The effect of essential plant oils on mineral composition of egg mass and blood parameters of laying hens

Abstract

The aim of study was to analyze the dietary effect of pumpkin and flaxseed oils on mineral composition of egg mass and blood parameters of laying hens. At 38 weeks of age, Lohmann Brown Lite hens were housed in three-floor cages, divided into three dietary groups (C-control, E1-pumpkin oil (3%), E2-flaxseed oil (3%)). There were housed six hens in one cage. A total 18 hens were monitored. In the control group hens were fed with standard complete feed mixture for laying hens and in the experimental groups by feed mixtures with supplementation of pumpkin or flaxseed oils. Vitamin E was added into feed mixture in the experimental groups. The experiment lasted 52 days. Twelve eggs from each dietary treatment were randomly selected and analyzed. As regards the mineral composition of eggs, only concentrations of calcium after both oil supplementations and zinc after flaxseed oil supplementation in diet were significantly (P0.05) influence on enzymatic and protein profile.
