On farms where both crops and livestock are produced, the residue remaining in corn and sorghum fields after harvest can often provide 100 or more days of grazing with little supplementation. In many cases, grassed waterways, terraces and field boarders may further add to the amount of forage available. Crop residues are not high quality forage (especially if weathered) but they are usually the most inexpensive feed available. Strip grazing allows more efficient use of crop residues. Founder, nitrate toxicity and (with sorghum) prussic acid poisoning are possible animal disorders, but are unlikely with residues of mature crops.
