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.

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.

Section 3 – Inventory Annex

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 in a separate

annex. 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 us if there is

anything we can do to help them provide this information.

Section 4 – Cryogenic Material

To help ensure the long-term survival of pedigree breeds, genetic material can be

kept in cryogenic storage. This process freezes both semen and embryos so that

they can be used in the future for breeding purposes. Due to technical difficulties, scientific limitation and costs, storage of embryos is less common than semen.

Cryogenic material is held as both a public asset and by organisations for

commercial purposes. We are primarily interested in the material stored as a public

asset.

Given the importance of cryogenic material for the long-term survival of pedigree

breeds we are building our capacity to collect and publish reliable estimates. Data

were collected this year for the first time on the numbers of donors and samples for

both semen and embryos. The data received to date is only partially complete, so

we are currently unable to publish reliable estimates. Further work will be done to

improve the data collection process and we intend to publish results at some point in the future.

Of the Breeds At Risk (BAR), over 80% of cattle, horse, pig and sheep breeds have

frozen semen stored.

No horse or pig BAR breeds have any embryos stored and only 20% of Goat and

40% of Cattle BAR breeds have embryos stored.

Section 5 – Notes relating to specific species and breeds

Species/Breed Notes

Cattle

British Friesian (Origi-nal)

The Original population is defined as cattle with at least 93.75% purity.

Dairy Shorthorn Excludes the Original Population and Northern Dairy Short-horns as these are reported separately.

Sheep

Badger Face Welsh From 2020 this breed is now recognised as two separately recorded registered breeds: Torddu Badger Face and Torwen Badger Face.

Black Welsh Mountain An extensively managed hill breeds of sheep so no individual registrations data are available.

Border Leicester The number of female registrations relates to the numbers of gimmers registered, not ewe lambs. 2016 data was estimated

by averaging the 2015 and 2017 data.

Brecknock Hill Cheviot An extensively managed hill breeds of sheep so no individual registrations data are available.

Herdwick An extensively managed hill breeds of sheep so no individual registrations data are available.

Lincoln Longwool

Low levels of registrations in 2002 (and subsequent low breeding populations in 2003/04) were caused by the Foot &

Mouth outbreak (standstill rules made it difficult to move rams, rearing lambs was difficult during this time). Lincolnshire was badly hit by F&M and this is a highly regional breed. This breed registers animals the year after birth so the 2002 data

relates to the 2001 births.

North Country Cheviot An extensively managed hill breeds of sheep so no individual registrations data are available.

Romney An extensively managed hill breeds of sheep so no individual registrations data are available.

Rough Fell An extensively managed hill breeds of sheep so no individual

registrations data are available.

South Country Cheviot An extensively managed hill breeds of sheep so no individual

registrations data are available.

South Wales Mountain (Nelson type)

An extensively managed hill breeds of sheep so no individual registrations data are available.

Suffolk Sheep The spike in 2014 was caused by changing to the Grassroots data source, which gives a more accurate representation of

the breed statistics.

Teeswater

Figures for 2015 and 2016 have been averaged across the

two years as staff problems meant that 2015 figures were de-flated and 2016 inflated.

Pigs

The UK’s commercial breeding base of some 500K 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 FANGR website:

Breeding operations approved to maintain breeding registers for hybrid breeding pigs

(publishing.service.gov.uk)

Mangalitza This breed first appeared in the UK when a small number of pigs were imported from Austria in 2007.

Goats

Arapawa Arapawa 2012 breeding female estimates are only based on

female registrations in 2012 (the only data available).

Cheviot (Feral)

Data are directly supplied from the researchers based on a Census carried out each year. Sexes are not distinguished so

the number of female/male registrations are estimated as half each of the total kids and yearlings. As the herd has uncon-trolled mating, the number of active sires is not known. The breeding female population is given as number of dams that

year as estimates from the Census has shown to be inaccu-rate due to differences in definition. The breeding population in 2016 is much lower due to rehoming of animals to a wide range of locations in order to reduce the size of the herd in

their home area.

