LYZ and infection due to clostridium perfringens: In this study, the improvement in intestinal integrity score between LTG vs. LFG was a direct result of lysozyme treatment (p ≤ 0.05) as recorded previously by Du and Guo48 who proved that lysozyme or essential oils decreased the mortality, improved the intestinal integrity, alleviated the gut lesions, and significantly reduced the ileal concentration of sialic acid and the Mucin2 mRNA expression following C. perfringens infection in chickens.
