Synchronising Heifers

Sugarbowl

Anybody successfully do this with their heifers? I’ve a few heifers to AI yet. They are cycling. What’s involved? Thanks

Mooooo

Couple of different ways. Coil in and shot of receptal day 0, pg day5, pg and coil out day 6, ai 48 hrs later on day 8 and a shot of receptal. This will have them all served on that day 8.
If they are cycling you could just give a shot of pg and watch them well anything it works on will come in 48 to 72 hrs, if timing isn't right they may come in after that in natural heat and give a shot 11 days later to those that haven't been bred and that should get the rest of them then.
Get scratchcards and stick them on if using just the pg or natural route

Day 0 coil in and receptal
Day 5 estrumate
Day 6 estrumate and coil out
Day 8 about 2 hours before serve receptal
Nb important to serve as close as possible to 48 hours after estrumate on day 6
Before and after programme steady diet no changes .what worked for me is heifers on same grass from day 0 to day 8 and then onto stronger low n grass .loiking like 94% held to that programme for my heifers this year
