Fig. 7

Forest plot showing effects of adding fat to diets during late gestation and lactation on survival rate (%) of piglets from birth to weaning. 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). ADG, average daily gain. 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 number of survival rate of piglets (total); B, Effect of adding fat in sow diets on survival rate of piglets when survival rates were less than 80%.
