Mutual Supplementary Effect of Proteins of Plant and Animal Origins of Broiler Rations

The lncreased interest in studing the effect of supprementary poultry diets with suitable levels and sources of animal protein mixtures had red to the present accepted practice of raising the biologial value of combined proteins from plant and animal origins. Therefore, the aim of the present work was urqflntly needed to study the effect of using different animal protein and yeast supplements of single protein.
