If you prove your pigs for meat , the idea of spawn them , either by keeping a wild boar or through AI upbringing , has in all likelihood scotch your mind . After all , it is ordinarily much more economical to have your piglets born on the farm than to buy them elsewhere .
However , it can be thwarting and stressful when your sow or gilts give out to get pregnant the first , second , third , or more prison term . While one failure to get pregnant might be a fluke , a sow that repeatedly does not come into hotness or take up breeding can be a preindication of a serious job .
So how do you know what the issue is – and whether you should step in ? Here are some of the most common pig infertility problems and how you could address them .
Why Are My Pigs Not Getting Pregnant?
Whether it ’s a failure to get pregnant in the first place or miscarriages , spontaneous abortion , or abortions that are sham your litter , here are some of the most vulgar causes to keep an eye on out for .
1. Viruses
There are a fewdifferent virusesthat can induce sterility in pigs .
These let in :
There are medicinal drug and treatments for some of these viruses but not all . To prevent them , be sure to quarantine any Modern arrivals to the farm and dole out any available vaccination .
2. Bacterial Infections
Several bacterial contagion can make sterility in pigs , too . Fortunately , most of these can be treated with antibiotics and prevent with full sanitation exercise . The most common bacterial agent to affect fertility include :
In some case , if you ’re doingAI raising , the semen can be contaminate with bacteria , too . That ’s why only working with a reputable stock breeder and being certain to conform to all handling instructions is so important .
3. Parasites
Getting your sows and gilts on a solid deworming schedule is important if you want to ensure healthy litters of piglets . Pigs should be dewormed on a regular basis , regardless of whether you are using born dewormers or you choose to use a chemical substance mathematical product .
Eperythrozoonosis is the most uncouth parasitic broker to affect fertility but it ’s certainly not the only one .
4. Nutritional Deficiencies or Toxicities
Nutrition is another vulgar culprit behind pig infertility .
female should have a good body score when they ’re bred – you do n’t want them to be too fatty , nor should they be too sparse . Feeding needs to be spot - on or a sow might not implant enough or enoughviableyoung fertilized egg .
compensate close-fitting attending to the quality of your feed . Deficiencies in vitamins and mineral like zinc , vitamin B12 , riboflavin , pantothenic acid , and choline can all cause upbringing problems . Selenium perniciousness is another possible issue to take in out for , though not as common as deficiencies of anyother nutrient .
5. Mycotoxin Contamination
Many farmers do n’t imagine about the function that mold and fungi play in pig infertility , but it ’s important to realise that they can make a serious trouble . mycotoxin , which are triggered by fungi and mould , are often present in straw bedding as well as in grain .
All kinds of animal , including those that are not engender animals , can be vulnerable to the impacts of mycotoxins . However , pregnant sow are some of the most probable to stand problem . mycotoxin can cause stillbirth and miscarriage because they damage the placenta . Often , mycotoxins make abortion before you even know your sows are pregnant .
Sanitation is one of the best ways to combat this job . launder and dry provender bins on a regular basis and make indisputable they ’re totally dry before you re-introduce them to the sloven barn . Do n’t use stubble if it was baked in damp conditions and reckon adding binders to your feed , which helps to suck dangerous mycotoxins .
6. Poor Management
Often , pigs ca n’t be cover because the direction is poor . For example , if you have too many pig living in the same b or if you practice hapless handling techniques ( such as moving them too close to breeding or moving them badly ) .
Another common understanding why a sow can not be breed is that you missed the rut cycle or mistime it . pitiable heat sleuthing is one of the most common causes of perceive Sus scrofa sterility , specially when you ’re breeding sows via AI breeding .
Even if you ’re using a boar , you should not introduce a boar until the sow is definitely in standing passion or standing oestrus . expect until your sow stands rigid and does n’t move forward when you put free weight on her back . Usually , this is on the 2nd day of the cycle .
The service period should also be highly regimented , with a sow served 2 or 3 time 12 hours apart . This will ensure the bully odds of gestation .
If you ’re using a board , attempt to supervise the service . I cognize , it ’s not the most enjoyable way to spend your time – but it ’s crucial to make certain the breeding is as planned out as potential . memorialize all service activities so that you have a expert idea of when your sow will become pregnant and start to show signs .
7. Age Issues
If your gilding has not amaze meaning yet and you ’re curious about why that is the case , it could just be that she is too new . Animals that are mated before 5½-6 months old are not likely to take that first breeding since they just are n’t reach maximum ovulation yet .
Do n’t just “ wing it , ” either , since gilding that are snarl when they are too untried often never catch up . You will likely sputter with fertility problem with them for the rest of their lives and they ’re also more likely to have minuscule or weak litters in the future , too .
8. Seasonal Issues
lastly , know that the atmospheric condition can also work a big role in whether your Sus scrofa get significant .
If you ’re engender animals outdoors , this can be problematic especially if the conditions is extremely hot and particularly if you ’re breeding with boar .
Boars , in especial , are n’t very warm of mating when the atmospheric condition is hot .
While you ca n’t see the atmospheric condition , you should verify your pigs always have access to drink water . Ensure that the wallows and germ of shade are adequately maintained .
What Are the Odds of Pigs Getting Pregnant?
Many people assume that with pigs , like humans , it ’s somewhat challenging to get pregnant .
However , pig bed are much more “ fertile ” than humanity , meaning your success charge per unit will believably be higher , too . With human female , the odds of conceiving each cycle are about 25 - 30 % ( as long as you ’re under 35 ) .
With Sus scrofa , the pregnancy pace is around69 - 77 % , calculate on when in their cycles they are entangle .
Those are moderately full betting odds !

More often than not , mistimed rut wheel are to pick . You might be trying to spawn a pig that is too young or just not in a good standing heating yet .
If those issues are n’t to blame , next consider your management practices and nutrition . These are common issue , especially among tyro pig breeders . Plus , they ’re the easiest to treat .

No matter how long you ’ve been in the slovenly person business , it ’s a incessant education outgrowth – you are always blend to be learn , so do n’t get down on yourself . Keep trying to pinpoint potential outlet and deal them .
With any luck , you ’ll have a litter of piggy run around in about 3 months , 3 week , and 3 day !
