In the conditions of the Republic of Belarus there was determined the therapeutic efficacy of combined application of a complex antibacterial veterinary drug (containing lincomycin and spectinomycin) and Trivitim for the treatment of calves with respiratory diseases. In course of the study of 12 1-1,5 month old calves with respiratory diseases there were analyzed the hematological blood indexes, white blood cell differential and content of total protein in blood serum before the beginning of treatment and on the seventh and fourteenth days after beginning treatment. Research results showed that application the antibacterial veterinary drug in complex therapy with Trivitim in treatment of calves proved to be efficient. Their administration shortened the terms of recovery and prevented animal death as well as promoted the normalization of hematological and biochemical blood indexes.

In the conditions of the Republic of Belarus clinic and production conditions there was analyzed the prophylactic and therapeutic efficacy of a new national complex iron dextrane preparation Ferovital against deficiency (nutritional) anemia of new-born cattle and swine. In course of the study there were analyzed results of hematological and biochemical tests of blood of piglets which were administrated with Ferovital preparation. There were also marked the general economic index: live weight gain, disease incidence, piglet death rate, etc. Research results showed that the Ferovital preparation had an expressed prophylactic and therapeutic efficacy both in clinic and production conditions.

In the conditions of the Republic of Belarus there was determined the influence of lactulose of the clinical state of weanling piglets, as well as analysis of its preventive and therapeutic efficacy. For the experimental group of piglets in course of 5 days before weaning the lactulose for administrated daily in combination with feed in course of 5 days in dose of 0,002 gram per kilogram of live weight. In 3-5 days after weaning the diarrhea was stated in 4,1% of experimental piglets. The clinically evident efficiency of application of the synthetic disaccharide was showed in lowering of disbacteriosis level in weaning piglets on 33,7%. Besides, there was analyzed the therapeutic efficacy of lactulose for weaning piglets diseased with gastroenteritis. They were administrated lactulose in dose of 0,03 grams per kilogram of live weight once a day after feeding in course of 7 days. Haematologic and biochemical blood indexes of experimental and control groups of piglets were analyzed. Research results showed that application of lactulose promoted the creation of optimal conditions for beneficial microflora, stimulated its reproduction, suppressed the development of opportunistic pathogens.
