Abstract

Activation of the innate immune system after weaning leading to inflammation of the gastrointestinal tract (GIT) has been linked to compromised GIT barrier function, increased risk of enteric disorders, and poorer performance (Gallois et al. 2009). To counteract these effects, the dietary requirement for some amino acids such as tryptophan (Trp) and (or) sulphur amino acids (SAA) may increase. The present experiment tested the hypothesis that additional dietary Trp and (or) SAA would improve growth performance and ameliorate indicators of inflammation in weaner pigs experimentally infected with Escherichia coli.
