Variability of phosphatases in the male reproductive system of some domestic bird species

Abstract

The activity of acid and alkaline phosphatases from reproductive tracts of domestic birds was studied. In the reproductive season the highest activity of both studied enzymes was found for drake’s testes, followed by gander and male Japanese quail. The distribution of acid and alkaline phosphatases in other parts of the drake’s reproductive system was studied. It was proved that the activity of the studied enzymes was significantly higher in testes than in epididymes and ductus deferens. In the resting phase, a slight decrease of acid phosphatase activity in all tissues studied was observed, whereas a remarkable increase of alkaline phosphatase activity in all tissues was noted. A higher individual variability in testes mass and enzyme activities in the resting phase was noted.
