Effects of using locally produced protein feed ingredients in low protein diets to single-phase-fed growing-finishing pigs

Åkerfeldt, Magdalena; Göransson, Leif

Abstract

In two trials, 358 female and entire male pigs vaccinated against boar taint (YxH) were single-phase-fed with diets that were planned to contain 0.78g standardized ileal digestible (SID) lysine/MJ net energy and 14.5g SID CP/g SID lysine. A reference diet with soya bean meal (SBM) as the protein feed ingredient, was replaced with either cereal by-products (CBP), rapeseed meal (RSM), faba beans (FB) or mixtures of 50% CBP and 50% RSM (CBP+RSM) or 50% FB and 50% RSM (FB+RSM) in the experimental diets. Treatments had no effect (P>0.05) on daily weight gain, feed efficiency, carcass weight, lean meat content or dressing percentage and carcass value. Single-phase-fed pigs on diets with local protein ingredients can perform as well as single-phase-fed pigs on diets with soya bean meal, and CBP, RSM, FB have the potential to replace soya bean meal in nutritionally well-balanced diets to growing-finishing pigs.
