Use of Stockpiled Berseem Clover as a Supplement for Grazed Corn Crop Residues

---

Abstract

In the fall of 1994, mature Charolais cross cows in midgestation were allotted to duplicate 15 acre fields containing corn crop residues or a 2-to-1 mixture of corn crop residues and berseem clover planted in 3 strips at an allowance of 2.5 acres/cow for a 140 day wintering season. Similar cows were allotted duplicate drylots. All cows were fed hay as necessary to maintain a body condition score of 5. Cows grazing corn crop residues with or without berseem clover required 2596 pounds less hay per cow than cows maintained in a drylot. There was no difference in the amounts of hay required by cows grazing corn crop residues alone or with berseem clover. Initial organic matter yield of berseem clover was nearly that of corn crop residues and did not decrease as rapidly as corn crop residues. Berseem clover had a higher organic matter digestibility than corn crop residues at the initiation of grazing. Organic matter digestibility of berseem clover, however, decreased more rapidly than corn crop residues because of weathering during the winter.
