In the conditions of the Republic of Belarus there were presented the results of a veterinary and sanitary assessment and bacteriological investigation of sheep slaughter products, which showed meat serviceability for consumption after application of Triclafen suspension. Application Triclafen suspension did not render negative influence on an organism of animals. It was proved by organoleptic and laboratory research of meat of slaughter animals of experimental and control groups. The meat obtained from healthy sheep which were administrated the suspension in accordance with microbiological indicators proved to be of good quality and corresponded to the established norms (Sanitary regulations and standards 11 - 63 Republic of Belarus 98): it had the general bacterial content within admissible limits and did not contain agents of anthropozoonosts, alimentary toxicosis and toxinfections and it can be sold without any restrictions.

In the conditions of the Republic of Belarus there was realized a complex of studies of quality swine slaughter products against the background of combine applications of the albuminous-vitamin-mineral additive Immovit and an extract of hill-growing saltwort for the preventive maintenance and treatment of a toxic dystrophy of liver. Research results showed the analysed preparations did not render negative influence on quality and safety of produced meat products. Against the background of application of the albuminous-vitamin-mineral additive Immovit in combination with an extract of hill-growing saltwort there was stated the improvement of swine slaughter product quality. In products from the animals which were administrated with a complex of examined preparations there was stated an optimized moisture content, the increasing of a relative biological value of a product (101,3-103,8%), and according to the indexes of bacterial safety the experimental pork considerably surpassed the meat indexes from animals of control groups. At the same time, in slaughter animal products of control groups there were revealed coliform bacillus bacteria.

In the conditions of the Republic of Belarus there was analyzed the productivity of 13-18-month old young stock of cattle which was bred for meat with various levels of energy value nutrition. Also, there were noted their slaughter qualities and chemical composition of meat. Administration of diet rations with an increased level of exchange energy and the best indices of protein fissility rendered a positive influence on productivity of young stock of fattening cattle and made it possible to obtain 1103-1100 gram of body weight gain. As a result, the energy value gain was 22,9-22,6 MJ along with conversion of metabolizable energy at a gain - 24,7-25,3%. Consumption of metabolizable energy per 1 MJ along with body weight gain were within 4,7-5,0 MJ. Feeding of rations with various levels of the studied factor rendered the positive influence on slaughter qualities, made it possible obtain slaughter yield of 53,6-54,6% at an optimum ratio of nutrients in meat. Feeding of bull calves with diets with excessive content (up to 10%) of metabolizable energy made it possible to lower the prime cost of obtained breeding products on 0,55%.

In the conditions of the Republic of Belarus there was analyzed the efficiency of application multi-enzyme preparations (drugs) Ehkozim (contained beta-glucanases; endo-xilanase; cellulose) and Vitazim (contained complex of enzymatic carbohydrases: xylanase; cellulose; beta-glucanases) in diets of lying hens. Vitazim was applied for destruction of complex structures: dietary fibre, protein, starch. Ehkozim was applied for albuminolysis of the main nonstarch polysaccharides of fodders. It was established that application of preparations in feeding of lying hens promoted the increasing of biological value of poultry meat, and prove to be economically expedient. Poultry meat of analyzed samples in accordance with physical, chemical and bacteriological indices, as well as in accordance with biological value and harmlessness was not worse than meat of control samples. As a result of the realized bacteriological research of all experimental samples of meat and internal organs there were not stated microorganisms Е. coli, S. aureus, bacteria of sort Proteus, B. сеreus and sulfate-reducing clostridium, salmonellas.

In the conditions of the Republic of Belarus there was studied the possibility of increasing of meat yield productivity of ducklings of Temp cross in the conditions application of parental lines of Peking ducks of German breeding Stolle Seddin Vital (SVV) cross. In course of the study there was realized a comparative evaluation of linear and crossbred ducklings in accordance with meat qualities and blood indexes. There were presented the results of morphological composition of liner and crossbred duck carcasses; dynamics of changes of lipid exchange (total lipids; cholesterine; triglyceride) of ducklings; morphological composition of carcasses of father and mother combinations; blood indexes of ducklings; blood indexes of crossbred ducklings of final combinations. Research results showed that crossbred ducklings had high meat properties which exceeded the purebred ones. In ducklings with lower indexes of fattiness of carcasses there was noted the lowering of concentration of total lipids, cholesterine and triglyceride in blood.

