UK Farm Animal Genetic Resources (FAnGR) breed inventory results 2023 statistics release
Updated 15 October 2024
The Farm Animal Genetic Resources inventory has received its annual updates based on data provided by the breed societies. This includes inventory data for 2023, estimated breeding female population figures for 2024 and in some cases revisions for earlier years.
The full dataset is very detailed and presented as a number of time series tables in a spreadsheet on the FAnGR Annual Statistics page. It presents both the data characteristics collected in the inventory and additional estimates of the populations for breeding females and the effective population for each breed.
This Statistics Notice provides a summary of the data on the estimated population of breeding females for cattle, sheep, pigs, and goats.

Section 1 - UK Farm Animal Genetic Resources (FAnGR) Inventory
1.1 Background
The UK has one of the richest native Farm Animal Genetic Resources (FAnGR) populations in the world and the importance of FAnGR has been recognised at both international and UK levels. Because of this, a commitment was made under national and global biodiversity strategies to establish an annual inventory to show how breed populations are changing over time.
1.2 Data characteristics
Certain data characteristics are collected directly from the annual inventory survey. Further key population estimates can then be derived from these.
Characteristic | Type |
---|---|
Female registrations | Inventory |
Male registrations | Inventory |
Dams | Inventory |
Sires | Inventory |
Breeding herds | Inventory |
Female breeding population | Population Estimate |
Effective population | Population Estimate |
Details of how the population estimates are calculated are provided in Section 6. Note that the female breeding population estimate is calculated using the 3-year average of the number of female registrations and as such, the 2024 estimate is calculated using inventory data for 2021, 2022 and 2023.
The breeding female population figures for pigs except for the British Lop and Kune Kune are actual census figures for live animals rather than estimates based on registrations. For this reason, the population census figures appear in the year in which the data was collected as they represent the actual live population at that point in time.
All data including inventory data, estimates and breed status are published separately from this Statistics Notice on the same collection page :- UK farm animal genetic resources (FAnGR): breed inventory results
The dataset provides a timeseries from 2000 to 2023/ 2024 for cattle, sheep, pig, goat, horse and camelid breeds. A machine-readable dataset is also available at the same collection page.
1.3 Breed status
Breeds can have NBAR (Native breed at risk) or BAR (Breed at risk) status. This status is determined by the number of registered breeding females and breeds are included on the NBAR and BAR when their populations drop below specified thresholds. These thresholds are included in Section 6.
Section 2 – Key trends in breeding female population estimates
2.1 Introduction
This section focuses on the derived measure of the estimated breeding female population for native breeds. Details of how this is estimate is calculated, and a definition of native breeds can be found in Section 6. No horse data are available as a multiplier to estimate the female breeding size is currently under development.
Table 2.1 shows the total number of breeds for each species broken down by breed status included in the inventory. The total number of native breeds in the inventory are higher than those found in the Section 2 due to missing data for a number of breeds.
Table 2.1 - Total number of breeds by breed status for each species
Number of breeds | Cattle | Sheep | Pigs | Goats |
---|---|---|---|---|
Total | 53 | 87 | 16 | 14 |
Native | 30 | 61 | 11 | 5 |
NBAR | 24 | 48 | 11 | 5 |
BAR | 14 | 29 | 11 | 5 |
2.1a Data presentation
The data presented in section 2.2 – 2.6 show the estimated female population sizes for the following target years: 2020 and 2024 for cattle, sheep and goats, and 2019 and 2023 for pigs. In sections 2.3 – 2.6, the data are presented in a barchart and table displaying the percentage change in population between the target years for native breeds showing an increase or decrease of more than 5% (for more information on the methodology, please see Section 6). A threshold change of 5% within a 5-year timeframe was chosen to facilitate the early identification of breeds with declining populations as breeds of concern.
Where there are incomplete data in the target years, the breeds have been excluded from the analysis. If data are supplied subsequent to this publication, published results will be updated as early as possible.
2.2 Key Trends - Summary of results for Cattle, Sheep, Pigs and Goats
Based on the estimated number of breeding females, the change in population size for native breeds between 2020 and 2024 is shown in table 2.2
Table 2.2 Change in estimated breeding female population between 2020 and 2024 by number of native breeds
Number of breeds | Cattle | Goats | Sheep | Pigs |
---|---|---|---|---|
Large increase (above 25%) | 5 | 2 | 7 | 0 |
Small increase (above or equal to 5%) | 7 | 0 | 12 | 0 |
No change (between 5% and -5%) | 6 | 1 | 10 | 2 |
Small decrease (below or equal to -5%) | 10 | 1 | 14 | 6 |
Large decrease (below -25%) | 2 | 0 | 7 | 3 |
Total | 30 | 4 | 50 | 11 |
Notes:
- Increase or decrease is by more than 5% otherwise it is classed as no change.
- Pig data compares figures for 2019 and 2023 as census data is available.
- Only includes native breeds with data for both 2020 and 2024 (2019 and 2023 in the case of pig breeds).
