  Precision animal nutrition consists of meeting the nutrient requirements of animals as accurately as possible in the interest of a safe, high-quality and efficient production, besides ensuring the lowest possible load on the environment. This is facilitated by electronic feeding based on IT technology, an important but by far not the only tool of precision nutrition. In the present paper the following most important elements of precision nutrition are discussed: diet formulation, quality control of ingredients and compound feeds, reduction of the harmful effects of heat stress in pigs with different nutritional tools, application of the recent findings of the molecular genetics in animal nutrition, the relationship between genetics and animal  nutrition and reduction of the N and P excretion by nutritional tools.

  The effectiveness the use of new nutrient complexes is studied. It is set that a combination of nutrient complexes with organic and organicmineral nutrition background promotes to good growth and development of plants during the growing season, provides the best parameters of crop yield structure and the crop yield and economic efficiency of spring barley cultivation in the condition of the Eastern Steppe of Ukraine.

  The field research was set up on chernozem soil at the Látókép AGTC KIT research area of the University of Debrecen. The study focused on yield, water utilization, nutrient reaction and the amount of yield per kg fertilizer of corn hybrid NX 47279 in 2011 and 2012. Based on the yield results it can be concluded that the largest yield in 2011 was 15 963 kg ha^-1 at level N120+PK, while in 2012, the maximum yield amounted to 14 972 kg ha^-1 at level N90+PK. Surplus yield per kg fertilizer proved that in 2011 level N30+PK resulted in the highest surplus yield (42.3 kg kg^-1) compared to the control treatment. In 2012, yield growth was 18.0 kg kg^-1 compared to the control treatment. We measured at level N60+PK 17,5 kg kg^-1 compared to at level N30+PK, at the N90+PK 17,7 kg kg^-1 compared to at level N60+PK. level N30+PK kg kg^-1, 17.5 kg kg^-1 at level N60+PK and 17.7 kg kg^-1 at level N90+PK compared to the control treatment.

  Results of the regression analysis showed that the amount of nitrogen fertilizer was 117 kg ha^-1 in 2011 and 111 kg ha^-1 in 2012 in order to reach maximum yield. Doses of fertilizers above the amounts previously mentioned resulted in yield decrease. Our results indicated that in the drought year of 2012 the hybrid used available water more efficiently than in 2011. The hybrid produced 59 kg ha^-1 yield in 2012 and 51.9 kg ha^-1 in 2011 at an optimum nutrition level.

  In the last decades many researches were made to change the animal product food’s composition. The production of better fat-compound milk and dairy products became a goal in the name of health conscious nutrition. These researches were motivated by the non adequate milk fat’s fatty acid composition. There have been made researches in order to modify the milk’s fatty acids’ composition to reach the expectations of functional foods. With the optimal supplement of the feed can be increased the proportion of the polyunsaturated fatty acids and can decreased the saturated fatty acids. Row fat content of milk was not decreasing in the course of examination neither of the cold extruded linseed nor the whole linseed supplement as opposed to observations experienced by other authors. In case of monounsaturated and polyunsaturated fatty acids when supplementing with cold extruded linseed the most significant change was observable in the concentration of the elaidic acid, oleic acid, linoleic acid, alfa-linolenic acid, conjugated linoleic acid. In case of saturated fatty acids the quantity of palmitic acid and myristic acid lowered considerably. When observating the feeding with whole linseed the concentration of many fatty acids from the milkfat of saturated fatty acids lowered (caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid). The quantity of some unsaturated fatty acids was showing a distinct rise after feeding with linseed, this way the oleic acid, alfa-linolenic acid, conjugated linoleic acid, eicosadienoic acid. The aim of the study was to produce food which meets the changed demands of customers as well. The producing of milk with favourable fatty acid content from human health point of view can give scope propagate the products of animal origin.

  This study summarizes and compares the definitions and applications of functional foods from the viewpoints of the different societies. Provides an overview of the functionalities of foods based on the scientific approach of today’s Western – including Hungarian – cultures and the traditional Indian approach that dates back to the ancient times. Gives a short description and comparison of the basic concepts and background knowledge of functional foods according to these two worldviews.
