Abstract
Conclusions:
- The value of a forage to an anilmal is influenced by the physical form in which it is fed.
- Measured in terms of animal performance, long or chopped hay can be improved by grinding and pelleting. Much of this improvement appears to be due to grinding.
- By grinding and pelleting an ordinary quality forage, feed intake may be increased by as much as 25%, daily gain by 100% and feed efficiency by 35%.
- The digestibility of individual nutrients in forages may be altered slightly by changing the physical form but the net effect is small. Grinding and pelleting a forage reduces the digestibility of the crude fiber.
- Harvesting forage and feeding as soilage, silage or hay may increase animal gain or production per acre, but not per animal.
- Various factors, such as stage of maturity, weather conditions, equipment used, and storage facilities, attending the process often have more influence on the feeding value of a forage than the particular method of harvesting and storing used.
