| 摘 要： | 【目的】研究非淀粉多糖酶在饲喂玉米-豆粕-杂粕型日粮中对海兰褐蛋鸡生产性能及营养物质代谢率的影响。【方法】试验选取1 600只23周龄海兰褐蛋鸡,随机分成4个试验组,每组10个重复,每个重复16只鸡。正对照组(PC组)饲喂正常能量水平的基础日粮;负对照组(NC组)饲喂在PC组日粮的基础上降低628 kJ/kg能量水平的日粮;复合非淀粉多糖酶分别在NC组日粮中添加复合非淀粉多糖酶l和复合非淀粉多糖酶2。【结果】在玉米-豆粕-杂粕型日粮中添加非淀粉多糖酶能够降低海兰褐蛋鸡采食量和料蛋比,提高各养分代谢率,但差异不显著,对于蛋重没有影响。【结论】在蛋鸡玉米-豆粕-杂粕型日粮中添加非淀粉多糖酶,能够替代一部分油脂(2 kg豆油,628 kJ/kg能量)水平,并且不影响蛋鸡生产性能。

| Abstract: | 【Objective】 This project performed aims to study the effect of non-starch polysaccharide enzyme (NSP Enzyme) on growth and nutrient metabolic rate in 23 weeks Hyline brown hens.【Method】 One thousand and six hundred hyline brown hens aged 23 weeks were randomly divided into 4 experimental groups with 10 replicates in each group, 16 chickens in each replicate. The positive control group (group PC) was fed basic diet with normal energy level; The negative control group (NC group) was fed a diet tin which the metabolizable energy (ME) level of 628 KJ/kg was reduced in comparison with the PC group diet; The compound non-starch polysaccharide enzyme l and the compound non-starch polysaccharide enzyme 2 were added to the diet of NC group, respectively.【Result】 The results showed that in comparison with the negative control group,.the addition of non-starch polysaccharide in corn soybean miscellaneous diets could reduce hyline brown hens feed intake and feed egg ratio, and improve the nutrient metabolic rate, but the difference was not significant, which had no effect on egg weight .【Conclusion】 The addition of non-starch polysaccharides enzyme to the corn soybean meal miscellaneous meal diet can replace part of the oil (628 KJ/kg AME energy) level, and does not affect the production performance of laying hens. |
