Hematological indicators of the marsh frog during stimulated spawning

When breeding frogs on a farm, it is necessary to monitor their health status, and the most convenient method of control is a blood test. Hematological parameters of marsh frogs were studied before and after spawning. After hibernation at a temperature of 4°C from the first week in the pool, the frogs were subjected to hormonal stimulation with a mixture of drugs “Gonadotropin chorionic” and “Surfagon”, the next day successful spawning with 100% fertilization of eggs was observed. A reduced number of red blood cells was found in the blood of frogs after spawning. The proportion of neutrophils and eosinophils in the leukogram of frogs after spawning decreased, the number of monocytes increased 3 times, the proportion of basophils increased. The stimulated spawning of the marsh frog was reproduced for the first time in captivity under the control of an analysis of hematological parameters, which showed the possibility of using this process in raniculture conditions.
