Note: In one of Aesop's fables, a wolf wraps itself in a fleece and manages to get into a sheepfold without being noticed. It then attacks the sheep and eats them. This image is also used in the Bible: `Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves.' (Matthew 7:15) See also: clothing, wolf

black sheep

A deviant or eccentric; the least successful, least admirable member of a group. Black sheep were long considered less valuable than white ones because their wool could not readily be dyed. Several sixteenth-century writers wrote of the black sheep as a dangerous (“perilous”) animal, among them John Lyly. In the eighteenth century, the application to the human deviant became common. Sir Walter Scott wrote, “The curates know best the black sheep of the flock” (1816), and “the black sheep of the family” was an increasingly common way of singling out the odd member.See also: black, sheep

hanged for a sheep (as well) as a lamb, (might) as well be

One might as well commit a great crime as a small one, since the punishment would be the same; also, do not stop at half-measures, but enjoy something to the fullest. This term comes from the times when both sheep and lamb were considered so valuable that the theft of either was punishable by death. “As good be hanged for an old sheep as a young lamb” appeared in both John Ray’s English Proverbs (1678) and James Kelly’s Scottish Proverbs (1721), and has persisted to the present day. See also in for a penny, in for a pound.See also: hanged, sheep, well

separate the sheep from the goats, to

To sort the good from the bad, the superior from the inferior. This term comes from the Bible, in which Jesus seems to make an analogy between sheep and goats and those who would sit at God’s right hand and left hand (Matthew 25:32). In the fourteenth century John Wycliffe was more explicit, stating, “Schepe that schal be savid schal be on hys rigt honde [sheep that shall be saved shall be on his right hand].” The term has been so used ever since.See also: separate, sheep

wolf in sheep's clothing, a

An enemy masquerading as a friend. The term comes from Aesop’s fable about a wolf dressing up as a shepherd (in some versions, as a sheep) and sneaking up on the flock. In the Bible, Jesus warns of “false prophets which come to you in sheep’s clothing but inwardly they are ravening wolves” (Matthew 7:15). The expression has appealed to hundreds of writers. Clare Boothe Luce (Kiss the Boys Good-bye, 1939) used it to describe a predatory male collegian: “A wolf with a sheepskin.”See also: wolf

black sheep

A disreputable or unloved family member. Since the majority of domestic sheep have white fleece, a black one would be different from the rest of the flock. And because the word “black” has a historically strong negative connotation, one of that color would be unwanted (in real life, sheep farmers don't like them because black fleece, which can't be dyed, is less commercially valuable). In the age of politically correct speech, the phrase is now infrequently used, and that's not because family members now get along in greater harmony than they once did.See also: black, sheep

sheep


sheep,

common name for many species of wild and domesticated ruminant mammals of the genus Ovis of the Bovidae, or cattle, family. The male is called a ram (if castrated it is a wether), the female is called a ewe, and their offspring is a lamb. Wild sheep, found in mountainous parts of Asia, North America, and the Mediterranean region, are agile rock climbers with large, spiraling horns. They do not bear wool. Among those species are the Asian argali, the Barbary sheep, or aoudad, of North Africa, and the North American bighornbighorn

Sheep

 

a domestic ruminant artiodactyl of the genus Ovis of the family Bovidae. Sheep are descended from wild species of sheep, including the mouflon (Ovis musimon) and the argali (Ovis ammon), which were domesticated more than 8,000 years ago. The evolution of domestic sheep primarily involved changes in the woolly covering and the body shape.

Sheep are 55–100 cm high at the shoulders and measure 60–100 cm long from the occiput to the rump. Ewes weigh 30–100 kg, and rams 60–180 kg. The rams of most breeds have large horns; the ewes are hornless or have small horns. The head has a straight or, sometimes, hook-nosed profile. Its lower part is pointed, the lips are thin and quite mobile, and the incisors are placed at an oblique angle to the jaw. This head structure enables sheep to graze very close to the ground, making better use than other animals of the pasture. Adult sheep have 32 teeth. Replacement of milk teeth begins at the age of 12 to 18 months and ends between the ages of 3½ and four years. The legs are strong, enabling the sheep to wander extensively. A sheep may be white, black, rufous, or gray. Sheep with a fine or semifine fleece are usually white.

Sheep are classified according to shape of their tails as being short-thin-tailed (the tail is thin, does not reach the tarsal joint, and has ten to 12 vertebrae), long-thin-tailed (the tail is thin, reaches the tarsal joint or sometimes lower, and has 20 to 22 vertebrae and fatty deposits), and fat-tailed (the tail has five or six vertebrae, and there are fatty deposits on the rump and around the tail).

Under favorable conditions, the life-span of sheep is 14 or 15 years; on farms they are used for six to eight years. Sexual maturity is attained at five to seven months, and the animals are allowed to mate at 15 to 18 months. With natural mating, 60 to 70 ewes are assigned to one ram; with artificial insemination, the sperm of one ram is used to inseminate more than 3,000 ewes over a period of 45 days. Gestation lasts between 145 and 155 days. Most ewes bear one lamb; some yield two or three. Romanov ewes produce as many as five young. Newborn lambs weigh 3–5 kg. Growth is completed after two to four years.

The fleece of coarse-wooled sheep consists of a mixture of coarse fibers, 100–200 microns (μ) in diameter, and thinner downy fibers. The coat of fine-wooled sheep consists of homogeneous downy fibers having an average diameter of 25 μ. The wool of fine-wooled sheep is 5–9 cm long, that of semifine-wooled breeds is up to 40 cm long, and that of coarse-wooled breeds is 10–15 cm long. The annual clip from fine-wooled sheep is 5–6 kg (record clip, 31.7 kg), from semifine-wooled sheep 3–6 kg, and from coarse-wooled sheep 1–4 kg. The yield of pure wool after washing is 30–50 percent from fine-wooled breeds, 50–65 percent from semifine-wooled breeds, and 55–75 percent from coarse-wooled breeds. Fine-wooled and semifine-wooled sheep are clipped once a year, in the spring; coarse-wooled sheep are clipped in both the spring and autumn. The best meat and wool breeds are slaughtered at five to seven months of age and yield carcasses weighing 18–22 kg. Ewes produce 50–200 kg of milk per lactation (in some breeds up to 500 kg).

Breeding work with sheep includes selection, culling, and crossbreeding and is directed toward obtaining and rearing animals with desirable qualities. The principal feeds are grasses from natural and cultivated pastures, hay (mainly small-stalked), spring straw, silage, and concentrates. Sheep are pastured from early spring to late autumn; in regions with very little snow or hot climates, the animals may pasture year-round. They are kept in special pens; structures are also set up in seasonal pastures. Sheep tolerate various air temperatures well and may be kept in high-altitude pastures. They are very sensitive to dampness and are subject to catarrhal disorders, helminthiases, and foot rot. Sheep are raised in almost all countries.

What does it mean when you dream about sheep?

Dreaming about sheep may indicate the dreamer feels uncreative and lacks initiative to venture out on his or her own. The dreamer may be just following along, letting others direct his or her life.
