Wasteage From Feeding Hay on Top of Snow Was Significant

In Canada and the Northern U.S., hay is commonly fed to cattle on snow-covered ground over the winter. The objective of this Alberta Agriculture project was to measure the losses that may occur when feeding dry hay, either processed or unrolled, on the ground versus hay processed into portable feed bunks. The trial was conducted at the Lacombe Research Centre in February, 2005. A total of 55 heifers were allotted to one of three different feeding treatments using meadow brome hay: 1) Hay processed into portable feed bunks; 2) Hay processed on to tarps covered with snow; or 3) Hay unrolled on to tarps covered with snow. Hay was supplied at 90% of expected intake to ensure the heifers cleaned up as much as they could. Snow, ice, wasted feed, and manure were gathered off the tarps after the feeding process, which was repeated four times. This material was dried, manure removed, and weighed for total hay loss. The wasted hay was sieved and weighed to determine the amount of fine and coarse material. There was no wasteage of hay processed into feed banks.
