Nutri-Lyse Lysozyme is known to eliminate intestinal pathogens in poultry and improve their growth performance. Lysozyme is 1, 4-β-N-acetylmuramidase. This enzyme cleaves the glycosidic bond between the N-acetylmuramic acid and N-acetyl glucosamine in Gram-positive bacterial peptidoglycan of the cell wall [9]. Lysozyme, a common enzyme, is commercially extracted from avian egg white and is widespread in many tissues and secretions of animals [10]. Some studies have reported significant function of lysozyme in various organisms as a barrier against potential pathogenic bacteria [11, 12]. Lysozymes play a role as an antibacterial agent, which is mediated through its direct bacteriolytic action or by stimulating macrophage phagocytic function. Vitamin E is required for growth and reproduction, it helps to maintain the structural tissue integrity, it supports development of the nervous system and contributes to disease resistance.
