Since 1975, he started add-on post-graduate study and in 1978 he defended dissertation thesis („Serum concentrations of vitamin E in cattle and sheep in relation to age, season, pregnancy, breed, and application of its preparations'). In the framework of contemporary regulations in 1982 he was named associated professor and after 8 years of active pedagogic and science-research activities he defended his doctor dissertation thesis („Clinical picture and biochemical indices after application of VX substance in cattle, sheep, and swine'). After habilitation and inauguration hearings („Periods of low vitamin E concentrations in the blood serum of pigs, diagnosis and prevention) he was designated professor for internal diseases of animals and pharmacology by decree of the Slovak President in 1997. In 1989 – 1991, he was the head of the university department and vice-rector for scientific-research activities and foreign relations.

He is the chairman of Committee for Defence of Doctor Dissertation Thesis (DrSc.) at science branch 'Internal Diseases of Animals', member of special committees at science branches: 'Veterinary Morphology', 'Nutrition and Dietetics', 'Parasitology', 'Other Related Branches of Veterinary Sciences'.Prof. Kováč is engaged in advisory and expertise activities aimed at helping agricultural practice, he closely cooperates with various enterprises in proposing and verifying of new remedies and aids for agricultural and veterinary practice. His present activities classified Prof. Kováč among head representatives of Slovak veterinary medicine, particularly in the field of internal diseases. This is proofed primarily by working out of aetiopathogenesis, diagnosis, therapy and prevention of the most important metabolic disorders in livestock and wild animals. Scientific and research activities of Prof. Kováč are presented at home, as well as abroad. Till now, he is a co-author of 22 Slovak scientific monographies, 11 foreign scientific monographies, author and co-author of three academic textbooks, 7 scripts, 91 scientific works in the Current Contents journals (88 foreign and three Slovak), 239 scientific and special papers in other journals (62 foreign and 177 Slovak), 141 scientific contributions in reviewed proceedings of foreign conferences, 371 scientific works in reviewed proceedings of Slovak conferences. Prof. Kováč, as the principal investigator and co-investigator, participated in 23 defended final reports of state research tasks, 6 department research tasks, 2 international grant projects, and 6 grant projects within SR; 11 continuous research reports, 9 research and special works based on economic activities. He worked out 23 reviews of issued works, 42 opponent reviews of qualifying works, 3 special translations, 36 scientific-popular and informative contributions, he took part in the elaboration of subject words in four dictionaries and encyclopaedias, and other 96 published works (to prominent jubilee colleagues, information on important scientific and special events at home and abroad). At the present, he is the principal investigator of VEGA and APVV grant projects, and co-investigator of several other projects. Among the published works of Prof. Kováč, the most important is knowledge of periods of low vitamin E concentrations in the blood serum of cattle, sheep and swine in relation to stage of pregnancy, age, season, and response to various ways of administration of remedies based on vitamin E and selenium; clarifying of aetiopathogenesis, diagnosis, therapy, and prevention of nutritional muscular dystrophy in young cattle; hypovitaminoses of B-complex; interactions of natural antioxidants and poly-unsaturated fatty acids; the use of natural sorbents; knowledge of clinical picture and metabolic indices in livestock and wild animals in areas exposed to industrial and chemical contaminations. In close relation to educational stays abroad, Prof. Kováč paid also considerable attention to the clarification of aetiopathogenesis, diagnosis, therapy, and prevention of several organ entities, and methodical procedures. In the recent period, Prof. Kováč orientates his collective, particularly research activities of his PhD students, to use components of genomics, proteomics, nutrigenomics, metabolomics, for real selection of animals by health signs, which lags behind the selection of food animals based on production traits only. Prof. Kováč participated meaningly in under-graduate education within students' research and special works (21 students), diploma thesis (12 the students), young scientific-pedagogic workers for needs of UVM (5 PhD.), practice (2 PhD.), and foreign countries (2 PhD.); three associated professors, two regular professors; building up of former Department of Internal Diseases of Ruminants and Swine, later 2nd Clinical Department, and presently the Clinical Department for Ruminants at UVM Košice, as an up-to-date academic place of work within the University of veterinary medicine in Košice, as well as in European space (through acquirement of financial resources within developing projects).
