Combined supplementation of organic acid blend and hydrolyzed yeast mixture increases growth performance and tibia bone strength in broilers

摘要

This study investigates the effects of hydrolyzed yeast mixture (HYM) and an organic acid blend (OAB) supplementation individually and in combination on growth performance and tibia bone characteristics of broilers. A total number of 128 one day- old chicks were divided into four different groups with each group having 4 replicates in a trial of 35 days. The first group was kept as control whereas, the second and third groups were given HYM and OAB respectively. The fourth group (HYM+OAB) was given combination of HYM and OAB. At the end of trial, two birds from each replicate were slaughtered for analysis. Results revealed that feed conversion ratio and live body weight were significantly higher in HYM+OAB compared to other groups. Tibial bone analysis revealed that robusticity and tibiotarsal indices were significantly better for HYM+OAB. It is concluded that compared to individual, combined supplementation of HYM and OAB is more beneficial in broilers.
