Animal Reproduction Systems, Inc.

Animal Reproduction Systems, Inc. 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 colts 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.

'Tis the season! AAEP presents the countdown to foaling...

WHAT TO EXPECT WHEN YOU'RE EXPECTING (A FOAL) 🐴

If your mare has made it through 11 months of pregnancy, you're almost there. Labor and delivery, while momentous, are generally uncomplicated — however, being a prepared and informed owner will help you keep your anxiety in check so you can assist the new mother and foal get off to a great start.

Here are some things you can do to prepare for the arrival of the foal:

• Consult with your veterinarian well in advance of the birth. Know how to reach your regular veterinarian after hours and ask about a back-up or referring veterinarian in case your regular horse doctor is not available.

• Clean and disinfect the stall as thoroughly as possible. Provide adequate bedding.

• Wash the mare's udder, v***a and hindquarters with a mild soap and rinse thoroughly.

• Wrap the mare's tail with a clean wrap when you observe the first stage of labor. Be sure that the wrap is not applied too tightly or left on too long, as it can cut off circulation and permanently damage the tail.

• Time each stage of labor, to help you keep accurate track of the mare's progress. Take written notes! When you're worried or anxious, your perception of time can become distorted.

As always, these are general guidelines, and you should contact your veterinarian for more information specific to your situation. Good luck!

While we're a bit spoiled here in southern California with the mild temperatures we get during winter, we do have other weather issues which can quickly escalate to an emergency situation. The devastating firestorms fueled by high winds and dry conditions are the most recent example.

Are you prepared for an emergency where your stock will need to be evacuated? An important consideration is identification, and that you might not be present during an evacuation.

The EquestriSafe company for years has made high quality fetlock and neck bands which provide easy to read, safely worn identification that can be left on at home, or when your horses travel.

ARS remains open, and safe from the latest southern California fire storms. However, many communities to the west of us have been devastated by the powerful winds and wildfires.

We are immensely grateful for the first responders battling these conditions, and brave volunteers who have transported horses to safe locations.

Locations updated 01.10.2025

🔥🚒The ongoing wildfires in Los Angeles, including the Palisades Fire, have led to mandatory evacuations and the displacement of numerous large animals.

How You Can Help:

➡️Provide Shelter: If you have facilities like barns or pastures, consider offering temporary refuge for evacuated animals.

➡️Volunteer: Assist with animal transportation or care at designated shelters.

➡️Donate Supplies: Items such as hay, feed, water buckets, and medical supplies are in high demand. Donate through your local rescues, sanctuaries, staging areas, and designated LA Sheltering locations.

Current Large Animal Sheltering Locations:

📍Lancaster Animal Care Center 5210 W Ave I, Lancaster, CA 93536
📍Antelope Valley Fair 2551 W Avenue H, Lancaster, CA 93536

Being from southern California, it wouldn't be New Year's Day without the Rose Parade. Started in 1890 by the Valley Hunt Club, the parade continues to showcase a wide variety of both mounted and driven equestrian groups (our favorite part), marching bands from the US abroad, along with the amazing floats decked out in flowers, fruit, bark, seeds, and all sorts of clever botanical ingredients. This year, the equestrian entries include the Arabian Horse Association demonstrating the versatility of the breed from native costume to endurance racing, the Budweiser Clydesdales, International Andalusian and Lusitano Horse Association, Mini Therapy Horses, Northwest Spotted Drafts, the incredible Scripps Miramar Ranch driven and ridden entry, the US Marine Corps Mounted Color Guard, the Valley Hunt Club with their Friesian drawn carriage, our hometown Norco Cowgirls Rodeo Drill Team, and more! We hope you enjoy the parade as much as we do!

ARS will be closed January 1st, enjoying the parade, and gearing up for the new year. We'll be back in the office on Thursday, January 2nd, to help you get prepared for the 2025 foaling and breeding season.

Tune in on January 1 to see the organization that started it all. The Valley Hunt Club will ride down Colorado Boulevard featuring VHC President, Chris Cole, and his family. 🌹✨

“In New York, people are buried in snow,” announced Professor Charles F. Holder at a Club meeting in 1890. “Here our flowers are blooming and our oranges are about to bear. Let’s hold a festival to tell the world about our paradise.” ☀️

More than a century later, the parade floats are a marvel of state of the art technology, all tucked away beneath flowers and other all-natural materials. Every New Year, visitors experience the beauty of the floral floats along with spirited marching bands and high-stepping equestrian units along the 5 ½ mile route down Colorado Boulevard. 🐴

The Madigan Squeeze Technique has been a true life saver when dealing with "dummy foals". Studies have even shown this technique is effective for both cattle and camel calves in similar distress.

When checking your foaling barn supplies, be sure to include our E-Z Squeeze foaling rope (EZS-101), used for administering the Madigan Squeeze technique. Check out our new how-to video on our webpage: https://youtu.be/-oxGVrRzCYI

Foaling season is right around the corner! Preparation is the key to success when bringing those eagerly anticipated colts and fillies into the world. Evaluating mare colostrum is a quick process that can confirm quality colostrum, or give you more preparation time to locate a good colostrum source if your mare is deficient.

Our ARS Equine Colostrum Refractometer is calibrated specifically for mare's milk. It's easy to use, only requires a few drops of colostrum, and can be read immediately.

For an excellent explanation of the importance of evaluating mare colostrum, please follow this link to the article written by Dr. Pat McCue at the Colorado State University Equine Reproduction Laboratory: https://www.arssales.com/colostrum_101.html
