[QUOTE="pdfangus, post: 753385, member: 6543"] I agree. my goal for several years has been 70% single service conception. wait two weeks and turn out our home raised cleanup bulls. limit the breeding season and select for fertility. The phd's say that fertility is not highly heritable but I have seen enough anecdotal evidence to believe that if selected for, it shows positive results. synchrony drugs will aid in moving cattle up even if they do not cycle well and breed to the AI. I would say that 30 days post partum I have induced heats with synchrony. I am not a synchorny professional and my reputation is not on the line so I can say I have done it at 30 days but would agree that longer is better. I have become a big believer that presynchrony has a lot of benefit. for several years i resynced nonresponders and bred them on time with very good results. [/QUOTE]
