The research was aimed at determining the influence of supplementing turkey hens complete feed with synthetic antioxidants on the performance, carcass yield and blood biochemical
parameters. The experiment was conducted on 120 turkey hens Big-6. From 6 to 16 weeks of life the birds had free access to feed and water. Group I (control) was fed a complete mixture. Birds from group II received a complete feed supplemented with antioxidant L100 (BHT, propyl gallate, etoxyquin, citric acid). Feed intake, body weight of the birds and their mortality during transportation as well as WEO were noted. In blood samples (taken at the end of the 9, 13 and 16 weeks of birds life), the content of TP, GLU, CHOL, HDL and LDL-chol. and TG was determined. At the end of the trial, the birds were slaughtered and a simplified dissection was carried out. Dressing percentage, content of breast meat in the carcass, content of leg meat, leaf fat as well as giblets, were calculated. The synthetic antioxidants mixture supplement resulted in no substantial increase in performance. The results of blood analyses showed, however, that the supplement of synthetic antioxidants mixture improved indicators of the lipid profile in turkey hens’ blood.
