great presentation, Mike
you mentioned that too high a vit d level also created issues in young pullets,
Can you further discuss what level did you see problems, and what form of vit d?
also in layers what did you see when too high or low, and what would you recommend in layers?
thanks, Mike
Thank you Mike for a good presentation, I would like to ask what ingredient do you use from day-old chick to make sure at the point of lay the dietary vitamin D is available?
