摘要
将1 188枚种蛋随机码放在6个蛋盘内,同机入孵,每盘为1 个试验重复。于入孵的第6、9、12、15、18 和21天从各盘取出36个胚蛋用于测定蛋清葡萄糖的含量;胚质量及其水分、蛋白质和脂肪含量;肝脏质量、水分和脂肪含量;卵黄囊质量、卵黄脂类及其脂肪酸的含量。结果表明,随着孵化时间的增加,肝脏的脂肪含量不断增加,但胚胎的水分含量、蛋清的葡萄糖含量和卵黄囊质量则不断减少,脂肪在孵化的第12 天含量最低,蛋白质在孵化的第6、12和15天含量较高。相对肝质量与胚胎的水分含量正相关,与孵化第15天的卵黄棕榈酸和油酸分别为正相关和负相关。卵黄硬脂酸含量与孵化第6天的亚油酸和孵化第12天的油酸均为负相关,但与孵化第6 和15 天的花生四烯酸均正相关。
hatching eggs were put randomly in 6 incubator trays for incubation. Each tray was a trial replication. Samples were collected at Day 6, 9, 12, 15, 18 and 21 of incubation to determine albumen glucose content; weight, moisture, protein, fat content of embryo; weight, moisture, fat content of liver; and lipid, fatty acids content, weight of yolk sac. The results showed that liver fat content increased and embryo moisture, albumen glucose content, yolk sac weight decreased with hating days increasing. Embryo fat and protein content were changeable in incubation period, the former was the lowest at Day 12 of incubation, the latter was higher in Day 6, 12, 15 of incubation. Relative liver weight was positively correlated to liver moisture content throughout incubation, positively and negatively correlated respectively with yolk palmitic acid and oleic acid at Day 15 of incubation. Yolk stearic acid content was negatively correlated to linoleic acid at Day 6 and oleic acid at Day 12, but positively correlated to arachidonic acid at Day 6 and Day 15 of incubation.
