How Long Do Sheep Live? Fascinating Lifespan Facts You May Not Know

Domestic sheep (Ovis aries) are one of the most widely used livestock animals.

These gentle creatures were one of the first domesticated animal species to be utilized for agriculture in the world. Sheep are raised for their wool, fur, food, and milk.

Some sheep live in captivity, and some sheep live in the wild. Sheep are tiny ruminants, mammals, and even-toed ungulates. Ruminants have four stomachs with horns that create a lateral spiral and wool that is tightly crimped. A sheep is a creature with a thick coat of fleece (wool) covering its entire body. This animal species has a broad range of colors, which is one of the important characteristics of sheep.

Sheep (Ovis aries) live in the wild such as Death Valley, California, as well as Nevada, Texas and northern Mexico, and are brown in color. Domestic sheep are available in a wide range of colors, from pure white to dark chocolate brown, and even speckled or brindle coats. Domestic sheep (Ovis aries) are popular due to their white wool that can be easily dyed. Colored sheep, on the other hand, may be seen in many sheep breeds and may even be a recessive feature in the white flock. A flock is a collection of sheep.

Domestic sheep farmers grow their flock by building fencing houses, shearing sheds, and other infrastructure by providing a nutritional diet and water. Sheep are mainly raised by farmers for commercial purposes like wool and for their meat. Meat lambs are usually slaughtered between the ages of five and eight. These sheep live before slaughter for five years. Domesticated sheep are mammals, like any big dog breed, that have a life expectancy of approximately 10-12 years old. Some breeds of sheep, on the other hand, can live for more than 20 years.

The Average Lifespan Of A Sheep 

A sheep or goat's normal life expectancy is 10-12 years, similar to that of a big dog breed. The length of time an animal is anticipated to survive is referred to as its lifespan. The lifespan of these animals usually rises as it grows in size. Cows, for example, live longer than sheep. Sheep have a life cycle of 10-12 years, similar to big dog breeds. Merino sheep, for example, are known to live longer than other kinds. The oldest sheep, according to the 'Guinness Book Of World Records', survived to reach 23 years old. She'd been a Merino for a long time.

The world's oldest sheep species, according to the 'Guinness Book Of World Records', died at 23 years old, more than twice the normal sheep's age. The number of teeth in the different sheep breeds can be used to predict their lifetime. Sheep typically have four pairs of incisors on the lower jawbone, a dental pad or no teeth on the upper jaw, and around 24 molars or grinding teeth near the back of their jaws. As a result, most ewes in a flock are culled before they reach their normal lifespan. In order to create a place for younger sheep, it's also important to get rid of elderly ewes. Animals that are younger are typically genetically superior to those that are older.

Ewes are generally culled at a younger age in severe conditions, for example if fodder is scarce, since once their teeth begin to wear and break down, it becomes more difficult for them to maintain their physical condition and eat enough forage to feed their lambs. If a ewe has access to food and is healthy, she can be productive past the age of 10. Examining the top incisor teeth can help establish a sheep's approximate lifetime. A young lamb has eight baby (or milk) teeth or temporary incisors on their lower jaw when it is born. They only have a dental pad on their top jaw, which is devoid of teeth.

The central pair of baby teeth are replaced by a pair of permanent incisors at the age of one year. Permanent incisors replace the second pair at the age of two. The third and fourth sets of baby teeth are replaced between the ages of three and four. A sheep's mouth is full of teeth when it is around four years old. The incisor teeth will begin to expand, wear, and finally shatter as the lamb reaches the age of four. A 'broken mouth' ewe is defined as one that has lost part of its teeth. It is referred to as a 'gummer' after it has lost all of its teeth. Because it chews feed with its molars rather than its incisor teeth, a sheep without incisor teeth can survive. It will, however, have a tougher time grazing, particularly in short vegetation.

Life Stages Of A Sheep

There are many additional words for different life stages of sheep (Ovis aries), most of which are connected to lambing, shearing, and aging. Sheep breeds can be reproductive all year if they are fed properly. In two years, a healthy, well-fed ewe can give birth to six or more lambs. In the spring season, female sheep (ewes) commonly give birth to one to two lambs. Within minutes after being born in the spring season, a young sheep or lamb will attempt to stand and walk. The lamb is also separated from the herd and placed in an enclosure with its mother to allow them to bond.

