The objective of the present study was to determine the effects of dietary supplementation of the combination of multistrain probiotics and Castanea crenata shell extract (MPC) on growth performance, nutrient digestibility, fecal microbial shedding, meat quality, noxious gas emissions, and blood parameters in finishing pigs. A total of 150 pigs were used in a 10-weeks feeding trial. Dietary treatment groups were as follows: CON, basal diet; TRT1, basal diet + 0.1% MPC; and TRT2, basal diet + 0.2% MPC. On days 35 and 70, there was a significant linear increase (P<0.05) in body weight, and the ATTD of dry matter, nitrogen, and Lactobacillus counts, and a significant linear decrease (P<0.05) in excreta ammonia emission with increasing MPC in the diets. During days 0 to 35, average daily gain and gain to feed ratio showed a linear increase (P<0.05) with increasing MPC, while serum creatinine concentration showed a linear decrease (P<0.05) on days 35. On days 70, drip loss decreased linearly with MPC in diets on day 7, while loin muscle area was linearly increased (P<0.05). During the overall period, there was a significant linear increase (P<0.05) in average daily gain and gain to feed ratio with increasing MPC in diets. In conclusion, dietary MPC supplementation has beneficial effects on growth performance, nutrient digestibility, fecal microbial shedding, meat quality, noxious gas emissions, and blood parameters in finishing pigs.

本研究的目的是确定日粮中添加多种菌株的益生菌和板栗栗壳提取物（MPC）的组合对生长性能，营养消化率，粪便微生物脱落，肉质，有害气体排放和血液参数的影响。整理猪。在为期10周的饲养试验中，总共使用了150头猪。饮食治疗组如下：CON，基础饮食；TRT1，基础饮食+ 0.1％MPC；和TRT2，基础饮食+ 0.2％MPC。在第35天和第70天，体重显着线性增加（P <0.05），干物质，氮和乳酸杆菌计数的ATTD显着线性下降（P饮食中MPC升高时排泄物中的氨排放量<0.05）。在0至35天期间，平均每日增重和饲料比随MPC呈线性增加（P <0.05），而血清肌酐浓度在35天呈线性下降（P <0.05）。在70天时，滴水减少饮食中，MPC在第7天呈线性下降，而腰部肌肉面积呈线性上升（P <0.05）。在整个期间，线性增长显着（P饲料中MPC的增加，平均日增重和饲料与饲料的比例<0.05。总之，日粮MPC补充剂对肥育猪的生长性能，养分消化率，粪便微生物脱落，肉质，有害气体排放和血液参数具有有益作用。
