[QUOTE="cow pollinater, post: 1581451, member: 14661"] I wouldn't hesitate to go 30 days on the late calvers. You'd be surprised at how decent the results can be if they're in decent condition. It certainly won't match what you'd get at 60 days but it's a good management tool to get them cycling for the bulls and some of them will breed up. I helped a dairyman that was having reproductive problems with his fresh cow protocol for a few years. He was all bull bred. Part of my thirty day program was lut shots on a regular interval. I talked him into a dose of gnrh and breeding them at 35 days, which was the last day of the program, and averaged around three services per conception and his bulls were running around 70% on the following cycle. That REALLY sped thing up for him and took him from struggling to keep his stanchions full to selling heifers. [/QUOTE]
