Technical Abstract: Previous research has demonstrated that broiler breeders fed cottonseed meal had significant reductions in Campylobacter when compared to soybean meal fed controls. In the present experiment, three studies were conducted to evaluate the effect of dietary cottonseed meal or gossypol on the incidence of Campylobacter colonization in broilers. In the first study, an in vitro fermentation using cecal contents from six-week-old broilers were combined with gossypol (4 ug/mL) and challenged with either Campylobacter jejuni (10**4 cfu/mL) or Salmonella Typhimurium (ST; 10**4 cfu/mL) and evaluated for the presence of these bacteria at 1, 3, 5, or 18 hours after challenge. Campylobacter incidence was significantly reduced but Salmonella incidence was unaffected in the gossypol treated contents one h after exposure when compared to the controls. In the second study, day-of-hatch broiler chicks were fed 0, 300, or 600 mg/kg of gossypol for 10 days and challenged with ST at d 3. The incidences in cecal Salmonella concentrations were not significantly different in broilers fed gossypol when compared to the controls. In a third study, market-age-broilers were fed a diet containing either a corn-soybean control, 20% cottonseed meal, 5% cottonseed hulls, or 5% whole cottonseeds for 12 weeks to evaluate the effects on Campylobacter cecal colonization. Broilers fed each diet became Campylobacter positive after one week and remained positive until termination of the experiment. The results of the present study suggest that broilers fed cottonseed or cottonseed products were not protected from Salmonella or Campylobacter colonization.
