Effect of the Interaction Between the Level of Water Dilution, Fermentation Time of Chicken Feed, and the Level of Addition of the Iraqi Biostimulant on the Microbial Count of Bacillus subtilis and Saccharomyces cerevisiae

Abstract

This study aimed to demonstrate the effect of using feed fermented with Iraqi probiotic and water on chicken feed and to study the effect of fermentation on the microbial count of Lactobacilli and Bifidobacterium bacteria. Four concentrations of Iraqi probiotic were added: 2.5, 5.0, 7.5, and 10/kg feed. The feed was diluted with water at ratios of 0.5, 1.0, and 1.5 liters of water/kg feed. The feed was placed in an incubator at 37°C for different periods: 24, 48, and 72 hours. The goal of the experiment was to select the best concentration of Iraqi probiotic , along with the best water addition and the most appropriate fermentation time. All fermentation treatments resulted, There was a significant increase (P≤0.05) in the logarithmic numbers of all types of bacteria and yeast, and the best results were in favor of the 100% fermented feed prepared with a concentration of 10 g of probiotic/kg feed, diluted with water at a rate of 1 liter of water/kg feed, and fermented for 48 hours compared to the rest of the treatments.
