Troubleshooting and Frequently Asked Questions

  • Sometimes when I squeeze, the bottle is rock hard and nothing happens

This indicates the cervix is closed and a number of things could contribute to this:

Did you re-check the lock right before the insemination?  If so, please do not do that.  If you feel the catheter is coming out and needs to be re-positioned, go ahead and re-lock the catheter; but wait the appropriate time again before squeezing!

Has a boar been in recent contact with the animal, or was a boar present during your insemination?  This is a BIG no no…

Look at the sides of the animal, is she having contractions?  If so, give her some time to relax.

Did you place your hand on her back or butt prior to the squeeze?  Please do not do this, it will stimulate the animal.

Did you move the catheter around too much when attaching the semen container?  Please be gentle or you will stimulate the cervix!

Are there people standing in front of the animals trying to watch you perform the insemination?  Your animals will get stimulated by this, it is no different than walking the boar in front of them…

Is there a group of people all trying to watch at the same time?  You will notice the inseminations go much easier when there are NOT a lot of people around.

Is this group talking loud and taking pictures?  Please stop doing this.  You can download all sorts of pictures from this website.  Flashes and noise stimulate the animals.

Are you positive the animal is in heat?  Really sure?

Any and all of the above will stimulate the animal.  For successful breeding and ease of use with the AMG catheter, your animals MUST be relaxed!

  • Sometimes when I squeeze, the semen comes back into the bottle

This occurs when there is blockage in the cervix, or the animal is not completely relaxed. If this happens for the first two squeezes, simply wait 30 seconds and try again. If you continue to have this problem, leave her and breed the next animal in line. Then, come back and try the problem animal one more time. This usually solves the problem.

  • Sometimes when I pull the catheter out, the membranes is stuck to the side of the tube.

This condition will ONLY happen if you break the lock with the cervix. This is why we teach you to put forward pressure against the vulva prior to squeezing, and also not to pull up on the catheter when letting the air in the tube flow up into the bottle. When this happens you will get a lot of back flow too, and you should re-service the animal. This is strictly operator error and is very uncommon after the first couple days of using the product.

  • Once in a while, I get a lot of back-flow

Back flow is rather uncommon to see in sows, but quite normal in gilts. The truth is, all animals will eventually give back semen they either draw in via contractions (with traditional catheters) or that which is injected with our technology.

The interesting part about our methods is ,that even when you get back flow, especially gilts, the performance does not seem to be negatively affected! This is because our insemination method instantly places semen directly in the UTJ, so once that reservoir is filled, what ever shoots back out is irrelevant. Oddly enough, this is more of a psychological issue then a performance issue…

Nobody likes to see back flow, but unfortunately it is something that happens with ALL catheters. It is sometimes more noticeable with ours, because we are injecting the dose instantly all at one time. If some is going to come back, especially in gilts, this is when it happens. Some gilts, simply cannot handle 80 ml of volume either. They have what we refer to as a “full tank” and the semen really has nowhere to go but back out…

This condition will also happen if you break the lock with the cervix. This is why we teach you to put forward pressure against the vulva prior to squeezing, and also not to pull up on the catheter when letting the air in the tube flow up into the bottle. You must move your arm with the animal when she moves forward or backwards! Otherwise she can pull of the foam and ruin your insemination… When this happens you will get a lot of back flow too, and you should re-service the animal. This is strictly operator error and is very uncommon after the first couple days of using the product.

  • There was no membrane when we pulled out the catheter…

Ah, this is a strange one! As long as you did not get a lot of back flow, your insemination was successful. The membranes have a way of sucking back into the catheter, making it look like they never deployed. We were fortunate to get a video of this taking place in Brazil and we show it to you immediately below in slow motion…



  • Can we reduce the semen concentration per dose with this technology?

Absolutely YES! A number of studies have been conducted on this subject; first and foremost being that with JSR in the UK. An article surrounding their work is immediately below:  Click the article to go directly to the Pig Site…

  • Can we use our current timing protocols with the AMG?

That all depends on what they are!  We have spent years studying the proper relationship between AI timing and ovulation. We strongly urge you to follow those recommendations for optimal results… Please refer to our PCAI timing protocols section to see our detailed instructions on this matter.

  • We followed your timing suggestions but our performance went down!

