Was reading a while back in a Bonsma group on FB about predicting the sex of a calf by how the hair lays down the back/spine of a cow in the last trimester.
Heifer = hair standing up
Bull = hair laid down
Anyone looked at this? It grabbed my interest. Was a result of the calfs hormones influencing the cow IIRC.
The cow that calved last night had hair laying down on the spine. It was indeed a bull calf. 50/50 chance of getting it right.
The one to calve the next day or two has hair standing up on her spine. That'd indicate a heifer if there's any merit to this.
