Influence on the development of bioginseng bursa of fabricius laying hens

The article deals with the study of the effect of meal bioginseng (adaptogen herbal) on morphological and functional development of the bursa of Fabricius of laying hens. There is currently a large number of immune modulators are quite expensive, which does not allow their widespread use in veterinary practice, in connection with the search for low-cost, technologically advanced in the use of means and methods of treatment and prevention of poultry diseases is urgent.
