Nutritive Value Of Drought Soybeans As A Forage UNIVERSITY park (Centre Co.) Drought or immature soybean plants can be satisfactorily as a forage crop. Plants should be allowed to mature as much as possible before harvesting. Some pod or bean devel opment enhances feeding value of plants harvested either as hay or sil age. Soybean forage is high in calcium and should be avoided as the major forage source for dry cows. If the plants are going to be ensiled, it is recommended to do so before the plant moisture drops below 60 to 65 percent. As with any forage crop, it is most critical to have adequate mois ture levels in the crop at ensiling to achieve a proper fermentation. This may require chopping some and checking dry matter content with a mi crowave oven or Koster Tester. If plants are high in moisture and lack pod or bean development, and if it is possible, add 100 to 200 pounds of a ground grain per ton when direct- >*• *x f lare Bale Baler 8575 1000 Lb.

The ground com or other grains will add carbohydrates to the crop to help with fermentation. The cow will then use the energy from the grains when the crop is fed. The stems of soybean plants are not very palatable and animals will sort them out if given the opportunity. It is best to feed soybean silage in a TMR system. Silage may have to be chop ped finer to minimize sorting of the stems even if used in a TMR. If using the Penn State Forage Panicle Separa tor, recommended ranges should be no more than 10-15 percent greater than .75 inch and 30-40 percent in the .75 to .31 inch range. Another possibility is to make soy bean hay. If soybean hay is made, it is best to use this hay in a total mixed ra tion to help prevent sorting. Soybean hay can be unpalatable under many circumstances. This can be more diffi- cult to work with as leaf shatter nw SSSL& Model 8590 Get More From Your Baler.

It may be difficult to dry down pods for hay if beans are too well developed. It is critical as with any forage to analyze soybean silage or hay for their nutrient content These can vary great ly depending on the circumstances in volved. The maturity of the soybean plants at harvest will greatly effect their nutritive content. Fat content should be analyzed if Table 1.
