The current study evaluated the influence of the treatment with tea tree oil and cefepime on morpho- genetic, histo-immunohistochemical, and biochemical assessments in rats experimentally challenged with Escherichia coli ATCC 4157™. Thirty adult male rats were divided into control, E. coli infected positive group (1×108CFU/I/P/once), E.

Early nutritional management approach greatly impacts broilers' performance and resistance against coccidiosis. The current study explored the impact of post-hatch feeding with a combination of glutamine (Glut) and different levels of omega-3 on broiler chickens' growth performance, muscle building, intestinal barrier, antioxidant ability and protection against avian coccidiosis. A total of six hundred Cobb 500 was divided into six groups: first group (fed basal diet and unchallenged (control) and challenged (negative control, NC) groups were fed a basal diet without additives, and the other groups were infected with and supplemented with 1.

The commonly applied IBV vaccination protocols in broilers include alternatives to classic and/or variant attenuated live virus vaccines.
Aim: The current study targeted to assess the protective efficacy of concurrent and successive Ma5 and 4/91 vaccine strain regimens against the field variant II IBV strain (IBV-EGY-ZU/Ck-127/2021) in chickens.
