BIOCHEMICAL PROFILE OF PREGNANT SOWS BY T-2 MYCOTOXICOSIS
A comparative characteristic is cited of protein, fat, carbohydrate and mineral metabolism of healthy and pregnant sows with clinical signs of chronic Т-2 micotoxicosis. An evaluation is given of an acid-base balance, functional activity of a liver, cardiac muscle, kidneys and pancreas of healthy and diseased animals. Studies have found that in 2012 at livestock enterprises of Sverdlovsk region a mycotoxin contamination of forrage for farm animals was 65.8 % exceeding maximum permissible levels: DON 2.07 times, T-2 toxin 2 times, aflatoxin 3 times. Priority pollutants were T-2 toxin and DON. Chronic T-2 myco- toxicosis has a very negative effect on metabolic processes in the body, as well as on the functional capacity of vital systems of pregnant sows. As practice and experiments show, there is no safe levels of mycotoxins, it all depends on multiplicity of poison admission and a dose. Liver and heart muscle undergo the strongest toxic load. Biochemical studies revealed that for sows with clinical signs of T-2 toxicosis a characteristic hepatic impairment is a hepatodepressive, cytolytic as well as cholestatic syn- drome. In a heart muscle myocard is the most severely affected. It is found that the major biochemical markers at T-2 toxicosis are: total bilirubin, cholinesterase, gamma-glutamyl transpeptidase (GGT), LDH, CK-MB and CK. It is noted that changes, characteristic to diseased sows, sre peculiar to clinically healthy animals, only to a lesser degree.
