  This study was conducted to investigate the effects of supplemental n-6 and n-3 fatty acids on sow’s milk fatty acid composition during the lactation period and on reproductive efficiency of sows in the subsequent gestation period. Data were collected on a total of 213 DanBred sows (108 control and 105 experimental) representing parity of 2–7, respectively. Control and experimental sows were placed in the same housing conditions during lactation and gestation period. Control group received 6.3 g of sunflower oil (SO) per kg feed as n-6 fatty acid supplementation, whilst experimental animals received the same amount of fish oil (FO) as n-3 fatty acid source. Diets were corn meal-extracted soybean meal based. The experiment was conducted in one replication as being a part of a longer and more comprehensive trial. It was found that the consumed long-chain polyunsaturated fatty acids (LC-PUFAs) appeared in the sow’s milk and changed its fatty acid profile. With this alteration, the n-6/n-3 ratio of experimental (FO) sows’ milk were narrower than in SO group (SO: 13.82 vs. FO: 5.89). The benefits of n-3 fatty acids supplementation were evident for the subsequent reproduction cycle, when experimental sows heated more reliable and earlier than control (weaning to oestrus interval: SO: 5.86 vs. FO: 4.48 days). Only 2.33% of experimental sows (FO) did not heat within 7 days after weaning, but this was 12.36% in the control group (SO). The present study requires further research to evaluate the effect of n-3 fatty acids on maintenance of pregnancy and improved subsequent litter size.

  Nowadays, the socio-economic role and function of universities as well as their relationship with the industry, are more than ever in the focus of both the political and the academic spheres. The importance of knowledge and technology transfer is increasingly stressed in various economic development plans and strategies. The increased interest is due to the fact that universities are located at the crossroads of education, research and innovation, which might be crucial for the country's economic competitiveness. The commercialization of university research results is a well-defined task of technology transfer offices. Measuring the efficiency and successfulness of such offices is a difficult, but not impossible task. The present article aims to analyze the existing literature on measuring the efficiency of technology transfer activities and to introduce the most commonly used measuring methods of effective technology transfer. The article attempts to answer the question how to measure the efficiency of technology transfer by reviewing the available international literature and by analyzing secondary data.
