Abstract
Post-weaning diarrhoea (PWD) reduces production efficiency through increased morbidity and mortality and poorer efficiency of growth (Halas et al., 2007). Dietary proteins that are not digested and absorbed in the small intestine are fermented by the intestinal microbiota to produce a number of potentially toxic epithelial irritants such as ammonia, which are thought to increase the incidence of PWD. Limiting the amount of protein available for microbial fermentation has been proposed as a strategy to reduce the risk of PWD in weaner pigs without using in-feed antibiotics (Halas et al., 2007). In this experiment, we hypothesised that feeding a lower protein diet for a short period of time after weaning would reduce PWD by reducing the amount of protein entering the hindgut from the small intestine, thereby reducing protein fermentation in the colon.
