When Do Sheep Breed? The natural joining and breeding season for ewes usually lasts from about February to June. During this time, a ewe will go on heat and ovulate for a short period in regular cycles, called oestrus cycles, approximately every 16 days.
What months do sheep breed? 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). Some sheep breeds are less seasonal. They breed almost year-round or have an extended breeding season.
How often do sheep breed in a year? Since ewes gestate for only five months, it is possible for them to lamb more often than once per year. While annual lambing is most common, lambing intervals of 8 months are also realistic, especially in the tropics and with breeds that are less seasonal in their breeding habits.
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.
Dorset, Polypay, Rambouillet, and crosses of these breeds are commonly mentioned as breeds to consider for use in a fall lambing program. Other breeds also will have a certain percentage of ewes that cycle for out-of-season lambing.
Getting the ewe to stand up or elevating her hindquarters will allow more room for repositioning and result in less vigorous straining.
Texas is the largest sheep producing State, followed by California.
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.
It is convenient to wait at least 3 months after the last parturition (lambing) before a ewe is bred again. A ewe comes into first heat at 7 to 8 months of age. A ewe should not be bred when she comes into her first heat.
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.
The lamb should be delivered in a downward arc without undue force over 10 to 30 seconds. Traction is applied in an arc and the lamb is pulled “down and around” and not ‘straight out”. The lamb should be left 1-2 minutes with the umbilical vessels still intact.
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.
Ewes usually produce one to three lambs annually (gestation period of five months). It is possible to breed ewes more often than once a year when a number of factors are favorable. The ewes must be capable of breeding in the spring, fall, and winter.
Ewes are only in season once per year – so unlike other animals that become fertile multiple times a year, there is a short time period for them to fall pregnant. There are expectations for breeds like the Polled Dorset who can get pregnant all year round.
It’s rare for a sheep and goat to mate successfully, and most resulting pregnancies are never carried to term. According to Gary Anderson, distinguished professor emeritus at UC Davis, these hybrids are exceedingly uncommon between a male goat and a female sheep (as was the case with Murphy’s geep).
The lambs will stay with their mother until they are about 5 months old. At 6 months, they are considered fully grown.
If fed and managed properly, most pet sheep maintain good health and live for a long time. The natural life span of a sheep is 10 to 12 years. Some will live longer. The most common health problem of sheep, especially lambs, is gastro-intestinal parasites (worms).
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.
Birth in both cows and sheep can be successfully induced by administering both prostaglandin F2α (or its synthetic analogue cloprostenol) and the corticosteroid dexamethasone by IM injection.
Most ewes lamb during daylight hours, but management will affect when peaks occur.
With nearly X thousand tonnes, China became the world’s leading lamb and sheep meat consuming country, making up X% of global consumption. The other major consumers were Australia (X thousand tonnes) and New Zealand (X thousand tonnes), with a share of X% and X%, respectively.
Profitability can be challenging, but with productive sheep and close control of expenses, a profit is possible. Sheep produce income from the sale of meat, wool and milk. The highest-quality meat is produced from lambs, young sheep under one year of age. Most sheep are sheared once per year to produce wool.
Clearly, when you mate one ram to all the ewes in a flock, some inbreeding will naturally occur. Father/daughter crosses will not happen because you will retire a ram after breeding so that he never has a chance to breed his daughters.
Although vasectomised rams are often left in for a week (in for one week, out for one week, then introduce fertile rams is easily remembered), just two days’ exposure is sufficient and would allow their use in other groups of ewes consecutively.
A good ewe will bag up about 5-10 days prior to giving birth. Again, if you look at her every day, you’ll know what a normal udder looks like and thus, you’ll be able to tell when it’s not normal.
