【摘要】：为更好了解及利用斑嘴野鸭鸭品种优良遗传资源,本研究随机抽取22枚鸭蛋进行测定。通过干燥法、索氏脂肪提取法和凯氏定氮法等相关方法,对斑嘴野鸭鸭蛋的蛋形指数、水分、粗脂肪、粗蛋白、粗灰分和氨基酸等6项指标进行测定。结果表明,斑嘴野鸭蛋形指数为1.40,蛋重均匀而整齐度差异较大,蛋中水分、粗蛋白、粗灰分和粗脂肪含量分别为70.91%、13.17%、4.55%和11.94%。含人体所必需氨基酸质量之和占总氨基酸质量的比为41.85%,营养价值非常高;不饱和脂肪酸油酸的含量为54.08%,有很好的保健功能。通过对斑嘴野鸭的蛋品质及其营养成分的分析与研究,为更好衡量家禽产蛋性能,选育优良斑嘴野鸭品种提供依据。
[Abstract]:In order to better understand and utilize the excellent genetic resources of wild duck breeds, 22 duck eggs were randomly selected for determination. The egg shape index, water content, crude fat, crude protein, crude ash and amino acid of duck eggs were determined by drying method, Soxhlet fat extraction method and Kjeldahl nitrogen determination method. The results showed that the egg shape index of wild duck was 1.40, and the egg weight was uniform and uniform. The contents of water, crude protein, crude ash and crude fat in the eggs were 70.91and 13.174.55% and 11.94respectively. The ratio of the total amino acid mass to the total amino acid mass is 41.85, and the content of unsaturated fatty acid oleic acid is 54.08, which has good health care function. Through the analysis and research on the egg quality and its nutrient composition of the wild duck, this paper provides the basis for the better evaluation of the performance of poultry egg production and the breeding of the fine variety of the wild duck.
