Abstract
The objective of this study was to determine the effectiveness of different doses of dried yeast Yarrowia lipolytica in feed mixtures for turkey hens based on the evaluation of their production effects and changes of haematological indices of blood. The experiment was carried out on 240 turkey hens of Big 6 line, aged from 1 up to 16 weeks. The birds were assigned to three groups, 80 turkeys each. Turkey hens from group I did not receive any additive to their feed mixtures, while the birds from groups II and III received a compound feed with 3 and 6% share of dried yeast Yarrowia lipolytica. In the 15th week of turkey hens rearing, their blood was sampled and hematological parameters were established(the number of WBC and RBC, Ht value and Hb concentration). After the rearing, the birds were slaughtered, and their carcasses were subjected to slaughter analysis. The obtained results indicate that the application of the additive dried yeast Yarrowia lipolytica in a dose of 3% positively influenced the evaluation of slaughter carcasses of turkey hens and changes of hematological indices of blood.
