Abstract:
Very intensive expansion of breeding capacities, early weaning of piglets from inadequate microclimatic conditions, and
inadequate nutrition in different production categories caused the appearance of production-related technological
diseases. Diseases of the digestive organs are a significant part of pig pathology. Of the enteric diseases, great importance
belongs to dysentery. It is characterized by long-term germination and a large number of vectors. Two diseases that were
previously considered to be atypical forms of dysentery, resulting from a shortened period of medication and resistance
of the causative agent to an exemplary antibiotic, today appear as separate entities. The first is so-called proliferative
enteropathy, and the second is spirochaetal colitis. Both of these diseases are present in pig herds with different
management, often in pig herds with high health status, after the elimination of the causative agent of dysentery. Coli
infections are present mainly in weaned piglets and appear in the second week after weaning. In our conditions, the disease
is diagnosed on the basis of clinical symptoms, rarely on the basis of pathomorphological changes. On controlled farms
(5 commercial farms and 10 extensive breeding farms), a clinical examination of the herd of pigs was performed. Rectal
swabs were taken. We separated the sick animals into special boxes and monitored their health. The number of weaned
piglets in the weaned category was variable. The number of dead pigs in the fattening category is particularly surprising.
The aim of this review is to provide information on bacterial diseases of the digestive organs of weaned piglets in two
housing systems and to provide a solution.
