摘要: Abstract The objective of this meta-analysis was to assess effects probiotics on the growth performance pigs (Average Daily Gain (ADG) and Feed Efficiency (FE)). Data bases ( i.e. PubMed, ScienceDirect, Scopus) were searched from 1980 2015 unrestricted by language. inclusion criteria were: randomised controlled experiments using without apparent disease published in peer reviewed journals. Sixty-seven 60 included probiotic ADG FE, respectively. LAB supplementation increased (difference mean (DM) = 29.930 g/day, 95% confidence interval (CI) 17.617–42.261) improve feed efficiency (DM = −0.096 kg feed/kg body weight, 95%CI −0.120–0.071), considering source heterogeneity. There no evidence publication biases. showed that application during first stage pig grown finishing period resulted greater FE. effect not related use mono-strain or multi-strain probiotics, although it may depend strain used. breeds (especially F1 three-breed-rotational crossbreeding) characteristic these (maternal breeds) had an impact outcomes. These results might be used define guidelines standardize experimental designs future trials include each covariate differences estimated sizes.
