The purpose of this study is to assess the suitability of the statistical techniques employed in papers published in the Korean Journal of Veterinary Research from March 1997 to March 1999 and it is hoped that the critical assessment may be of help to other researchers preparing their works for publication. Of the 246 original papers 94 were inclluded in the analysis. of 62 papers with the measure of central location and dispersion of data 34(54.8%) used them correctly:9 (39.1%) of 23 for t-test; 1 (33.3%) of 3 for correlation analysis; 7 (43.8%) of 16 for analysis of variance (ANOVA); 5 (62.5%) of 8 for chi-square test; 44 (71%) of 62 for description of p-value. A number of papers employed ANOVA did not perform subsequent analysis of multiple comparison. Compared to the results of others, relatively higher proportion of papers in the present study was evaluated as appropriate analysis. The reason is that papers described insufficiently on the study design were not included, and evaluation items were restricted to the cases violated seriously ingerent assumptions for each statistical technique. Statistical misuse or abuse appeared in the study is due to lack of knowledge on statistics and short of its importance for improvement the quality of paper. Because an inappropriate analysis can lead the readers to misunderatand on findings, observed statistical analyses must be valid,and correctly undertaken. It is suggested that more intensive statistical refereeing are needed,and the communication should be allowed for the controversial points.

The article features the data on scientific research of the spread and etiology of bovine dermatophytoses. Work was carried out in 2007-2009 in farm holdings of Minsk and Vitebsk regions of the Republic of Belarus. Principal causes of diseases occurrence are the mechanical traumas caused first of all by infringement of animals maintenance of hygienic norms, also infringement of animals feeding technology. The automicroflora on intact skin has been studied. Realized study helped to determine methods and means of dermatophytoses treatment.

Determination of a degree and stages of metabolic disorders of aborted sows and sows which gave birth to dead fetus was realized in the conditions of the Republic of Belarus. Analysis of biochemical profile of blood of experimental sows was given. Typical deviations of biochemical status indexes in the conditions of reproduction pathology were determined. The highest degree of deviations of biochemical blood profile (indexes of fat, protein and mineral metabolism) was stated at aborted sows. At sows which gave birth to dead fetus there were stated abnormalties functional state of kidneys and liver, indexes of carbohydrate and mineral metabolism.

Studies of morphological and morphometrical particularities of rennet of newborn calves with different degree of antenatal hypotrophy were realized in the conditions of the Republic of Belarus. Scientific-and-production researches were spent in 2007 - 2008 on the basis of agricultural production co-operative Dembrovo (Shchuchinskij district, Grodno area, Belarus), agricultural production co-operative Okhovo (Pinsk district, Brest region, Belarus) and research laboratory of Grodno State Agrarian University (Belarus). For an estimation of morphofunctional maturities there were used 165 1-day old calves. Research results showed that in the studied calves the basic indexes of glanderous apparatus of rennet proved the different degree of morphofunctional immaturity. In calves with hypertrophy in the first days after birth there stated an active morphogenesis of all cytological components of rennet

Study of sensitivity of Paenibacillus alvei to different antibiotic preparations (penicillin, tetracycline, neomycine, kanamycin, ampicillin, polymyxin, laevomycetin, enrofloxacin, tylosin, and streptomycin) was realized in the conditions of the Republic of Belarus. As the material of the research there was used the culture of agent the European foul brood caused by Paenibacillus alvei. Determination of therapeutic effectiveness of antibacterial agents in vitro conditions made it possible to choose the appropriate preparation for its use at beeyards with European foul brood caused by Paenibacillus alvei. During the experimental work there were used 10 antibacterial disks with various antibiotics. The best result against Paenibacillus alvei was shown by Tilozin, the diameter zone of growth inhibition was about 47,2+/-3,43 mm.

Sensitivity of European Faulbrut causative agent to Gentavet preparation was studied in the conditions liquid nutritive media in vitro in the Republic of Belarus. Research results showed that the studied preparation rendered the poisonous influence on European Faulbrut causative agent in concentration of 0,3 mkg/ml with the maximum rate 1:131072. The antibiotic showed the bacteriostatic ability in concentration of 0,15 mkg/ml. The antibacterial preparation did not influence the European Faulbrut causative agent in concentration of 0,01 mkg/ml. The total bacteriostatic effect the drug showed in concentration of 0,22 mkg/ml and its dilution of 1:196608.

The realized studies of an experimental series of inactivated vaccine showed that the developed biological preparation made it possible to achieve high preventive efficiency in the conditions of cows heavy with calves for the creation in newborn calves the expressing immunity after milk feeding in the first hours of their life. As a result realized in the conditions of the Republic of Belarus production experiment of emulsified vaccine against rotavirus infection and colibacillosis of cattle in animal breeding farms of different regions of the Republic the prophylactic efficacy of a developed vaccine made up 97,9-98,9%. Research results showed that the developed inactivated vaccine caused at the immunizated animals the formation of specific antibodies at a higher level in comparison with other analyzed national and foreign analogue preparations.

Research on working out of a new fodder additive on the basis of rape (Brassica napus) phospholipids which included mineral substances necessary for normal functioning of cattle was realized in the conditions of the Republic of Belarus. Results of biochemical analysis of 35240 blood samples revealed that 15-40% of studied animals had abnormalties in vitamin, protein and mineral metabolism and lowering of immunobiological disease resistance. There was correlation dependence between the degree of metabolic orders and the state of forage reserve of a forage reserve. The lowering of forage reserve caused the increasing of metabolic disorders. As a whole forages of the surveyed farms were low in content of copper, zinc, cobalt and selenium and could not provide physiological requirements of animals without introduction into rations of specialized additives

Data on changes of infectious titer of Porcine Reproductive & Respiratory Syndrome (PRRS) virus depending on variability of cultivation conditions was analyzed in the conditions of the Republic of Belarus. There were determined the regimes of cultivation which made it possible to minimize the terms of virus containing material production up to 3 days. The following factors influenced the infectious titer of PRRS: adaptation to cell culture; completeness of cell culture monolayer; number cells moving into stage of logarithmic growth; infectious dose of virus; storage duration; usage intensity.

Investigation of histological structures of liver of fattening broiler chickens after application of concentrate of E and F vitamins produced on the basis of rapeseed oil was realized in the conditions of the Republic of Belarus in order to evaluate their efficiency for prophylaxis of massive hepatic necrosis. Research results showed that application of the vitamins on the basis of rapeseed oil promoted the support of structural properties of hepatic cells that proved their higher antioxidant efficiency in comparison with synthetic vitamin analogues
