摘要
珍珠鸡是从国外引进,经人工驯养育成的一个特色品种,其蛋用性能获得了显著进展,为加快蛋产品的开发力度,增加其附加价值,对珍珠鸡蛋和海兰褐鸡蛋蛋品质及营养成分进行比较分析。试验随机抽取新鲜珍珠鸡蛋、海兰褐鸡蛋各100枚,测定其蛋外、内在品质及主要营养成分,采用Duncan新复极差法、皮尔逊相关系数进行比较分析。研究表明,在外部品质方面,海兰褐鸡蛋蛋重高于珍珠鸡蛋15.54g(35.61%),有极显著差异(P<0.01);珍珠鸡蛋蛋壳厚度比海兰褐鸡蛋的蛋壳厚0.14mm(40%),差异极显著(P<0.01);由于蛋重的差异,两种鸡蛋蛋黄比例、蛋白比例、蛋壳比例也均有极显著差异(P<0.01)。在内在品质方面,两种鸡蛋蛋清pH、蛋黄高度、蛋黄系数均无明显差异;珍珠鸡蛋浓蛋白高度比海兰褐鸡蛋的低3.02mm,有极显著差异(P<0.01);浓蛋白系数比海兰褐的高0.87,有显著差异(P<0.05);珍珠鸡蛋蛋黄颜色比海兰褐鸡蛋的颜色大一个罗氏比色值,有显著差异(P<0.05)。在营养成分上,以g/枚为单位,珍珠鸡蛋的主要营养成分除胆固醇高于海兰褐鸡蛋外,其他均低于海兰褐鸡蛋。以g/100g为单位,珍珠鸡蛋水分含量明显低于海兰褐鸡蛋,相差12.62(20.21%),差异极显著(P<0.01),脂肪含量也低于海兰褐鸡蛋,差异显著(P<0.05),相差1.34(4.4%),其它营养成分均高于海兰褐鸡蛋。珍珠鸡蛋是较海兰褐鸡蛋小、壳厚、水分含量低、营养丰富的浓缩型蛋,为珍珠鸡蛋的蛋品开发创造了条件。
Guinea fowl is imported from abroad, with a special variety of artificial trainer parenting into, the egg performance achieved significant progress, efforts to speed up the development of egg products, increase the added value, the comparative analysis of the guinea fowl and Hy-Line brown egg quality and nutrient composition. Test random pearl egg, Hy-Line brown egg the 100 medals, determination of the egg quality and nutrition, and the use of＆amp;nbsp;Duncan ＆#39; s analysis, Pearson correlation coefficient method. Studies have shown that in the external quality, the Hy-Line Brown egg weight than guinea fowl 15.54g （35.61%）, there was a significant difference （P〈0.01）; guinea fowl eggshell thickness Hy-Line brown thick 0.14 mm （40%）,the difference was significant （P〈0.01）; because egg weight differences in the proportion of two kinds of egg yolk protein ratio , the proportion of eggshell were significantly different （P〈0.01）. Including in terms of quality , two kinds of egg albumen pH, yolk height , yolk index were not significantly different ; Guinea fowl egg protein highly concentrated below the Hy-Line Brown chicken 3.02mm,there was a significant difference （P〈0.01）;concentrated protein factor ratio Hy-Line Brown high 0.87,a significant difference （P〈0.05）;Guinea fowl egg yolk color than Hy-Line Brown chicken,a significant difference （P〈0.05）. The nutritional composition, in g/pieces as a unit, the pearl of the main nutrients except egg cholesterol than Hy-Line Brown eggs , the other less than Hy-Line Brown eggs. In g/100 g as a unit, the moisture content pearl egg eggs differ significantly lower than the Hy-Line Brown 12.62 （20.21%）were significantly different （P〈0.01）,fat content is also lower than Hy-Line Brown chicken significant difference（P〈0.05）difference of 1.34（4.4%）,other nutrients were higher than the Hy-Line Brown eggs.Guinea fowl egg is smaller than Hy-Line brown eggs, shell thickness, low moisture content rich nutrition is conce
