T-2 FUSARIOTOXICOSIS IN A CATTLE STOCK

Production disorders caused by T-2 mycotoxin have been reported in a high-yielding holstein-fresian dairy stock. Following the consumption of a feed containing mycotoxin, milk production decreased and-simultaneously-estrous cycles stopped. Besides, diarrhoea was also observed in the stock which was the most severe with bloody character in the group consuming daily 10.5 kg of fodder. Clinical symptoms ceased, milk production was restored the original level and cows showed estrous cycles as previously after the T-2 toxin containing feed was withdrawn. Exact chronology of production disorders caused by T-2 mycotoxin has been detailed (Table 2, Figure). Anorexia, "refusal of feed", than diarrhoea, (quite 30%) decrease of milk production, bloody diarrhoea and absence of estrous cycles were observed 24 to 48 hours after the uptake of T-2 mycotoxin. Diarrhoea ceased 4 days after the change of feed. The ovarial function and milk production normalised on the expiration of 9 and 11 days, respectively.
