Epidemiology of Production Diseases in Dairy Cows on Czech Dairy Farms.
Original language description
In 12 herds of Holstein dairy cows the prevalence of production diseases was monitored, throughout the calving-to-calving interval. The most serious health problems were observed at parturition and during the first 30 or 60 days of lactation. The best health status was found during late lactation and in dry cows. Fat cow syndrome was diagnosed in cows prior to calving, (up to 40%). Deficiency in phosphorus, selenium, vitamin E and beta carotene was found in all herds. Hepatic steatosis was observed in isolated cases. Hypocalcemia was diagnosed in cows during delivery - parturient paresis in 2 to 6% of multiparous cows after delivery, subclinical hypocalcaemia in 52% and excessive body fat mobilization in 82% of dairy cows. In the postpartum period (up to 30 days of lactation) high prevalence of hepatic steatosis was observed in 48 to 62%, subclinical ketosis in 15 to 24%, subclinical hypocalcemia in 32.5%, subclinical hypophosphatemia in 10.5% and subacute ruminal acidosis (SARA) in 15 to 28%. In the subsequent period, the above mentioned metabolic disorders persisted, but their occurrence and severity was gradually decreasing. Similarly, the occurrence of copper and selenium deficiencies was decreasing. However, deficiencies in vitamin E and beta-carotene persisted. The occurrence of the above mentioned metabolic disorders was accompanied by increased occurrence of diseases affecting body organs. Notably, it was metritis with the prevalence in 26 to 80% in some herds and mastitis with the prevalence in 6 to 18%. Laminitis and abomasal displacement were also observed. Abomasal displacement occurred primarily in Holstein cows with the incidence rates ranging between 2 and 8% in different herds. Fertility levels were very low. Pregnancy rates after first AI were in the range of 24.5 - 36.2% . The culling rate of cows was 34.46%. The main reasons of culling were health-related, including infertility (79.7%)
