2.2 Average weekly number of home killed livestock slaughtered

Table 2.2 shows the average weekly slaughter figures for the last three months and the previous year’s current month for comparison. The monthly slaughter figures in section one are affected by the number of days in the survey period. To get a clearer measure of trends weekly averages are calculated using the number of livestock slaughtered and the number of days in each period. Longer term trends can be seen in Figures 2.1, 2.2 and 2.3, following this table.

5. About these statistics

5.1 Methodology

Following a quality assurance exercise, livestock numbers from April 2023 will be obtained from Food Standards Agency (FSA) administrative data. The FSA data provides complete monthly coverage of slaughterhouse throughput in England and Wales.

Defra runs monthly slaughterhouse surveys that collects information on livestock slaughter numbers and weight of meat produced by category. These data are used to apportion FSA data into livestock categories and for quality assurance purposes. The survey goes to all major slaughterhouses and survey response is typically around 90%.

Similar surveys are run by RESAS in Scotland and by DAERA in Northern Ireland. Scottish statistics on livestock slaughterings are available in [the Economic Report on Scottish Agriculture at the Economic Report on Scottish Agriculture webpage from Scottish government (Tables A5 and A6). This website also contains contact details and more information. Northern Ireland results are available at the Northern Ireland cattle sheep slaughterings webpage and Northern Ireland pig slaughterings webpage.

Information on the weight of meat produced from a sample of animals weighed at slaughterhouses is obtained from survey respondents. From the information provided average dressed carcase weights for each animal type are primarily calculated by adding up the total weight of the meat produced and dividing by the number of animals weighed. Cold dressed carcase weights are recorded.

The volume of meat production is estimated from the number of all livestock slaughtered and average dressed carcase weight information collected. This total ‘Home killed’ production includes livestock imported into the United Kingdom for slaughter.

With effect from February 2016 the statistics published in this notice are based on calendar rather than statistical months. This change simplifies our survey processes and brings our slaughter survey in line with our milk surveys which are already run on a calendar month basis; it also removes the need for the 53 week year (which would have to be 2016). Since the end of weekly slaughter survey several years ago, there is no legislative requirement for weekly data, so since then we have derived the average weekly throughput from the monthly survey data.

The January 2016 data will include the last week of December 2015 and therefore be classed as a 5-week month. From 1st February 2016 onwards the statistics are based on calendar months.

We have carried out a review of the methodology for calculating the dressed carcase weights in order to align with UK specifications. Some slaughterhouses provide Cattle Dressed Carcase Weights (DCW) including Kidney Knob and Channel Fat (KKCF); some slaughterhouses provide pig weights at EC specification. From September 2019 cattle DCWs are calculated to UK specification which excludes KKCF; Pigs are dressed to UK specification.

To calculate the DCW of animals by category:

• If the slaughterhouse includes KKCF in the total weight, a deduction of 3.9% occurs. This aligns to the UK DCW specification.

• Link to beef carcase classification scheme webpage

• If pigs are dressed to EC specification then an increase of 1.6% to the DCW occurs to align with UK specification.
• Link to pig carcase grade scheme webpage

Some slaughterhouses specialise for niche markets. These slaughterhouses are treated separately so their DCW are not used to raise the data for those slaughterhouses who do not provide DCW data.

Data have been revised to January 2018 using the new methodology. If you have any questions or comments, please contact us at livestock.statistics@defra.gov.uk

5.2 Revisions

5.2.1a Revision – April 2023

From April 2023 we have revised our livestock numbers across all categories from January 2021 to March 2023. The updated figures have been included in the accompanying dataset.

This revision is due to an issue identified in our previous methodology for calculating slaughter numbers. Due to the method of processing the monthly figures, subsequent updates to the slaughter numbers from the Food Standards Agency were not captured and there was underestimation of slaughter numbers in some categories. We have revised the data from January 2021 to March 2023 to capture these updated figures. Further we have revised our livestock categories ratios based on previous year’s survey data for data accuracy purposes.

Due to the change in methodology comparisons with previous years will not be possible.

If you have any questions or comments, please contact us at livestock.statistics@defra.gov.uk

5.2.1b Revision – October 2023

From October 2023 we have revised our pig slaughter figures between January 2021 to September 2023. The updated figures have been included in the accompanying dataset.

