Researchers at the Department of Animal Sciences from Georg-August-University in Göttingen in Germany conducted a study on the effects of four types of litter material on the frequency of salmonella in broilers, finding that wood shavings showed the highest prevalence.
Four different materials — peat, chopped straw, woods shavings and silage — were tested. With three samples out of six samples being positive, wood shavings showed the highest salmonella prevalence, followed by peat with two positive results. Corn silage was found to be a suitable alternative for common litter materials and revealed only one positive sample. Chopped straw was found to be free of salmonella in the study; however, it had a higher risk for negative side effects concerning animal health and house climate.
