Feeding value in broiler chicken diets of a potato expressing a β-glucanase gene from Fibrobacter succinogenes

Abstract

Including a transgenic potato cultivar as a source of β-glucanase in CDC Silky barley-based diets for broiler chickens at 0.6 kg t-1 improved (P < 0.05) feed conversion by 8.8%; at 1.2 kg t-1 it reduced (P < 0.05) ileal digesta viscosity by 42%. With improved level and/or activity of expression, transformed potato may have potential as an enzyme additive.
