Abstract:
Spirulina platensis is widely used as a biotransformer of bioelements and as a producer of biologically active substances with a wide spectrum of use. The current study is aimed at objectively debating the effects of ZooBioR (obtained from Spirulina platensis) on health, and especially on the marker parameters of the clinical and hematological status, protein, carbohydrate, mineral metabolism, liver function and productive potential in hens, in the first technological period of laying. The experiment was performed on 5 groups of birds (of 14 heads/group), in 4 of which the food was supplemented with the remedy ZooBioR in different doses (5.0; 10.0; 15.0; 20.0 mg active substance/kg fodder). The tested bioactive product is well tolerated by birds, improves the hens`health, in the first laying period, and essentially contributes to improving the metabolic processes in the body, a hypothesis confirmed by the high values of egg production.
