摘要
试验研究在相同日粮营养水平下,20.0%的发酵苹果渣日粮、20.0%的苹果渣日粮和常规日粮对雏鹅生产性能和养分代谢率的影响。结果表明,与苹果渣组相比,发酵苹果渣组的料重比降低2.34%(P<0.05),平均日增重提高4.90%(P<0.05),日粮NDF、ADF、CP表观代谢率显著提高(P<0.05),其他指标差异不显著(P>0.05);与常规日粮组相比,发酵苹果渣组的生产性能和养分代谢率各指标差异均不显著(P>0.05)。
The effects of different diets（20.0% of fermented apple pomace,20.0% of the apple pomace and conventional diets）with equal nutrition level on the production performance and nutrient metabolic rate in goslings were studied.The results showed that compared with the apple pomace,the feed / gain ratio in fermented apple pomace group reduced by 2.34%（P0.05）,average daily gain increased by 4.90%（P0.05）,the apparent metabolic rate of NDF,ADF,CP in diet increased significantly（P0.05）.Compared with the conventional diet group,it showed no significant difference in all indicators of production performance and nutrient metabolic rate in fermented apple pomace group（P0.05）.
