Data Collection Rating (DCR)

The accuracy of lactation records from a wide variety of testing plans can be compared using a DCR.  The end-user determines the value to place on records coming from individual dairy producers.  A weighting factor is applied which tells how much information that animal/herd will contribute to the evaluations. The greater the number of supervised DHIA tests a dairy has within a year, the greater the DCR ascribed to that record.  Minimum DCR's for awards programs such as ADGA's may be required.

You can keep track of your doe's DCR by using the CDCB query site (pedigree/lactation information).  However, realize that a fully supervised verification test may not always be reflected in the DCR score provided.  It has to be noted as such by your record center to do that.  If noted, a VT will always add to the total rating if you are on an ITP or Owner Sampler plan because it changes the percentage of Owner Sampler information (drops it from 100%).

 The following is to give a GENERAL idea of the DCR that can be earned:
