【摘要】：[目的]研究矿源性黄腐酸(Fulvic acid,FA)对肉鸭生产性能的影响。[方法]选取1日龄樱桃谷肉鸭480只,采用单因素试验设计,随机分为4组,对照组、试验组Ⅰ、试验组Ⅱ、试验组Ⅲ分别饲喂含0、0.25‰、0.50‰和0.75‰的矿源性FA的玉米-豆粕型饲粮,研究矿源性黄腐酸对肉鸭生产性能的影响。[结果]饲粮添加不同比例的FA对肉鸭全试验期的体重、增重、采食量和料重比没有显著影响(P0.05),但对个别周龄的体重、采食量和料重比有显著的影响(P0.05);FA对血清总蛋白浓度没有显著影响(P0.05),试验组Ⅱ和试验组Ⅲ尿素氮浓度显著大于其他2组(P0.05),尿酸浓度随着饲粮中FA含量的增加而显著增加(P0.05),而试验组Ⅰ尿酸浓度显著低于其他组(P0.05);FA对粪中的尿素氮和尿酸含量有显著影响(P0.05),随着肉鸭日粮FA含量的增加,排泄物中尿酸和尿素氮的含量显著降低(P0.05)。[结论]肉鸭饲粮中添加黄腐酸钾能够提高饲料氮的利用率,生产中肉鸭饲粮中的FA含量以0.75‰为宜。
[Abstract]:[Objective] to study the source of fulvic acid (Fulvic acid, FA) on the production performance of duck. 1 day old ducks 480 [method], using the single factor experiment design, were randomly divided into 4 groups, the source FA control group, experimental group I, II, III test group test group were fed diets containing 0, 0.25 per thousand, 0.50 per thousand and 0.75 per thousand of the corn soybean diet, influence Study on the ore source of fulvic acid on the production performance of duck. [results] diet adding different proportions of FA on duck whole experimental period of body weight, weight gain, feed intake and feed conversion ratio has no significant effect (P0.05), but the individual week old body weight, feed intake and feed conversion ratio has a significant effect (P0.05); FA had no significant effect on serum total protein concentration (P0.05), experimental group and the experimental group III urea nitrogen concentration was significantly higher than the other 2 groups (P0.05), uric acid concentration increased with increasing FA content in the diet (P0.05), and the concentration of uric acid was significantly lower than that of group I (P0.05); the other group has a significant effect on fecal FA in urea nitrogen and the content of uric acid (P0.05), with the increase of duck diet FA content, the content of uric acid and urea nitrogen excretion was significantly lower (P0.05). [Conclusion] the addition of fulvic acid potassium in meat duck diet can improve the feed utilization rate of nitrogen, the content of FA in the diet of meat duck production to 0.75 per thousand.

【正文快照】： 矿源性黄腐酸(Fulvic acid,FA)是从低级别煤(泥煤、褐煤和风化煤)中提取出来的芳香族羟基羧酸类物质,含有较多的活性基团,因此可激活多种酶活性,从而加强细胞内呼吸,调节组织新陈代谢并调节其生理功能。研究表明,矿源性FA作为饲料添加剂,可使动物食欲增加,使产蛋率提高15.5%,
