At 240 h, manure from pigs offered the wheat-based diet+β-glucans had decreased concentrations of butyric acid (P = 0.033) and valeric acid (P = 0.021) compared with pigs offered the barley-based diet. Pigs offered the barley-based diet+enzyme composite had a decreased concentration of valeric acid (P = 0.027) compared with the barley-based diet.
Pigs offered the barley-based diet+enzyme composite had decreased manure odour emissions (P = 0.030) compared with the barley-based diet. Pigs offered the wheat-based diets+β-glucans+enzyme composite had decreased odour emissions (P = 0.035) compared with the wheat-based diet+β-glucans. Pigs offered the wheat-based diet+β-glucans had increased
manure ammonia emissions (P = 0.042) from 0 to 240 h compared with pigs offered the barley-based diet. Pigs offered the barley-based diet+enzyme composite had
increased manure ammonia emissions from 0 to 96 h (P = 0.014) and from 0 to 240 h (P = 0.023) compared with pigs offered
the B diet
