摘要
采用单因子试验设计,将发酵茯苓作为添加剂以0.15%,0.20%,0.25%三个梯度添加于基础日粮中,并与添加0.20%未发酵茯苓组,添加抗生素组以及基础日粮组相对照,研究其对断奶仔猪生长性能影响。饲养周期为28 d。结果表明,和对照组相比,日粮中添加发酵茯苓饲料添加剂能增强断奶仔猪食欲,提高断奶仔猪采食量,日增重和降低断奶仔猪腹泻率。和添加抗生素组相比,添加发酵茯苓组在料肉比方面不如抗生素组。和添加未发酵茯苓组相比,添加发酵茯苓组断奶仔猪生长性能和腹泻率均要优于添加未发酵茯苓组。通过对6个处理比较,发现发酵茯苓添加水平以0.20%为宜,其平均日采食量、平均日增重、腹泻率同基础日粮组和抗生素组相比均差异性显著(P<0.05),为发酵茯苓饲粮添加剂应用奠定基础。
A single factor deaign was adopted, and compared with 0.20% unfermented poria cocos group, antibiotics group and basal diet group, the fermented poria cocos was adding to basal diet in three gredients as 0.15%, 0.20% and 0.25% to study the influence of fermented poria cocos to the growth performance of the weaned piglets. Breeding cycle was 28 days. The results showed as follows： compared with the control group, the basal diet with fermented poria cocos could enhance the appetite of weaned piglets, and improve the feed intake, daily gain and diarrhea rate. compared with the antibiotics group, the fermented poda cocos was worse than it in the feed conversion ratio, compared with the unfermented poda cocos group, the fermented poria cocos group was better on the growth performance and diarrhea rate. The study showed that the best adding level of fermented poda cocos was 0.20% by comparing with the six processed group, its average daily feed intake, average daily gain, diarrhea rate were significant difference （P〈0.05） compared with basic diet group and antibiotic group, what laid a good foundation for the application of fermented poria cocos.
