DHIA Record Services
Supervised or Unsupervised (Owner Sampler) Testing
Supervised Testing: A trained and certified Field Technician comes to your dairy, records milk weights and takes a milk sample from each cow for component analysis. Components are traditionally fat and protein, but can also include somatic cell (SCC) and/or milk urea nitrogen (MUN) testing. The Field Technician also records all changes in status information (fresh, aborted, dried-off, died or sold) and reproductive information for each cow.
Unsupervised Testing (Owner Sampler): A trained and certified Field Technician will deliver needed testing equipment to your dairy. With this lower cost option, the member takes all their own samples and supplies the data to the Technician. The Field Technician will pick-up the samples and record herd information and send this to the laboratory for analysis and processing.
Types of Testing Programs
All milkings are weighed and sampled on test day.
Also called A-P testing, this service allows a member to test their herd only one milking a month. Using conversion factors, milk weights and components are adjusted to calculate production in a 24 hour period.
This program is for those only wanting a component results with no milk weight or other data provided.
Types of Record Programs
Traditional Records processed through a Processing Center
The Technician uses software to collect all on-farm data, including animal identification, calvings, breedings, pregnancy checks, dry offs, and milk weights at one or more milkings. Component samples may or may not be taken. Collection of the milk weights and samples may be done by the Technician or by labor supplied by the dairy. The data is forwarded to a processing center, and reports generated by the processing center are mailed back to the dairy. Cow lactation records are forwarded by the processing center to Animal Improvement Program Laboratory (AIPL), and the records may be used to calculate genetic evaluations.
The Technician uses the field technician version of Dairy Comp 305 (FTECH) at the dairy, and collects all on-farm data, including calvings, breedings, pregnancy checks, dry offs, and milk weights at one or more milkings. The Technician leaves reports and work lists at the farm on test day. Milk weights are factored to represent 24 hours. If component samples are taken, the laboratory sends the results in a separate report to the dairy after the samples are processed.
The dairy hires a Dairy One DHIA technician to come to the farm and take milk weights and/or milk samples. The dairy can also provide their own labor, with the Technician delivering the meters and sample vials to the farm. The milk weights are left on the farm in written form, and the components are mailed back to the farm from the laboratory.
Tech Only for Dairies with on-farm Dairy Comp 305 or Scout
Those dairies that use one of these two software programs can give a daily backup to the Technician, and receive milk weights and/or components back in electronic format to load directly into their software.
Labor Efficient Records
Dairies with electronic milk meters and on-farm Dairy Comp 305 or PCDART may be eligible to use labor efficient records. Typically a Technician collects milk samples every other month or every three months, and on the test days with no component samples, the dairy uploads their data directly from their own software. The data is forwarded to a processing center, and reports generated by the processing center are mailed back to the dairy. Cow lactation records are forwarded by the processing center to AIPL, and the records may be used to calculate genetic evaluations. National DHIA quality certification requires that the electronic meters be certified every year for accuracy.
The dairy can rent our Surge meters for 24 hours at a time.

Records Processing Centers
The processing center is where records are sent in order to be edited and sent on to AIPL , breed associations and USDA. This data is then used in proving bulls, and for research and evaluation purposes.
Dairy One is the only DHIA in the United States to offer all processing center options. Choices are typically geographically influenced however every producer has the option to select the processing center that best meets the need of their individual farms.
