| 摘 要： | 【目的】研究日粮含不同水平的脱脂DDGS对蛋鸡生产性能、蛋品质和血清生化指标的影响。【方法】选用960只67周龄的海兰褐蛋鸡,随机分为4个处理,每个处理4个重复,每个重复60只鸡。对照组饲喂玉米-豆粕型基础日粮,试验Ⅰ组、Ⅱ组、Ⅲ组DDGS占日粮的比例分别为12%、18%和24%,试验期8周。【结果】各试验组的采食量、蛋形指数、蛋壳厚度与对照组无显著差异(P0.05),但各试验组蛋黄颜色显著加深,平均蛋重显著降低(P0.05);与对照组相比,试验Ⅰ组、Ⅱ组料蛋比、产蛋率和哈夫单位无显著差异(P0.05),试验Ⅲ组料蛋比和哈夫单位显著提高,产蛋率显著降低(P0.05);各组之间血清中钙、磷、甘油三酯、高密度脂蛋白和尿素氮无显著差异(P0.05)。【结论】日粮中脱脂DDGS使用量不高于18%时,对蛋鸡料蛋比、产蛋率、蛋品质及血清生化指标无不良影响,但会降低蛋重;24%的用量会提高料蛋比,降低产蛋率和蛋重。

| Abstract: | 【Objective】 An experiment was conducted to study the effects of dietary content of de-oiled distillers dried grains with solubles (DDGS) on production performance, egg quality and serum biochemical indexes in laying hens. 【Method】Nine hundred and sixty Hy-line brown laying hens of 67 weeks old were randomly devided into 4 groups, each of which was replicated four times with sixty hens per replicate. The control group was fed with basal diet, and test I,test II and III groups were fed with diet containing 12%, 18% and 24% DDGS, respectively, for 8 weeks. 【Result】 In the whole experimental period, no significant differences (P＞0.05) in feed intake, egg shape index, and eggshell thickness were observed among the four groups. However, the test groups had lower egg weights and deeper yolk color than control group (P＜0.05). Compared with control group, there were no significant differences in feed-egg ratio, laying rate and Haugh unit in test I and test II (P＞0.05), but test III had higher feed-egg ratio and Haugh unit,and lower laying rate (P＜0.05). No significant differences (P＞0.05) in serum biochemical indexes (Ca, P, TG, HDL and BUN) were observed among the four dietary treatments groups. 【Conclusion】 If dietary content of DDGS is less than 18%, there is no negative effects on feed-egg ratio, laying rate,egg quality and serum biochemical indexes in laying hens,but egg weight will be decreased. However, the feed-egg ratio will be increased and laying rate and egg weight will be decreased when the contens is up to 24%. |
