Abstract

Heal and total tract digestibilities of dietary components and energy in eight oat diets varying in chemical composition were studied with growing pigs in two 4×4 Latin square experiments. The diet with partially dehulled oats had the significantly (P < 0.05) highest ileal and total tract digestibility of organic matter, crude protein, total fibre and energy. The metabolizable energy value of the oat batches tested varied between 15.4 and 10.9 MJ kg‐1 dry matter. Significant correlations (P < 0.05) were found between both total tract and ileal digestibilities of organic matter and energy, respectively, and the content of fibre components, starch, crude fat and nitrogen‐free extractives. Differences in the correlations as predictors between the content of crude fibre, total fibre, neutral detergent fibre or acid detergent fibre and the ileal and total tract digestibility of organic matter and energy, respectively, were limited.
