1. At least 50 days and preferably 55-60 days post-calving -- insert the CIDR****. Day 1 (am)
2. Give 2ml of Cystorelin Intramuscularly (IM) to clear any cystic ovaries. Day 1 (am)
(Ovarian cysts are non-ovulated follicles with incomplete luteinization and can result in irregular estrus)
3. Pull CIDR Day 7(am).
4. Give 5ml of Lutalyse (IM) to heifers and cows up to 1300 lbs and 6 ml to cows over 1300 lbs.
5. Cows and heifers should show heat in the next 80 hours. Normally 24+ hours after the removal of the CIDR.
6. If no heat is seen by the 80th hour; breed them anyway.
7a. Standing heat in the morning -- breed them in the evening (pm) Later is better; than earlier.
7b. Standing heat in the evening -- breed them in the morning (am) later is better; than earlier.
*** Cows or heifers showing estrus (standing heat) 5-7 days before inserting the CIDR, should be bred on their natural heat.
Some Considerations:
Many factors contribute to the success and/or failure of a reproduction management program:
1. Cattle must be ready to breed-they must have a corpus luteum and be healthy.
2. Nutritional status must be adequate as this has a direct effect on conception rates.
3. Cattle working facilities must be adequate to allow cattle handling with low stress to the animal.
4. Estrus (standing heat) must be detected accurately.
5. Semen must be of high quality.
6. Insemination must be done properly and in the correct time frame
If you currently have any of these management deficiencies; they must be remedied first before you can have a successful breeding program. A job well done with 86% conception rates. An easy 80 hours.
