Cattle Insert (progesterone)
We have CIDR’s, applicators and information about the procedures to use these products. Contact us for more information.

Cattle breeding is more successful with the EAZI-BREED™ CIDR® Cattle Insert (progesterone). It improves the timing and efficiency of beef cow and heifer breeding programs when using LUTALYSE® Sterile Solution (dinoprost tromethamine). The EAZI-BREED CIDR Insert provides precise control of the estrous cycle, allowing more cattle to be bred in less time.

The EAZI-BREED CIDR Insert is indicated for controlling the estrous cycle and ovulation in beef heifers and cows for:

Breeding programs using the EAZI-BREED™ CIDR® Cattle Insert and LUTALYSE® Sterile Solution (dinoprost tromethamine) can:

• Provide tight estrous synchrony so animals come into heat in a narrow window
• Provide an opportunity to induce a fertile estrus in non-cycling cows
• Hasten the onset of puberty in virgin heifers

Using EAZI-BREED CIDR Inserts can result in:

• Higher pregnancy rates
• Earlier calving season
• More uniform calves
• Less involuntary culling of non-pregnant cows
• Better use of time and labor during both breeding and calving
• Tighter calving intervals, with more calves born during a cow’s lifetime
• Easier and more accurate heat detection, or the option of no heat detection with timed artificial insemination (AI)
• Enhanced use of AI
• Greater genetic gain and higher value calves
• Ability to time heifer calving first, before older cows freshen, so heifers can get extra attention
• Easier customized matings – including the use of calving-ease sires – because AI is more feasible
• Confirmed breeding and calving dates – not always possible with natural service
• A more profitable herd

EAZI-BREED™ CIDR® Cattle Inserts contain 1.38 grams of progesterone in elastic rubber molded over a nylon spine. They are packaged in a plastic pouch with 10 inserts to a pouch. The special EAZI-BREED CIDR applicator is packaged separately.

EAZI-BREED™ CIDR® Cattle Inserts are administered intravaginally, one per animal, in beef cows and heifers. The EAZI-BREED CIDR Insert releases progesterone during the seven-day treatment period. To assure satisfactory synchronization, an injection of LUTALYSE® Sterile Solution (dinoprost tromethamine) must be given to all cattle one day before insert removal. Removal of the insert on treatment Day Seven results in a drop in plasma progesterone, triggering estrus within three days.
