【摘要】：本试验旨在研究不同饲粮精氨酸水平对黄羽肉种鸡繁殖性能的影响。试验选用780只36周龄的黄羽肉种鸡作为试验鸡,采用单因素随机分组试验设计分成5个组(饲粮精氨酸水平分别为0.65%、0.80%、0.95%、1.10%和1.25%),每组6个重复,每个重复26只鸡。试验预试验2周,饲喂精氨酸水平为0.65%的饲粮;正试期10周。结果表明:饲粮中添加不同水平精氨酸对试验全期种鸡产蛋率、平均蛋重和料蛋比均没有显著影响(P0.05)。1.10%精氨酸组的产蛋率最高,与0.65%和1.25%精氨酸组相比有提高的趋势(P0.10)。1.25%精氨酸组平均蛋重最低,与其他4组相比均有降低的趋势(P0.10)。饲粮中添加不同水平精氨酸对种蛋蛋壳强度、蛋壳厚度、蛋黄比例、蛋白质含量以及种鸡血浆中丙二醛含量和还原型谷胱甘肽/氧化型谷胱甘肽值均有显著影响(P0.05)。饲粮精氨酸水平对种蛋受精率、孵化率、健雏率和健雏平均出壳重均没有显著影响(P0.05)。由此可见,适度添加精氨酸一定程度上能提高黄羽肉种鸡产蛋率,增强种蛋蛋壳强度和种鸡抗氧化能力。综合分析本试验多项指标,推荐快大型黄羽肉种鸡产蛋高峰期饲粮中精氨酸水平为1.10%。
[Abstract]:The aim of this study was to study the effects of different dietary arginine levels on the reproductive performance of yellow broilers. 780 yellow feather broilers aged 36 weeks were selected as experimental chickens, and were randomly divided into 5 groups (the dietary arginine level was 0.650.800.800.800.95% and 1.25% respectively, 6 replicates in each group, 26 chickens per replica). For 2 weeks, arginine level was 0.65%, and the trial period was 10 weeks. The results showed that different levels of arginine in diet had no significant effect on laying rate, average egg weight and feed / egg ratio of broilers during the whole trial period. The egg laying rate was the highest in the group of P0.05g 路1.10% arginine. Compared with 0.65% and 1.25% arginine groups, the average egg weight was the lowest in P0.10 and 1.25% arginine groups, and decreased in comparison with the other four groups. Different levels of arginine in diet had significant effects on egg shell strength, egg shell thickness, yolk ratio, protein content, plasma malondialdehyde content and glutathione / oxidized glutathione value. The dietary arginine level had no significant effect on the fertilizing rate, hatchability rate, healthy brood rate and average shell weight of the healthy chicks, all of which had no significant effect on the egg fertility rate, hatchability rate and average shell weight of the healthy chicks. It can be seen that the appropriate addition of arginine to some extent can improve the laying rate of yellow broiler hens and enhance the eggshell strength and antioxidant capacity of breeding hens. Based on the comprehensive analysis of several indexes in this experiment, the arginine level in the diet of fast large yellow feather broiler was recommended to be 1.10 in the peak period of laying eggs.