The majority of native cattle and sheeps breeds are showing a small increase or small decrease in population size between 2020 and 2024. As in previous years, the native pig breeds show an overall decreasing trend in population size while the population size of most native goat breeds are increasing.
Annual trends in native farm animal populations should be understood in the context of changes in the general UK livestock populations. Please see the livestock population statistics collection page for data on livestock populations in England and UK.

Section 3 – Notes relating to specific species and breeds
These breed notes provide specific context for data in the inventory tables and Section 2 of this statistics notice.
Breed | Notes |
---|---|
Cattle | |
Merged Breeds | A decision has been made by Defra to merge original populations with their commercial populations for inventory recording. This decision was made to mitigate circumstances in which the original populations were recorded twice, in their own figures, and in the figures provided by commercial populations, which would give an inaccurate view of true numbers. |
Aberdeen Angus | This includes Aberdeen Angus and Aberdeen Angus (original population) |
British Friesian | This includes British Friesian and British Friesian (original population) |
Dairy Shorthorn | Excludes Northern Dairy Shorthorns as these are reported separately. Includes the Dairy Shorthorn (original population). |
Hereford | This includes Hereford Traditional/Original. |
Sheep | |
Badger Face Welsh | From 2020 this breed is now recognised as two separately recorded registered breeds: Torddu Badger Face and Torwen Badger Face. |
Composite Breeds | Since 2021, we have included several composite sheep breeds in the inventory (namely the Aberblack, Aberdale, Aberfield, Abermax, Abertek, Highlander and Primera in addition to the previously recorded British Milksheep, Cambridge and Exlana). Sheep populations are dynamic, with new composite breeds of sheep being developed from existing genetic resources all the time to create maternal and terminal sire composite breeding lines. |
Hill breeds with incomplete data | The following extensively managed sheep breeds are recognised as important genetic resources. However at present we have no means of recording actual numbers as extensive management systems make pedigree recording difficult. |
Beulah Speckled Face | Incomplete data since 2017. |
Black Welsh Mountain | Incomplete data. |
Brecknock Hill Cheviot | No data available. |
Herdwick | Male registration data and number of active flocks data available. Females not individually registered. |
North Country Cheviot | Male registration data available. Females not individually registered. |
Rough Fell | Male registration data and number of active flocks data available. Females not individually registered. |
Scottish Blackface | No data available. |
Shetland Island | No data available since 2014. |
South Country Cheviot | Male registration data and number of active flocks data available. Females not individually registered. |
South Wales Mountain (Nelson type) | No data available. |
Swaledale | Male registration data available. Female population data is census data. |
Welsh Hill Speckled Face | Number of active flocks data available. Females not individually registered. |
Pigs | |
All breeds except Kune Kune and British Lop | The breeding female populations of all the pig breeds in the inventory except for the British Lop and Kune Kune are actual census figures for live animals rather than estimates based on registrations. For this reason the population census figures appear in year in which the data was collected as they represent the actual live population at that point in time. |
Commercial Breeds | The UK’s commercial breeding base of some 340K sows is supported by breeding companies operating closed breeding programmes licenced by Defra. These companies represent 85% of the genetic resources for pig production in the UK. They are also linked into international breeding programmes and are a source of genetics for breeding programmes around the world. For reasons of commercial confidentiality, details of their populations are not published however information on their breeding lines and programmes can be found on the UKGLE website: Recognised breeding operations for hybrid pigs |
Goats | |
Cheviot (Feral) | The data received for Cheviot goats has not been published due to new methodology. The UKGLE committee will be reviewing the data and when a decision has been made a revision of the inventory including the Cheviot goats will be published. |
Yorkshire Dairy Goats | The number of female registrations relates to the number of females that have been born and added to the herd register. |
Horses | |
Caspian | Data is incomplete. Work is being done to improve coverage in future to give a truer picture of the breed statistics. |
Irish Draught | Only UK born, pure-bred pedigree registration types have been included (i.e. at least 3 or 4 generations of pure-bred pedigree). No grading up or cross-bred animals are included in these figures. |
Section 4 - Removed Breeds
Breeds for which there is a lack of data provision for the last 3 years or more are removed from the main inventory results and instead presented here. If they are able to provide data again, the breed can be reinstated in the main inventory and we would like to encourage breed societies to contact the UKGLE secretariat (ukglesecretariat@defra.gov.uk) if there is anything we can do to help them provide this information.

Section 6 – About these statistics
6.1 Background
The UK has one of the richest native Farm Animal Genetic Resources (FAnGR) populations in the world and the importance of FAnGR has been recognised at both international and UK levels.
Because of this, a commitment was made under national and global biodiversity strategies to establish an annual inventory to show how breed populations are changing over time. The inventory was set up by Defra in 2013 to deliver that commitment and the inventory is steadily increasing in scope and coverage each year as it becomes established. Once the trends become apparent from the inventory, it enables decisions to be made to safeguard UK livestock biodiversity and to help future-proof UK farming.
