Biosecurity indicators (existence of a written biosecurity plan, isolation, introduction of newly acquired animals into the herd, herd health, assessment of the personnel attitude towards equipment, traffic control, attitude towards visitors, feeding and watering control, manure management, disposal of dead animal carcasses, attitude towards other animals, rodents and birds control, sanitation) were viewed and evaluated by rating scale: (5) - excellent, (4) - very good, (3) - good, (2) - sufficient, (1) - insufficient, there are resources for improvement (0) - insufficient, with no resources for improvement. Obtained data were analyzed in the SWOT process, taking into account all the strengths, weaknesses, threats and opportunities for improving the biosecurity level. The situation in the center is rated as very good, with an average rating of 4.15. However, one disadvantage is serious and related to the boar facilities isolation possibilities, taking into account their location and the presence of two types of male breeding animals (boars and bulls) in the same location. Newly acquired breeding animals are purchased from various sources, but with a rigorous regime of control and not at the same time. Key words: analysis, biosecurity measures, boars, sperm production Introduction Artificial insemination (A.I.) is the routine technological procedure in contemporary swine breeding technology and important biosecurity measure as well. Fresh semen collected from healthy boars necessitates premeditated and correct treatment in order to prevent afterward contamination (Stanković et al., 2005).
210 B. Stanković et al. In epidemiologic terms, sperm is considered to be intermediary source of infection, becoming secondary source after being packed in single doses. Many viruses could be detected in boar semen, primarily during viremic phaze of infection, and some of them, like Foot and Mouth disease virus, PRRS virus, Vesicular Disease virus, Parvovirus, Picornaviruses, Adenoviruses, Japanese Encephalitis virus type B, Aujecsky virus and Reoviruses have great importance. Therefore, quality monitoring of boars before introducing them into herd and during being in reproduction center is essential (Stanković et al., 2007a). The amount of predicted biosecurity measures have to be defined by protected operation price, but preservation of certain biosecurity level is multifunctional. Primarily, it is essential part of farm programme of food safety. Furthermore, sophisticated and efficient biosecurity measures application leads to better herd health and their higher productivity, which means higher efficacy and profitability, and finally environment protection (Uhlenhoop, 2007). An assessment of all critical spots in technology chain of boar semen collecting, processing and storage, and the most important measures for semen preservation in order to achieve reproductive results were given in this paper. Materials and Methods During presented investigations, the effect of applied biosecurity measures in one reproductive center was evaluated, and failures and threats to biological quality of semen were analysed, as well as possibilities to improve present biosecurity level in operation facilities. There were 75 breeding boars of different breeds (Large White, German, Sweden and Dutch Landrace, Pietrain and Durock), as well as 82 Simmental breeding bulls. Investigation was performed using combining methods of interview and observation in respect of biosecurity indicators (existence of a written biosecurity plan, isolation, introduction of newly acquired animals into the herd, herd health, assessment of the personnel attitude towards equipment, traffic control, attitude towards visitors, feeding and watering control, manure management, disposal of dead animal carcasses, attitude towards other animals, rodents and birds control, sanitation), which were evaluated according to numerous parameters and other elements. In order to evaluate them, grades were defined: (5) - excellent, (4) - very good, (3) - good, (2) - sufficient, (1) - insufficient, there are resources for improvement (0) - insufficient, with no resources for improvement, and rating scale: 0-1,99 insufficient, 2,00-2,49 sufficient, 2,5-3,49 good, 3,5 – 4,49 very good and 4,5 – 5,00 excellent, were defined. Obtained data were analyzed in the SWOT process, taking into account all the strengths, weaknesses, threats and opportunities for improving the biosecurity level.
