Their are 4 stages to copulating, erection and pretrudtion of penis, mounting and fixation, intermission ejectulation , and pelvic thrust on mounting. When in heat the tail on the ewe is fat and make it hard for the ram to penetrate. Experience ram moves the tail over so the penis can penetrate the vagina. e then hole the ewe with his front legs (as he on top of her) and begin to thrust, and ejectulate.

Sexual behavior largely depends on hormones. Ewes in heat will seek out a ram and closely associate with him, rub neck & body against him, and stand for mating. In ram they would follow the female, rubbing against the side of the female, biting the her wool, nosing the genital region and sniffing her urine then extending the neck with uncurled lips, running the tongue in and out, and raising and lowering one front leg in a stiff-legged striking motion.

A ewe in estrus will seek out the ram. The ram will Curl up his lip, which is called the "flehmen response." If the female is receptive, she will stand for mating. The ram might fail in multiple attempts to mount the ewe. He also tend to mate with the same ewe. Rams will tend to select older ewes over younger ewes and sometimes will choose ewes of their own breed over ewes of another breed.

During breeding season Rams are very aggressive to other rams and humans. Rams will head butt other rams onset of heat in ewes.This is a way for rams to get into physical shape for the breeding season and to establish (or re-establish) the dominance hierarchy. Testosterone plays a part in this behavior. Ram will charge head on at each, and will continue until one ram gives up

Maintaining libido is a must to have an efficient breeding program. It's mandatory when dealing with natural mating, hand breeding, or collecting semen. Male sheep can show temporary waning of libido after each ejaculation. urge in libido when exposed to a female encourages polygamous males to shift their attention from one female to another when breeding.

Ewes should be synchronized prior to insemination.  Estrus synchronization is an artificially induced hormone causes groups of sexually mature and cycling females to come into heat (estrus) and ovulate at approximately the same time. This is done to optimise conception rates within ewes. The use of teaser helps to bring ewes into season and can improve conception rates. Rams produce a chemical substance called a pheromone, the smell of which stimulates the onset of estrus. When ewes and rams are in constant sight, or smell the pheromones are much less effective at inducing estrus.

Artificial Insemination (A.I.) | Paragon Veterinary Group

# data[].attributes.attachment_link.description
Sheep are inseminated laparoscopically (a camera inserted into their abdomen) that allows semen to be transferred directly into each horn of the uterus. Fresh or frozen semen can be used for A.I. Ewes of known breeding status are the best candidates for A.I; gimmer hoggs can be used but should ideally have been in season prior to insemination.

wes are normally timid and easily frightened, but they will defend their young even if the attacker is formidable. This video shows a mother ewe protecting her lamb from an intruder (trying to steal her young). The mother ewe head butt the other ewe and places her body in front of the intruder to keep her away from her young.
