Abstract

The metabolized substance was produced in the laboratory (postbiotics), according to three successive stages. The first stage included: isolating and identifying lactic acid bacteria from the ileum area in the small intestine of poultry, while the second stage included: activating the isolated bacteria on sterilized sorted milk media for three consecutive times. The third stage included: producing the biologically metabolized substance or biologically active compounds, in the form of a fine powder. This substance was added to the diets of broilers at a level of (0, 1, and 2) g /kg feed, for three experimental treatments, T₀, T₁, and T₂, respectively, during the rearing period of 35 days. To study its effect on the productive traits and economic efficiency of broilers. The results of the statistical analysis showed: a significant improvement (P≤0.05) in the rates of body weight and weight gain, in addition to a significant improvement (P≤0.05) in the food conversion rate and in the economic efficiency measure in favor of the postbiotics T₁ and T₂ treatments compared to the control treatment. T₀, while there are no significant differences in the rate of feed consumption between all the treatments studied.
