Effect of dietary organic acids supplementation on growth performance, nutrient digestibility, and gut morphology in weaned pigs

This study was conducted to investigate the effects of dietary supplementation with different organic acid (OA) mixtures on growth performance, nutrient digestibility, and gut morphology in weaned pigs. A total 56 pigs (7.93 ± 1.04 kg body weight) were assigned four treatments seven replicates per treatment for a 35-day over two phases: phase 1 (day 14) 2 14 35). Diets consisted (1) corn–soybean meal basal diet without any additive (negative control, NC); (2) NC + formic propionic acids (TRT1); (3) butyric, formic, (TRT2); (4) antibiotic (positive PC). During overall period, gain feed ratio fed PC TRT1 diets tended be higher (P = 0.059) than that those diet. However, OA had no digestibility.
