Effect of increasing dietary isoacid levels on total tract and apparent ileal nutrient digestibility and fermentation products in growing pigs fed corn-soybean meal diets.

ABSTRACT:

Background

Isoacids are the product of branched-chain amino acid fermentation and are naturally produced in the hindgut by microbial fermentation. In ruminants, supplementation of isoacids as a feed additive improves fiber utilization, with a positive impact on animal productivity. However, information on how isoacids impact nutrient digestibility in swine is limited. The objective of this experiment was to determine the optimal inclusion level of an isoacid blend product based on apparent ileal digestibility (AID) and apparent total tract digestibility (ATTD) of nutrients and fermentation products in the ileal digesta and feces of growing pigs fed a corn-soybean meal diet.

Methods

Twelve ileal cannulated pigs (20.9 ± 0.6 kg) were used in a 5-period crossover design with 6 d