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.

Analysis of veterinary and sanitary examination and quality of cattle slaughter products after cattle clamidiosis was realized in the conditions of the Republic of Belarus from April, 2004 till January, 2006. Over all these research periods there were studied 1579 cattle heads and their slaughter products. The usual salting of meat and other products with the purpose of their clearing from chlamydiosis was unsuitable for practical application. Due to long-term (1,5-9 months) persistence of chlamydia in parenchymal organs for the prevention of people infection and chlamydiosis spreading it is necessary to realize slaughter of diseased animals at a diseased animal slaughter house or in a killing department at the end of working shift with observance of measures of individual preventive maintenance and the subsequent disinfection of a premise, the equipment, stock and tools.

In the conditions of the Republic of Belarus there were analyzed high productive traits of meaty calves and cross breeds bred in accordance with a system cow-calf, as well as the possibilities of using veal meat obtained in ecologically safe areas for infant food production. At the age of 6,5-7 months the weight of fresh carcass of bull-calves of sharolez breed in comparison with aberdin-angus х black-motley herdmates was on 41,6 kg (Р less than 0,001) higher, carcass yield and slaughter yield – on 13,8% (Р less than 0,001) and 13,6% (Р less than 0,001), respectively. The fat content in sharolez meat was 4,9% against 8,9%; protein - 21,9% against 18,8%. The black-motley suckling bull-calves surpassed their herdmates which were grown up by technology of dairy cattle breeding at the age of 6-6,5 months according to indexes of weight of fresh carcass - on 16,3 kg or 21,7% (Р less than 0,01); according to indexes in a slaughter yield - on 16,6% (Р less than 0,001); and according to indexes meat flesh in a carcass - on 1,5%. According to quality indexes, amino acid structure, acceptable concentration of toxic elements content, pesticides, antibiotics, radionuclides and other harmful substances the veal meat of calves which were bred on a system a cow-calve in ecologically pure zones proved to be important meat raw materials to produce infant food products.

In the conditions of the Republic of Belarus there was studied the veterinary and sanitary quality and safety of poultry slaughter products after application of a natural biological corrector VitoLAD produced in Belarus on the basis of cultivation of nonpathogenic strain of fungi Fusarium sambuninum MKF-2001-3 used for restoration of dysfunction disorders. As a result of the realized bacteriological research there were marked no pathogenic and opportunistic organisms in all experimental samples of meat and internal organs. Indices of biological value of meat of three experimental and control group had no authentic differences. Displays of toxicity for infusorians were not marked. Poultry meat of investigated samples in control, and all three experimental groups (doses of 0,25 ml/head - the second experimental group, a dose of 0,5 ml/head - the third experimental group and a dose of 1 ml/head - the fourth experimental group) in diets of which there was added the natural biological corrector VitoLAD, proved to be good-quality and harmless. In accordance with organoleptic, physical and chemical, bacteriological indexes, as well as biological value and harmlessness did not concede to meat of the control group. The complex veterinary and sanitary estimation of bird carcasses of three experimental and control groups did not show any deviations from existing standards that made it possible to organize production realization without restriction.

In the conditions of the Republic of Belarus there was realized a comparative study of meat productivity of mongrel Gereford х black-and-white heifers ad purebred black-and-white heifers in the conditions of different levels of concentrated feedstuff in cattle diets; and determine the most efficient and long-term method of animal breeding for meat. Research results showed that breeding of meaty of hybrids of Gereford х black-and-white heifers of the second generation without using the feeding concentrates in their diets or on using rations with a low rate of feeding concentrates (10-20%) proved to be more effective, than breeding of purebred black-and-white herdmates (for which specific density of the concentrated forages in diets made up 20% through pregnancy). Hybrids on Gereford breed in accordance with meat productivity level surpassed the purebred black-and-white animals. The most considerable results were marked at hybrid heifers with relative density of concentrates in a ration of 20% which in accordance with slaughter weight indexes surpassed the herdmates of black-and-white breed on 39,1 kg or on 23,68%, in accordance with slaughter yield - on 8,2%, in accordance with fresh carcass weight - on 37,9 kg or on 23,8%, in accordance with weight of inner porc - on 1,19 kg or on 20,62%.
