Hens’ eggs represent a rich source of important nutrients, including lipids and carotenoids. Lipid composition of hens’ eggs is influenced by genetic factors, age, and diet. Lipids of egg yolk represent an important source of animal fat for humans. Carotenoids are the pigments of egg yolk, and their concentration is an important attribute, since the consumers associate an intense colour with eggs that are both healthier and of higher quality. Since carotenoids are not produced by animals, their level in animal products, including egg yolk, is related strictly to diet. They play numerous physiological roles in both the laying hen and developing embryo. Analyzed eggs, both fresh and stored for 30 days at temperatures below 12°C, were obtained from hens fed with the same type of forage. The study was conducted in January and February, and the parameters analyzed were egg lycopene and

Metronidazole acts by preventing anaerobic microbial cell’s production of hydrogen ions, while oxytetracycline, synthesis tetracycline, has only broad-spectrum bacteriostatic action. These active substances are used in compounded drug formulations for treatment of several forms of ornamental birds’ enteropathies. As a consequence, the present study aims to assess the hematological and biochemical profile of ornamental birds under Enteroguard Madministration, a pharmaceutical product based on metronidazole and oxytetracycline. The investigations consisted of hematological and biochemical testing of 3 groups of healthy ornamental hens, yellow Orpington breed, aged between 1 and 3 years. The evolution of investigated parameters showed insignificant differences between different lots of tested birds, that have shown a haematological- biochemical profile corresponding to a good level of health and welfare throughout the observation period, pre- and post-treatment.
