The Impact of Inclusion of Fermented Feed with Probiotic Yeast on Performance,Intestinal Histology and Intestinal Microbiota of Broilers

This study aims to examine the effect of fermented feed flour (FFF) with probiotic Saccharomyces sp.(Sc) on performance, histology and intestinal microflora of broilers.The process of making fermented feed, namely, as much as 1% of Saccharomyces sp.yeast (108cfu/g) was mixed into commercial feed, then 5% molasses solution was added to the feed mixture until the water content was 35%.The mixture was then put into a basket made of bamboo and tightly closed.Then, it was incubated at room temperature (27C) for 3 days.After 3 days, it was dried in the sun for 2 days.Before feeding, the basic feed (commercial ration) was first mixed with TPFSc and stirred until homogeneous.Broilers in Group 1 (n = 60) served as healthy controls and were fed a basic diet without the addition TPFSc.Broilers in Groups 2, 3, and 4 were fed with the addition of 5, 10, and 15% FFFSc per kg of feed.The results showed that growth, feed efficiency, villus height (VH), and the number of lactic acid bacteria in broiler Groups 2 and 3 experienced an increase (P<0.05), while the population of Coliform and Escherichia coli in the intestine was decreased (P<0.05).It was concluded that the addition of 10 and 15% FFFSc to commercial feed can increase growth, feed efficiency, villus height, and lactic acid bacteria population, and can reduce the pathogen population in the broiler intestine.
