Cattlemen's Day, 1983; Report of progress (Kansas State University. Agricultural Experiment Station); 427; Beef; Calcium oxalate; Alfalfa; Clovers; Soybean meal; Cottonseed meal
Alfalfa, clovers, soybean meal and cottonseed meal have part of their calcium tied up as insoluble calcium oxalate. The oxalate crystals are relatively unavailable to animals and could be an important consideration in ration formulation. Extension dairymen presently are discounting total alfalfa calcium by 40 %.
