A Guide to Sheep Production

Sheep stay with a comparable reproductive strategy to other herd animals. A cluster of ewes is commonly mated by a single ram, who has either been picked out by a breeder or has established dominance through tangible competition with other rams. Most sheep are seasonal breeders, although a few are able to breed year-round. Ewes generally reach sexual maturity at six to eight months of age, and rams commonly at four to 6 months. Ewes maintain estrus cycles roughly speaking each 17 days, for the period of which they emit a perfume and indicate promptness through substantial displays towards rams. A marginal of sheep displays a preference in support of homosexuality (8% generally) or are freemartins (female animals that are behaviorally masculine and lack functioning ovaries).

Without human intervention, rams fight in the course of the groove to work out which those could mate with ewes. Rams, particularly unfamiliar ones, will additionally fight outside the breeding interval to ascertain dominance; rams can exterminate each other if permitted to mix without restraint. During the rut, even usually friendly rams could become aggressive towards humans thanks to increases in their hormone levels.

After mating, sheep own a gestation cycle of about five months, and regular labor take one to three hours. Although a few breeds frequently throw bigger litters of lambs, the majority churn out single or twin lambs. During or soon subsequent to labor, ewes and lambs could be confined to small lambing jugs, small pens made to aid both watchful observation of ewes and to cement the bond among them and their lambs.

Ovine obstetrics may be problematic. By selectively breeding ewes that construct multiple offspring with advanced birth weights in support of generations, sheep producers have inadvertently caused a few domestic sheep to have problem lambing; balancing ease of lambing with distinguished productivity is one of the dilemmas of sheep breeding. In the justification of whichever such problems, those present at lambing may assist the ewe by extracting or repositioning lambs. After the birth, ewes ideally break the amniotic sac (if it is not broken in the course of labor), and commence licking clean the lamb.
