Ideally, the ewes should have a body condition score of 2.5-3 six weeks prior to lambing and at least 2-2.5 at lambing.

A flock of sheep is generally mated by a single ram, which has either been chosen by a farmer or has established dominance through physical contest with other rams (in feral populations). In a case like this, 8 months can be a good first breeding age. It is a good idea to shear wooled ewes about a month or so before lambing. When a female goat gives birth, it is referred to as kidding. Gestation (pregnancy) The average gestation length in sheep varies from 142 to 152 days.  However, using tags improperly or using tags not designed for sheep may cause discomfort, largely due to excess weight of tags for other animals.

Both castration and docking can be performed with several instruments. Apart from grazing, sheep should be fed with supplemental feed of concentrate mixture @ 300 to 350 grams/sheep/day. Inbreeding depression has been found for lamb birthweight, average daily weight gain from birth until two months, and litter size. Many researchers are conducting studies to determine how manipulating sheep diets may help reduce these dangerous emissions. This can help you to separate the potentially pregnant from the definitely not pregnant sheep in your flock. DNA tests have proved that up to 10% of the lambs are sired by the surrogate ram and carry the genetics of the donor ram.

Pregnancy can also be broken down into trimesters. Anestrous period (reproductive inactivity).  While the majority of births are relatively normal and do not require intervention, many complications may arise.
