All of these management practices contributed (P<0.01) to the overall score (R2 values: disease prevention, 0.453; breeding, 0.415; feeding, 0.408; housing, 0.355; calf rearing, 0.329; sale-purchase, 0.275; milking, 0.272; and care management, 0.217). It was concluded that by knowing the adoption scores of 1 or 2 of the most important individual practices the overall total practice adoption scores can be predicted. 收起
