Do you have any information on feeding corn syrup with a hay processor that holds six bales? Specifically, can you provide ideas on setting up a system, rate of feeding and effects of cold weather.

The syrup most likely comes from ethanol plants and is called solubles. Solubles are high in protein, energy — about 20 percent fat and fat is high energy — water (about 70 percent), phosphorus, and sulfur.

Because of the high sulfur content, you need to control intake. Because of the high fat content, you need to control intake in high-forage diets. The fat content should be 5 percent to 5.5 percent of the diet on a dry matter basis.

The high water content will cause the syrup to freeze or become very think in cold conditions. Because of it specific gravity, it will not flow well by itself.

Store the syrup underground or above ground in a tank that is painted black. Consider protecting it from a north wind by bales.The tank needs to have a recirculating pump as solubles will settle.

We have a transport tank in which we can put 5 to 10 pounds of pressure, and the solubles flow well even in cold weather. Several old anhydrous tanks have been cleaned really well and rigged them for about 20 psi air pressure and a sprayer. The results have been good.

You could feed up to 6 pounds per head, per day dry matter (20 pounds per head, per day, as-fed basis – 6.0/.30 = 20 pounds of hay per day at 30 percent dry matter, 70 percent moisture). Most people are feeding less. When feeding solubles, you need no phosphorus supplementation. You may need some calcium. Limestone is a cheap source for that mineral.
