ABSTRACT
The aim of the present study was the comparison of carcass and meat quality traits of commercial pigs of various crossbreeds from two major Slovenian herds. The analysis is based on phenotypic data from field trials which have been collected in the last past five years within the Slovenian breeding programme. Important differences in carcass traits were observed between two herds and were associated to different crossbreeds used. In spite of that economically important result on the slaughter line (lean meat %) was similar for both herds. Meat quality traits were also significantly different between the two herds. Again, the difference could be ascribed to crossbreeds used. However, since the herd effect is connected with abattoir effect, different ante-mortem conditions and/or lower robustness of these animals to premortal stress could also be contributed to the observed differences. The presented results give important information on the state-of-the-art regarding meat quality of Slovenian pigs.

ABSTRACT
Though in Hungary the cropping of genetically modified (GM) plants is not allowed the processed products containing them are already present in the country. The scheme is shown in the article through a case study. As much as 20 dairy farm managers from the region were asked and the data obtained show that in cattle feeding GM soy is widely used because this is the only forage that can be purchased at a reasonable price. As an alternative the promotion and propagation of using non-GM protein crop can be enlisted representing a comparative advantage on European markets.

ABSTRACT
In this research the fatty acid profile in Busha’s, Cika’s and Simmental’s milk was investigated. For research purpose 42 milk samples were collected during July (Busha, n = 15; Cika, n = 17 and Simmental, n = 10). All cows were held in outdoor system. Busha’s milk had significantly (P < 0.05) lower content of SFA, as well as significantly (P < 0.05) higher content of MUFA and PUFA in regard to Cika’s and Simmental’s milk. Lower SFA/MUFA, SFA/PUFA and n-6/n-3 PUFA ratios, but higher content of n-6 PUFA in Busha’s milk in regard to Cika’s and Simmental’s milk was also determined. Statistically significant differences were not found (P > 0.05) in cows milk in regard to n-3 PUFA content. However, in Busha’s milk higher content of DHA (P < 0.05) in comparison to Cika’s and Simmental’s milk was found. Cika’s milk had statistically significantly higher content (P < 0.05) of CLA than Busha’s milk. Significant differences in fatty acid profile between Busha’s milk and milk of Cika and Simmental breed were determined, but for assessment of effects of system of keeping and keeping altitude, lactation stage and parity, as well as of other possible effects on milk fatty acid profile, further investigation is needed.
