Data of crossbreeding for beef production was analyzed for Slovenia. Analysis was made on data for young bulls (aged 12-24 months) which were slaughtered in Slovenian abattoirs in the year 2014. A comparison was made for crossings of main cow breeds (Holstein, Brown, Simmental) with main meat breeds (Limousin, Charolais, Belgian blue) used in Slovenia. The improvement of carcass value when crossing with meat breeds was proportional to the dairy type of the cow, it was the most important in the case of Holstein, a little lesser in the case of Brown, whereas much smaller effect was observed in the case of Simmental breed. Crossing with Charolais was the most important for growth performance (higher carcass weight and net daily gain), whereas crossing with Belgian blue was the most efficient for improving conformation and decreasing fatness. Practically no improvement (in terms of EUROP classification) was observed in the case of Simmental × Limousin crossing.
F.17 Transfer of existing technologies, know-how, methods and procedures into practice
COBISS.SI-ID: 4718952The present paper presents the first results of meat quality assessment in longissimus dorsi muscle of Simmental bulls (LS) reared at the test station ŽIPO Lenart. The results comprise meat technological quality measurements of pH, colour, meat tenderness (shear force), water-holding capacity, intramuscular fat in relation to the effect of two-week storage in vacuum package, carcase characteristics and the origin of bulls. Special emphasis was given to the changes in tenderness and colour stability. Additionally, meat spectral data were collected using near infrared spectroscopy (NIRS) and were further used for completing the calibration equations to determine various parameters of meat quality (chemical composition, studying the possibility of predicting tenderness and oxidation).
F.23 Development of new system-wide, normative and programme solutions, and methods
COBISS.SI-ID: 4719464In 2015, a technical publication entitled Overview of slaughter and carcass quality of cattle in Slovenia in 2014 was published. The aim is to gather and present available data on the slaughter and carcass quality of cattle reared and slaughtered in Slovenia. The review shows a range of slaughter, carcass quality and growth as an indicator of the intensity of fattening. Data are shown at the level of category, breed and slaughter slaughterhouse and some of them are additionslly compared to the previous years. The analysed dataset comprised 105.045 estimated and slaughtered cattle. Compared to 2013, 2.7% less cattle was slaughtered and estimated.
