| Abstract: | To evaluate the effect of a probiotic culture in combination with dietary lactose as a prebiotic, 2 experiments were performed. Treated poults (Lactobacillus spp.-based probiotic culture) received dietary lactose (0.1%) continuously in the feed and probiotic culture (~106 cfu/mL) in the drinking water. Controls received no treatments. Three hundred twenty selected female poults were tagged and randomly divided in 2 treatments with 4 replicates each (n = 40). In experiment 1, poults were challenged with ~104 cfu of Salmonella Enteritidis; however, in experiment 2, no challenge was provided to poults. Body weight was evaluated on d 1, 7, and 14 (experiment 1, trial 1 and 2, experiment 2, trial 3) and on d 1, 8, and 18 (experiment 2, trial 4). Body weight and FCR were significantly (P < 0.05) improved by treatment in Salmonella-challenged poults (trials 1 and 2). In contrast, unchallenged turkey poults (trials 3 and 4) showed no difference (P > 0.05) in either BW or FCR. These data suggest that dietary lactose with appropriate probiotic organisms may enhance performance of poults following a mild pathogenic challenge. |
