Animal Reproduction Systems produces artificial insemination equipment for equine, livestock, poultry, and canine breeders.

Founded in 1980, as a division of Dupree, Inc., a company with deep roots in the aerospace industry, Animal Reproduction Systems (ARS) applied engineering science, high-tech electronics, and quality manufacturing processes to create products that set industry standards for animal breeding practices. Since our first product, the Model 534A Densimeter, known in the industry as the "Blue Box" stallio
n s***m counter, ARS has continued to manufacture and improve state-of-the-art equipment for equine, bovine, porcine, poultry, and canine breeding programs. In August 2014, Animal Reproduction Systems, Inc. was established as Doug and Kathy Thistlethwaite took over the reins of ARS. For twenty-six years Doug had worked for Dupree, Inc., in both the ARS division and as the head of their engineering department. He holds United States patents for the ARS densimeter, and has designed many of the products we carry. Doug met Kathy in 1985, in a fencing class, while they were attending California State Polytechnic University, Pomona. At that time, she was starting c**ts at the BJ Cuttin' Horse Ranch, owned by Jim and Bunny Dupree, and he was working for General Dynamics. As their courtship developed, Doug became a frequent visitor to the ranch, which later led to a job offer from Dupree, Inc. The Thistlethwaite's were established in 1988, and the rest is history still in the making. Doug, Kathy, and the rest of the ARS staff are looking forward to continuing the traditions of producing high-quality, innovative products, and providing excellent customer service to our valued clients.

During an Olympics viewing binge, the warehouse trolls discovered some mismatched 13 mm goblets. These are the same 13 mm goblets sold on our website in single colors or as a multi-pack, however these bags, in honor of the Paris Olympics and upcoming Paris Paralympics, are a special mix of red, white, and blue.
Each bag contains 50 goblets, with a mix of red, white, and blue (the trolls confirmed there are two colors that have 15 goblets, and one color will have 20) .
These bags are available at our special sale price of $22.00 each. To order, you need to CALL US at 1-800-300-5143, or contact us through Facebook Messenger. There are ONLY 3 BAGS AVAILABLE, so act quick! First come, first serve!

ARS Palpation L**e Mix (PLM-101/12) is sold dry, in 12 sealed packets that each make 1 gallon of palpation l**e. The mix takes about 10 minutes to combine with hot water using an electric drill with a paint mixer bit.
PLM-101/12 is an economical option for prepared palpation l**e, which has the added bonus of being light weight for shipping (vs. 7 lbs per gallon of prepared l**e).
Please watch our instructional video to see how to mix the l**e correctly: https://www.youtube.com/watch?v=5bogaq66E4k&t=19s
If you'd like to try a 1 gallon sample of ARS Palpation L**e Mix, put "PLM-101 sample" in the comments section of your next order and we'll include a packet. We have 14 samples available, first come, first served.
Orders may be placed at: www.arsequine.com, or give us a call at 1-800-300-5143, Monday through Friday, 8AM-4PM.

Sold in lots of 100 straws, you can choose from clear, gold, blue, orange, or green. Printing up to 53 characters per line, with 2 lines available.
We recommend using ALL CAPITAL LETTERS for easier reading. We also suggest, if you want a line for the collection date, to put it on the top line if you need to "fill in the blank" such as: _____/______/202__ Use at least 5 underline marks to give yourself room to write dates or lot numbers. Ultra fine point Sharpie pens are useful if you need to add information.
To order, go to our website: https://www.arsequine.com/custom-printed-freezing-straws

**If you place an order for other items along with printed straws, please indicate if the order can ship all together when the straws are finished. If you need your supplies right away, please make a separate order.
Organizing your storage dewar for freezing straws? ARS is here to help! We offer both 13mm and 10mm goblets and aluminum canes, as well as colored cane tabs to help you quickly identify your straw locations.

***LAST CHANCE FLASH SALE!!!*** Need a 22" or 19" Colorado AV?
NOT SO UGLY DUCKLING SALE!
We have 2 large cuff Colorado Artificial Vaginas available that have some minor blemishes. Sale price is $250 each (new models are $330). They are brand new, come with their filler cap, and are ready to be put to work.
1) SAV-102 - This is a large cuff style 22" AV, that has a factory blemish. There is a scuff mark about the size of a quarter on the outside case. Not something your stallion will be concerned about, but not up to our usual high standards in quality control. https://www.arsequine.com/22-artificial-vagina-case-with-large-cuff-filler-cap
2) SAV-102-19 - This is a large cuff style 19" AV, that has a few dried glue drips on the underside of the large cuff. Perfectly usable, but not as pretty as we like them. https://www.arsequine.com/19-artificial-vagina-case-with-large-cuff-filler-cap
FIRST COME, FIRST SERVE!!! To order online, click on the above link to the AV you're interested in. When placing your order, be sure to put "UGLY DUCK" in the comments section. We'll adjust the price before charging your credit card.

The heat is on! The AAEP provided some useful information about reducing the risks of heat related conditions.
With warmer weather arriving, fire season is upon us. The AAEP has provided an excellent reminder for fire preparation in your barn. Please share other useful advise in the comments section.
What measures have you taken to reduce fire risks in your barn? 🧯
According to the National Interagency Fire Center, in 2024 there have been 16,940 reported wildfires in the U.S. to date. As we head into the hottest time of the year, make sure your farm has a fire prevention plan and an evacuation strategy in place to keep both horses and people safe.
Check out the graphic for ten fire prevention measures to get you started on the right track to a safer facility. This list is not meant to be exhaustive and we invite you to contact your local fire department and your veterinarian for guidance on designing a prevention and response plan tailored to your specific situation.
Barn fires are the number one local emergency affecting agricultural facilities. They can cause horrific injuries and kill more horses than any other type of disaster, so being prepared is only in your best interest!
It's warming up! ARS recommends shipping cooled and frozen products (E-Z Mixin and E-Z Freezin extenders, and IgG test kits) on Monday or Tuesday to avoid delays over weekends where warm weather can quickly cook shipments.
If ordering online at www.arsequine.com, you can always put a note in the comments section to let us know you'd prefer to "Ship Monday."
When the tried and true 50 cc syringes that we carried for decades stopped being made, the Air-Tite company stepped up to the plate, and they hit a home run. These new 50 (60) cc all-plastic syringes are excellent quality, with a smooth glide, and off set nozzle. As an added bonus, ARS includes 30 caps with each box of syringes. Our supply is limited, so we are limiting purchases until our next shipment arrives in mid June.
