Suffolk Sheep

Q: How to identify Suffolk Sheep?

Compare ears, muzzle, tail, feet and coat markings. Size is hard to judge without something nearby for scale, and young mammals may not have adult coloring yet. Mammal Identifier: upload a photo and compare the visible details.

Q: What does Suffolk Sheep eat?

Suffolk Sheep are plant-eaters that love to munch on grass and other plants.

Q: Why do Suffolk sheep have black faces?

The black, wool-free face comes from the breed's Norfolk Horn ancestors, which also have black faces and legs. Early on, the breed was even called 'Black faces'.

Q: Do Suffolk sheep have horns?

No. Suffolks are polled: neither ewes nor rams grow horns.

Q: What are Suffolk sheep used for?

Mainly meat. Suffolk rams are widely used as terminal sires on other ewes to produce fast-growing lambs.

Q: How much does a Suffolk sheep weigh?

In one study, adult Suffolk ewes averaged about 80 kg. Rams are usually heavier.

Q: Can sheep really recognise faces?

Yes. Sheep remembered 50 sheep faces for more than 2 years, and trained sheep recognised celebrities from photos.

Q: How far around can a sheep see?

Measured fields of view range from 190° to 306°, so sheep can see behind themselves without turning their heads. Only a narrow zone straight ahead is seen with both eyes.

Q: Why do sheep need to be shorn?

Most sheep's wool keeps growing. Without shearing it gets heavy and dirty: one sheep unshorn for more than 5 years carried 41.1 kg of wool.

Q: Is it safe to touch sheep on a farm visit?

Usually, if you follow the farm's rules and the staff's advice. Animals can carry germs that make people ill, so wash your hands with soap and water after touching sheep or their pens, and before you eat. Approach calmly from the side, never from directly behind.

Ovis aries

The Suffolk is a British breed of domestic sheep (Ovis aries) with a white fleece and a black face and legs that carry no wool. It was bred in the late 1700s around Bury St Edmunds in Suffolk, England, by crossing Norfolk Horn ewes with Southdown rams. Today it is raised mainly for meat, and Suffolk rams are widely used as terminal sires: the fathers of fast-growing lambs.

Also known as Suffolk, Southdown Norfolk (historical), Black face (old local name)

Suffolk sheep abilities

Up to 306° field of view
Sideways-rectangle pupils and eyes on the sides of the head give a wide, panoramic view of the field.
- Measured fields of view range from 190° to 306°. Only 4–77° straight ahead is seen with both eyes, the zone for judging depth.
- When the head goes down to graze, the eyes roll so the pupils stay level with the ground and keep scanning the horizon.
- There is a blind spot right behind the rear, so farmers move sheep calmly from the side.
Sources [1, 2, 3, 4]
4 stomach compartments
Grass goes down, comes back up as cud, gets chewed again, then goes down for good.
- Cud is a soft ball of swallowed food that is brought back up, chewed again and swallowed again.
- A healthy adult sheep spends several hours a day chewing its cud.
- Lambs start as milk drinkers: their rumen usually starts working at 50 to 60 days old.
Sources [10]
50 faces remembered for 2+ years
Sheep tell each other apart by their faces and can remember dozens of them for years.
- In a famous study, sheep remembered the faces of 50 other sheep for more than 2 years.
- They can recognise familiar human faces too. Sheep trained on photos of 4 celebrities picked them out, even from tilted pictures.
- Sheep also passed learning tests that scientists use with monkeys, such as switching to a new rule.
Sources [15, 16, 17]
Timbre the ID code in each bleat
Ewes and lambs know each other's bleats, even when they can't see each other.
- In field tests, ewes and lambs answered recordings of their own family's calls.
- The code is in the call's average pitch and the mix of its sound energy, which gives each bleat its own timbre.
Sources [9]
Smell the only ID check at the udder
Close up, a ewe checks a lamb by smell before she lets it drink.
- Ewes care only for their own lambs and push away lambs that aren't theirs.
- At the udder, the check is by smell alone. From further away, sight and sound do the job.
Sources [9]
< 2 min per sheep for a pro shearer
Wool keeps growing, so a shearer clips the whole fleece off in one piece, usually once a year.
- A skilled shearer takes under 2 minutes per sheep. The record is 37.9 seconds.
- Shearing keeps sheep comfortable and healthy. Chris, an Australian sheep that went unshorn for more than 5 years, carried 41.1 kg of wool.
- Sheep with long fleeces are sometimes shorn twice a year.
Fleece weight
Typical yearly fleece≈ 5 kg
Shrek, New Zealand (old record)27 kg
Chris, Australia (record)41.1 kg
The typical yearly fleece is for sheep in general, not only Suffolks.
Sources [12, 13, 18]
142–152 days of pregnancy
After about 5 months of pregnancy, a ewe gives birth to one lamb, twins or sometimes triplets.
- About 70% of a lamb's growth before birth happens in the last month of pregnancy.
- In one study, newborn Suffolk lambs stood up after about 24 minutes on average. Blackface hill lambs took 13 minutes.
- In its first 24 hours, a lamb needs first milk (colostrum) equal to about 10% of its body weight.
Sources [14, 19, 20]
⅓ stretch before the crimp springs back
The fleece traps a layer of dry air next to the skin, like a built-in duvet.
- Wool soaks up water vapour but repels liquid water, so the air next to the skin stays dry.
- Its natural crimp lets each fibre stretch by up to a third and bounce back, so the fleece stays springy and full of air.
- Just after shearing, a sheep has lost most of that coat, which is why shorn sheep may need shelter in cold, wet weather.

