I have a situation I've not had before and need advise and/or to know if anyone else has had this happen.
I had a cow in standing heat early morning on May 16 and bred her late that evening. I usually stick on a second Estrotect patch at about 17 or 18 days after A.I. to help me check heats, but on day 16 I thought she was acting like she was coming into cycle so I stuck a patch on her. She acted a bit bullish for that evening but nothing rode her and her patch remained un-rubbed. On June 14th, 29 days post breeding, I pulled a blood sample for BioPRYN testing. This past Thursday the sample report came back as "pregnant" with a score of .21.
Today, 19 days from when I thought she was displaying signs of heat, she is standing for one of my bull calves (about a 450 lb calf) and acting bullish with the other cows. From all classic signs she is in standing heat.
The main points:
- She calved on Feb. 25th, so she was well past any postpartum days requirements at over 110
days.
- She was the only sample I pulled or sent for sampling. I have not preg-checked any other
cattle to date so no chance of mixing samples or mislabeling.
- The test is 95% for positive outcomes, with most negatives a result of too-early sampling or an embryo lost later after testing. Her blood was just tested last Tuesday / Wednesday so I think embryo loss and heat in the last four days unlikely, and I already mentioned she is over 110 days postpartum.
I don't want to leave her open, but I also do not want to A.I. a pregnant cow. Not sure what to do. Any help appreciated.
