Small Molecules of Natural Origin as a Source of Antimicrobial Agents in Pig Breeding - Review
|Články v odborných časopisech
The use of antibiotics is currently limited within the framework of the prevention of the infectious disease in farm animals in the EU. Formerly used antibiotic growth stimulators markedly enhanced the quality of animal breeding and decreased the incidence of infectious diseases. After their ban, the new substances, which do not cause a possible resistance to pathogenic agents, are searched. One option is to use the small molecules of natural origin, particularly the primary and secondary plant metabolites. It is possible to consider the use of a new generation of cationic peptides isolated from plants or animal and bacteriocins. The use of these substances in the pig breeding is directed into the feeding stuff in a form of additive compounds, whose aim is to prevent the development of microbial infection in GIT and the area of abdomen, increasing the immunity of animals and decreasing the inflammatory processes in boar genitals. The second area is the application of these substances in the cryopreservation of boar semen and into the extenders for the short-term storage of semen prepared for AI. According to the EU recommendation, a substantially higher attention must be paid to the research of natural substances in agricultural sphere.
