I want to be getting her incalf at day 42, not starting to try and clean her up.
I would treat from 21 days.
Why?Too slow. I'm looking for decisions from 14 d.
Why?
Don't get it what can you do at 14 daysSpeed.
Unless the vet is visiting daily, presenting cows from 21 d means they could be up to 28 d or even more if a 2 wk routine is used.
Presenting from 14 d reduces lag time.
I rest my caseYou can Metricure at 14 days.
Really,really like the sound of this procedure..and no milk withhold ! How many mls of iodine in 60 mls of water? Many years ago a vet washed out two cows with dilute iodine,problem was it wasn't diluted enough.i had two very sick cows for about a week,milk left them and they never cycled again.Personally because it is a heifer and tend to find heifers take a little longer to get in calf start as soon as possible. Using an AI sheath and a syringe put a syringe of diluted iodine through the cervix before it closes up anymore. Two 30ml syringes tends to be enough. At the same time estrumate which will bring her bulling in 2 or 3 days then her next cycle should be around 6/7 weeks when she may be ready for serving. The non milk withdrawal antibiotics should have also helped.
We have found estrumate early before the infection gets trapped as the cervix closes
But having to get cows cycling with hormones to get a 365cycle is not a fertile cow.
She may still be more productive though.
