[QUOTE="Bright Raven, post: 1612747, member: 27490"] Blood of ovulation discharges are usually 2 days after estrus activity or one day after estrus behavior at the earliest. Assuming you have experience doing Artificial Insemination (it appears you do), it is rather odd that you are breeding during the time of bleed-off from ovulation. I suspect there may be another source of the bloody mucus. Thus, the following question. You bred her on 11/30. There was bloody mucus on the rod. Was she bred on 11/30 following a synchronization protocol involving the use of a CIDR? If you had her set up with a CIDR, a CIDR can sometimes irritate the vagina resulting in small amounts of blood and sometimes even white blood cells. I rarely use CIDRs, but I had a case very similar to yours. When I pulled the CIDR, there was a small discharge that came out in front of the CIDR. I proceeded with the protocol and it was successful. If the source of the blood is the vagina, it will not interfere with conception. If the source of the blood is uterine, in that case, blood can act as a spermicide inside the uterus. The source of the blood could be related to many scenarios but this heifer could be having some vaginitis due to the irritation of the CIDR. [/QUOTE]
