Opis: The most sustainable dietary patterns involve the consumption of plant-based (vegan) foods, excluding or reducing animal products, including meat, fish, and dairy, yet there is a lack of research on determinants of sustainable dietary patterns in central European countries. The present article aimed to examine the prevalence of sustainable dietary practices and attitudes among the Slovenian public and to investigate the role of education in fostering sustainable dietary patterns. We analyzed a representative national sample of Slovenians, with data gathered in 2019 (ISSP/Slovenian Public Opinion; N = 1079; 51.2% females). The results indicate that most Slovenians do not have sustainable dietary practices or attitudes with regard to health, the environment, animals, and dietary minorities. One in four Slovenians consume meat at least once per day and one in two consume meat three to six times per week. In addition, 78.2% of Slovenians consume milk at least three times per week; more than half consume milk daily or more often. Fish consumption is the least frequent among the three food groups. At least two-thirds of Slovenians also hold attitudes that are low in sustainability. Results also show that, after controlling for confounding variables, higher educational level emerged as an independent predictor of lower meat consumption, but not of lower fish or milk consumption. Furthermore, those in the lowest educational group are significantly less likely to hold sustainable attitudes than those in the higher educational group. Finally, current student status only decreases meat consumption. Since our results show an educational gradient in meat consumption and attitudes, public health and environmental campaigns should focus on the less-educated groups, encouraging them to reduce meat intake and fostering more sustainable attitudes.

Opis: Using of public procurement as a tool for promoting innovations has captured interest of many researchers in recent years. However, most of the research is focused on the impact of public procurement on the company's innovativeness. The article discusses the findings of the literature on this topic and proposes a model on how to transfer the concept from the company level to the level of the whole country. One of the biggest problems is unavailability of appropriate measures of this phenomenon, so the authors suggest that the concept of Public procurement for innovation can be approximated by participation of criterion of the most economically advantageous tender (MEAT). Implementation of this criterion in choosing the best offer can be supported and facilitated by using of ICT which can improve the efficiency of procurement process and enable more innovations.

Opis: In testing conditions six groups of broiler chickens were tested for the effect of feed addition Bergafat and standardised fats added in the feed in the quantity of 3,9% in starter, 8,5% in grower, 8,6% in finisher, and 9,3% in endfinisher. Among testing groups no differences in the achieved productionresults were stated. The organoleptic evaluation of meat however showed considerable differences in the intensity of aroma, smell and taste.

Opis: In recent years, immunocastration, a vaccination against gonadotropin releasing hormone, has been proposed as an alternative to surgical castration of intact male pigs without anaesthesia. However, the effects of immunocastration on metabolic changes, nutritional requirements and growth potential have not been quantified. Thus in the present thesis, the meta-analytical approach was used to quantitatively synthesize the effects of immunocastration and four studies were conducted to evaluate the effects of quantitative and qualitative feed restriction on growth performance, heat production and energy metabolism, carcass and meat quality. Results show that boar taint compounds are dramatically reduced in immunocastrates, still they remain slightly higher than in surgical castrates. Immunocastrates are less feed efficient, fatter but grow more rapidly and may have better meat quality than entire males. Compared to surgical castrates, immunocastrates have superior performance with no difference in meat quality. It is more economical to fatten immunocastrates than surgical castrates, but production costs and carcass quality are less favourable than in entire males because of the huge increase in voluntary feed intake during the weeks preceding slaughter. Applying quantitative feed restriction after active immunization did not significantly affect growth performance or carcass composition; however, restrictively fed immunocastrates were closer to entire males, whereas ad libitum fed immunocastrates were closer to surgical castrates. Meat quality is also unchanged by the restriction. However, higher incidence of carcass lesions in restricted immunocastrates together with higher plasma cortisol level indicates more aggression prior to slaughter and can be considered as a negative aspect of the quantitative restriction. Total heat production, assumed to be the major factor contributing to the differences in feed efficiency of pigs, is changed after the immunocastration. Additional energy retained due to higher feed intake is directed towards lipid deposition. Increased fatness of immunocastrates is a result of increased daily lipid deposition caused by higher energy intake, lower fasting heat production and improved energy retention. Hence, dietary energy intake should be limited after immunocastration. Moreover, according to the results of the nitrogen balance study, dietary crude protein content could also be decreased. By reducing net energy concentration of the diet up to 10 % using higher fibre content, similar energy efficiency (gain to net energy intake ratio) may be achieved, with an advantage in terms of reduced lipid deposition, and no effect on growth rate after effective immunization. This is particularly important when immunocastrated pigs are fattened to higher body weights, i.e. when longer delays between full immunization and slaughter are practiced.

Opis: In this paper, based on the analysis of official FAOSTAT and EUROSTAT data on poultry meat for 38 European countries for years 2007 and 2009, two hypotheses were examined. Firstly, considering four clustering variables on poultry meat, i.e. production, export and import in kg/capita, as well as the producer price in US $/t, using descriptive exploratory and cluster analysis, the hypothesis that the clusters of countries may be recognized was confirmed. As a result six clusters of similar countries were distinguished. Secondly, based on multiple regression analysis, this paper proofs that there exists the statistically significant relationship of poultry meat production on export and import of that kind of meat, all measured in kg/capita. There is also a high correlation between production, as a dependent, and each of two independent variables.
