Dry matter loss and compositional analysis of large switchgrass round bales during ambient storage in Virginia
Two varieties of switchgrass, Cave-N-Rock and Alamo, were baled into 1.8-m diameter by 1.2-m wide round bales and stored outside for 12 months. String-wrapped bales were stored on sad and net-wrapped bales on rock. Six bales (three-string-wrapped, three netwrapped) were destructively sampled at four...
