Feeding Fish Oil and Linseed Oil to Laying Hens to Increase the n-3 PUFA of Egg Yolk

Popis výsledku v původním jazyce

The research was carried out to assess the possibility of egg yolk enrichment through supplementation of fish oil (FO) and linseed oil (LO) to layer diet. A total of 84 ISA Brown laying hens were divided into three groups. Each group consisted of seven cages with four hens per cage. Groups received feed mixtures differing in combinations of oils. Mixture fed to the E1 group contained 1.50% LO and 3.5% FO, the E2 group had diets with 2.5% LO and 2.5% FO, and the E3 group was fed diets with 3.5% LO and 1.5% FO. Egg yolk content of ?-linolenic acid (?-LNA) and omega-3 polyunsaturated fatty acids (n-3 PUFA) in total fatty acids was increased (P < 0.001) due to increased content of linseed oil in hen diet and it was the most favorable in the E3 group. In groups E1, E2 and E3, the ?-LNA content was 3.25%, 4.33% and 5.18%, respectively, and the n-3 PUFA content was 6.80%, 7.22% and 8.50%, respectively. The content of eicosapentaenoic acid was higher (P < 0.05) in egg yolks of the E1 grou
