Tools to calculate 24 hour yields from AM/PM milkings
The following tools, developed as Excel files, can be used to calculate 24-hour yields using methods that are described in Section 2 of the ICAR guidelines. The yields can be calculated for a few animals or to check if you have implemented these methods well in your organisation.
- Method of Delorenzo and Wiggans (2 milkings per day)
- Method of Delorenzo and Wiggans (3 milkings per day)
- Method of Liu (The factors of the Liu-method that are used in the Excel file are re-estimated by VIT in 2019. These factors slightly deviate from the ones used in the ICAR Guidelines)

ICAR Dairy Cattle Milk Recording Working Group Membership
It may be seem that this WG will cover all aspects of dairy cattle recording, from the systems used on farm now and in the future, to lactation calculations and to ensure that the ICAR membership have the most appropriate Guidelines to ensure best practice for their respective users.
There should be no part of dairy cattle milk recording which is not covered by this WG, so the skills required by its members will vary from providers of on-farm recording, users of information provided, those who require phenotypic data as well as those how use information for genetic evaluations (although most of this aspect will be covered by the ICAR subcommittee Interbull).
The Working Group will be responsible for:
- 1. Ensuring that the published ICAR Guidelines are relevant in respect of dairy cattle milk recording.
- Regularly collating and tabulating the recording methods used by ICAR members.
- Based upon data and information gathered:
- a. Make such recommendations, based upon sound scientific and economic principles, to improve the relevant ICAR Guidelines, and
- b.To provide analysis to the membership on the different methods practiced
- To monitor relevant developments in non-ICAR member activities and businesses and, where appropriate, report accordingly.
- To recommend changes to Guidelines relating to areas such as lactation calculation methods, where new scientific or economic knowledge will bring about a measurable benefit to the members.
- To liaise with the other ICAR subcommittees and working groups.
