Plants seem to be rather defenceless, they are unable to do motion, have no nervous system or immune system unlike animals. Besides this, plants do have hormones, though these substances are produced not in glands. In view of their complexity they lagged behind animals, however, plant organisms show large scale integration in their structure and function. In higher plants, such as in animals, the intercellular communication is fulfilled through chemical messengers. These specific compounds in plants are called phytohormones, or in a wide sense, bioregulators. Even a small quantity of these endogenous organic compounds are able to regulate the operation, growth and development of higher plants, and keep the connection between cells, tissues and synergy beween organs. Since they do not have nervous and immume systems, phytohormones play essential role in plants’ life. Orv. Hetil., 2014, 155(26), 1011–1018.

Both antibiotic and probiotic feed additives are in independent use in the pig industry. The modes of action of these two groups of growth-promoters remain to be established. The present study was designed to investigate the effect of inclusion of an antimicrobial feed additive (Tylosin) or a probiotic (ProbiosR, Pioneer Overseas Corporation) on growth rate and the development of intestinal structure and function of pigs from birth to 80 days of age.
