Influence of Feed Additives to Enterococci in Chickens Gastrointestinal Tract

Abstract

The present study was undertaken to provide detailed information about the effect of different feed additives on the enterococci colonization of chicken gastrointestinal tract. The Agolin Poultry, Agolin Tannin Plus, Biostrong 510+FortiBac and Agolin acid were administered to forth feed mixtures and Biocitro to drinking water in various amounts except of the control group. The addition of 1.5 g Agolin Poultry to 15 kg of feed was included in the first experimental group, the addition of 7.5 g Agolin Tannin Plus to 15 kg of feed in the second experimental group, the addition of 15g Biostrong510+FortiBac to 15 kg of feed the third experimental group, 15 g in the fourth experimental group of Agolin acid to 15 kg of feed and 10 ml fifth experimental group of drinking water. The lowest count of enterococci counts was found in the control group. The highest count of enterococci counts was found in the second experimental group where 7.5 g of Agolin Tannin Plus to 15 kg was added to feed mixture. For the identification of eterococci species the molecular method was used
