Ultrasound wands
If your Vet is using an ultrasound wand in the fall and you calve in the spring, this is not only useless at predicting fetal age but also has a high probability of calling bred cows open. The probe can not pe*****te that deep and so I would ask them to hand check all opens. I have also seen a high incidence of re**al tears. I assume this happens when the cattle have been on dry feed and poor water and there is not much moisture to the f***s. I think the wand has its place and helps save our body, but it has limitations that might cost you money.
Ultrasounding should be done between 30- 100 days in cows and 30- 90 days in heifers for best results on fetal aging and between 65- 90 days for fetal sexing.
