Application of a β-mannanase enzyme in diets with a reduced net energy content in post-weaning piglets resulted in equal performance and an additional economic benefit

β-Mannans are strongly anti-nutritive polysaccharide fibers found in most vegetable feed ingredients. The estimated content of soluble β-mannans common swine diets range from 0.15 to 0.40%. In vitro studies have demonstrated that as little 0.05% β-mannan can elicit a strong innate immune response. Hemicell HT (Elanco Animal Health) is β-mannanase enzyme for animal breaks down β-mannans, thereby preventing economic losses the wasteful response β-mannans. present study aimed compare pig performance on control diet and reformulated with lower energy – 45 kcal/kg NE reduction inclusion enzyme. A six-week feeding trial was conducted commercial post-weaning facility DanBred x Belgian Piétrain pigs starting at 21 days age. Standard three-phase were compared an kcal NE/kg (Hemicell HT; Elanco) 300 g/tonne. production data collected. analyzed using JMP 15.0 statistical program. Overall, did not differ significantly between groups both Phase 1 2, overall, during entire period. Mortality only numerically, but higher Control group. had overall benefit € 1.69 per piglet 15.18 tonne due reduction. current (45 NE/kg) able retain post-weaned piglets benefit.
