Reduction of Salmonella typhimurium concentration in broiler chickens by milk or whey.
Whey (5%) in the feed of chicks for the first 10 days of life reduced the mean log10 number of viable S. typhimurium from 5.68 in control chickens to 3.38 in whey-fed chickens. Lactose in drinking water or reconstituted dry milk (5% wt: vol) in drinking water reduced the mean log10 number of S. typhimurium to 2.60 and 2.11, respectively. Milk (5% wt: wt) in feed was not effective in reducing S. typhimurium colonization. The lack of effect of milk in the feed is believed to be because not enough lactose was provided at the 5% (wt: wt) concentration. Lactose in whey or nonfat dried milk offers alternatives to the use of pure lactose in preventing or lowering S. typhimurium numbers in young broiler chickens.
