The degree of expressiveness of immune corrective effect of the applied biological products at calves of experimental groups was combined in direct ratio with increase of their general stability that was expressed by decrease in calves prevalence of diarrheas. Prevalence of diarrheas at calves has decreased in comparison with control animals on 80%. Absolute quantity of T-lymphocytes protected organism against majority of bacterial and viral infections has been increased due to application of complexes of biological preparates in blood calves. The most essential changes of this indicator aside increase were observed at animals of the 5th experimental group. The content of T-lymphocytes in this group has increased on 23,8% (P0,05) in comparison with calves at the same age from the control group. Being based on results of the lead research it is possible to establish that use of complexes of biologically active substances to calves of colostrum-dairy periods renders stimulating effect on the immune system, caused direct potentiative action of preparations on functioning of immune competent organs, preventing early immune deficiencies and gastroenteric diseases. The most expressed stimulating effect on immunological indicators of blood of calves renders joint application of cuticula of a muscular stomach of hens with vitamin B12, trivitamin, iodine-starch and zinc sulphate
