21 Transition Cow Index MD Milk recording for dry cows! 44% of herds use TCI «Tip of the Iceberg» Healthy Cows Subclinical Cases The Iceberg! Clinical Cases TCI of 1,000 represents an extra $450 in the current lactation.

22 Cost of Ketosis: $354 per case 61 % of Quebec clients use Ketolab

23 Milk Ketone Testing by FTIR Advantages Suitable for whole herd screening Simple for the producer Low cost Can be performed on regular intervals Rapid results Disadvantage: With monthly testing, not all cows are tested in the period most at risk

37 Valacta s Strategy for Ketolab Ketolab is used as a screening tool to evaluate ketosis prevalence at the herd level Ketolab is not an individual diagnosis tool High BHB does not necessarily mean that this specific cow is sick, but it is an important risk factor for other problems

38 Ketolab in Quebec >70% of Valacta herds have registered for the service >55% of the samples analysed each month 88% of farms using advisory service 57% of farms not using advisory service
