A Slect Sires specialist came down and ate Thanksgiving dinner with us yesterday. There's a few new protocols for AI whether it's using timed or observed heats. I had a breeding question for him that he's never been asked before. What is the best lunar cycle to set up cows for timed AI? And has there been any studies on moon phase and conception rates? The answer was no to both questions. I feel working with nature while setting up cattle for AI might help on conception rates.

I don't know about conception rates but there is a difference in how much activity you see in heat detection based on lunar cycle for sure! I will see if I can get ahold of a dairy manager that I had as a customer for around fifteen years that loves questions like this. I'll bet he would break it down for us with thousands of observations in dairycomp.

Thanks Okie this kind of stuff wears on my mind. Everything in nature is controlled by the lunar cycles and if a person can figure out when and where the times are best for hunting and fishing it becomes a lot simpler.

If you calve on a schedule, you have to take what ever astrological conditions exist when your breeding season is upon you. For example, I want my calves born the first three weeks of September. I start about the 25th of November and get them done as soon as I can. I would not change my schedule to fit the lunar cycle. |

If you calve on a schedule you usually don't breed on the cows first cycle. Seems to me it would be easy to set all your cows up to breed within a 24 hour window. Any time between a new moon and full moon is optimal timing, I'd like to be 3 - 6 days before the full moon. |

I begin breeding about the 22 day of November. That is 60 days postpartum. By that time they are past their first cycle. Thus, by November 22, they are coming into their second cycle. Some will even be on their third cycle. |

 You might have a couple come in early but the majority will be all together. |

You might have a couple come in early but the majority will be all together. I have thought about it. But it is amazing how tight they are on natural heats. I had 25 to breed this season and I had about 18 of them serviced in the first 10 days. I use the 7 day CIDR protocol when I have one not cycling. |
