Dietary supplementation of Echinacea purpurea powder improved performance, serum lipid profile, and yolk oxidative stability in laying hens
The present study aimed to investigate the effect of supplemental Echinacea purpurea (EP) powder on performance, serum metabolites, and yolk stability in laying hens. A total of 150 Hy-Line W-36 Leghorn laying hens, 43-wk of age, were randomly assigned into the five replicate cages for each of the f...

Zusammenfassung: | The present study aimed to investigate the effect of supplemental Echinacea purpurea (EP) powder on performance, serum metabolites, and yolk stability in laying hens. A total of 150 Hy-Line W-36 Leghorn laying hens, 43-wk of age, were randomly assigned into the five replicate cages for each of the five experimental diets based on a completely randomized design. Dietary treatments included different levels (0, 2.5, 5, 7.5, and 10 g/kg of diet) of EP powder, which were fed to the birds during a 70-d feeding trial. Results showed that dietary addition of EP powder caused significant (P |
