Eating leftovers helps people save money while enjoying nutritious meals. Similarly, beef producers can extend grazing days by allowing cattle to graze on crop fields after harvest, according to veterinarians at the Kansas State University Beef Cattle Institute.

On a recent Cattle Chat podcast, K-State veterinarians Brad White, Bob Larson, and Scott Fritz, a veterinary toxicology specialist, discussed this practice. They noted that crop stubble offers a valuable feed resource for cattle, though its nutrient quality declines the longer cattle remain in the field.

Beef producers should monitor grazing fields and provide supplements to their herds as needed, especially later in the winter when additional protein may be required. While crop stubble is a valuable feed resource, it also presents potential risks.

In dry years, drought-stressed forages can accumulate nitrates, posing a poisoning risk to cattle. Field testing is crucial in arid regions to ensure safety. Conversely, overly wet fields can lead to mold growth, increasing the likelihood of mycotoxin issues.

Producers are advised to walk through fields before allowing cattle to graze, assessing the overall quality and checking for grain spills that could pose hazards.

In addition to checking for grain spills, producers should evaluate water sources and grass strips before turning cattle out to graze. Ensuring surface or underground water sources are functional and clean is essential for providing fresh water to the herd.

Grass strips around the field should also be inspected for weeds or noxious plants. When setting up hot wires to contain the cattle, producers should verify that the grazing area is free of harmful vegetation.
