Breeding sheep can be a rewarding and lucrative venture. Many people around the world breed sheep for a variety of different reasons, including wool, milk, and meat. One of the most important things to consider before you begin this type of livestock farming is the health of your sheep. Healthy males and females can be allowed to mingle, and nature will usually take over from there.
Sheep farming experts recommend that any sheep that are ill or have any other types of physical problems should not be bred. Before they are bred, both male sheep, known as rams, and female sheep, known as ewes, should be looked over by a veterinarian. If you choose to breed sheep with hoof, teeth, leg, or udder problems, these negative defects could be passed on to their offspring.
Ewes should be at least a year or two old weigh at least 70% of their expected mature weight. Females that are too young, too old, or underweight have an increased chance of having miscarriages or giving birth to deformed lambs. It is also important for them to be able to produce milk to nurse their babies, so most sheep farmers advise against trying to breed sheep with udder problems.
Rams can also be checked by a veterinarian to ensure that they have viable sperm. During breeding, many farmers who breed sheep also notice that they will usually need to eat more, since they have a tendency to tire quickly. Rams can either be purchased or rented. If you plan to breed sheep often, purchasing one or more may be more economical and easier in the long run.
Ewes that are ready to mate are referred to as being "in heat." Depending on the types of sheep you will be breeding, this usually happens around every 17 to 21 days and generally lasts for about a day. When she is in heat, a ewe will typically pay more attention to a ram, wagging her tail at him, nuzzling his underside, or sometimes even mounting him. At this point, the males can be mixed with the females, and nature will take its course.
The first month that a ewe is pregnant is the most critical. She should be kept calm and comfortable, since stress could cause her to miscarry. For example, you should never vaccinate or shear sheep that are in their first months of pregnancy. During the fifth month of pregnancy, most pregnant ewes will need extra grain, since this is the month that the lamb will grow the most.
At the end of the fifth month, usually the ewe will give birth. Signs that labor is about to start will begin a couple of days before, and can include discharge from the vagina as well as swelling. Ewes may also keep their distance from the other sheep, and some may paw at the ground.
The first part of the labor, the dilation of the ewe's cervix, will typically not last longer than four hours. After the water breaks, the lamb will often be born, front feet and head first, within an hour, and the placenta should pass within three hours after that. Ewes that do not give birth within two hours of their water breaking may need assistance.
After a lamb is out, the mother should start cleaning it's face and bonding with it. If she does not do this, she may be ill or possibly ready to give birth to another lamb. With the exception of keeping them comfortable, the ewe and her new baby should not be bothered. Also, rams should be kept away from the newborns, since there is a chance that they could hurt them.
