Fig. 3From: A systematic review and meta-analysis of dietary fat effects on reproductive performance of sows and growth performance of pigletsForest plot showing effects of adding fat to diets during late gestation and lactation on litter weight (kg). Figure lists treatments in studies with treatment No. (Study), treatment group of fat-treatment or un-supplemented control (Experimental vs. Control), total observations (Total), mean of the treatment and standard deviation (Mean, SD), standardized mean difference (SMD), 95% confidence interval (95%-CI) and the weight accounting for the total statistics (weight). Test results for heterogeneity and overall fat supplementation effect are listed at lower left of each figure. P ≤ 0.10 was considered significant; 0.1 < P < 0.15 was considered a trend. A, Effect of adding fat on litter weight (at birth); B, Effect of adding fat on litter weight (at wean); C, Effect of adding fat on smaller litter weight than average (at birth).Back to article page
