Poultry meat is a valuable source of nutrients and the enrichment with health-promoting substances such as polyunsaturated fatty acids (n-3 PUFA) an important factor for consumers' choice. Camelina meal (Camelina sativa) animal feedstuff used to achieve this goal, but administration n-3 PUFA-enriched diets in broiler nutrition can accelerate oxidative processes leading decreased quality final product. The aim study was investigate effect organic Cr chromium picolinate (CrPic) on quality,...
