Corabelle was 3 years old in August. She had her 2nd calf the end of Oct. She has always been the kind of gal to definitely let me and any bull within 500 miles of our house that she is in heat. I take her to a bull about an hour and a half away, so getting the heat cycle down is important to me. After this last calf I sould definitely tell when she was in heat for the first two times, but more than one person said don't breed them on the first cycle as they tend to not settle (remember there is a ride involved here), so I listened. Her second cycle I was ready to go and on the Saturday she just didn't show outstanding signe of heat, so I figured it would be the next day. Saturday evening she was bawling her head off, but it could have been her "I do believe you are 30 seconds late feeding me" bawling, so I figured even if she was showing signs of heat, I'd take her the next morning. The next morning I get the trailer arranged, the bull arranged, and she acts as docile as can be. Here we are three weeks later, and she is docile out there. I've thought of AIing her, but dexter semen is about $85. per straw and again someone has told me with the bull she gets serviced more thatn once (boy that is an understatement) as opposed to a one shot deal with the AI. I've always read other posts with questions about detecting heat and thought, I can tell when mine is in heat any day of the week. Not so true now...actually she is out there bawling right now, so I should check things out. Do any of you have any ideas? Have you had good luck with AI if you hit the day right? Thanks.
