摘要

试验选用初始体重为23.58±0.8 kg的杜×长×大生长猪180头。根据初始体重和性别,随机分配3个饲粮处理,每个处理12个重复(栏),每个栏5头猪。3种饲粮处理分别为基础饲粮(CON)和在基础饲粮中添加0.1%芽孢杆菌和酵母菌复合菌(BS1)或0.2%益生菌复合菌(BS2)。试验期42 d。结果表明:第42天,BS1组猪的体重显著高于CON组猪(P <0.05)。试验第21 ~ 42天,BS1和BS2饲粮的平均日增重(ADG)均高于CON饲粮;0.05),仅BS1组高于CON组。饲粮中添加益生菌复合物可降低第42天仔猪粪便中nh3和h2s的排放量。因此,在生长猪的后期日粮中添加0.1%的益生菌复合物,可以更有效地提高猪的体重和日增重,减少有害气体的排放。

Probiotic complex supplementation to growing pig’s diet enhances daily growth and reduces fecal gas emission
A total of 180 growing pigs (Duroc × Landrace × Yorkshire) with an initial body weight (BW) of 23.58 ± 0.8 kg were used in this experiment. According to initial BW and sex, pigs were randomly allotted three dietary treatments, 12 replicates (pen) per treatment, and five pigs per pen. The three dietary treatments were basal diet (CON) and basal diet supplemented with either 0.1% Bacillus and Saccharomyce s spp.-based probiotics complex (BS1) or 0.2% probiotics complex (BS2). The whole experiment lasted 42 days. The results showed that the BW of pigs fed the BS1 diet was significantly higher than those fed the CON diet on day 42 ( P < 0.05). The average daily gain (ADG) of pigs receiving BS1 and BS2 diets was higher than those fed CON diet during days 21–42, whereas during the overall experiment period ADG ( P < 0.05) was higher in only BS1 compared with CON group. The NH 3 and H 2 S emissions on day 42 were reduced from the feces of pigs fed probiotic complex-supplemented diets. Therefore, adding 0.1% probiotic complex to the late-phase diet of growing pigs can more effectively improve BW and daily gain and reduce harmful gas emissions.

期刊介绍: Published since 1957, this quarterly journal contains new research on all aspects of animal agriculture and animal products, including breeding and genetics; cellular and molecular biology; growth and development; meat science; modelling animal systems; physiology and endocrinology; ruminant nutrition; non-ruminant nutrition; and welfare, behaviour, and management. It also publishes reviews, letters to the editor, abstracts of technical papers presented at the annual meeting of the Canadian Society of Animal Science, and occasionally conference proceedings.
