Gut Health of Pigs: Challenge Models and Response Criteria with a Critical Analysis of the Effectiveness of Selected Feed Additives — A Review by Adewole, D. I., Kim, I. H., and C. M. Nyachoti 2016 Asian-Australasian Journal of Animal Sciences Jul: 909–924
In Significant Impact Groups: Feed / gut health \ Feed additives and supplements
Species targeted: Pigs;
Age: Not stated;
To improve productivity of pigs, researchers have evaluated a wide range of feed additives (such as immunoglobulin, omega 3 fatty acids, yeast derived B glucans, organic and inorganic acids, high levels of zinc oxide, essential oils, herbs and spices, some types of prebiotics, bacteriophages and anti-microbial peptides, probiotics, glutamine, threonine, cysteine, and nucleotides) as substitute products for antibiotics. One approach to evaluate the effectiveness of these additives in vivo is to use an appropriate disease challenge model. Over the years, researchers have used a number of challenge models which include the use of specific strains of enterotoxigenic Escherichia coli, bacteria lipopolysaccharide challenge, oral challenge with Salmonella enteric serotype Typhimurium, sanitation challenge, and Lawsonia intercellularis challenge. These challenge models together with the criteria used to evaluate the responses of the animals to them are also discussed in this review.
