Effect of anaerobic cecal microflora and dietary lactose on Salmonella colonization in bobwhite quail (Colinus virginianus).
The effect of oral inoculation with anaerobic cultures of cecal microflora from adult broiler chickens and dietary lactose on Salmonella typhimurium cecal colonization was evaluated in bobwhite quail chicks. One-day-old chicks were divided into four groups and provided 1) no anaerobic cultures, no lactose (control); 2) anaerobic cultures; 3) 2.5% lactose (wt/vol) in drinking water; or 4) anaerobic cultures and lactose. All groups were challenged orally with 10(4) S. typhimurium at 2 days of age. Salmonella growth in the cecal contents was significantly decreased (P < .05) at 15 days of age in each of the three treatment groups as compared with controls. Protection against Salmonella colonization was highest in the treatment group provided anaerobic cultures only. The results indicated that cecal flora from adult chickens enhances Salmonella colonization resistance in quail chicks.
