Abstract :

Abstract: This study was conducted to evaluate the effect of a probiotic mixture and chromium as food supplementation on broiler chicks’ performance. The experiment was conducted, to determine the effect of a probiotic mixture (BiovetYC) and chromium chloride supplementation on growth performance, carcass traits and immune response against Avian Influenza virus from 0- to 42-d-old broiler chicks as well as to determine the anti -stress effect of the dietary probiotic mixture and chromium chloride supplementation on broiler chicks (0-42days old) when subjected to high stocking density (15 birds/m2 in open-system) as a stress factor. Growth performance, carcass traits and Avian Influenza immune response were recorded.
At 42-d of age, 50 birds were randomly selected from each group for blood samples collection and slaughtered for carcass traits. Stress indicators in blood (cortisol and L/H ratio) were measured. The current results revealed: (1) The activation effect of the probiotic mixture on growth performance (2) Chromium chloride supplementation improves growth performance, carcass traits, and immune response and had a strong anti -stress effect.