Up to 306° field of view
- The pupils are wide, sideways rectangles. With eyes on the sides of the head, this gives a broad, panoramic view for spotting danger.
- When a sheep lowers its head to graze, its eyes roll in their sockets so the pupils stay roughly level with the ground.
- Sheep can see behind themselves without turning their heads: measured fields of view reach up to 306°. But they are poor at judging depth.
- There is still a blind spot right behind the rear, so never walk up directly behind a sheep.
Sources [1, 2, 3, 4]
0 horns, in ewes and rams
- A Suffolk's face is black and free of wool. Early on, local farmers simply called the breed 'Black faces'.
- Both ewes and rams are polled, which means they grow no horns.
- One parent breed, the Norfolk Horn, also has a black, wool-free face, but both of its sexes grow spiral horns.
Sources [5, 6, 7]
- Sheep can turn their ears towards a sound to listen more closely.
- From a distance, a ewe finds her own lamb by sight and by its call, and the lamb finds her the same way.
Sources [8, 9]
Hours of cud-chewing every day
- Sheep bring swallowed food back up as a soft ball called cud, chew it again, then swallow it once more.
- A healthy adult sheep chews its cud for several hours every day.
Sources [10]
- Ewes and lambs can recognise each other from their bleats alone, even without seeing each other.
- The 'name tag' in a bleat is its average pitch and the mix of its sound energy: the call's timbre, like the quality that makes your friend's voice sound like them.
Sources [9]
⅓ stretch, then spring back
- The Suffolk's fleece is white. The breed is raised mainly for meat, so its wool is a side product rather than the main prize.
- Each wool fibre has a natural wave, called crimp, that lets it stretch by up to a third and spring back.
- Wool soaks up water vapour but repels liquid water, so it keeps a layer of dry, insulating air next to the skin.
- Wool keeps growing until it is shorn. One sheep that missed shearing for more than 5 years carried a 41 kg fleece.
Sources [6, 11, 12, 13]
4 stomach compartments
- A sheep has one stomach with four compartments: the rumen, reticulum, omasum and abomasum.
- That four-part stomach is what makes sheep ruminants, like cattle and goats.
- A newborn lamb lives on milk. Its rumen and reticulum usually start working when it is 50 to 60 days old.
Sources [10]
80 kg average Suffolk ewe in one study
- In one study, Suffolk ewes averaged 80 kg, against 54 kg for Scottish Blackface hill ewes.
- Suffolk lambs grow fast, so they are ready for market early or can be grown on to heavier weights.
- Breeders value Suffolk ewes for their milk and wide pelvis, though in one study Suffolk lambs needed help being born more often than hill-breed lambs.
Sources [5, 14]
- Like the face, a Suffolk's legs are black and free of wool.
- The breed society praises the Suffolk's hard hooves, which help keep feet healthy.

A year with a Suffolk flock

Sheep breed with the seasons, so a flock's year follows the length of the days.

