Submitted by: agcomm, Wed Nov 26 10:13:38 1997 November 26, 1997 Whole Kernel Corn Offers Feeding Options With hay supplies short in some areas of the state, whole-kernel corn offers a feeding alternative that some cattle producers may want to consider. "We had some producers who were very short of hay last year who used whole-kernel corn with pretty good success," says Chip Poland, a livestock specialist with the North Dakota State University Dickinson Research Extension Center. Poland says those experiences are backed up by research at Ohio State University that showed that a large part of the hay in beef cow rations could be replaced by shelled corn. Producers may be able to feed 10 to 12 pounds of corn each day to replace more than 25 pounds of hay in the typical ration of up to 32 pounds of hay per day. "We can't get totally away from hay, but shell corn can go a long way toward stretching short hay supplies," he says. "This is an example of how different crops in the region offer cattle producers new feeding strategies and opportunities." Cattle can utilize whole shell corn more efficiently than barley or wheat in high- concentrate diets, Poland notes. Barley and wheat need to be processed before feeding to get the most energy out of them. Corn, on the other hand, can be used effectively with little or no decrease in diet digestibility. Poland says the Ohio research shows that at $2 per bushel, producers can substitute shell corn for good quality hay when hay is selling above $45 per ton. A 20 cent move in corn prices will change the break-even hay price by $2 per ton. In other words, if corn sells for $2.80, limited feeding of corn can replace $53 per ton hay in a typical cow ration. Poland notes that feeding whole-kernel corn requires additional management. Overconsumption can result in acidosis, bloating or excessive weight gain. This can be a problem particularly when processed grains are fed. "With limit feeding, you have to provide the grain and hay so that all the cows get their fair share." he says. "That's a real concern for producers who aren't set up for this type of feeding system." In addition to a small amount of hay, cows fed a ration high in whole-kernel corn will need a protein supplement. "In many cases, the composition and price of that supplement are the keys to making this feeding strategy work," Poland says. In the original Ohio research, soybean meal and corn made up the base of the protein supplement. Opportunities exist for using more locally available protein sources in the formulation of the supplement. "Cull field pea and lentil, as well as other oilseed meals, are available locally in North Dakota that may help cheapen the cost of the supplement," he says.
