PARASITIC DISEASES OF THE DIGESTIVE ORGANS OF WEANED PIGLETS IN INTENSIVE BREEDING AND MEASURE TO CONTROL

Parasitic infections are constant companions of pig production, regardless of the method of keeping. Caused by several parasitic species, they threaten the health of animals and cause significant economic losses due to lower growth, reduction in body weight of fattening animals and loss of daily gain, poorer feed conversion, and finally, a problem appears in the slaughterhouse industry in the form of confiscation or conditionally usable meat. During research carried out in the period 1991-2021, the most common occurrence of protozoan infections in weaned piglets is that we found the average presence of protozoa Balantidium coli (95-100%), Cryptosporidium sp (17-32%), Eimeria perminuta (27-31%) ), E. debliecki (3-24%), E. polita (4-9%) and Isospora suis (3-13%). Helminth infections Ascaris suum (39-41%), Oesophagostomum dentatum (6-8%), Strongyloideus ransomi (1-17%) and Trichuris suis (1-7%) were also found. The planned application of parasitological, zootechnical and biosecurity measures is crucial in protecting the health of pigs and the success of production.
