Combined supplementation of organic acid blend and mannanoligosaccharide suppresses expression of heat shock protein 70 in broilers

This study investigates the effects of mannanoligosaccharide (MOS) and organic acid blend (OAB) supplementation individually and in combination on small intestinal microbiota and expression of heat shock protein 70 in Hubbard chicks. 128 day-old birds 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 MOS and OAB respectively. The fourth group (MOS+OAB) was given combination of MOS and OAB. At the end of trial, two birds from each replicate were slaughtered. The number of lactic acid bacteria and yeast were significantly higher in MOS+ OAB birds compared to other groups. Expression of heat shock protein 70 significantly decreased by MOS and OAB individually and in combination. It is concluded that combined supplementation of MOS and OAB is beneficial in broilers.
