Abstract

100 Holstein–Friesian cows were enrolled from dry perod to six months of lactation. The cows were selected from
population of dry cows, LS 3 or lower, free from other serious diseases. A 27 cows in our research developed
lameness during lactation. Retrospectively we determined which were the critical values of milk production,
composition of produced milk and blood metabolic parameters in early lactation which increase risk for lameness
developing. The ROC analysis show that cows with milk production of ≥36.00 kg., milk fat of ≥4.24% and milk
proteins of ≥3.47% in the third month of lactation (70-80. days) are more likely to develop lameness. The tested
values show that the decline in the concentration of milk urea increases the specificity and decreases sensitivity
for detection on the lame cows. Cows with milk urea concentration of <3.95 mmol/l at 6-8 week of lactation are
more likely to develop lameness compared to cows with a lower concentration of milk urea .The blood metabolite
parameters show significant predictive value for lameness developing. The cows with glucose ≥3,91 mmol/l, LDH
≥2123 U/l, ALP ≥92,86 U/l, total cholesterol <2,6 mmol/l, triglycerides concentration <0,11 mmol/l, BHB
concentration ≥0,90 mmol/l, and urea 3,30 mmol/l, at onset of lactation were much more likely to develop
lameness during lactation. In conclusion milk production, composition of produced milk and blood metabolite
parameters in early lactation can be used for prediciton of lameness event at dairy cows.
