Sažetak

The behavior of pigs can be divided into several categories, which include maternal behavior, aggressive behavior, sexual behavior, feeding behavior, and various other forms of emotional behavior. Domestication has caused many changes in the original behaviour of boar, such as in reproductive and sexual behaviour, and has lead to a general increase in social tolerance between animals. Further modifications in behaviour are also possible, as suggested by the optimization of environmental factors which affect maternal behavior. The behaviour of a sow after farrowing appeared as a consequence of natural selection for protection of piglets from predators in the wild boar population, and affects the survival of piglets and the longevity of the sow in breeding. The behavior of the sows which includes the protection of the piglets from predators appears as a consequence of natural selection in the wild boar population. Familiarity with the molecular mechanisms which determine the patterns of behavior enables understanding of behavioral problems such as aggressiveness and helps the improvement of the well-being of pigs. Research conducted on pigs has determined that there are regions on chromosomes 2, 6, 10, 14, and 15, and chromosome X which can explain the genetic aspect of appearance of some behavioral patterns in sows. The goal of this paper is to illustrate the behavioral patterns appeared in the populations of domestic breeds of pigs and their genetic aspects, which knowledge may provide some help in improving the production qualities and creating higher economic gain during production.
