摘　　要：试验旨在对道州灰鹅和狮头鹅的蛋品质、营养成分进行测定和对比分析。选取80周龄的道州灰鹅和狮头鹅母鹅各60只,公鹅各12只,每个品种随机分为12个重复,每个重复1只公鹅、5只母鹅。在相同饲粮和管理方式下,饲养4 w后,各收集60枚鹅蛋用于检测分析蛋品质相关指标。结果显示:道州灰鹅的蛋黄比率显著高于狮头鹅(P<0.05)。道州灰鹅蛋中的水分含量显著低于狮头鹅(P<0.05),粗脂肪含量显著高于狮头鹅(P<0.05)。两种鹅蛋中氨基酸指标均无显著差异(P>0.05),谷氨酸、天冬氨酸、亮氨酸含量比较丰富。道州灰鹅蛋中硬脂酸含量显著低于狮头鹅(P<0.05),肉豆蔻酸、棕榈油酸、亚油酸、α亚麻酸、二十碳三烯酸、花生四烯酸、二十二碳六烯酸、不饱和脂肪酸总量、不饱和脂肪酸与饱和脂肪酸的比值均显著高于狮头鹅蛋(P<0.05)。研究表明,道州灰鹅蛋品质和营养成分较优,具有作为优质和特色禽产品资源开发利用的潜力。The aim of this experiment was to determine and compare the egg quality and nutritional composition of Daozhou grey goose and Lion-head goose.A total of 80 week-old Daozhou grey goose,Lion-head goose,60 female geese and 12 male geese were selected.Each breed was randomly divided into 12 replicates,with one male goose and five female geese per replicate.Under the same diet and management mode,60 goose eggs were collected for four weeks to detect and analyze the related indexes of egg quality.The results showed that the yolk ratio of Daozhou grey goose was significantly higher than that of Lion-head goose(P<0.05).Water content in eggs of Daozhou grey goose was significantly lower than that of Lion-head goose(P<0.05).The crude fat content was significantly higher than that of Lion-head goose(P<0.05).There were no significant differences in amino acid indexes between the two geese eggs(P>0.05),and the concentrations of glutamic acid,aspartic acid and leucine were abundant.The stearic acid content in Daozhou grey goose eggs was significantly lower than that in Lion-head goose eggs(P<0.05),while the myric acid,palmitoleic acid,linoleic acid,α-linolenic acid,eicosatrienoic acid,arachidonic acid and docosahexaenoic acid,the total amount of unsaturated fatty acid and the ratio of unsaturated fatty acid to saturated fatty acid were significantly higher than those in Lion-head goose eggs(P<0.05).The results show that the quality and nutritional composition of Daozhou grey goose eggs are better,which have the potential to be used as high-quality and characteristic poultry product resources.
