INFLUENCE OF THE DRUG TREKREZAN ON BIOCHEMICAL BLOOD COUNTS OF LAYING HENS
This article represents the results of the research of the drug trekrezan on biochemical blood count. It is determined, that in experimental group of laying hens’ protein metabolism is activated. Specifically - mathematically reliable increased level of total protein, albumin, globulin and total cholesterol. At the same time, level of urea decreases. Mentioned changes characterize an increase in egg productivity and stimulation of the immune system. Toxic influence of this drug on birds’ organism wasn’t detected.
