林下和虫子养鸡的鸡蛋品质对比研究

Egg Quality Comparison between the Chicken Raised in Forest and that Fed with Insects

以林下放养和用虫子饲养的鸡产下的蛋为材料,从鸡蛋的外观和营养成分对两种蛋的品质进行对比研究。结果表明:两种鸡蛋品质存在差异,两种鸡蛋的蛋质量、蛋密度、蛋白质量、蛋白pH值、水分、灰分、蛋白质、脂肪、钙、磷、铁11个指标存在极显著差异(P<0.01),蛋黄质量、蛋黄pH值等存在显著性差异(P<0.05)。

The quality of eggs from the hens raised in forest and fed with insects were compared in egg appearance and nutrition constituents in the present work. The results showed that there were significant differences between two kind of eggs in weight, density, egg white weight, pH value of egg white, moisture content, ash content, protein, fat, calcium, phosphorus, and ferrum etc （P 〈 0.01 ）. Also, obvious differences between two types of eggs were investigated in yolk weight, ant yolk pH value （P 〈 0.05）.
