[Continuous ecopathological survey. 1. Classification of the pathology observed in dairy cattle breeding].
Observations were made during a continuous ecopathological survey on 3,216 dairy cows from 90 dairy farms and localised in six French departments, over a three year period (1978-1981). The pathology described for cows and their calves was classified according to the frequency of each disease and/or symptom. The reasons for culling as well as those for mortality were also classified. The pathology of reproduction and the mammary gland in the dairy cow and the digestive pathology and mortinatality of calves appear to be the major pathological problems.
