Introducing the Renco Preg-Tone Series 6 - The Ultimate Ultrasonic Pregnancy Detector

Experience the new and improved Renco Preg-Tone Series 6, equipped with an exciting new feature that allows you to select the animal you want to test. Say goodbye to the hassle of watching lights or pushing buttons - our advanced technology ensures a fast, safe, and accurate detection process with ease.

This state-of-the-art ultrasonic pregnancy detector is designed for a wide range of mammals weighing over 8 lbs, including swine, sheep, alpacas, goats, rabbits, foxes, and more. Its exceptional capabilities offer numerous benefits for farmers and breeders:

  • Identify non-producers and low producers at the earliest stages, preventing feed wastage.
  • Confirm pregnancy in animals during purchases or sales, ensuring transparency and peace of mind.
  • Optimize operating efficiency by utilizing expensive farrowing installations more effectively, leading to substantial savings.

How does it work? Renco's patented PREG-TONE utilizes high-frequency sound waves called ultrasound to detect the presence of amniotic fluid during pregnancy. When the fluid is detected, the instrument emits a loud continuous tone, providing a clear indication of pregnancy. In contrast, when used on a non-pregnant animal, it produces an intermittent recurring tone, ensuring good skin contact.

Experience unrivaled accuracy with no room for doubt. The PREG-TONE guarantees 100% accuracy between 30 and 45 days, depending on the animal type. But don't just take our word for it - leading universities worldwide have tested and validated the PREG-TONE against other ultrasound instruments, highlighting its superiority in terms of accuracy and user-friendliness.

Let's take a closer look at the PREG-TONE's testing capabilities for different animal types:

  • Swine: Begin testing as early as 18 days, with positive results for large litters (11-12 piglets) at this stage. Open sows can be diagnosed as early as 30 days, while the normal testing time for sows and gilts ranges from 30 to 73 days.

  • Sheep: Start pregnancy testing in ewes at 35 days, with most diagnoses made by 45 days. Testing can also be performed in the normal standing position, providing accurate results at 60-65 days.

  • Goats: Testing may begin at 30-40 days on the right side. Apply oil to the test site and position the probe 2 inches (5cm) in front of the rear leg and 1 inch (2.5cm) above the teat. A continuous tone indicates pregnancy, while an intermittent tone confirms good contact. Dairy goats like the Oberhasli can be tested as early as 20 days.

  • Alpacas: Testing can commence at 30-40 days. Alpacas and llamas are tested on the left side, with the option to try the procedure on the right side if necessary. Simply place the probe 6-8 inches (15-20cm) down from the udder (5 inches or 12cm for maidens) and aim it straight into the abdomen, following the shape of the abdomen.

PREG-TONE makes testing effortless and efficient. No lights or buttons are involved, ensuring your attention remains focused on the animal. A short, intermittent tone indicates good contact, while a loud, continuous tone confirms pregnancy. You can easily clip the PREG-TONE onto your belt or keep it in your pocket for convenience.

Constructed with durability in mind, the PREG-TONE features rugged all-metal construction. Its heavy-gauge aluminum body guarantees immunity against interference from radio waves, a common issue with other ultrasound instruments. Despite its robustness, the PREG-TONE remains compact and lightweight, easily slipping into your pocket for on-the-go convenience.
