http://www.bae.ncsu.edu/programs/extension/publicat/wqwm/ag61.html Guidelines for Feeding Broiler Litter to Beef Cattle Beef cattle producers searching for ways to lower feed costs and/or stretch feed supplies should consider broiler litter as a possible nutrient source for wintering, growing, and finishing rations. When fed in nutritionally balanced rations, broiler litter is a valuable source of crude protein and minerals for beef cattle. A. Dry, pregnant cows: Feed 35 to 40 lbs. of the litter-silage mixture per day. B. Lactating beef cows: Average milking ability (beef type): Feed 45 to 50 lbs. of litter treated silage per day. Superior milking ability (dairy x beef): Feed 50 to 60 lbs. of litter treated silage per day. If cows do not consume this level of feed, 2 to 5 lbs. of corn may be fed with 45 to 50 lbs. of litter treated silage per day. C. Stocker calves: Full feed of the litter treated corn silage. Grow your own, or, choose pastured/grassfed!
