ABSTRACT

Swine producers use feed additives because of most of the studies demonstrated their ability to
increase growth rate, improve feed utilization, and reduce mortality and morbidity in weaned pigs.
This study was undertaken to evaluate the effect of organic acid (Citric acid) as feed additive in
swine starter diet. One group of Large White Yorkshire piglets were fed with swine starter feed
supplemented with 2% citric acid and the other group was kept as control. The E.coli count was
found to reduce from 88x1010+4.301 cfu/ml during first week to 4.78x106+0.575 cfu/ml by 28 days
of weaning in the citric acid fed group with no mortality due to piglet scour. Hence it was concluded
that citric acid supplementation to starter diet in piglets before weaning had a positive effect in
reducing the E.coli count with improved weight gain and reduced mortality.
