Evaluation of Health Traits in Czech Dairy Cows

Original language description

Abstrakt in Book of abstracts, XXXIIIth Genetic Days 2018, 18.-20. 9. 2018, České Budějovice, 53-54. Genetic improvement of dairy cattle was focused on productive traits for decades, which has led to deterioration in functional traits, mainly fertility, disease resistance and longevity. Intensive selection for milk production has negative effect on reproduction and health, as highly productive cows often suffer from longer negative energy balance after delivery. Genetic evaluation of direct health traits is not well developed in Czechia yet. Although Czech farmers have to keep records of causes for medical treatment, these records have not yet been gathered on the national level. Our purpose was to determine if these data are usable for genetic evaluation. We gathered the data of 27 common health traits retrospectively from farmers via Q CZ on-line survey for time period from July 2016 through June 2017. We received response from 46% of farmers, which owned 78% of Czech dairy cows. Data were edited so that only lactations started between 1.7.2016 and 1.5.2017 were evaluated to keep a minimum period of 60 days to enable the disease/disorder to express. Data were divided according to breed of cow to C (≥75% share of Czech Fleckvieh; 64,989 lactations) and H (≥75% share of Holstein; 104,573 lactations). Diseases/disorders were grouped according to affected organ systems. Reported occurrences were expressed as lactational incidence rate LIR (number of affected lactations / number of lactations at risk) x 100. Reproduction disorders and udder diseases were the most frequent. Occurrence of foot and leg disorders seems to be underreported compare to other national studies. Reports on metabolic and digestive tract diseases were rather sparse. LIR of all groups of disorders were higher in H compare to C breed. Our study showed that not all farmers were able to report all health events. More than 98% of farmers reported on mastitis occurrence, above 80% of them sent data on reproduction and foot and leg disorders and about 68% on metabolic diseases. Despite certain limitations, the data from Czech farmers are with caution and after careful editing usable for further processing and genetic evaluation of cattle health.
