Evaluation of health traits of dairy cows in the Czech Republic, poster at 69th Annual Meeting of the European Federation of Animal Science 27.-31. 8. 2018, Dubrovnik, Croatia

Original language description

Book of abstrakts of the 69th Annual Meeting of the European Federation of Animal Science, 27.-31. 8. 2018, Dubrovnik, p. 251. Health problems, mainly reproduction disorders and udder diseases, are the most frequent cause of culling dairy cows in the Czech Republic. Selection indices of Czech dairy cattle already include indicator traits, such as somatic cell count or legs and udder conformation. Though, genetic evaluation of direct health traits would enable more precise selection on disease resistance. We have no continuous national system to collect and to process the health data currently. Data on medical treatment based on veterinary prescription have to be recorded and stored by farmers. The purpose of our study was to determine if these data are usable for genetic evaluation. We gathered the data of 27 common health traits retrospectively from farmers via on-line survey for time period from July 2016 through June 2017. To differentiate the farms with incomplete data, each herd with more than 20 lactations was required to repot at least 1 record belonging to particular health trait to be included in its evaluation. Reported health events were expressed as lactational incidence rate LIR (number of affected lactations / number of lactations at risk) x 100. The study covered 281,914 cows (76% of Czech dairy cows). One or more disorders were reported in 55% of cows. Clinical mastitis was the most common trait (LIR 17.9%) followed with metritis (10.9%) and cystic ovary disease (10.9%). Digital dermatitis (5.1%) and interdigital phlegmon (3.5%) were the most frequently reported locomotory apparatus disorders. Primary ketosis (2.2%) was the most frequent of clinical metabolic diseases. Our study showed that not all farmers reported all health events, when more than 70% of them sent data on reproduction disorders and udder diseases, above 50% reported on orthopaedic disorders and less than 30% on metabolic diseases. Despite certain limitations, the data from farmers are with caution and after careful editing usable for further processing and genetic evaluation of cattle health. The study was supported by the projects QJ1510217 and MZE-RO0718 of the Ministry of Agriculture of the Czech Republic.
