EFFECT OF ORGANIC ACID AS A FEED SUPPLEMENT ON GROWTH PERFORMANCE OF BROILER

Abstract

An experiment was carried out to evaluate the effect of organic acid as a feed supplement on growth performance of broiler. The experiments were laid out in Completely Randomized Block design (CRD) with four treatments. The treatments were Control, 0.5% Propionic acid,1% Lactic acid,1% Citric acid. Each treatment was replicated thrice. It was revealed that the effect of organic acid on feed conversion ratio were 1.48,1.49,1.54 and 1.68 in these different treatments control, Propionic acid, Lactic acid and Citric acid respectively. The cumulative feed intake was found to be 3073.94gm, 2911.46gm, 3338.24gm and 3214.94gm in these different treatments control, Propionic acid, Lactic acid and Citric acid respectively. Similarly, water intake were found to be 356.79ml, 350.28ml, 400.97ml and 355.51ml in these different treatments control, Propionic acid, Lactic acid and Citric acid respectively. From the overall experiment, we observed that control feed gave less feed conversion ratio (FCR) though mortality rate was higher. The FCR was found to be less in propionic acid as comparison to other organic acids and the mortality rate was found to be lowest as well. Cumulative feed intake were highest in lactic acid treatment and lowest in propionic acid treatment and water intake were highest in lactic acid treatment and lowest in propionic acid treatment. So, we can conclude that the effect of lactic acid on water intake and feed intake were found to be better whereas the effect of propionic acid was found to be better on feed conversion ratio.
