IMPLEMENTATION OF VARIOUS REARING – SELECTION AND BIOTECHNOLOGICAL METHODS IN BREEDING OF PIGS

Object of the research will be genetic improvement of economically important traits by selection and based on estimated breeding value obtained using constructed selection indices, BLUP-AM and using the gain obtained from crossing of pig breeds i.e. lines. Also, for the purpose of increase of reproduction efficiency, the problem of seasonal infertility of sows will be studied by implementing modern biotechnologies. Object of research will also be defining of optimal model of sow nutrition in the first, second and the last third of gravidity. This will have direct impact on number of piglets produced per sow, consumption of food per produced piglet, but also on longevity. The presence and level of zearalenon and deoxynivalenol in animal food will be monitored continuously, in order to prevent entering into entire food chain of these contaminants posing risk for animal health. By implementation of various selection procedures, breeding-selection and biotechnological methods, production of more fatteners per sow annually is expected. Also, pigs would have more (56 - 58%) quality meat in their carcasses (pH>5.8) with higher content of unsaturated fatty acids. The effects of meat production from primiparous sows and low input fattening of animals of autochthonous breeds and crosses of autochthonous breeds and meat pig breeds will be determined.