The ONLY logical reason for this is how you categorize your weaning day. Our protocols are based on the wean day being “0”, but we surveyed people around the world and have found that about 50% of you look at the wean day as being “1”. Since there is a 24 hour difference between the two opinions, the timing for people using “1” as the wean day will be off in their schedules compared to our research and what we teach. 

  • Can we do a single-dose insemination with the AMG?

We do NOT recommend single-dose inseminations unless you are using an ovulation agonist. Without the help of such medications, your heat detection would have to be PERFECT every time and we don’t feel that is doable consistently. Here again, do your own research. If you are currently  using 2.7 doses on average, cut down to 2 for all animals and see what happens. If you experience the same performance, try a group with a single dose and see if you fall off a cliff… If you want to go down this path, I personally recommend you service the animal based on when her “2nd” dose would normally be administered so you are not breeding her too early… Also understand that if you have a high turn-over with employees, your heat-detection will vary and make this more difficult to maintain! This is a risky undertaking; please proceed with caution!

  • Do these work with frozen semen?

Absolutely YES! Since frozen semen is already stressed from the thawing process, the use of the AMG catheters will undoubtedly improve the performance of frozen semen… As discussed in many areas on this site, the immediate injection of semen directly to the UTJ by the AMG prevents the semen from undergoing phagocytosis in the horns, and not being attacked by leukocytes. Common sense says this will help improve the performance of frozen semen in the same way we improve performance with fresh!

  • Do these catheters work well for Show Pigs?

Absolutely YES. Just ask Kathy Stiger Sheidler at Sugar Creek Farms! She has been using our technology for years and would be happy to blog with you… Sugar Creek Farm’s Facebook page.

  • Can these catheters be reused?

First of all, we all know the risks of disease transfer, so just like every other catheter in the world you should not reuse the AMG Series!

Add to that, our membrane somewhat self destructs inside your animal every time it herniates to safely go through your animals cervix. The membranes are designed to herniate at the point of any obstruction or blockage; so if you tried to reuse the catheters, previously stretched membranes from the first use would prevent that from happening a second time.

  • Why do these catheters cost more than regular catheters?

1. Our catheters weigh approximately 4 times more than regular catheters. This means our material costs are much higher than normal catheters. We must use the larger diameter tubing to make room for the membrane inside, and to help with the hydraulic properties of the technology.
2. Our membranes are manufactured under strict quality controls.  
3. AMG Series catheters must be assembled by hand in order to protect the delicate membrane inside; allowing you to safely penetrate your sow and gilt’s cervix. Most traditional catheters are manufactured on automated lines and have no imported parts to drive up the cost.
4. The flexible membrane all by itself, costs more than a traditional catheter (retail price) to manufacture.
5. The AMG Series catheter is the only Patented swine catheter in the market. In order to protect our incredible technology “globally”, maintenance fees are involved.
6. The truth is, regardless what our catheter costs, you and your farm will appreciate considerable profits due to our product’s effectiveness and improvement in your farms performance.
AMG Series catheters consistently provide up to 1.5 more live-born piglets, and 5%+ higher farrowing rates compared to what you are getting now. Therefore, ask yourself how much is a weaned piglet worth? How much do you make when selling market animals? And finally ask yourself how much does the AMG Catheter cost? Take whatever profit you normally make per animal, then subtract the cost of the catheter(s). Obviously you will see a profit and the technology has proven to make you money.
That said, your profit is actually much greater than the simple calculation you just performed. You will farrow more animals, you will have larger litter sizes (live born animals) you will save feed costs on non-productive sow days, you will save money by using less water, less medication, you can save on semen cost by reducing sperm concentrations, you will either save money on labor costs or be able to better utilize your farm staff in other areas, and you will save even more money by not having to breed animals again that do not get pregnant.
When you consider all these factors, you will then understand the AMG Catheters do not cost you more. They are an investment in your breeding program and ultimately will provide you and your farm with a great deal of profit. Please look at the big picture of what we allow you to do, and don’t only look at input costs. Increased production is the bottom line and what you should be concentrating on; not saving a few pennies up front when you purchase catheters.

Please play with the profit projection spreadsheet in our profit calculator and see for yourself. All formulas in our spreadsheet tool are viewable and completely editable. If you do not agree with our thinking, then please change the formula(s) to your liking. There is an old saying that a small % of a big number is still a big number; and that certainly holds true with what our product provides you when you calculate the new profit it creates.
