To detect indices on the cause of getting sick immediately after calving and
death of some cow out of farm A, were investigated the cows which calved and

were performed, blood samples pairs were collected for in the future laboratory
examinations. A total of 29 cows which calved/aborted in January and 21 cows
which calved/aborted in February were investigated. The evolution of each cow
after calving or abortion was monitored and the data was recorded in tables. Diet
quality was improved by adding energy and vitamin-mineral supplements for the
pregnant and calved cows, because it was observed that in November-December
2007 the diet was deficient and it had a mycotic and mycotoxic load overt he
