The investigations conducted on 4 lots of gestating and parturient sows and their progeny have been aimed to determine the risk factors that lead to the occurrence of toxicosis in the sows-mothers and, as a consequence, cause toxic gastroenteropathy in new-born piglets. Clinical examination included the determination of the general status (body temperature, cardiac and respiratory frequency, behaviour, etc.) and the detailed investigation of the functional state of digestive, cardiovascular and urinary systems. Since the first days after parturition the sows kept in industrial complexes showed a subfebrility state, in some cases the maximum limit reaching the level of 39,9±0,2630C (P<0,05). If the rectal temperature is over 39,50C the sows are considered as sicks and need an urgent treatment. In the majority of sows there were obvious changes in electrocardiophysiological activity of myocardium (T wave was triangular shaped and was reaching a size of 0,6-0,8 mv) which is typical for toxicosis. Paraclinic investigations demonstrated the presence of essential changes concerning the endogenous intoxication markers in the piglets with colostral toxicosis. The content of medium-weight molecules in the blood serum of these piglets was by 41,07% higher compared with their healthy congeners (M±m=18,17±0,23 u/c and 12,88±0,31 u/c respectively); p<0,001), the content of necrotic substances – by 52,5% higher (M±m=1,83±0,14 c/u and 1,2±0,22 c/u, respectively; p<0,05), while the carnosine content was reduced by 12% (M±m=78,35±3,15 μmol/L and M±m=99,13±4,6 μmol/L, respectively; p<0,01).
