**Assumptions:

  1. Economics adapted from P. H. Robinson, Ph.D., Dept. of Animal Science, UC Davis
  2. Locomotion scoring adapted from Sprecher et al., 1997, Theriogenology 47:1178-1187
  3. Estimated milk production losses for cows with the following locomotion scores:

    eg.

    		 Locomotion score 3: 5.1% milk loss
    Locomotion score 4: 16.8% milk loss
    Locomotion score 5: 36.0% milk loss
  4. Lost revenue underestimated as it does not account for lost income due to
    decreased fertility as the result of lameness. See Lameness Cost - Guard for
    a more complete list of costs associated with lameness.
