Histological Picture of Parenchymal Organs of Quails When Adding Dry Biomass of Microalgae Chlorella Vulgaris to the Diet

Abstract

Modern high-tech industrial poultry farming, due to the numerous impacts of negative factors of the technogenic environment, often leads to a pronouncednegative impact on the bird's body. Prevention of possible consequences of the impact of negative factors on agricultural poultry is carried out by adding biologically active substances to the diet, which include succinic acid. We studied the effect of dry biomassы of Chlorella vulgaris microalgae in different doses on the histological picture of the liver, spleen, bursa, and heart in meat quails. For this purpose, 4 groups of birds with 50 heads each were formed. The first experimental group received daily dry biomass of Chlorella vulgaris microalgae at a dosage of 2 mg/kg of live weight, the second experimental group – 4 mg/kg of body weight, the third – 6 mg/kg of body weight. The control group received a basic diet. The duration of the experiment was 7 weeks. After 50 days, the poultry was also slaughtered for histological studies.  Studies have shown that отмечалась focal fattyliver dystrophy was observed in the control group, while no pathomorphological changes were noted in other organs. In all experimental groups, the histological picture of internal organs corresponded to the norm.
