[The ecopathologic approach to the study of the relationship between nutrition and health in the dairy cow].
An ecopathological approach for examining nutrition-induced health disorders in dairy herds in France is described. Bovine dairy herds were surveyed for 4 yr to detect nutritional risk factors that discriminated between high and low disease incidence rates for retained placenta, milk fever, calf perimortality, metritis, liver disorders and infertility. In the cow, preventive feeding helps avoid nitrogen overnutrition, and reduces the requirements of Ca in the late gestation period, gives a satisfactory balance in polyunsaturated fatty acids before calving. The absence of feedstuffs including toxic components and a feeding system with few feedstuffs and few diet changes are also beneficial factors.
