Smooth transition to a new feed crop starts with analysis per back-to-basics guidelines. For example, separate the evaluations between the grass portion of your corn and the high- moisture grain. Open your mind, though, to new strategies, advises Dr. Bill Mahanna, coordinator of global nutritional sciences for Pioneer Hi-Bred. New testing methods are providing valuable information on degree of kernel … Read More
While harvesting snaplage is not a new practice, it is becoming more appealing, says Dr. Bill Mahanna, coordinator of global nutritional services for Pioneer Hi-Bred. A leading reason is the advent of new, large silage choppers utilizing snapper heads with kernel processors. Primary benefits are improved tonnage with very good digestible fiber and high kernel starch. Pioneer has recently completed … Read More

Improved fiber digestibility can be a major benefit of chopping corn silage higher, according to Dr. Bill Mahanna, coordinator of global nutritional sciences for Pioneer Hi-Bred. While raising the cutting bar reduces tonnage, Bill points out the nutritional gains can be substantially rewarding. Specific adjustments should be determined case-by-case, and he suggests what factors should drive those decisions. He also … Read More
Should the cost of purchasing corn silage be driven by quantity or quality? Dr. Bill Mahanna, coordinator of global nutritional sciences for Pioneer Hi-Bred, believes in retiring the 30-year-old rule of thumb, the Board of Trade price for corn times six or seven. Current lab methods and credible indexes are more accurate in determining relative values to dairy operators and fairly compensating silage growers. Bill details various pricing opportunities in a spreadsheet, which he’s willing to share. For a copy, e-mail him at firstname.lastname@example.org.
