Nonspecific resistance newborn calves under the influence timogen

One experiment was carried out on newborn calves with parenteral injection of dipeptide thymogen, aimed to stimulate absorption of colostral immune globulins and formation of nonspecific resistance. Use of a preparation of Thymogen increased the level of white blood cells, protein and immunoglobulins of new born calves. After using the Thymogen we noted a significant increase leukocyte levels and gammaglobulins in blood of calves, which gives reason to believe that the thymus in newborn calves involved in the regulation of absorption of immunoglobulins and other important components of colostrum. Thymogen stimulated the formation of non specific resistance, which showed an increase in performance and bacterial activity of phagocytic blood of newborn calves. Increased nonspecific resistance calves accompanied by an increase in weight gain in dairy calves during rearing.
