A Stretch Tube With a Memory The Lastic Tube® system is a stretch tube with a memory. Lastic Tubes® are some of the fastest, most economical, convenient, and reliable ways to produce baled silage. The system provides a practical way to improve the palatability of soft textured baled silage. This nutritious and digestible feed is especially beneficial when back grounding calves, while also helping to reduce bloat and other digestive problems. Save Feed Over Dry Hay A study conducted by Manitoba Agriculture compared dry hay and baled silage and found a 25% feed savings by using a baled silage feed system. There is less waste associated with baled silage compared to dry hay. Baled silage is readily adaptable to most dry hay systems (such as round bale feeders) and can be unrolled in the field with less leaf loss than dry hay. Chopping and feeding from the Lastic Tube® is also an option.
