PD’d 180 heifers today, 9 empty so 5% empty rate, really pleased with that, our best for the spring herd so far.
Heifers were split into 2 groups of 80 and CiDR synced, the 20 smallest were put straight to the bulls. The others were served blind to the sync program and then bulls joined them 2 days after
Thought I’d update this a year later as it may help others.
The previous results didn’t represent calving, we ended up with 17 empty heifers by the end of calving which was very disappointing and similar to the previous 6 years results.
This year on the other hand we have ended up with 192 in calf out of 196
this was done on a 9 day sync program instead of a 10 day one.
extra jab of receptal was used at AI and the cidrs were done in house by ourselves due to being in lockdown.
165 were all served on one day so end of jan is going to be very busy.
the smaller ones when straight in with the bulls
Will have a proper idea of conception rates to the sync when they calve
