The effects of zoobior feed supplementation of laying quails on the content of pseudocholinesterase and ceruloplasmin in blood serum

Our study focuses on the action of the ZooBioR product from Spirulina platensis on laying quails. The quails (n = 200) operated under poultry farm conditions were divided into four groups of 50 quails each, from the age of 55 days. Birds feed in three experimental groups (EG) was supplemented with the tested product in different doses (10.0, 15.0 and 20.0 mg active substance/kg feed), and administered to the birds, during the study period - 123 days. Birds in the control group were on a regular diet. Quails from all groups benefited from the same technology conditions in force. Blood was collected 3 times consecutively: at the beginning of the study (n = 5), after approximately 1 month, and at the end of the experiment, from 5 birds from each group (total, n = 45 samples). It has been established that the tested product stopped the decline of pseudocholinesterase in quails from all experimental groups by 15.7-37.2%, compared to the control, a tendency also reported at the end of the study. In conclusion, ZooBioR administered with feed to quails, positively influences the proteosynthetic function of the liver in particular and the metabolic adaptation processes in general.
