The spectrum of acaricides changes continuously and improves. At the same time, big attention is given to research of new, more effective preparations meeting modern requirements. Research on studying the efficiency of Akaribil preparation against swine sarcoptosis (Sarcoptidae) was realized in the conditions of swine breeding farm in the Republic of Belarus. The preparation possesses high insect-acaricidal activity. In the conditions of the preparation storage and repeated opening of a ware in the course of tests there were stated no changes in drug smell or color. The scheme of the preparation application is applied in industrial production technology. It possesses anti-inflammatory properties, antiseptic stimulating healing of skin damages, does not irritate integuments, renders weak irritating effect on mucous membranes of eyes. In recommended doses Akaribil does not cause any adverse effects and complicating disease. There were stated no contraindications to preparation application. High therapeutic efficiency against arachnoentomosis was proved. Application the preparation made it possible not only to reduce disease incidence and animal death, but also to facilitate the severity of scabietic diseases. As a result of realized research it was established that efficiency of Akaribil against swine sarcoptosis was 100%.

In the conditions of the Republic of Belarus there were studied the anthelminthic properties of preparative forms of elecampane (Inula helenium) (herbal infusion, tincture, liquid and dry extracts). Research results showed that the analyzed preparative forms in the administrated doses possesed high therapeutic efficiency against strongyloidosis and strongylatosis of gastroenteric path of sheep. Thus, according to results of research it was established, that the highest therapeutic effect rendered herbal infusion of elecampane in a dose of 6 ml/kg live weight once a day three days continuously; and the antiparasitic efficiency was 60%. Application of elecampane tincture in a dose of 1 ml/kg live weight once and 0,5 ml/kg of live weight twice rendered the 100% therapeutic effect. Administration of a liquid extract of elecampane in a dose of 0,2 ml/kg live of weight once and 0,1 ml/kg of live weight twice rendered 100% therapeutic effect. Application of elecampane dry extract in a dose of 30 mg/kg of live weight once and 25 mg/kg of live weight twice rendered 100% therapeutic effect.

In the conditions of the Republic of Belarus there were studied circadian rhythms of some haemotological and biochemical blood indexes of clinically healthy calves and calves with a respiratory syndrome. There was analyzed the efficiency of administration a new complex mineral preparation CMP for correction of internal desynchronoses in complex therapy of calves with respiratory pathologies. Diseases of calves with a respiratory syndrome were accompanied by infringements of circadian fluctuations rhythm (internal desynchronosis) of haemotological and biochemical blood indexes. Application of an antimicrobial preparation Ampicillin for treatment of respiratory diseases of calves promoted the recovery of calves. Introduction of CМP preparation into therapeutic regimen of calves with respiratory syndrome proved to be rather effective; it promoted the correction of metabolic desynchronoses which accompanied the basic disease. Combined application of CМP and Ampicillin made it possible to speed up the clinical recovery of calves and on 30% to prevent animal mortality.

In the conditions of the Republic of Belarus by an example model of a purulent wound at rats there was realized an experimental study of pharmacological activity of a medical remedy PhytoMP (containing active substances of Macleaya microcarpa (Maxim.) Fedde of Papaveraceae family; and Plantago major L. of Plantaginaceae family) in the form of powder. It was established, that the intensity wound-healthing effect depended on a ratio of the components plume poppy / greater plantain 1 + 1:1, 2:1, 1:2. Studying of the remedy safety showed that PhytoMP in the maximal dozes was not toxic for animals after a single unitary intragastric administration in dose of 50000 mg/kg to mice and in dose of 20833 mg/kg to rats. The mentioned above indexes surpassed the recommended for human dose after application tonsilles (1,428 mg/kg) in 35014 and 14589 times, and also the recommended for human doses for application at a wound with size of 2x2 square cm (11,424 mg/kg) - in 4377 and 1824 times, respectively.

Belarus concerns a biogeochemical province with the lowered content in environment of such microelements, as iodine, selenium, copper, cobalt, manganese, zinc and some other. It conducts to infringement of intensity and an orientation of processes of an exchange of proteins, carbohydrates, lipids, and finally - to decrease in their growth and development of an organism of young growth. High cost of foreign preparations for treatment and preventive maintenance of an alimentary anaemia, low bioavailability of iron and toxicity do not provide purposeful disesase control and immunodeficiencies arising on its background. The special urgency is got by research of means of complex preventive maintenance of an alimentary anaemia and immunodeficiencies. It has been established that the recipes N1-3 have proved to be non-toxic for laboratory animals and have no effect on the meat quality.

In the conditions of the Republic of Belarus there was realized an experimental study of a new method treatment of calves diseased with abomasoenteritis by means of application of a preparation Ranitidin. As a result of realized research it was established that the preparation had an expressed therapeutic activity. Inclusion of Ranitidin preparation into the complex therapeutic regimen of calves sick with abomasoenteritis with the enteral feeding once in day in a dose of 0,15 g promoted the reduction of duration and decrease in severity of the disease. There were presented the results of biochemical blood indicators in trial and control groups of calves, haematologic indices in trial and control groups of calves prior to the beginning of experiment and in the end of the test.
