A ram is a male sheep, not a goat.1Sheep 101. Sheep terminology A male goat is a buck or a billy. The mix-up is understandable, since sheep and goats are close cousins that split from a shared ancestor millions of years ago.2Heredity. Allozyme divergence and phylogenetic relationships among Capra, Ovis and Rupicapra (Artyodactyla, Bovidae)
Ram, Ewe, Buck and Billy Name Every Sheep and Goat
- Male sheep: ram
- Female sheep: ewe
- Young sheep: lamb
- Male goat: buck or billy
- Female goat: doe or nanny
- Young goat: kid
- Castrated male: wether, a word used for both sheep and goats
The overlap comes from slang. Sheep farmers sometimes call a ram a “buck,” so hearing that word alone doesn’t always tell you which animal is meant.3Sheep 101. Sheep terminology
A horned goat is not a ram, even when the horns look similar. The bighorn “rams” of the mountains are wild sheep. North America’s “mountain goats” aren’t true goats either, only goat-like relatives. And a team with a ram mascot, like the Los Angeles Rams, shows a curled-horn sheep.
Horns won’t settle the question on their own. Many sheep breeds have no horns, and some ewes do grow them, while many goats grow horns in both sexes. Ram horns usually curl sideways in a spiral, whereas goat horns tend to sweep up and back.
How to Tell a Sheep From a Goat at a Glance
Start with the tail. Goat tails usually point up, while sheep tails hang down. Many sheep grow wool, but goats usually have hair, though hair sheep breeds exist. Sheep also have a split upper lip, and goats often have beards. You can also watch what each animal nibbles: an animal working over the fence-line shrubs is probably a goat.
A frightened, sick, or very cold goat may clamp its tail down, so the clue works best on a calm animal walking around. Many sheep have their tails shortened when young, but even a short stub hangs down rather than standing up. Confirm it with a second sign such as the face or coat.
The face offers more clues. Sheep have a vertical groove running from the nose down through the upper lip, which lets them nibble very close to the ground. Goats lack that deep split. Beards are common on goats, including many females, but some breeds are nearly beardless, so a missing beard doesn’t mean sheep.
Scent glands give a close-up clue. Sheep have glands just below the inner corner of each eye, often with a waxy buildup.4The Open Sanctuary Project. Spot The Difference: Distinguishing Between Sheep And Goats That small pocket in the skin can look dark or crusty, so it’s easy to mistake for dirt. Sheep also have scent glands between their toes.5Sheep 101. Sheep and Goat Differences Goats lack glands under the eyes, and male goats instead have glands beneath the tail.6Sheep 101. Sheep and Goat Differences So the strong smell of a buck in breeding season comes from goats, not rams.
Some look-alikes fool people. Hair sheep without wool can look very goat-like, while some goats, like Angoras, have thick woolly coats. Wild sheep like bighorns lack fluffy wool entirely.
How Closely Related Sheep and Goats Are
Sheep, goats, and the chamois branched from a common ancestor about 5 to 7 million years ago.7Heredity. Allozyme divergence and phylogenetic relationships among Capra, Ovis and Rupicapra (Artyodactyla, Bovidae) Sheep and the wild mouflon split only about 2.8 million years ago, much later.8PubMed. The sequence and phylogenesis of the β-globin genes of Barbary sheep (Ammotragus lervia), goat (Capra hircus), European mouflon (Ovis aries musimon) and Cyprus mouflon (Ovis aries ophion) That makes sheep far closer to mouflon than to goats.
Their chromosomes show the gap. Sheep have 54 chromosomes and goats have 60.9PubMed. Chromosomal evolution in bovids: a comparison of cattle, sheep and goat G- and R-banded chromosomes and cytogenetic divergences among cattle, goat and river buffalo sex chromosomes Over time, pairs of goat-like chromosomes fused into fewer, larger ones in sheep.10Asian-Australasian Journal of Animal Sciences. Genetic Differentiation between Sheep and Goats Based on Microsatellite DNA Goats are therefore thought to be closer to the shared ancestor’s chromosome layout.11Asian-Australasian Journal of Animal Sciences. Genetic Differentiation between Sheep and Goats Based on Microsatellite DNA
When two parents have different numbers, the chromosomes can’t pair up neatly as egg and sperm cells form. That mismatch is a major reason mixed embryos usually fail early or develop poorly, though it isn’t the only problem.
Sheep and goats belong to the same subfamily of hoofed, cud-chewing animals, which is why they share split hooves, cud-chewing digestion, and a similar build. But being cousins is different from being one species. A species is usually defined by whether animals can breed and produce healthy offspring that can reproduce, and sheep and goats fall short of that.
