Title: Alternative feedstuffs for reducing ammonia and odor emissions in pork production systems and improving the pig‟s gut health – NPB #06-117

Nutrition can help reduce the impact of pork production on the environment and improve pig gut health. The formulation of diets based on highly-digestible feedstuffs and which meet the exact requirements of the pigs, markedly reduces the excretion of minerals such as nitrogen and phosphorus into the environment. The presence of fermentable dietary fiber in the diet can also decrease the emission of gaseous nitrogenous compounds by shifting nitrogen excretion from urine to feces. It is also hypothesized that fermentable dietary fiber can improve gut health by favoring the development of health-promoting bacteria such as Lactobacilli, at the expense of pathogenic ones.
