In modern pig husbandry for meat production, various feed mixtures are used with various nutritive supplements added. From the economic aspect, one of the major issues is the ratio between the live body weight gain and the feed intake (feed conversion). To provide healthy nutrition for people, it is not advisable to use nutritive antibiotics in pig feed (a ban on their use has already been imposed in some countries), while the concentration of N, Zn, Cu and Cd in pig farm waste poses a special threat to environment. The basic issue is how to reduce the quantity of feed used per each kg of weight gain, while diminishing the use of environmentally hazardous substances affecting people's health. To achieve optimum results, we will try to develop and to apply recently discovered and already tested bioelectromagnetics methods. They will be used in testing the physiological condition (e.g. stress) of growing pigs and in preparing optimum feed mixtures. A larger complex of such stimulation and detection methods has been developed in our basic research projects and some other applicative fields. We intend to develop a system of establishing the biological value of the feed via digital electrophotography, a system of monitoring the pigs' physiological condition by means of differential contrast photography and to improve the feed conversion through various types of magnetic stimulation of feed, water and pigs. The anticipated results are: an improved feed conversion, a positive influence on the pigs' state of health, and moreover, a possibility of reducing the use of certain disputable feed additives.