Sheep Graze While Goats Browse
Sheep are grazers: they eat grass and low plants. Goats are browsers: they eat leaves and twigs from shrubs. On shrubby pasture, grass and low herbs make up over 70% of a sheep’s diet, while shrub leaves and twigs make up half to nearly all of a goat’s.12Small Ruminant Research. Foraging behaviour of goats and sheep on Mediterranean kermes oak shrublands Sheep switch to shrubs only when grass runs out, whereas goats shift gradually.13The Journal of Agricultural Science. Foraging behaviour and diet selection of free-ranging sheep and goats in the Negev Desert, Israel
In practice, sheep put their heads down and crop plants close to the ground. Goats reach up, pull leaves off shrubs, and may stand on their hind legs to do it. Their mouths suit the work: a sheep’s split lip handles close nibbling, while a goat’s mobile lip manages leaves and twigs. On overgrown, weedy ground, goats often eat the plants sheep leave behind.
It also shapes life for anyone keeping them. Goats are often used to clear brush and vines, but they can strip bark and kill young trees, so orchards and landscaping need protection. Sheep trim a field evenly, like a lawnmower, though they will graze favored plants down to the roots if left too long. Moving animals to fresh ground before the grass is very short keeps a pasture healthy. Goats also climb, lean on, and squeeze through weak spots, so a fence that holds sheep may not hold them.
Goats learn to change course on a detour puzzle faster than sheep.14PubMed Central. Goats show higher behavioural flexibility than sheep in a spatial detour task Shrub food is patchy and unpredictable, which favors flexible problem-solving.15PubMed Central. Goats show higher behavioural flexibility than sheep in a spatial detour task
That doesn’t make sheep dumb. They’re suited to steady grazing, and their flocking keeps them safe from predators. Goat curiosity can simply look more like intelligence, and like mischief.
Can a Sheep and a Goat Have a Baby
Sheep-goat pregnancies generally don’t survive to birth.16PubMed. Evidence against humoral immune attack as the cause of sheep-goat interspecies and hybrid pregnancy failure in the doe Fertilization can sometimes occur, but the embryo usually dies partway through pregnancy. The placenta, which feeds the fetus, develops abnormally, and the mother’s immune system isn’t the cause.17PubMed. Evidence against humoral immune attack as the cause of sheep-goat interspecies and hybrid pregnancy failure in the doe
There is one rare exception. A male sheep-goat hybrid born naturally had 57 chromosomes, between the sheep’s 54 and the goat’s 60.18PubMed. Sheep-goat hybrid born under natural conditions
News stories about “geep” often describe lab-made chimeras with mixed cells. A true hybrid has one parent from each species. A farmer with sheep and goats in one field shouldn’t expect mixed offspring.
Are Rams Dangerous
Sheep aren’t seen as aggressive, but a ram can cause serious injuries.19PubMed Central. Fatal Injury Caused by a Ram (Ovis Aries) Attack In one reported case, a 120 kg ram with a history of aggression killed its elderly owner.20PubMed Central. Fatal Injury Caused by a Ram (Ovis Aries) Attack
Butting is how rams compete for mates. Wild rams settle contests by clashing heads, and domestic rams keep that behavior, so it isn’t random meanness. Aggression rises in the autumn breeding season, when rams may treat people as rivals. A ram lamb raised on a bottle often loses its fear of people and sees humans as flock mates to challenge. Bucks can be pushy too, but they tend to rear up and strike downward rather than charge.
A ram usually backs up, lowers its head, and charges. The force of a full-grown animal can knock an adult down or break bones, and children and older people are at special risk because they are smaller or slower to get up.
Never turn your back on a ram in its pen. Avoid pushing on a ram’s forehead in play, which encourages butting. Visitors to a farm should stay outside the pen unless the owner is present, with a gate or fence between them and the animal.
Why Some Languages Treat Sheep and Goats as One
The Chinese character 羊 (yáng) names the whole goat-and-sheep group.21That’s Mandarin. Year of the Goat 2027: Chinese Zodiac Meaning, Personality & Lucky Signs When it matters, Mandarin uses shānyáng for goats and miányáng for sheep.22Wikipedia. Goat (zodiac) So “Year of the Goat,” “Sheep,” and “Ram” are all fair translations.
The separate words carry clues. Shānyáng combines the characters for “mountain” and the general group, which suits goats at home on rocky slopes. Miányáng uses the character for cotton, pointing to wool and so to sheep.
