本研究旨在调查发酵蘑菇（Flammulina velutipes）副产品日粮对生长育肥伯克希尔猪生长性能和胴体性状的影响。发酵饲料主要含有40.0%蘑菇副产物、20.0%配合饲料、26.0%米糠和补充0.1%益生菌。将混合的成分在室温下发酵5天。伯克希尔猪（n = 225）被分为五组和三个重复。基础日粮 (C) 被 10% (T1)、30% (T2)、50% (T3) 和 70% (T4) 发酵蘑菇副产品日粮替代。与发酵初始日相比，发酵日结束时发酵日粮中的粗蛋白浓度和总热量显着增加（P < 0.05）。 T2、T3和T4组的增重、饲料效率和胴体重量均显着低于对照组（P < 0.05）。饲喂发酵日粮的猪的胴体等级显着优于饲喂对照日粮的猪（P < 0.05），且发酵日粮组中高等级（1+2级）的比例高于对照组。因此，虽然发酵蘑菇副产品的日粮降低了生长性能和饲料效率，但它提高了伯克希尔猪的胴体等级。
This study was conducted to investigate effects of fermented mushroom (Flammulina velutipes) by-product diets on the growth performance and carcass traits in growing-fattening Berkshire pigs. The fermented diets mainly contained 40.0% mushroom by-product, 20.0% formula feed, 26.0% rice bran and supplemental 0.1% probiotics. The mixed ingredients were fermented for 5 days at room temperature. Berkshire pigs (n = 225) were divided into five groups and three replications. The basal diets (C) were substituted by 10% (T1), 30% (T2), 50% (T3) and 70% (T4) fermented mushroom by-product diets. Crude protein concentration and total calorie in fermented diets were significantly increased (P < 0.05) at the end of fermentation days compared with initial fermentation day. Body weight gain, feed efficiency and carcass weight were significantly lower (P < 0.05) in the T2, T3 and T4 groups than in the control group. Carcass grade was significantly better (P < 0.05) in the pigs fed fermented diets than in the pigs fed control diet and the ratio of high grade (1 plus 2 grades) was higher in the fermented diet groups compared with the control group. Therefore, although a diet of fermented mushroom by-product decreased growth performance and feed efficiency, it improved the carcass grade in Berkshire pigs.
