Digestibility of amino acids in organically cultivated white-flowering faba bean and cake from cold-pressed rapeseed, linseed and hemp seed in growing pigs

Abstract

The study aimed at determining the ileal apparent (IAD) and standardised ileal (SID) digestibility of crude protein (CP) and amino acids (AA) in organically cultivated white-flowering faba beans (Vicia faba), and cakes from hemp seed (Cannabis sativa), linseed (Linum usitatissimum) and rapeseed (Brassica napus). The experiment was designed as a four period cross-over trial with six castrated male Yorkshire pigs fitted with post valve T-caecum (PVTC) cannulas. The IAD and SID of CP for the feed ingredients ranged from 79.2-85.9% and were affected by dietary treatment, with significantly lower values in rapeseed cake. The IAD and SID of most AA in the feed ingredients were also significantly affected by dietary treatment, but without any consistent trend. However, the overall digestibilities were in general comparable with conventional protein feed ingredients. Thus, these alternative protein feed ingredients have the potential to be used to a greater extent when formulating organic pig diets.
