Improve the timing and efficiency of any breeding program. Make breeding less of a guess.


Eazi-Breed™ CIDR® ensures more pregnancies and more milk sold by improving the timing and efficiency of any breeding program. Synchronize estrus in dairy heifers and the return to estrus in lactating dairy cattle.

Improve the effectiveness of reproduction programs by tightening estrus synchronization so groups of cows and heifers come into heat and can be bred in a narrow window. Groups of cows also can be synchronized to return to estrus after insemination for potential rebreeding in a desired time frame.

LUTALYSE® Sterile Solution (dinoprost tromethamine) is the only prostaglandin product on the market approved for concurrent use with Eazi-Breed™ CIDR® in synchronization protocols of lactating beef cows.


  • More cows and heifers become pregnant earlier, resulting in higher pregnancy rates
  • Easier and more accurate heat detection
  • More focused heat detection and easier AI breeding within a narrower window of time
  • Heifers freshening at a younger and more consistent age
  • Accurate breeding and calving dates
  • Improved efficiencies in labor management

Each insert is impregnated with 1.38 grams of progesterone in elastic silicone molded over a nylon spine. Inserts are packaged in a plastic pouch with 10 inserts to a pouch.

A special Eazi-Breed™ CIDR® applicator is provided separately (#540051).

Always Read & Follow Label Directions.

    We have used these for the last 5 years with great success. We have increased our conception rate significantly. I would recommend this product and it is worth every bit of $115!

    These little things have revolutionized our breeding program. They are very effective and bring our cows into a very strong heat. Our AI success rate has increased since we started using these.