Autumn
Breeding season
Shortening days switch on the ewes' breeding season. A ewe comes into heat about every 17 days until she is pregnant.⁠[19]
Winter
Growing lambs
Pregnancy lasts 142–152 days. About 70% of a lamb's growth before birth happens in the last month.⁠[19]
Late winter–spring
Lambing
Ewes give birth to one lamb, twins or triplets. Suffolk lambs stood after about 24 minutes on average in one study.⁠[20, 14]
First day
First milk
A newborn lamb needs colostrum, its mother's first milk, in its first 24 hours: about 10% of its body weight.⁠[20]
About 2 months
Rumen switches on
By 50–60 days old, a lamb's rumen and reticulum are usually working, so it can digest grass.⁠[10]
Once a year
Shearing
A shearer clips each fleece off in one piece. A pro takes under 2 minutes per sheep.⁠[18]
Summer–autumn
Fast-growing lambs
Suffolk-sired lambs grow quickly, so many are ready for market early.⁠[5]

Suffolk sheep history

From wild mouflon to one of the world's most widespread meat breeds.

10,000+ years ago
Sheep are tamed
People domesticated sheep from the wild Asiatic mouflon more than 10,000 years ago.⁠[22, 23]
Thousands of years ago
Sheep spread out
Domestic sheep spread across Europe, Asia and Africa in separate waves. Primitive breeds such as the Soay are left over from the first wave; most modern breeds come from a later wave of improved sheep.⁠[25]
Late 1700s
A new cross
Farmers near Bury St Edmunds put Southdown rams with Norfolk Horn ewes. The lambs were called 'Southdown Norfolks' or 'Black faces'.⁠[5]
1797
Named 'Suffolk'
Farming writer Arthur Young wrote that these sheep 'ought to be called the Suffolk breed'.⁠[5]
1810
A breed of its own
The Suffolk was recognised as a distinct breed.⁠[6]
1859
First show classes
Suffolk sheep got their own classes at the Suffolk Show.⁠[5]
1886–1887
Society and flock book
The Suffolk Sheep Society formed in Stowmarket on 8 January 1886. Its first flock book, in 1887, recorded about 15,000 ewes.⁠[26, 5, 6]
1888
Off to America
Suffolks reached the United States, one of many countries they were exported to.⁠[6, 5]
1980s
Peak numbers
UK numbers rose to about 500,000 before falling again.⁠[6]

Suffolk vs Merino vs Dorset sheep

Three well-known breeds of the same species, Ovis aries, bred for different jobs.

Suffolk sheep vs Merino vs Dorset sheep
	Suffolk	Merino	Dorset
Origin⁠[5, 27, 28]	Suffolk, England (late 1700s)	Spain, bred up by the Moors (700s–1200s)	South-west England
Made from⁠[5, 27, 28]	Norfolk Horn ewes × Southdown rams	Older Mediterranean sheep, improved in Spain	By tradition, Merinos crossed with horned Welsh sheep
Main job⁠[6, 27, 28]	Meat: rams sire fast-growing lambs	Wool, long prized above all others	Meat, with lambs at any time of year
Best known for⁠[5, 12, 28]	Leading terminal sire in the UK and Ireland	Chris's record 41.1 kg fleece	Breeding out of season

Horns: Suffolks have none in either sex. Dorsets come horned, or hornless in the Poll Dorset, which began with a gene that appeared in 1948.

Is the Suffolk sheep endangered?

No. The Suffolk is a domestic breed and one of the most numerous sheep breeds in the world.

IUCN Red List

Not Evaluated (NE)

Trend unknown

In the UK, Suffolk numbers rose to about 500,000 in the 1980s and later fell. For 2020, the UK reported 14,266 Suffolks to the UN's breed database.⁠[6]

Domestic breeds are not on the IUCN Red List

Threats

Harder births
In one study, Suffolk lambs were more likely to need help being born and were slower to stand and suckle than hill-breed lambs.⁠[14]
Overgrown wool
Wool that is never shorn keeps growing and can make a sheep too heavy to move well.⁠[13]

What’s helping

Flock book1887
The Suffolk Sheep Society has kept pedigree records since its first flock book in 1887.⁠[5]
Care at lambing
Making sure each newborn lamb gets colostrum in its first 24 hours gives it a strong start.⁠[20]
Regular shearing
Shearing at least once a year keeps sheep comfortable and their fleeces clean.⁠[18]

Relatives with their own story

Norfolk HornNot Evaluated
One of the Suffolk's two parent breeds: an ancient heath breed now being revived in small numbers.⁠[7]
SouthdownNot Evaluated
The Suffolk's other parent breed and one of the oldest British breeds.⁠[27]
Asiatic mouflon (Ovis gmelini)Near Threatened
The wild ancestor of all domestic sheep, including the Suffolk. It is listed as Near Threatened.⁠[23, 29]
