The DIGAD project Background of DIGAD Legal docs Data DIGAD contains Confidentiality Access data How to request data Supplying data Contact details

The Dairy Industry Good Animal Database (DIGAD) is a database that holds data for every recorded dairy cow in New Zealand. The DIGAD project is involved in building a database, animal evaluation models, and developing systems for certified herd testing providers to submit data. Access to the data held in DIGAD can be requested through DairyNZ, and data standards are in place to maintain the quality of data.

The DIGAD project

The Dairy Industry Good Animal Database (DIGAD) holds pedigree and performance data for every recorded dairy cow in NZ.

This database contains all the data required to operate Animal Evaluation (AE) and was established within DairyNZ on the 1 December 2014.

The key outcome of this project will be to transition the operation and maintenance of NZ’s dairy cattle animal evaluation system from LIC’s Animal Evaluation Unit to NZAEL, a wholly owned subsidiary of DairyNZ.

Achieving ongoing genetic gain has been a cornerstone of the New Zealand dairy farmers’ competitiveness. It has been estimated that genetic improvement of dairy cattle contributes $300 million in profit, to the economy per annum. The DIGAD (Dairy Industry Good Animal Database) project is designed to help lift that contribution even further.

The DIGAD work is one of the most substantial database projects undertaken since herd records were first computerised (in the mid-1980s). It was initiated following recommendations in the Anderson Report in 2008, which provided a review of the New Zealand herd improvement industry.

The project has allowed us to identify a better method of processing fertility and body condition score data, which increases the accuracy of the corresponding breeding values (these benefits were realised in 2016).

Industry collaboration is significantly contributing to the seamless transition of a dairy farmer’s perspective, given the complexity of the data and systems involved.

This project involves a number of phases:

  • Phase 1: Build the database (DIGAD)
  • Phase 2: Transitioning the operation of the animal evaluation models (AE Transition)
  • Phase 3 and 4: Develop systems which facilitate certified herd testing providers submitting data directly to DIGAD. Design and implement a solution for breed societies.

Background of DIGAD

In 2008, DairyNZ established a committee headed by Professor Robert Anderson, to undertake a comprehensive review of the New Zealand dairy industry’s animal database.

The Committee sought and considered submissions from a range of organisations and individuals, and released a range of recommendations in a report titled the New Zealand Dairy Herd Improvement Database Review.

Two recommendations in this report were to transfer the Core Database and the animal evaluation function from LIC to an industry good body.

In August 2013, DairyNZ and LIC signed a formal agreement setting out the terms of the transfer of the Core Database and the licensing of the Animal Evaluation Intellectual Property to enable DairyNZ to operate and develop the New Zealand Animal Evaluation system.

What data does DIGAD contain?

DIGAD contains both core and non-core data, and there are separate regulations or conditions which control the use and distribution of each data set.

The core data comprises of 46 fields of raw data prescribed in the dairy industry (Herd Testing and New Zealand Dairy Core Database) Amendment Regulations 2014. The data is generated through herd recording (calvings/matings etc.) and herd measurement (herd testing, herd weighing). Data is initially collected by herd recording providers, who then pass it on to the DIGAD. There are regulations which restrict the use of core data, click here for further details set out in the regulations 2014.

Non-core data is also supplied by herd recording providers and includes information about body condition score, and traits other than production (such as udder support and cow temperament) which are collected and assessed by Participating Breed Society inspectors. The distribution of this data is governed through an agreement with the supplier and there are conditions around data use. Anyone requiring access to this data should discuss their requirements with the DIGAD Administrator.

The primary use of core and non-core data is to calculate the Breeding Worth of animals through the animal evaluation function. This function is currently performed by LIC on behalf of DairyNZ.

Core data is available through DairyNZ for industry good purposes, and access is granted through the core data access panel.

Confidentiality

DairyNZ as the custodian of the core database is governed by the Dairy Industry (Herd Testing and New Zealand Dairy Core Database) Regulations 2001.

Regulation 25 (Confidentiality) requires DairyNZ to keep confidential:

  • Information contained in an application to the Panel in relation to the supply of data in the core database
  • The fact that an application has been made.
  • The fact that any data in the core database has been made available as a result of an application.

Requests and subsequent data access is confidential. Details of the applicant, the intended use of data and the scope of data provided will not be disclosed outside DairyNZ or the access panel.

Access Data

Access to data held in the DIGAD can be formally requested through DairyNZ.

The governance process for accessing data ensures industry good data is protected from misuse and inappropriate distribution. All requests and data provisioning (including the intended use) will be tracked and monitored.

Requests and subsequent data access is confidential. Details of the applicant, the intended use of data and the scope of data provided will not be disclosed outside DairyNZ or the Access Panel.

How to request data

1. Complete the form below: The database administrator will discuss the following:

  1. What data fields are required and the scope of data required e.g. current season, last five years, production data, or summarised data.
  2. Intended use of the data.
  3. Data requirements from other sources, e.g. Some required data fields may not be held in DIGAD but could be available directly from Herd Recorders (LIC or CRV).

Supplying data to DIGAD

Herd test standard key points

Herd testing is available to all dairy farmers, providing the herd test standard can be met.

Key points covered by the Standard released in July 2015:

  1. Equipment used for herd testing must be approved by ICAR - International Committee for Animal Recording or historically approved via the dairy industry regulations(Herd Testing and New Zealand Dairy Core Database).
  2. Only data from a Certified Herd Tester enters DIGAD for use for research or animal evaluation purposes.
  3. Milk volume and milk component testing e.g. fat and protein percentages and somatic cell counts must be undertaken by an approved Certified Herd Tester. Note: There are currently two certified herd testers in NZ - LIC and CRV Ambreed.
  4. The protocols for herd testing and agreed formats for submitting data are specified in the Standard and all certified herd testers must follow these when herd testing and submitting data to DIGAD.
  5. A certified herd tester can use both traditional milk meters and permanently installed measurement equipment that meets accuracy requirements specified in the Standard.
  6. Milk component testing can be integrated with volume data collected by permanently installed measurement equipment.
  7. A range of herd testing options are available to suit different farming systems include once a day milking, 16 hourly milking, AM only, PM only, AM/PM and distributed milking systems.

To find out how herd testing can be carried out in your herd, please contact your preferred certified herd tester.

Contemporary groups for the animal evaluation system

A contemporary group is a group of animals within a herd who are the same age, and who calved in the same season (i.e. Spring calving).

All lactating cows in a contemporary group must be tested on the same day, with the exception of cows that are not fit for testing (sick/injured). More info available.
