Lamb cost of production: Finishing lambs

We present costing and performance insights for finishing lambs only, using Farmbench data.

What does the 2022/23 season tell us?

Income levels:

Despite small total income rises seen from the 2022/23 season sales (lambing in 2023) for the middle 50%, we saw total income fall for the top and bottom 25% Farmbench performers.

Costs:

On the cost side, Farmbench users saw higher total feed and forage costs for the middle 50% − contributing to a rise in total variable costs both for breeding ewes and finishing lambs. Interestingly, the top 25% performers kept feed and forage costs for 2022/23 lower than the middle 50% − this was the key factor in net margin differential for breeding ewes and finishing lambs. Though these top 25% enterprises generally had more forage area allocated in 2022/23 to the enterprise and minimised bought in feed.
Overhead costs too saw a large rise on the year for the middle 50% of Farmbench users (includes depreciation), contributed to in a large part by total labour, machinery and equipment, as well as property and energy.

Overall:

In 2022/23, total cost of production saw significant rises on the year for the middle 50% performers for both breeding ewes and finishing lambs. Though the picture was more mixed for breeding ewes, for finishing lambs Farmbench users saw rises in total cost of production across the board – from the top 25% all the way to bottom 25% performers.
Altogether we saw full economic net margin lower for breeding ewes across the board for 2022/23, with the middle 50% pushed into negative numbers (per ewe put to the ram). For finishing lambs, the full economic net margin was pushed into negative numbers across the board (per kg liveweight).

Characteristics of top and bottom performing beef and sheep farms

Our study uses a statistical examination of the Farm Business Survey and a case study analysis to identify the key actions of top performers. The study also offers a list of considerations for ways in which beef and sheep farm businesses can improve.

Two years of data about the costs of production and net margins are shown for the three Farmbench groups. The figures are per liveweight kg of output.

Understanding the data

Farmbench is an online benchmarking tool that allows you to compare your farm to similar businesses, facilitated by AHDB and our Farmbench managers.

The latest production year insights have been pulled from the tool and displayed below.

‘Production year’ means a 12-month period which covers all financial and physical activity relating to the production of the annual crop (plant or animal) from an enterprise. For example, the 2022/23 production year is associated to 2023 lambing, and calving for autumn 2022 and spring 2023.

For 2022/23 insights, the tool gathered data from a total of 86 farms across England, similar to 81 in the 2021/22 season.

This 2022/23 total included 57 suckler herd, 41 finishing beef and 35 store beef enterprises, and 61 breeding flock and 34 finishing lamb enterprises. Lambs finished before tupping are included within the breeding flock, any retained and sold from tupping onwards are included within the finishing lamb enterprise.

All the data has been averaged into three benchmark groups and ranked by full economic net profit margin: top 25%, middle 50% and bottom 25%.
