Investigation of the proteolytic activity of liver trematodes in goats of Khizi-Khachmaz zone of Azerbaijan

The article presents experimental data on the detection of proteolytic activity of liver trematodes in the goats of Khizi-Khachmaz zone of Azerbaijan in different seasons of the year. Determination of the enzymatic activity was carried out spectrophotometrically using a Folin reagent on a Specol 1500 spectrophotometer (Analitik Jena). The maximum peak of intensity of proteolytic activity of trematodes isolated from goat liver was detected. The maximum value of the enzyme activity was reached in March equal to 170 μg of tyrosine per gram of wet weight of the helminth, and the minimum in June reaching 70 μg of tyrosine per gram of wet weight of the helminth.
