日粮添加矿源性黄腐酸对肉鸭生产性能和生化指标的影响
Effects of Dietary Fulvic Acid on the Performance of Ducks and the Biochemical Index
摘要
Abstract
Objective] The aim was to study the effects of ore-derived fulvic acid on production performance of meat duck.[Method] 1-day-old Cherry Valley duck 480, were randomly divided into four groups(control group, test groupⅠ, test group Ⅱand test group Ⅲ), fed the corn-soybean meal diets, each containing 0‰, 0.25‰ , 0.50‰ and 0.75‰ of ore-derived fulvic acid.Effects of dietary fulvic acid on the production performance of meat ducks were studied.[Result]Adding different proportions of fulvic acid, duck weight, weight gain, feed in-take and feed conversion ratio had no significant effect (P<0.05), but had a significant impact on the individual week-old (P>0.05);Diet-ary fulvic acid had no significant effect on total protein concentration of duck serum (P>0.05), blood urea nitrogen concentration of 0.5‰and 0.75‰ group was significantly larger than the other two groups (P<0.05), uric acid concentration increased significantly along with the fulvic acid concentration in the diet (P<0.05), but 0.25‰ group was significantly lower than other groups (P<0.05); Fulvic acid had a significant influence (P<0.05) on urea nitrogen and uric acid in manure, uric acid and urea nitrogen excretion was significantly reduced ( P<0 .05), along with increasing dietary fulvic acid content.[Conclusion] Dietary fulvic acid can improve feed utilization of nitrogen.In terms of improving the feed efficiency, adding 0.75‰ fulvic acid is preferably in duck diet.关键词
