Ge-132对绍兴鸭种蛋品质的影响

将330只170日龄绍兴鸭随机分成5组。第Ⅰ组为对照组,仅喂基础日粮;第Ⅱ、Ⅲ、Ⅳ、Ⅴ组在基础日粮中分别添加100、200、400、600 mg/kg Ge-132,并在试验结束前1周开始连续收集种蛋,各组分别取150枚种蛋,孵化。结果表明:①各试验组蛋中锗含量随着日粮中Ge-132添加水平的增加而升高,与对照组差异极显著(P<0.01)。②各试验组种蛋的受精率和孵化率均高于对照组。其中添加200 mg/kg Ge-132时受精率最高,为97.33%;添加400 mg/kg Ge-132时受精蛋孵化率以及入孵蛋孵化率均最高,分别为90.98%和86.43%。③随着日粮中Ge-132水平的增加,雏鸭的初生重呈降低趋势。研究表明,在日粮中添加Ge-132可以生产富锗鸭蛋,并能明显改善种蛋的品质,提高种蛋的受精率和孵化率。

Effects of Ge-132 on the breeding egg quality of Shaoxing duck

330 170-days Shaoxing ducks were randomly divided into 5 groups.The first group was control group,was fed with basic diets;the 2nd,3rd,4th,5th group fed with basic diets adding 100,200,400,600 mg/kg Ge-132 respectively.and collected breeding eggs 1 week before the end of the experiment.150 breeding eggs were taken to hatch.The main results were shown as follows:①The contents of germanium in eggs of all testing groups increased as that in diet did(P<0.01).②All testing groups' fertility and hatchability were significantly higher than that of control group.The fertility was the highest(97.33%)in group Ⅲ(200 mg/kg Ge-132);The hatchability of fertilization eggs and all eggs were the highest in group Ⅳ(400 mg/kg Ge-132),which were 90.98% and 86.43% respectively.③The newborn ducks' weight decreased along with the increasing of diet Ge-132 level.The studies showed that Shaoxing ducks fed with basic diets adding Ge-132 can lay high germanium eggs.Feeding this way can mildly improve egg quality,increase the egg's fertility and hatchability.
