 TriStar adds flexibility to production
records
TriStar is the Holstein Association's program for
administering production records, cow and herd genetic performance reports,
and recognition. The changes in the DHIA environment provide flexibility
to all users of DHI data. This added flexibility places responsibility
on the end-user of production data, including breed associations, to set
their own standards for the use of production records. To meet this need
Holstein Association USA has developed the TriStar program with three
levels of service, Premier, Deluxe and Custom
to meet the needs of all dairy producers.
Under TriStar production records are labeled with Stars and DCRs to indicate
the test program. The Stars and DCRs indicate the level of testing, the
amount of supervision and the subsequent accuracy of the record. Production
records are labeled under the TriStar system as follows: Premier (***), Deluxe
(**), Custom (*).
Data Collection Ratings (DCRs)
The DCR value indicates the amount and type of information included in
a production record. This value is affected by the frequency of testing,
percentage of milkings weighed and sampled, and the amount of supervision.
DCRs are calculated for both milk and components. Example test plans can
be found on the Data Collection Rating (DCR)
Example Test Plans Chart.
Publication of Records
Only production records from cows in herds enrolled in one of the TriStar
service options (Premier, Deluxe, Custom) are eligible for Official
Holstein PedigreesTM. Other qualifications for pedigree
publication include three supervised tests in the first 305 days of lactation,
a usable test within the first 90 days of lactation. Milk records must
have a milk DCR >=76 in order to be published on a pedigree, while fat
and protein records must have a component DCR >=70 in order to be published
on a pedigree. Production records that do not meet all the qualifications
for pedigree publication will be labeled 'NON' (meaning non-qualified
for pedigree publication).
Important Note
Records are labeled with stars to indicate the milk testing plan that
the record was produced under in addition to the service option a producer
is signed up for. This means that if a herd owner is enrolled in the Premier
option but the milk DCRs from their testing program only qualify for the
Deluxe option the record will be labeled as Deluxe and will not be eligible
for the same recognition as a Premier herd or animal.
Recognition Eligibility
To be eligible for the Progressive Genetics Award, and
Progressive Breeders RegistryAward, herds must be
enrolled in either the Premier or Deluxe Service options.
To qualify for the Locator List or Top
10,000 CTPI cows, a cow must be in a herd enrolled in the Deluxe or
Premier Option. These cows can have an impact on the breed, therefore
the higher minimum data collection requirements and record monitoring
are required.
Cows in herds enrolled in the Premier production records program are eligible
for State and National Leader Lists.
A cow's record must also meet the minimum DCRM requirement (93) to qualify
for the Milk Leader Lists. Separately, a cow's fat and protein records
must meet the minimum DCRC requirement (93) to qualify for the Fat and
Protein Leader Lists.
All cows enrolled in TriStar are eligible to be recognized as Gold
Medal Dam or Dam of Merit. Cows
that finish with over 200,000 milk lifetime and are in a Premier or Deluxe
herd will receive a Lifetime Production
Certificate.
Open Disclosure
To ensure we receive 305 day, 365 day, and complete records from the Dairy
Records Processing Center (DRPC), Deluxe and Premier herds processing
through a DRPC other than AgSource in Wisconsin should enroll on a DHIR
testing option. Deluxe and Premier herds processed at AgSource can give
their Holstein TriStar option to their DHIA Technician/Supervisor. ALL
TriStar herds should check with their DHIA Technician/Supervisor about
signing up for OPEN DISCLOSURE.
