How Long Sheep Pregnant?
How can you tell if a sheep is pregnant? SIGNS OF PREGNANCY: 3 weeks later: the ewe does not come into heat. 6 weeks later: the vulva shows an enlargement. 12 weeks later: the abdomen enlarges, she looks calm and walks slowly.
What time of year do sheep give birth? Sheep are short day/long night breeders meaning they breed late summer/early fall and consequently their lambs are born in the winter and spring.
How long does the female sheep carry the baby for? A ewe is pregnant for 142 to 152 days, approximately five months or slighter shorter. Pregnancy is also called gestation. Since ewes gestate for only five months, it is possible for them to lamb more often than once per year.

Ewe lambing signs
The udder becomes engorged, swollen and slightly red. Ewe lambing signs also include the vulva stretching out and becomes red and swollen. Often, an ewe will miss a feeding or separate herself from the flock shortly before labor begins.
Getting the ewe to stand up or elevating her hindquarters will allow more room for repositioning and result in less vigorous straining.
Valbazen Suspension (11.36 % or 113.6 mg/ml): 7.5 mg/kg orally; approved in sheep with meat withdrawal time of 7 days. Do NOT use in pregnant ewes in the first trimester of pregnancy. Safe-Guard/ Panacur Suspension (10% or 100 mg/ml): Note that SafeGard is not approved for use in sheep.
The test detects early pregnancy-associated glycoproteins as a marker for pregnancy. The test is validated internationally for use in cattle, sheep, goats, and buffalo.
Pregnant women who come into close contact with sheep during lambing or other farm animals that are giving birth may risk their own health, and that of their unborn child, from infections that such animals can carry.
Most sheep are seasonally polyestrus and short-day breeders. They will begin to exhibit estrus when length of day begins decreasing. They will come into heat every 16 to 17 days until they are bred or return to anestrus. Thus, the most natural time for sheep to breed in the U.S. and Canada is the fall (Oct-Nov).
The ewe can stand up and down, but cannot turn around. Consequently the adopted lambs can suckle off of the ewe, without her running off and leaving them or pushing them away.
The ram may breed his daughters and dam. Undersized ewe lambs may be bred. Because the times of breeding and lambing will not be not known, it will be difficult to properly time vaccinations, supplemental feeding, and other management practices.
Most ewes lamb during daylight hours, but management will affect when peaks occur.
The process of giving birth to lambs is called lambing. Another word for birthing is parturition. Another word for pregnancy is gestation. A male sheep is called a ram.
In Iraq, the principal lambing season of Awassi ewes is in November, and in Lebanon, the Syrian Arab Republic and Israel in December-January. The mean gestation period in an Awassi flock in Lebanon has been reported to be 149.5 days for male lambs and 148.6 days for females (Choueiri, Barr and Khalil, 1966).
Gently push both Four legs – one head: lambs back into the uterus to allow enough room to deliver one lamb normally. Be sure the legs belong to the head of the same lamb before pulling. The second lamb may have its head back, so gently bring the head into the normal position.
Abortion/Stillborn Lambs
Abortions and stillborn lambs are usually caused by an infection like toxoplasmosis, vibriosis, chlamy diosis or leptospirosis. Lambs may also be born weak and die shortly after birth as a result of these infec tions. Infections are often a result of poor farm hygiene or poor biosecurity.
Panting assessment
This is because 65% of the heat loss in sheep occurs by panting. The degree to which sheep are panting is an important indicator of the extent to which they are suffering from heat stress (see Figure 6): Mild heat stress – sheep may show mild to fast panting, but with a closed mouth.
