Locomotory, metabolic and alimentary disorders in Holstein and Czech Fleckvieh dairy cows – comparison of occurrence in the Czech Republic

Popis výsledku v původním jazyce

Proceedings of 17th International Conference on Production Diseases in Farm Animals (ICPD), 27. – 29. 6. 2019, Bern, Switzerland – abstract. The first national survey covered all diseases/health disorders occurring in Czech dairy cows. The data were gathered retrospectively from farmers via on-line survey from July 2016 through June 2017. The 46% of farmers who responded owned 78% of dairy cows in Czechia. We gathered 27 common health traits. The farmers reported 411,949 health events on 956 farms. Data were edited and assigned according to the breed to C (≥75% share of Czech Fleckvieh; 96,909 lactations, mean 279 per herd) and H (≥75% share of Holstein; 165,922 lactations, mean 346 per herd). Cows of these breeds were kept on 916 farms (91.2% of these farms with >80% lactations of one breed). This study evaluated the occurrence of digital dermatitis, interdigital phlegmon, interdigital hyperplasia (tyloma), ulcer (of the sole area), white line abscess, lameness, parturient paresis, downer cow syndrome, primary clinical ketosis, displaced abomasum, all locomotory, metabolic and alimentary disorders. To identify the farms with incomplete data, each farm with more than 20 evaluated lactations (92.8% farms) had to report at least 1 record of the particular health disorder to be included in the evaluation of the disorder. Reported occurrences were expressed as lactational incidence rate LIR (number of affected lactations / number of lactations at risk) x 100 and at the first occurrence in lactation the parity was evaluated. For editing the database and calculations the SAS 9.4 software was used. C and H lactations lasted 317±86 and 340±94 days, milk yield in lactations which lasted >240 DIM reached 7,627±1,961 and 10,100±2,025 l milk and the mean parity was 2.78±1.66 and 2.33±1.36, respectively. Many farms failed to report some diseases. In evaluation of locomotory disorders were included 79% C and 82% H herds, but in evaluation of individual locomotory disorders only 18-52% C herds (tyloma-lameness) and 20-55% H herds (tyloma-ulcer). This study shows that H cows had a significantly higher LIR for four individual diseases, for all locomotory, metabolic and alimentary disorders but lower LIR for white line abscess and parturient paresis. Whereas the same level of LIR was found in interdigital phlegmon and ulcer in primiparous C and H cows, the pluriparous C cows had lower LIR than H cows– except ulcer in the 2nd lactation. LIR for interdigital phlegmon was in 1st lactation higher than in 2nd in both breeds (P<0.001).
