Journal ArticleDOI
Effect of supplementation of prebiotic mannan-oligosaccharides and probiotic mixture on growth performance of broilers subjected to chronic heat stress
Muhammad Umar Sohail,Muhammad Umar Sohail,Michael E. Hume,James A. Byrd,David J. Nisbet,A. Ijaz,Aaqib Sohail,Muhammad Zubair Shabbir,Habib Ur Rehman +8 more
TL;DR: The results showed that chronic HS reduces broiler production performance, intestinal microarchitecture, and increases adrenal hormone concentrations, and supplementation of the MOS prebiotic and the PM can partially lessen these changes.
Journal ArticleDOI
Evaluation of bacterial diversity in the rumen and feces of cattle fed different levels of dried distillers grains plus solubles using bacterial tag-encoded FLX amplicon pyrosequencing.
Todd R. Callaway,Scot E. Dowd,Tom S. Edrington,Robin C. Anderson,Nathan A. Krueger,N. Bauer,Paul J. Kononoff,David J. Nisbet +7 more
TL;DR: In this article, a new molecular method, bacterial tag-encoded FLX amplicon pyrosequencing (bTEFAP) was used to perform diversity analyses of gastrointestinal bacterial populations.
Journal ArticleDOI
Diet, Escherichia coli O157:H7, and cattle: a review after 10 years.
TL;DR: Data from researchers across North America indicate that diet does impact STEC/EHEC populations in cattle prior to slaughter; however the economic, logistic and practical impacts of dietary changes must be examined and accounted for.
Journal ArticleDOI
Probiotics, prebiotics and competitive exclusion for prophylaxis against bacterial disease.
Todd R. Callaway,Tom S. Edrington,Robin C. Anderson,Roger B. Harvey,Kenneth J. Genovese,C. N. Kennedy,D. W. Venn,David J. Nisbet +7 more
TL;DR: The ecology behind the efficacy of probiotics, prebiotics and competitive exclusion cultures against pathogens found in food animals, including those that enter the food chain and impact human consumers is explored.
Journal ArticleDOI
Foodborne Campylobacter: Infections, Metabolism, Pathogenesis and Reservoirs
Sharon V. R. Epps,Roger B. Harvey,Michael E. Hume,Timothy D. Phillips,Robin C. Anderson,David J. Nisbet +5 more
TL;DR: The historical and emerging importance of this bacterial group is reviewed and aspects of the human infections they cause, their metabolism and pathogenesis, and their natural reservoirs are addressed in order to address the need for appropriate food safety regulations and interventions.
