Abstract

The study presents basic description and analysis of occurrence of treatment records at 20 common health disorders/diseases monitored in 289 802 dairy cows in the Czech Republic. The data were provided by farmers on a one-time basis from 1 183 herds and covered the season from July 2015 till June 2016. 55.1% of cows were marked as untreated, while in 44.9% of cows there was recorded at least 1monitored disease. The most frequent disease was mastitis (19.8% treated lactations, i.e. lactational incidence Lir), followed with metritis (11.3%) and claw and locomotor diseases (11.0%). Treatment of metabolic disorders was rather seldom (Lir 1-3.2%). Lir mostly grew with parity, mainly for parturient paresis and mastitis (from 0.4 and 14.7% on 1st lactation to 7.1 and 26.4% on 5th+ lactation). The associations with individual milk yield of cows and the size of the herd (grouped to classes) was not so distinct and unambiguous. The highest Lir was predominantly in the highest class with milk yield over 11 000 kg per lactation (+4.2% for cystic ovaries, +3.1% for metritis and +2.1% for subclinical primary ketosis; compared to the lowest class with yield
