A.S. Series 77-17
Questions are sometimes raised about the nutritional quality of silages which are harvested and put up in South Dakota. Therefore, chemical data on 1973-75 samples from throughout South Dakota were averaged and subjected to statistical treatment by the coefficient of variation methods. Comparisons were made with United States values on similar feed as reported in the Atlas of Nutritional Data on United States and Canadian Feeds and published by the National Academy of Sciences (NAS, 1971). Total digestible nutrient values (TDN's) were calculated on the South Dakota feeds by use of the digestion coefficients listed in the NAS (1971) reference.