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

American Quarter Horse

Only UK born, pure bred pedigree registration types have been included (i.e. at least 3 or 4 generations of purebred

pedigree). No grading up or cross bred animals are included in these figures.

Appaloosa

Figures shown are combined from the two registry authorities,

the British Appaloosa Society and the Appaloosa Horse Club UK. Only UK born, pure bred pedigree registration types have been included (i.e. at least 3 or 4 generations of purebred pedigree). No grading up or cross bred animals are included

in these figures.

Caspian Data is incomplete. Work is being done to improve coverage in future to give a truer picture of the breed statistics.

Donkeys

Only UK born, pure bred pedigree registration types have

been included (i.e. at least 3 or 4 generations of purebred pedigree). No grading up or cross bred animals are included in these figures.

Irish Draught

Only UK born, pure bred pedigree registration types have

been included (i.e. at least 3 or 4 generations of purebred pedigree). No grading up or cross bred animals are included in these figures.

Scottish Sports Horse

Only UK born, pure bred pedigree registration types have been included (i.e. at least 3 or 4 generations of purebred pedigree). No grading up or cross bred animals are included in these figures.

Section 6 – About these statistics

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

Farm Animal Genetic Resources (FAnGR) Expert Committee, 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.

Data Sources

All the annual data is reported through either Grassroots Systems Ltd., the British

Pig Association or the Rare Breeds Survival Trust. Between them, we receive annual

data from around 80% of breeds (182 out of 233 total breeds) and which accounts

for around 90% of native breeds (114 out of 129). Coverage has been steadily

increasing since the annual inventory was first developed in 2013. 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 is collected via a survey on a three-yearly basis.

Questionnaires are emailed or posted 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.

Data characteristics

The following data characteristics are collected from the inventory 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. Ex-cludes dams which had offspring which were not registered.

Sires Pedigree sires of fully registered animals in the year. Ex-cludes sires which had offspring which were not registered.

Breeding Herds Number of active pedigree herds/flocks which registered pedi-gree offspring in the specific year.

The following data characteristics are calculated using the inventory data.

Breeding female population

Species Breeds Multiplier

Cattle All 3.52

Sheep All 2.41

Goats All 5.16

Pigs KuneKune & British Lop 2.7

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 completely up to date. Therefore, 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.

Note: Due to the fact that this estimate is based on the 3-year average of the female

registrations it cannot be accurately calculated if data is unavailable for any of the 3

years. As a result there are generally fewer years where data area available for this parameter compared to the other characteristics.

Effective population

The effective population size (Ne) for each breed in the inventory is calculated using

Sewell Wright's formula. 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: http://jncc.de-

fra.gov.uk/page-4240

The formula for calculating Effective population is:-

𝐸𝑓𝑓𝑒𝑐𝑡𝑖𝑣𝑒 𝑝𝑜𝑝𝑢𝑙𝑎𝑡𝑖𝑜𝑛 = 4𝑥(𝑁𝑜. 𝑠𝑖𝑟𝑒𝑠 𝑥 𝑁𝑜. 𝑑𝑎𝑚𝑠)/(𝑁𝑜. 𝑠𝑖𝑟𝑒𝑠 + 𝑁𝑜. 𝑑𝑎𝑚𝑠)

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. The thresholds for each species are as follows:

NBAR

Species Thresholds

Cattle < 7500 Equines < 5000

Goats < 10000 Pigs < 15000 Sheep < 10000 Poultry <25000

BAR

Species Thresholds Cattle < 3000

Equines < 3000 Goats < 3000 Pigs < 1500 Sheep < 3000

Poultry <1000

for farmers and livestock breeders - GOV.UK (www.gov.uk).

Quality Assurance

For Quality Assurance reasons, results are shared in advance of publication to

members of the FAnGR committee.

Revisions

If any revisions are required to past data we will update the published results as

early as possible and provide information about these revisions in the Excel dataset.
