Effect of feeding of 5% prefermented cereal-based bioproduct enriched with γ-linolenic acid on production indicators, chemical composition, fatty acid profile and lipid oxidation of broiler meat
The aim of this work was to study the effect of the addition of prefermented cereal-based bioproduct (5%; BP) enriched with γ-linolenic acid to the commercial feed for broiler chickens on the production indicators, chemical composition, fatty acid profile and lipid oxidation of the meat. BP was prep...