This revision is due to the development of a new methodology for apportioning FSA pig slaughter numbers into the categories: clean pigs and, sows and boars. From October 2023 we stratified the pig abattoirs into 2 strata, one stratum for those abattoirs that have a large throughput of sows and boars and one for the rest and raise the data separately. This change was made as we feedback indicated that our survey was not representative for pigs, as we were surveying 100% of those abattoirs with a large throughput of sows and boars.

Due to the change in methodology comparisons with previous years will not be possible.

If you have any questions or comments, please contact us at livestock.statistics@defra.gov.uk

5.2.2 Revision Policy

Figures in this notice are provisional and subject to revision. We will provide information about any revisions we make to previously published information in this statistics notice and the associated datasets. Revisions could occur for various reasons, including:

• if we have not received survey data from respondents we make an estimate based on their previous returns. These estimates will be replaced with actual survey data when it is received.

• survey respondents occasionally supply amended figures for previous periods.

• FSA administrative data can be revised up to two months after production. We will include any revised data in the subsequent publication releases.

5.3 Data users

The livestock industry is a major user of the data, including divisions of the Agriculture and Horticulture Development Board (AHDB). AHDB Pork (formally known as BPEX, representing the English pig industry) and AHDB Beef and Lamb (formerly EBLEX, representing the English beef and sheep industry). Industry users rely heavily on the numbers of slaughterings and meat production to assess the current state of the industry and predict the available supplies of meat for the coming year. This, in turn, can affect meat prices and trade decisions on levels of imports and exports to maintain supply. Users have always been very keen for the slaughtering statistics to be produced as quickly as possible so that the data is still relevant. For this reason, we collect and publish these statistics to a very tight timetable, publishing within three weeks of the survey date. The “Market Intelligence” and “Market Outlook” Reports on the AHDB Beef and Lamb website refer consistently to our statistics at the AHDB Beef and lamb webpage The AHDB Pork site provides more in-depth analysis of pigmeat production statistics at the AHDB pigmeat production webpage.

6. Definitions

• Steers (or Bullocks): Castrated males over 1 year old, raised for beef.

• Heifers: Female animals that have not calved. Over 1 year old, raised for beef.

• Young bulls: Non-castrated young males, raised for beef, generally slaughtered around 13 months old.

• Prime cattle: All those raised specifically for beef production. Total of Steers + Heifers + Young Bulls.

• Breeding bulls: Older cull males, previously used for breeding

• Cows: Older cull females, previously used for breeding

• Calves: All bovine animals aged 1 year old or younger. Prior to May 2014, the definition was “animals weighing less than 165kg”.

7. Accredited official status

Accredited official statistics are called National Statistics in the Statistics and Registration Service Act 2007. An explanation can be found on the Office for Statistics Regulation website.

Our statistical practice is regulated by the Office for Statistics Regulation (OSR). OSR sets the standards of trustworthiness, quality and value in the Code of Practice for Statistics that all producers of official statistics should adhere to.

These accredited official statistics were independently reviewed by the Office for Statistics Regulation in 2014. They comply with the standards of trustworthiness, quality and value in the Code of Practice for Statistics and should be labelled ‘accredited official statistics’.

You are welcome to contact us directly with any comments about how we meet these standards (see contact details below). Alternatively, you can contact OSR by emailing regulation@statistics.gov.uk or via the OSR website.

Since the latest review by the Office for Statistics Regulation, we have continued to comply with the Code of Practice for Statistics, and have made the following improvements:

• In 2016 we changed the reporting of our livestock statistics to calendar months from statistical months in response to user feedback.

• In 2019 we carried out a review and changed the methodology for calculating dressed carcase weights in order to align with UK specifications.

• In 2023, after a quality assurance exercise, we changed the data source of our livestock slaughter numbers to Food Standards Agency (FSA) administrative data. The FSA data provides full monthly coverage of slaughterhouse throughput in England and Wales.

• In 2023, in response to user feedback, we changed our methodology for apportioning pig slaughter data into clean pigs and sows and boars categories.

8. Future publications

This notice will be updated at 09:30 on Thursday, 16 January 2025. Additional time series which include weekly slaughter averages, production and trade data can be found at the the UK government livestock statistics web page.
