Laktationsinzidenzen von Produktionskrankheiten bei Fleckviehkühen in sechs bayerischen Milchviehbetrieben


Bijmholt, S; Müller, K; Leiding, C; Hoedemaker, M; Bollwein, H; Kaske, M (2012). Laktationsinzidenzen von Produktionskrankheiten bei Fleckviehkühen in sechs bayerischen Milchviehbetrieben. Tierärztliche Praxis. Ausgabe G, Grosstiere/Nutztiere, 40(6):347-358.

Abstract

Objective: The aim of this study was to assess lactation incidences of production diseases in German Fleckvieh cows. Material and methods: Investigations were carried out on six dairy farms (mean milk yield of herds 2008: 7834 ± 708kg milk [mean ± SD]) in Bavaria. All farms kept the cows in free stall barns and fed them a total or partial mixed ration based on grass silage and corn silage. In total, 116 cows and 58heifers were examined daily for 14days post partum and treated - if necessary - according to standard protocols. The acquisition of data for diseases in the further lactation was carried out by regular visits to the farm as well as communication with the herd manager and the farm veterinarian. Results: Pluriparous cows suffered more frequently from production diseases (milk fever, retained placenta, clinical ketosis, abomasal displacement, metritis, endometritis, ovarian cysts, mastitis) than primiparous heifers: 33.3% and 46.4% of pluriparous and primiparous cows, respectively, remained clinically healthy, while 24.8% and 30.4%, respectively, suffered from one production disease during the first 2weeks of lactation; more than one production disease was diagnosed in 41.9% and 23.2% of pluriparous and primiparous cows, respectively. The lactation incidences of production diseases varied considerably among pluriparous cows of the six farms: retained placenta 16.8 ± 13.2%, milk fever 15.1 ± 7.0%, clinical ketosis 16.8 ± 12.4%, metritis 3.8 ± 3.1%, abomasal displacement 1.1% (median 0.0; 0.0/0.0%), endometritis 11.7 ± 7.0%. Mastitis affected 56.0 ± 7.4% of the pluriparous cows, which experienced 1.7 mastitis episodes on average. At least one follicular cyst was diagnosed among 28.4 ± 8.6% of the cows. Lameness affected 18.5 ± 13.5% of pluriparous cows and heifers during the first 2 weeks of lactation. Conclusion: The lactation incidences of production diseases did not significantly differ from reference values reported for Holstein Friesian cows except the lower incidence of LDA among German Fleckvieh cows. The results indicate that the farm management affected lactation incidences of production diseases to a greater degree than additional factors, such as the breed of the cows.
