Effects of exogenous protease supplementation of diets containing animal proteins or not on Campylobacter jejuni colonization and on the intestinal microbiota of broiler chickens.

ABSTRACT:

Background

Campylobacter jejuni, commonly present in the intestinal tract of poultry, is a major causative agent of human gastroenteritis. To successfully colonize the chicken gut, C. jejuni needs to have access to certain amino acids. However, the amino acid profile and its availability in the gut is dependent on the type of ingested protein and its digestibility. Therefore, manipulating the digestibility of different protein sources, using an exogenous protease, may be a promising way to control Campylobacter colonization in chickens.

Results

Chickens were fed with an exclusive vegetarian protein source diet (veggy diet) or a diet also containing animal proteins (animal diet), with or without exogenous protease from one day of age. At 14 days of age, all chickens were inoc
