Can you keep boars and sows together?
“In our old, hand-mating/natural-mating systems, we typically keep the sow and boar separate,” says Thacker. “Then, when it is time to mate, we usually put them together in a breeding pen or sometimes take the sow to the boar pen, achieving what we call the 'bedroom effect. '”
How long does it take for a boar to breed a sow?

At what age can pigs get pregnant?
The female pig (sow) is ready to breed (reaches puberty) at 5 months of age and will show signs of being in heat. Some slow growing types and animals which are underfed will be older when they reach puberty. The sow will come into heat every 3 weeks throughout the year if she is not mated.
How many sows can a boar breed in one day?
If sows are weaned in groups, a boar-to-sow ratio of 1:4 for mature boars and 1:2 for young boars is recommended. In hand mating, a mature boar should be used for ≤2 breedings/day. When using natural service, a boar-to-sow ratio of 1:15–1:25 (average 1:17 or 18) is usually needed.
How to tell if a boar is ready for breeding?
He needs to be aggressive enough, breeding wise, to make a few attempts at breeding the sow, if the first few tries are not successful. There is no way to tell if a boar is ready for breeding or not other than to let him try once he looks big enough to physically accomplish the breeding.

What is it called when pigs are crossbreed?
Crossbreeding of a sort is possible in purebred pigs, it is called “outcrossing”. Outcrossing means using genetics that are from the same breed yet completely different family lines than the pigs you have. With outcrossing, you get as close to hybrid vigor as you can get while still keeping your stock all one breed.
What is a gilt pig?
A gilt is a female pig that has not had a litter of pigs yet. Once your gilt is a mom, she is now a sow (rhymes with wow). If you have a slower growing pig, like a Large Black, just like they take a little bit longer to reach marketable size, they will also take a bit longer to reach an appropriate age for breeding.
Why are crossbreeding pigs so popular?
The reason crossbreeding pigs is so popular is because it works. Crossbreeding is a great way to make sure you get the best of both parents and that the negative traits in either parent are diminished. Crossbreeding of a sort is possible in purebred pigs, it is called “outcrossing”.

They upset mating programs, resulting in the overuse of other boars or the need to run extra boars. Bad habits. Supervision of mating is necessary to overcome or prevent the development of abnormal behaviours. Often when young boars are run together they develop bad habits.
How are boar requirements determined?
Actual boar requirements would have to be determined for each herd, based on the number of sows to be mated in a given period and the boar’s replacement age. Where double or triple matings are practised, boar requirements are based on the number of sows to be mated per week.
How many sows per boar?
This is usually one boar per 20 sows with supervised hand matings, but in small herds or under extensive conditions, the ratio could be between 15 and 18 sows per boar. This is only a guide for determining the number of boars required.

Introduction
Selection of Boars
- A boar must possess both the genetic potential to improve the performance of his progeny, and the physical soundness to remain an active breeder. Final selection for young boars can be carried out when they complete their performance testing between 20 and 30 weeks of age. Production performance The production characters of growth rate and carcase quality are of int…
Boar Sow Ratio
- This is usually one boar per 20 sows with supervised hand matings, but in small herds or under extensive conditions, the ratio could be between 15 and 18 sows per boar. This is only a guide for determining the number of boars required. Actual boar requirements would have to be determined for each herd, based on the number of sows to be mated in a given period and the boar’s replace…
Mating Management
- While the age at which a young boar can first be used varies between breeds and individuals, the general rule is that a young boar should not be used for service until he is at least 28–30 weeks of age. Boars used at too early an age may have their working life considerably shortened and their breeding ability impaired. Training a new boar Many bre...
Feed Requirements
- Boars are usually fed between 2.0 and 3.0 kg of a balanced diet containing 0.55% available lysine, and a digestible energy (DE) of 12.5–13.5 megajoules per kilogram (MJ/kg). The amount fed depends on the age, weight and the amount of work the boar is doing. Supplementing the diet with omega-3 fatty acids can improve sperm quality and production, resulting in improved fertili…
De-Tusking
- Tusks on a boar are potentially dangerous to the stock hands and the brood sows. The tusk will grow approximately 2 cm every 6 months, so it is advisable to de-tusk the boar at least once a year. The usual method is to restrain the boar by means of a rope with a running noose over the top half of the snout and behind the molar tusks. By pulling tight and tying close to a post or rail, …
Reluctance to Work
- A common cause of a reluctance to work is the overuse of a boar or the abuse and overuse of young boars. It is important to emphasise the need to supervise a young boar’s first services, to make sure they are successful and that he is in no way injured or frustrated. This initial period will influence his subsequent mating behaviour. Boar mating sheets should be used to keep a recor…
Replacement
- The useful working life of a boar can extend to about 3–4 years of age, but by then he becomes too heavy to mate anything but old sows. He is more prone to leg weakness and his breeding ability and value is doubtful. In order to maintain young active boars that are easy to handle, boars should be culled when they reach 2 years of age. As far as genetic progress is concerned, it is m…
Disease Control
- If a disease control program is being followed, it is important that the boar be included in any vaccination programs. Likewise, the control of internal and external parasites should include the boar, as he can be a source of reinfection. Consult your veterinarian to develop a suitable health and vaccination program for your boars.
Summary
- A boar has a tremendous influence on a farm’s productivity and profitability. In order to maximise the herd’s performance and throughput, boars should receive careful attention. While a manager may implement a suitable breeding program to utilise boars to their full potential, it is the stockperson who has the greatest impact on how well the boar will perform during his breeding l…