Lambs are born without teeth most of the time. They should have eight milk teeth by the time they are two months old. As they are mammals, the lamb also begins feeding on its mother's first milk, known as colostrum, during this period. Lots of vitamins, lipids, and carbs are found in the colostrum. It also helps to keep illnesses at bay and cleanses the digestive system. Lambs should be nursed as much as possible during the first 10 days following birth. However, some lambs are unable to breastfeed and must be reared on a bottle.

Weaning, or the process of transitioning a lamb's diet from mother's milk to solid food, can occur at any time between the ages of 5-14 weeks. Lambs are allowed to remain with their mothers until they are around five months old. They are known as weaners at this time, and they begin eating hay, grass, or grain. Hoggets are lambs that are older than weaners but not quite adults. They are similar to adolescents or teens in that they must continue to progress and become self-sufficient from their mother. When sheep attain the age of one year, they are considered fully developed adults.

The productive lifetime of sheep, on the other hand, is often significantly shorter. This is because a ewe's output peaks between the ages of three and six, and then begins to drop beyond the age of seven.

Oldest Living Sheep

The oldest sheep (Ovis aries) ever recorded was 28 years and 51 weeks old, according to the record-keeping agency. This ewe died in Wales in 1989, only a year after giving birth to her 40th kid.

Taliesin, near Aberystwyth in Wales, was home to this crossbred sheep. After lambing more than 40 times successfully, the sheep gave delivery to a healthy lamb in 1988 at the age of 28.

A ewe that was once thought to be a candidate for the title of 'oldest surviving sheep' has passed away. Methuselina, a sheep of great age, died after falling over a cliff on the Isles of Lewis and Harris, off the coast of Scotland. Methuselah, a 25-year-old sheep of Scottish Blackface ewe that died 11 months after falling from a cliff in Scotland, died nine years ago.

The blackface sheep's (Twiggy) ear tag indicated that she was just a month away from 26 years old. John Maciver, Methuselina's owner, has spoke about her life and death. Maciver credits Methuselina's long life to the health and existence of her teeth, which allowed her to graze freely into her old sheep age. He claimed she was always a skinny sheep. The sheep was dubbed Twiggy because of her scrawny look. She was discovered dead on the rocks near Garry Beach.

Her owner credits her long life to the fact that a female sheep retains the majority of her teeth, which she can utilize for grazing freely. The majority of sheep do not survive for more than 12 years. This ewe was discovered dead on a seashore near Lewis, in the Western Isles. The sheep was a year younger than Mr. Maciver's eldest son, who is 27, and older than two of Mr. Maciver's adult children, who are 23 and 24 years old.

A Polwarth-Dorchester ewe in Australia died at the age of 23 in November 2009, six months after a severe heatwave.

Threats To A Sheep’s Life Span

Non-predator fatalities among sheep can be attributed to old age, whereas lambing issues such as dystocia are the primary causes of mortality among lambs. Pasteurellosis, caused by either Mannheimia haemolytica or Bibersteinia trehalosi, both common commensals found in the pharynx and tonsils, is a common cause of unexpected and early mortality in sheep.

Lambs can become ill at any time and die fast if no action is taken. Bloating, fatigue and a lack of appetite are some warning signals that indicate a sheep may die. Predation, in addition to parasites and illness, is a danger to sheep and the profitability of sheep on the farm. Sheep, in comparison to other livestock animals, have a limited ability to defend themselves. Even if sheep escape the attack, they may succumb to injuries or fear. Predation, on the other hand, has a wide range of effects depending on the location.

Clipping fleece may be traumatic, and it's typically done with little concern for the wellbeing of sheep. Animals that have recently been sheared, for example, maybe exposed to the scorching sun. Shearing frequently causes damage to sheep and can aid in the transmission of illnesses, particularly those affecting the skin. Clipping hair in pregnant ewes in the winter is occasionally done to allow more of them to be crammed into housing, although this might cause them to become chilly. The theory is that winter-shorn sheep would flock to a barn to snuggle together and gain weight. However, with mud and urine, they run the danger of contracting and transmitting illness, such as foot rot, within the sheds.
