I recently listened to this podcast and I found a lot of good information. It’s not just for breeders but talked about amino acids role, minerals and vitamins and how the play with each other, along with different grains all easy to understand. If you ever wanted to know what to look for on your feed tag this will help. It’s 3 hours long but divided into 1 hr segments. Grab a pen and paper because you’ll want to take notes.