The results build on the findings from the 2012 “UK Country Report on Farm Animal Genetic Resources (FAnGR)” and are a collaborative effort between the national UK Genetics for Livestock and Equines Committee (UKGLE), Defra and the Devolved Administrations, who work together to support the conservation and sustainable use of UK FAnGR. The inventory complements the committee’s other monitoring efforts and the work of the Rare Breeds Survival Trust on conservation and protection of UK rare and native breeds of farm animals.
6.2 Data Sources
All the annual data is reported through either Grassroots Systems Ltd., the British Pig Association or the Rare Breeds Survival Trust. Coverage has been steadily increasing since the annual inventory was first developed in 2013. The response rate for the 2023 inventory was 93% (210 breeds). Breed societies have given their permission for these companies to supply the data every year for this exercise. Any breed-specific exceptions to this coverage are detailed in the ‘Definitions & Breed notes’ section.
The pig data on numbers of pedigree breeding sows (with the exception of the British Lop and KuneKune) are sourced from the Bloodline Census, an annual exercise carried out by the British Pig Association (results are available on the British Pigs website). This Census also collects data on the number of members keeping registered pigs.
Data for all other breeds are collected annually via a survey. Questionnaires are emailed and non-respondents are contacted several times to encourage response. Priority is given to gathering comprehensive data from native breeds. It is made clear to participating breed societies in advance that all data supplied will be published (as it is all collected at the aggregate level). Therefore, there are no confidentiality issues around the data. Some breed societies already publish this information in their flock/herd books.
6.3 Data characteristics
6.3.1 Inventory data
The following data characteristics are collected from the inventory survey for all species.
Characteristic | Definition |
---|---|
Female registrations | Only includes fully pure-bred, pedigree registered, UK born animals which were registered (not born) in the year. |
Male registrations | Only includes fully pure-bred, pedigree registered, UK born animals which were registered (not born) in the year. |
Dams | Pedigree dams of fully registered animals in the year. Excludes dams which had offspring which were not registered. |
Sires | Pedigree sires of fully registered animals in the year. Excludes sires which had offspring which were not registered. |
Breeding Herds | Number of active pedigree herds/flocks which registered pedigree offspring in the specific year. |
6.3.2 Population estimates
The following data characteristics are population estimates which are calculated using the inventory data.
Breeding female population
A key data characteristic is the size of the pedigree breeding female population. The actual number of these animals is not always directly available from breed societies as the databases are not always up to date. For Cattle, Sheep, Goats and two Pig breeds (British Lop and Kune Kune) estimates are made of this key measure by multiplying the average number of pedigree female registrations over the previous three complete years by multipliers defined for each species (see table below). The multiplier is calculated using historic data on the ratio of the number of adult females in a breed to the number of female registrations in a year.
The female population figures for pig breeds other than the British Lop and Kune Kune are actual census figures for live animals rather than estimates based on registrations. For this reason, the population census figures appear in the year in which the data was collected as they represent the actual live population at that point in time.
Currently, no data are available for horse female population sizes, however a multiplier is under development.
Species | Breeds | Multiplier |
---|---|---|
Cattle | All | 3.52 |
Sheep | All | 2.41 |
Goats | All | 5.16 |
Pigs | KuneKune & British Lop | 2.70 |
Effective population
The effective population size indicates the genetic diversity within the breed, by accounting for the total number of animals in a population and the relative numbers of male and female parents (sires and dams). A low effective population size signifies a greater likelihood of inbreeding and a higher risk of loss of genetic diversity. An effective population of 50 is set as a threshold for concern by the United Nations Food and Agriculture Organization. For further details see the JNCC bio-diversity indicator Technical background document.
The effective population size for each breed in the inventory is calculated using Sewell Wright’s formula:
Effective population = 4 x (No. sires x No. dams)/ (No. sires + No. dams)
6.4 Breed Status
Native Breeds
For a breed to be considered native, the breed should satisfy all of the following criteria.
- The breed satisfies the criteria for inclusion in the UK National Breed Inventory.
- Breed history documents the breed origin within the UK (including from an amalgamation of native breeds) and the UK has formed the primary environment for the development of the breed.
- Breed history documents its presence in the UK in its current adapted form for a qualifying period of at least 40 years or 6 generations whichever is the longer period of time.
- Not more than 20% of the genetic contributions come from animals born outside the UK (other than those imported for an approved conservation project) in any one generation for the last 40 years plus 6 generations.
NBAR and BAR Breeds
Breeds can also have NBAR (Native breed at risk) or BAR (Breed at risk) status. This status is determined by the number of registered breeding females and breeds are included on the NBAR and BAR when their populations drop below specified thresholds. The thresholds for each species are as follows:
Species | NBAR Thresholds | BAR Thresholds |
---|---|---|
Cattle | < 7500 | < 3000 |
Equines | < 5000 | < 3000 |
Goats | < 10000 | < 3000 |
Pigs | < 15000 | < 1500 |
Sheep | < 10000 | < 3000 |
Poultry | < 25000 | < 1000 |
