋、柳红谷香鸡蛋与藏鸡蛋的C17∶0、C22∶6、矿物质元素(Mg、Na)间存在极显著差异(P<0.01),脂肪、C16∶0、C16∶1、C18∶0、C18∶1、C18∶2、C19∶0、矿物质元素(Zn、Cu、Fe、Mn、Ca)在3个品种间存在极显著差异(P<0.01),拉萨白鸡蛋与藏鸡蛋、柳红谷香鸡蛋的矿物质元素(K)相互间存在极显著差异(P<0.01),3个品种的鸡蛋在磷脂、胆固醇、矿物质元素(P)相互间存在显著(P<0.05)或极显著差异(P<0.01)。

Comparative Study on Nutritional Components of Eggs from Different Breeds of Laying Hens |
| |
Abstract: | In order to assess the nutritional components of eggs from different breeds of laying hens, forty eggs from each of the three breeds of laying hens aged 43 weeks, including Lhasa White Chicken, Tibetan Chicken and Liuhongguxiang Chicken, were chosen and used to determine their nutrition constituents. The results showed that except for protein, 16 amino acids and fatty acid (C18∶3) (P〉0.05), there were differences in other nutrition components between eggs from the three breeds of laying hens. Significant differences in moisture content and (C14∶0) content between Lhasa White Chicken eggs, Tibetan Chicken eggs and Liuhongguxiang Chicken eggs were observed (P〈0.05);there were extreme significant differences in content of C17∶0, C22∶6 as well as mineral elements of Mg and Na between Lhasa White Chicken eggs, Liuhongguxiang Chicken eggs and Tibetan Chicken eggs (P〈0.01);extreme significant differences in content of fat, C16∶0, C16∶1, C18∶0, C18∶1, C18∶2, C19∶0 as well as mineral elements of Zn, Cu, Fe, Mn, Ca between the eggs from the three breeds of laying hens were observed (P〈0.01);the content of mineral element of K between the eggs from Lhasa White Chicken, Tibetan Chicken and Liuhongguxiang Chicken was mutually extremely significantly different (P〈0.01);the content of phospholipid, cholesterin and mineral element of P between the eggs from the three breeds of laying hens was mutually extremely significantly different or significantly different (P〈0.05 or P〈0.01). |
