Influence of Spirulina platensis biomass in compound feed composition on the dynamics of morphological parameters of broiler chickens’ blood

Abstract

The article presents data on the dynamics of morphological parameters of broiler chickens’ blood when spirulina biomass is introduced into the diet in the amount of 5 g/kg of compound feed. The use of spirulina biomass as part of the compound feed led to an increase in the number of erythrocytes, hematocrit, leukocytes, hemoglobin concentration in the birds’ blood of the experimental group during the experiment. The number and % content of agranulocytes, granulocytes, platelets, the average volume of erythrocytes and the average concentration of corpuscular hemoglobin in birds’ erythrocytes of the experimental group is characterized by uneven changes. Hematological studies revealed that in the birds’ blood of the experimental group by 42 days age, there was an increase in the number of neutrophils, basophils, platelets and an increase in the proportion of % of the content of neutrophils and basophils, and the number of lymphocytes, eosinophils and the proportion of their % content decreased.
