Role of trefoil factors in maintaining gut health in food animals.

It is imperative to preserve the integrity of the gastrointestinal system in spite of the persistent existence of harmful chemicals and microbial flora in the gut. This is made possible by essential healing initiators called Trefoil factors which helps in mucosal reconstitution and tissue development on the gastrointestinal surface. The trefoil factors are a class of abundant secreted proteins that are essential for epithelial continuity (TFFs).

Characterization of spray-dried plasma-induced immune response in Salmonella-challenged broiler chicks.

Spray-dried plasma (SDP) is a functional feed additive that has been established to improve performance and health of livestock. Understanding the effect of SDP in immune response modulation is essential to optimize its use for controlling Salmonella Enteritidis (SE) infection in chickens. This study was conducted to determine the levels of expression of selected cytokine genes in the ileum and cecal tonsil of SE-challenged broiler chicks.

Supplementation of ginger root extract into broiler chicken diet: effects on growth performance and immunocompetence.

Ginger contains bioactive compounds that possess anti-inflammatory and antimicrobial properties. In this study, 432-day-old Ross 708 broiler male chicks were randomly allocated to 6 dietary treatments to investigate the effect of ginger root extract (GRE) on immunocompetence and growth performance to 6 wk of age. Treatment 1 (CON) consisted of chicks fed a corn-soybean meal (SBM), a base diet without GRE.

Comparative efficacy of spray-dried plasma and bacitracin methylene disalicylate in reducing cecal colonization by Salmonella Enteritidis in broiler chickens.

Spray-dried plasma (SDP) contains immunoglobulins and glycoproteins that possess antibacterial properties. Two floor-pen trials were conducted to determine the efficacy of dietary SDP and bacitracin methylene disalicylate (BMD) antibiotic in reducing intestinal colonization by Salmonella Enteritidis (SE) in broiler chickens. Experiment 1 was a 2-wk, 3 × 2 factorial design consisting of 6 treatments.
