Went in the Co-op this AM and manager told me that had half of a pallet of cattle feed they needed to dispose of due to weavils. It was show calf feed. Normally $10.45 for a 50/lb bag. Bought 16 bags for $4.00 bag. As far as I'm concerned weavils are protein also. If you deal with the Co-op or feed store ask what they do with similar feed. Of course, you don't want it to be mixing species, such as feeding hog feed to cattle. But, even here, Co-op says they now use no ruminant animal by-products, such as meat and bone meal, in any of their feeds. For about the next month I will also be giving the herd chopped sweet corn stalks. On feed value vs cost, may be marginal when I consider my time and effort and pickup gas and wear and tear. Sort of like giving them a treat while it lasts. My Angus bull comes to the back of the pickup when I'm offloading waiting for me to pull off a couple of ears, shuck them back and stick them in his mouth. I have a local reputation for taking good care of my cattle.
