Effects of increased content of organic selenium in feed on the selenium content and fatty acid profile in broiler breast muscle

摘要: The aim of this study was to determine the effects organic selenium supplemented broiler feed on content and fatty acid profile in breast muscle tissue. carried out 60 male Ross 308 broilers that were slaughtered at age 42 days. After day 21, divided into three experimental groups (P1, P2, P3), each group given separately prepared finisher diets contained 18% crude protein 14.67 MJ/kg ME (finisher diet 6% oil, which 3% sunflower linseed oil added for purpose increase portion α-linolenic acid. (Sel-Plex®) as follows: no selenium, 0.3 mg Se/kg 0.5mg P1, P2 P3 group, respectively. It determined had a significantly higher (P < 0.05) (0.256 tissue) than (0.183 P1 (0.087 tissue). Supplementation amount mg/kg affected tissue by increasing portions α-linolenic, eicosapentaenoic, docosapentaenoic docosahexaenoic acids total n3 polyunsaturated acids, lowering saturated monounsaturated acids. nutrition, poultry, composition, Poultry production Croatia has long tradition. In 2008, yearly consumption fresh meat 44.68 kg per household member. most consumed poultry (16.96 kg), followed pork (15.51 beef (9.05 kg); other animals less consumed. Popularity can be justified fact it is satisfactory nutritive quality, not expensive meets organoleptic demands consumers. Grains are basic forage feed, additional fats, mostly rich n-6 (PUFA) metabolic energy (ME) balancing. produced low content; therefore important supplement microelement feed. investigate increased (containing oil)
