[QUOTE="moses388, post: 1848034, member: 27368"] I typically breed off natural heats, but I will try to explain. [ATTACH type="full" alt="5day_cidr.PNG"]43174[/ATTACH] Heifer gets a shot of GnRH (aka- Cystorelin or Fertagyl) when the CIDR is inserted. Five days later the CIDR is removed and heifer gets a shot of prostaglandin (aka- Lutalyse or Estrumate). Then another shot 8 hours later. Consider applying Estrotect patches when you give the second PG shot. Approximately 2 days later watch for standing heats or the visible Estrotect patches. Heifers showing heat should be restrained, artificially inseminated and given a shot of GnRH. Continue watching for heats until all heifers have been inseminated. What day works to do the breeding? You should start the process 7-8 days before the breeder is available. Does not matter where the heifers are in their own cycle. Heifers will receive hormones and all will be starting from day 0. Some smear it all over their butt making it easy to see. Some could be lying down and it goes straight into the bedding pack. I'm no expert, but I hope this helps. edit - Once animals are enrolled in a TAI program, adhere to the protocols and administer shots on time. Do not remove animals from the program by breeding them early. [/QUOTE]
