Health-control costs were described in 248 dairy farms in Pays de la Loire
(France) in 1995/97. Total costs, excluding mandatory programs, averaged 85
.70 euro/cow-year (61.2, 8.8, 9.2, 3.5 and 3.0 for cows, heifers, calves, g
eneral hygiene, and herd-level infectious disease control, respectively) an
d 1.14 euro/100 kg milk. Cow disorders associated with the highest costs (i
n euro/cow-year) were: udder (26.76), metabolic (6.63), reproductive (5.27)
, peripartum (4.89), locomotor (2.28) and digestive (2.21) disorders. In ad
dition, 5.43, 4.15, and 3.38 euro/cow-year were spent on nutritional produc
ts, herd-health and fertility programs, and parasite control, respectively.
In heifers and calves, respectively, major costs were for parasite control
(7.05 euro/cow-year) and digestive disorders (6.70 euro/cow-year). For all
costs, large variability existed between farms. One farm out of four had l
ow costs for all disorders, among which only half had low incidences for al
l disorders. Variable health status occurred at all levels of costs. Propor
tion of preoccurrence costs was independent of total costs. A trend in incr
easing costs with dairy intensification was observed, assumed to result par
tly from different health management options. Costs/kg milli were significa
ntly higher in non-Holstein than in Holstein farms. In all farming systems,
large variability of health-control costs suggested that there was potenti
al for improvement of health management. (C) 2001 Elsevier Science B.V. All
