EAZI-BREED™ CIDR® Cattle Insert

EAZI-BREED CIDR

Getting cows cycling again just got a little easier. Eazi-Breed CIDR® Cattle Insert is now approved for the induction of estrous cycles in anestrous lactating dairy cattle.

Eazi-Breed CIDR helps to improve the effectiveness of reproduction programs by tightening estrous synchronization so groups of cows and heifers begin cycling and come into heat and can be bred in a narrower window.

Groups of cows also can be synchronized to return to estrus after insemination for potential rebreeding in a desired time frame. LUTALYSE® Injection (dinoprost tromethamine injection) is the only prostaglandin on the market approved for concurrent use with Eazi-Breed CIDR in synchronization protocols of lactating dairy cows.

  • Use of Eazi-Breed CIDR can result in several improvements to a reproduction program:

    • Induction of estrous cycles in anestrous dairy 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.
  • For Induction of Estrous Cycles in Anestrous Lactating Dairy Cows:

    • Anestrous dairy cows can be identified using any of the following methods:
      • Cows not observed in estrus since calving.
      • Cows diagnosed twice without a corpus luteum on either ovary via ultrasonography at a 7 to 14 day interval, such as on Day 35 and Day 42 post calving.
      • Cows with low concentration of progesterone in two blood or milk samples collected at a 7 to 14 day interval, such as samples collected on Day 35 and 42 post calving.
    • Administer one Eazi-Breed CIDR per anestrous cow and remove 7 days later (for example if administered on a Monday remove the following Monday).
    • If insemination is intended, observe cows on Days 2 to 5 after removal of the Eazi-Breed CIDR Cattle Insert and inseminate animals found in estrus following typical herd practices.

    For Synchronization of Estrus in Lactating Dairy Cows:

    • Administer one Eazi-Breed CIDR per animal and remove 7 days later (for example if administered on a Monday remove the following Monday).
    • Administer 5 mL LUTALYSE at the time of removal of the EAZI-BREED CIDR Cattle Insert.
    • Observe animals for signs of estrus on Days 2 to 5 after removal of the Eazi-Breed CIDR and inseminate animals found in estrus following typical herd practices.

    For Synchronization of the Return to Estrus in Lactating Dairy Cows Inseminated at the Immediately Preceding Estrus:

    • Administer one Eazi-Breed CIDR per animal 14±1 days after insemination. Remove Eazi-Breed CIDR Cattle Insert 7 days later (for example, if administered on a Monday remove on the following Monday).
    • Observe animals for signs of estrus on Days 1 to 3 after removal of the Eazi-Breed CIDR and inseminate animals about 12 hours after onset of estrus.
    • Note: Do not administer LUTALYSE to cows for synchronization of the return to estrus, as this will interrupt pregnancy that may have occurred at the immediately previous insemination.

IMPORTANT SAFETY INFORMATION FOR EAZI-BREED CIDR: Avoid contact with skin by wearing protective gloves when handling EAZI-BREED CIDR inserts. Do not use in heifers of insufficient size or age for breeding or in cattle with abnormal, immature, or infected genital tracts. Do not use inserts more than once.

IMPORTANT SAFETY INFORMATION FOR LUTALYSE: Women of childbearing age and persons with respiratory problems should exercise extreme caution when handling LUTALYSE. LUTALYSE is readily absorbed through the skin and may cause abortion and/or bronchiospasms, therefore spillage on the skin should be washed off immediately with soap and water. Aseptic technique should be used to reduce the possibility of post-injection clostridial infections. Do not administer LUTALYSE in pregnant cattle unless cessation of pregnancy is desired.
