24 June 2021 UK Farm Animal Genetic Resources (FAnGR) Inventory 2020 The Farm Animal Genetic Resources inventory has received its annual updates based on data provided by the breed societies. This includes inventory data for 2020, estimated breeding female population figures for 2021 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 webpage. 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. Key results Based on the estimated number of breeding females, the population of native breeds for each species showed the following changes between 2017 and 2021: Number of breeds Cattle Sheep Pigs Goats Increase 9 15 0 5 No change 11 17 3 0 Decrease 9 13 8 0 Total 29 45 11 5 Notes: 1. Increase or decrease is by more than 10% otherwise it is classed as no change 2. Only includes breeds with data for both 2017 and 2021 This shows a mixed picture for cattle and sheep with more than half the breeds showing either an increase or a decrease. Pigs show an overall trend of falling populations whilst goats are showing an overall increasing trend.

Acknowledgements The FAnGR committee would like to thank all those breed societies already taking part and to Grassroots Systems Ltd., the Rare Breeds Survival Trust and the British Pig Association for their high level of support and input into this project. The FAnGR team would also be happy to hear your feedback on this publication and how it can be improved for future years. The next scheduled release is due to be published in the Spring of 2022 which will include data for 2021. 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. 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 estimate parameters are calculated are provided in Section 6 About these statistics. Note that because the female breeding population estimate is based on the 3-year average of the number of female registrations and a multiplier, an estimate can be calculated for 2021 based on inventory data for 2018, 2019 and 2020. All data including inventory data, estimated data and breed status are published separately from this Statistics Notice on the same collection page here:- UK farm animal genetic resources (FAnGR): breed inventory results - GOV.UK (www.gov.uk) These are presented in a spreadsheet that provides a time series from 2000 to 2020/21 for all breeds for each species. 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 About these statistics. Section 2 – Key trends in breeding female population estimates for native breeds of cattle, sheep, pigs and goats 2.1 Introduction This section focusses on the derived measure of the estimated breeding female population for native breeds. Details of how this is calculated are in Section 6 About these statistics. No horse data is available as no multipliers have been determined from which to estimate the breeding female population. Table 2.1 Total number of breeds by category for each species Number of breeds Cattle Sheep Pigs Goats Native 31 62 11 6 NBAR 24 49 11 6 BAR 17 29 11 6 Total 53 81 16 15 The data presented shows the population sizes for 2017 and 2021. For each species the data are presented in line charts. These are split into two separate charts to make the trends easier to pick out. The first chart shows all breeds that have shown an increase of more than 10% and the second shows all breeds that have shown a decrease of more than 10%. The charts use a logarithmic scale with base 10. This allows the results for all breeds to be presented clearly together despite the wide variation in population sizes. Using the logarithmic scale, a 50% change in a population of 10,000 will appear as large as a 50% change in a population of 100. Using a conventional scale, the change in the smaller population would be so small as to be impossible to detect on the chart. A summary data table also presents the full set of data for all native breeds of that species, showing the percentage change between 2017 and 2021. 2.2 Summary of results for all species Based on the estimated number of breeding females, the change in population size for native breeds between 2017 and 2021 is shown in table 2.2 Table 2.2 – Change in population between 2017 and 2021 by number of breeds Number of breeds Cattle Sheep Pigs Goats Increase 9 15 0 5 No change 11 17 3 0 Decrease 9 13 8 0 Total 29 45 11 5 Notes: 1. Only includes breeds with data for both 2017 and 2021 so totals are lower than in table 2.1 2. Pig data compares figures for 2016 and 2020 as census data is available This shows a mixed picture for cattle and sheep with some breeds showing an increase and others a decrease. Pigs show an overall trend of falling populations whilst goats are showing an overall increasing trend. 2.3 Cattle Results Chart 2.3a Cattle breeds increasing by more than 10% between 2017 and 2021 (N=9) Chart 2.3b Cattle breeds decreasing by more than 10% between 2017 and 2021 (N=9) Table 2.3 Native cattle breeds and % change (in descending order of change) Published Cattle Breed Name 2017 2021 % Change Vaynol 8 16 +100% Whitebred Shorthorn 209 381 +82% Northern Dairy Shorthorn 74 115 +55% Luing 5,478 8,044 +47% Belted Galloway 3,214 4,145 +29% Beef Shorthorn 10,210 11,818 +16% British Friesian 10,635 11,990 +13% Hereford 17,361 19,327 +11% White Galloway 217 239 +10% Shetland 636 676 +6% Galloway 2,942 3,085 +5% White Park 726 744 +2% Devon (Red Ruby Devon) 7,499 7,669 +2% Aberdeen-Angus 34,795 35,566 +2% Jersey 23,825 23,570 -1% Guernsey 2,732 2,682 -2% British White 1,140 1,117 -2% Gloucester 473 460 -3% Red Poll 2,795 2,702 -3% Highland 3,451 3,161 -8% Irish Moiled 659 587 -11% Dexter 6,747 5,802 -14% English
