Adams Dept, of Dairy And Animal Science Penn State The drought and atypical conditions last fall have resulted in numerous problems related to com silage quality. In some com silage, soluble protein levels are considerably below expected. These should be confirmed by testing another sample since sampling errors and laboratory errors may occur in some cases. If verified, the low soluble protein values may be related to lack of fermentation because of low moisture or sugar contents in drought-stricken areas, as well as other factors. Silage with a pH of more than 4.8 also may present greater risk of mold, mycotoxin, and other microbial problems, as well as higher dry matter losses. Acid detergent fiber (ADF) and neutral detergent fiber (NDF) are unusually low in some silages due at least in part to lack of plant growth and/or early maturing grain and prop ortionately higher grain con tent. Since energy estimates on forage test reports usually are based on fiber content, TDN and net energy values may be (DdDiN mi mmm Pennsylvania Master Corn Growers Association board member Elwood Kyper of McConnellstown does his marketing homework to get the most for his corn. the American Farm Bureau Grain Quality Advisory Com mittee.

Ann Reynolds, Amy Smith, and Sandy Bednoski through college. “We have to do as good a job as we can with what we have to work with,” Elwood said. The TDN and NEL values of com silages with hard overma tured kernels may need to be reduced by an absolute 4 to 6 percent TDN and .04 to .06 Meal of NEL per pound DM, unless other factors, such as moisture content have been used by the laboratory to adjust for hard grains. Such would not be necessary if harvesters were equipped with kernel breakers. When low fiber values occur, it is important to make certain that adequate forage NDF is present in the diet via heavier feeding of silage or other for ages And by including some by product feeds with higher NDF content in the concentrate por tion of the ration, if necessary. High fiber values may stem from pollination failure or extremely growthy com plants with a low proportion of grain, as well as excessive DM losses during storage from seepage or lack of preservation.
