A new “mix and match” calculator that considers the cost and margins of introducing a beef herd into an arable rotation has been developed by the AHDB.

For growers who are considering making the move and integrating cattle on farm, the tool aims to clarify their business idea by estimating the potential cattle margin.

The cost calculator takes users through two easy-to-follow steps and considers the various costs associated with setting up livestock on farm, from establishing grass leys and rearing animals to fencing infrastructure.

Cost calculations

The first step involves inputting the required quantity of the inputs/products in to their dedicated boxes and selecting options from the drop-down menu for the following categories:

• Boundary fencing
• Internal fencing
• Water and electricity
• Water troughs, pipes and fittings
• Ley establishment
• Type of ley
• Tillage system
• Grassland management
• Silage or hay crop
• Cattle rearing costs
• Labour input
• Concentrate feed.

All users need to do is provide the estimated quantities that they will need and the calculator will provide an indicative cost.

For each cost area, the calculator allows you to select from different sub-divided options.

For example, fencing is divided into temporary, semi-permanent and permanent.

Step two involves entering an approximate lifetime expectancy for the length of the grass ley and fencing, as well as an estimated number of days of grazing throughout the season.

The calculator then finalises the estimated set-up costs, and total rearing costs to generate a margin that will help growers identify whether the venture is worthwhile.

It is worth noting that figures provided should only be used as a guide.

The calculator does not currently include any residual benefits from the inclusion of grass leys in the rotation, such as changes in soil organic matter or weed control.
