I am new to your board, so forgive me if I am being redundant. I have tried searching the archives without much success in getting a specific answer. My scenario is this: wanting to use DDG as a protein supplement to background crossbred beef cattle (currently lactating) . Cattle have access to quality free choice mineral, salt and quality hay. Hoping to maintain body condition and timely breedback. My questions are: how many lbs per head is safe to feed? How much of a concern is the Sulfer issue? Do i need to include a gluten balancer with Rumensin (sp?) Additional info: DDG are 30-32% protein per the distributor, no real sulfer issue with my water, and my goal is to feed about 4lbs per head per day until pasture is going strong, then also supplement during dog days of summer if need be. Any advice is welcomed.
