Ammonia can help NEWARK, Del. European dairy fanners have found a way to improve the palatability, digestibility and feed value of mediocre hay, straw, cornstalks and other forages by treating them with liquid or gaseous ammonia. Delaware dairy farmers observed the practice in Scandinavia last summer during a tour of Norway and Denmark. University of Delaware extension dairy specialist George Haenlein, who organized the trip, says the practice can also be profitable for U.S. dairy, beef or sheep farmers. In contrast to older forage treatment methods which used corrosive sodium hydroxide or acids, Haenlein says the new ammonia procedure is cheaper, simpler and safer. Besides predigesting the fiber, it also improves feed value by increasing available energy and protein. The practice is very timely for U.S. producers, the specialist says, because of feed shortages stem ming from last year’s drought and winter kill of annual forages. The practice is a good way to stretch available poor quality forage supplies and improve herd performance especially of heifers and dry cows.

Results varied with type of forage but generally were equal to medium quality hay. The following procedures were developed by agronomy and dairy researchers K. Moore and E. Jaster at the University of Illinois Agricultural Experiment Station. Haenlein recommends that Delmarva beef and dairy farmers use this sytem if they want to try treating their forage. The only supplies needed are a sheet of 6- to 8-mil plastic large enough to cover the stack, or plastic bags to hold large round bales, plus reservoirs for the ammonia, a hose and regulator. The size of the stack to be treated depends on the farmer’s feed requirements, but for practical reasons, is limited to the amount of forage that can be covered by a 40 x 100-foot sheet of plastic. This equals about 1,500 small square bales, or 70 large round bales. The bales can be stacked directly on the ground, but it’s better to place them on a concrete slab or sheet of plastic. Choose a site that drains away from the stack. Treatment procedure “As you stack the bales,” says Haenlein, “place the reservoirs management team by the cor poration’s President, Dale M. Weaver.

The size and number of reservoirs required will depend on the amount of residue to be treated. About 20 percent of the liquid ammonia injected will vaporize immediately. The rest will remain in the containers as a liquid, vaporizing over time.” Ammonia weighs 5.14 pounds per gallon, so about 9.5 gallons of reservoir capacity is needed for every ton treated at the recom mended rate of 60 pounds per ton. For bigger stacks, two large watering tanks will work. Since ammonia will corrode galvanized tanks, use older ones and line them with plastic. For smaller stacks, 55-gallon barrels open at one end will do the job. Run a hose from each tank to an area outside the stack where it will be connected to a regulator. It’s a good idea to anchor the reservoir end of the hose with a brick since the am monia will be discharged under pressure. After stacking the bales, cover them with plastic. “This is easier to do on calm days with the help of a few extra hands,” the specialist says. “Leave enough plastic around the edges so that you can anchor it with crushed limestone, soil, or loose bales. If you stack on top of another sheet of plastic, roll the edges together before sealing. The seal must be tight enough to prevent ammonia loss. On large stacks, weight the top with a few loose bales or old tires to keep the wind from whipping the plastic.” Follow safety tips Next, punch a hole in the plastic for each hose and pull it through. Tie the plastic securely around the hose with a piece of twine. Connect the hose to the regulator and set the gauge for a flow rate of 600 pounds per hour. At this rate, A. L.

Watch for leaks and patch them with duct tape as they occur. After treatment, the forage must .remain covered for a period of time to obtain the full benefit of the ammonia. At ambient tem peratures above 60 degrees F this will take three to four weeks; at lower temperatures, four to eight weeks. “Leave the stack covered until it’s needed,” Haenlein ad- Joel Weir, of Carnation Genetics, right receives Distinguished Alumni Award from Raymond K.
