Testing Programs

We have testing programs to best meet your needs and will customize a program for any size herd and set-up. We guarantee seamless data transfer to breed associations and offer official test types to meet the Council on Dairy Cattle Breeding (CDCB) requirements.

When you choose a Processed Test program the data is processed through DRMS. Processed Test data flows to CDCB and breed associations, and a backup of your data is stored. Alternatively, the Non-Processed test provides only the basic data of milk weights, components, and SCC and is returned to you as a CSV file.

Processed Tests

Official, supervised

A trained and certified DHI Specialist is on the farm for one milking to collect milk weights and samples. Weights may be gathered from an automated milk recording (AMR) device.


CentralStar supplies meters and sample vials, so you can collect samples and record weights. DHI Specialist picks up samples and sends them to lab for processing. Weights and samples can be taken from one, two, or three milkings at no additional charge.

Robotic parlor

DHI Specialist sets up and uses the Ori-Collector, which is approved for use with DeLavel, Lely, Galaxy, and other robotic systems. For sample collection independent of a DHI Specialist, contact CentralStar for milk sample shuttle rental rates and availability.

    Automated milk recording update

    Milk weights are collected from an AMR device in a parlor and sent to DRMS for processing. Butterfat and protein are estimated. This test type is used in conjunction with the weighed and sampled test types.

      Non-Processed Test

      The DHI Specialist collects milk samples and can record milk weights if requested. Samples are evaluated at a CentralStar lab and a CSV file containing animal ID, milk weight (if requested), sample number, components, and SCC data are provided. Records are not processed through DRMS.

      Milk Sample Analyses

      Milk samples can be analyzed for a variety of production, disease and health-related traits. Samples submitted through routine DHI include analysis for components and SCC, with the option to add other testing at an additional cost.

      • Components (fat and protein)
      • Milk Urea Nitrogen (MUN)
      • Somatic Cell Count (SCC)
      • Solids not fat (SNF)
      • A1/A2
      • BLV
      • BVD
      • Johne’s disease
      • Mastitis
      • Neospora
      • Pregnancy

      Samples can be submitted between routine DHI testing direct to the laboratory via mail, drop-off, or delivery service. Contact the CentralStar lab nearest you to establish a program.

      Transition Cow Report (408)

      Provides analysis of key transition period metrics including dry periods, first milk weight, fat to protein ratio, udder health, reproduction, turnover, and distressed cows. Includes goals for each metric which are set at the level achieved by the top 10% of herds similar in size to your herd.
