Utilization of Brewer’s Spent Grains and Agricultural Residues in Pig Feed Formation

In this study, brewer’s spent grains (BSG)-raw matrix was technologically and functionally improved by adding natural active ingredient carriers (crushed wheat, rapeseed, pumpkin seed press cake) using planetary roller extrusion used as feed additive for pigs. Feeding trials were run 189 days 60 pigs with an age of 28 days. Pigs grouped in a control group (fed organic basic feed) two experimental groups BSG 1 or 2 addition to feed). The 20 animals per gained similar weight the (306 g day−1 725 day−1) fed (282 627 (250 598 during rearing fattening phases, respectively. Carcass evaluation revealed that meat quality did not differ between groups. BSG-based formulations tested seem result negative effects on gain nor quality. Animals generally good health marketable quality, thus outcomes study are expected contribute utilization strategy from breweries.
