The Role of Feeding Type in Salmonella Spp. Transmission

Abstract

The infection with Salmonella in pigs farms is usually endemic and largely asymptomatic. The present study aimed the importance of feeding type (dry/wet) administered in the transmission of Salmonella in pigs farms. We had studied two farms, one in which pigs received wet feeding and at the other the given ration was dry. From each farm were collected 100 fecal and 50 feed samples. After analyzing the samples collected, it was found that the number of positive samples on the farm were the ration was liquid, was 34% from the feces and (2%) from the feed, which was reduced in comparison with the farm were the ration was dry, where the positive samples were (61%) for feces, and 4% from feed. The results support the ideas that liquid feeding ensures less chance of contamination by 27% compared to dry feeding, because is inducing an increases of organic acids which facilitates normal bacterial growth, leading to reduction of Salmonella.
