CORNSTALK DISEASE.
—When cattle are allowed to run in stalk fields it frequently happens that a large per cent die from various causes. All these troubles are classed under the one term—cornstalk disease. In some western fields where there is a second growth of cane stalk late in the fall an early frost will at times develop in the stalk a deadly poison (hydrocyanic acid), which kills the animal in a very few minutes after eating it. This poison has not been found in the cornstalk.
In the last year or two some of our state experiment stations have been investigating several molds which seem to affect not only cattle but horses as well. These molds grow quite abundantly upon cornstalks, alfalfa, and other forage crops. The death of a great number of animals has been traced directly to the feeding of such affected fodder, hay, or corn. These molds, however, must have a certain amount of moisture for their growth, and it has been shown that when the feeds have been properly harvested and sheltered no trouble has resulted. Only in materials exposed to the weather, allowing the development of these lower forms of plant life, has serious trouble been found.
In the treatment of these troubles nothing reliable can be given, as the disease usually comes on without any warning and the animal dies suddenly. Much of the trouble can be avoided by allowing the animals only a limited amount of the feed or in the stalk field a few hours only each day. It is necessary that plenty of pure water should be given frequently and enough of other roughage to keep the animals from gorging themselves on the fodder.
