Abstract:

Enriched composition of broiler chicken meat, in comparison with commercial mass production, contains increased levels of ω–6 and ω–3 fatty acids and carotenoids complex, which positively influence human health and prevent risk factors that cause various diseases. The aim of the investigations was to evaluate the possibility of obtaining an enriched composition broiler chicken meat and to evaluate the expenses of production in bio-economic aspects by using vegetable oils that contain an increased amount of ω–6 and ω–3 fatty acids level and an additive of carotenoids complex “Karotinas V”. The feeding trial was carried out with cross ROSS 308 broiler chickens ranging in age from 1–42 days (n  = 300). It was concluded that the combination of oils in broiler chicken feed for producing enriched composition meat is 1.0% flax seed, 1.0% rapeseed and 2.0% soybean oils and 0.1% carotenoids complex. Use of the composition resulted in broiler chicken meat with 27.4% ω–6 and with 8.3% ω–3 fatty acids in total lipids, which is about 3.9% and 3.2 % higher than in the commercial product. Poultry organism metabolic processes are essential factors that determine the carryover levels of fatty acids and carotenoids from feed to meat, and it is impossible to precisely evaluate and calculate these physiological processes in organisms, economically. In the trial, the expense of feed consumption per 1,000 broiler chickens was higher than by using commercial feed but increased the broiler chickens’ live weight, providing a possible 15% increase in total sales revenues for 1,000 broiler chickens. The tested combination of oils resulted in increased levels of ω–6 and ω–3 fatty acids in broiler chickens’ tissue: as a result, income was higher in the experimental group.
