The effect of introducing purified β-glucans to a wheat-based diet on total tract digestibility and gaseous manure emissions from pigs as compared with consumption of a β-glucan-rich, barley-based diet

In summary, the current study demonstrates that β-glucans may be added to a wheat-based diet without depressing nutrient digestibility as compared with a barley-based diet. Furthermore, manure odour from pigs offered a wheat-based diet containing β-glucans may be improved to levels comparable with a barley-based diet. However β-glucan supplementation was ineffectual at attenuating manure ammonia emissions comparable with consumption of a barley-based diet.
