The nonspecific reactivity of the hens under the influence group size with the same stoking density in cages-analogues by design was studied. It was found that with a decrease in the hens group size there is a shift of leukocyte formula to the left, the predominance of nonspecific protective cells, which occurs due to functional increase in bone marrow proliferative activity and is expressed in increased heterophiles and increased activity in the microphage-macrophage immune response system.
