Interested to hear opinions and experience using a breeding box vs a regular chute for AI. This will be my 1st try with AI, have decided to use 5 day co synch on 7 heifers and 7 day on 12 cows. I have read a little about breeding boxes and the claim is better conception rates with them. I have a low end for-most chute with automatic catch and a palp cage. Should I plywood the sides of the chute? Put a roof on it?
