HerdPlus Beef Output Report Now Available

The latest HerdPlus Beef Output Reports have been generated and are now available online. The HerdPlus team is currently in the process of posting reports to customers. This report assesses the productivity of beef herds based on their liveweight output. The report is broken down into the following

Section 1. Summary Data

Section 1 outlines the herds data for three key figures; Total Beef Output, Total Livestock Units (LU) and Total Hectares. These figures then form the basis of the Key Performance Indicators in Section 2.

A. Total Beef Output (Kgs)

This details the total beef output of the herd in Kgs liveweight.

B. Total Livestock Units (LU)

This details the average livestock units (LU) in the herd in the chosen year.

  • Animals 0-6 months = 0.2 LU.
  • 6-12 months = 0.4 LU.
  • 1-2 yrs = 0.7 LU.
  • 2+ yrs (including stock bulls) = 1 LU.
  • Suckler Cows = 0.9 LU

C. Total Hectares

This details the land available to the herd’s cattle enterprise. This figure comes from the Beef Profit monitor or alternatively from the Supplementary Details section of the Herd Info screen. These have been entered by a farmer/advisor prior to the reports being generated. If hectares are missing then report will be generated without this piece of information.

Section 2. Key Performance Indicators (KPI’s)

This section uses the information provided in Section 1 to display the following Key Performance Indicators (KPI’s) for the herd: Beef Output per Livestock Unit, Beef Output per Hectare and Stocking Rate per Hectare. This section also displays the National Average for the same KPI.

A. Beef Output per Livestock Unit (LU)

This is equal to the Total Beef Output figure divided by the Total Livestock units

B. Beef Output per Hectare

This is equal to the Total Beef Output figure divided by the Total Hectares.

C. Stocking Rate per Hectare

This is equal to the Total Livestock Units divided by the Total Hectares.
PLEASE NOTE: Where the Total Hectare figure is missing for a herd, KPI’s A. Beef Output per Livestock Unit and B. Beef Output per Hectare will be blank.

KPI Benchmark Graph

Alongside each of the KPI’s listed above, a bar graph is displayed which shows the hers own performance benchmarked against the national average, top and bottom 1/3 of herds nationally. See below:



At the bottom of Page 1 is a table which gives target Beef Output per LU for various beef systems as outlined by Teagasc. The figures in this table are fixed and so will be the same for every herd. This table is as follows:


A beef system which keeps animals in the herd for a longer period (e.g. Calf to Beef vs. Store to Beef) should expect a greater difference between the weights of animals entering the herd and animals leaving and therefore are given a higher target Beef Output per LU.

3. Sales

This section gives a breakdown of all of the animals sold from the herd in the selected year by age and sex. This section is similar to the sales and purchases tab of the profit monitor. All weights displayed are liveweights regardless of whether the animal was sold alive or sold to the factory for slaughter. These liveweights will either be:

  • Mart weights.
    • Unlike with Genetic Evaluations, where an animal must be sold as a single lot for the weight to be used, the total weight of a group of animals sold together can be used here as the total weight of the group will be the same regardless of the variation of individual weights within the group.
  • Farmer recorded weights.
    • Herd-owners can record the sales weight of the animal via the Beef Profit Monitor. Liveweights recorded via the Record Liveweight screen can also be counted if the date of weighing is close enough to the date of sale.
  • Liveweights estimated from carcass weights.
    • Liveweights are estimated from carcass weights assuming a standard Kill-out% based on breed
  • Liveweights estimated by age and breed.
    • This will only be the case where no sale weight or slaughter data exists in the database.

4. Purchases

This section gives a breakdown of all of the animals purchased into the herd in the selected year by age and sex. The weights of these animals come from the same sources as the Sales section outlined above.

Inventory Change

Inventory change is the difference in stock numbers in a herd, from the start of the year (Opening Stock, 1st Jan) to the end of the year (Closing Stock, 31st Dec). The stock numbers used come are the same as those found in the Beef Profit Monitor or in the Stock reconciliation report. This is displayed in terms of liveweight as follows:

A. Opening Stock

This is the stock numbers on January 1st of the selected year multiplied the average weight of the different animals types in that group (e.g. Suckler Cows, 0-6 month males etc.).

B. Closing Stock

This is the stock numbers on December 31st of the selected year multiplied the average weight of the different animals types in that group (e.g. Suckler Cows, 0-6 month males etc.)

C. Inventory Change

This is equal to the Closing Stock (Kg Liveweight) – Opening Stock (Kg Liveweight)


A herd had an opening stock, on 1st Jan, of 30, 1-2 year old males and a closing stock, on 31st Dec, of 35, 1-2 year old males. The inventory change for 1-2 year old males would, therefore, be +5 as there were 5 more animals in the 1-2 year male category, in the herd, at the end of the year. To get the inventory change in Kgs of liveweight, you simply multiply the number of animals by the average liveweight for animals in that category. See calculation below:


If the herd had less animals at the end of the year, then the inventory change would be a minus figure.
PLEASE NOTE: Unlike in the Sales and Purchases sections, actual Liveweights of individual animals are not used to calculate inventory change. A standard average Liveweight for each animal type is assumed e.g. each Suckler Cow = 600Kg

Why is Inventory Change included?

The Beef Output report aims to measure the amount of Beef Liveweight produced on the farm in the given year through the growth of the beef stock on the farm. The Inventory Change figure is necessary part of the calculation of Beef Output to prevent the figure being artificially raised or lowered by expansion or contraction of overall herd size.

For example, if a herd sold a larger than usual number of Suckler Cows in a given year, effectively reducing the overall size of the herd, then the Kg Liveweight of all these Suckler Cows would cause the Kgs Liveweight Sold for the year to increase. The Liveweight of these cows is unlikely to have changed significantly in the same period and ,therefore, their Liveweight cannot be considered as Beef Output. However if the herd ends the year with less Suckler Cows than it started with, then the resulting inventory change for Suckler Cows will be a minus figure thus negating the extra Kg Liveweight in Sales section.
