Summary

Fresh and ensiled lucerne and fresh bromegrass were processed immediately after collection or stored at -25 deg C for 1 day or 1, 6 or 12 months before drying at 55 deg C. Samples were frozen quickly by submersion in liquid nitrogen or slowly at -25 deg C. Freezing decreased phosphate buffer soluble crude protein and increased neutral detergent insoluble crude protein by more than 40% for bromegrass. An additional experiment showed that freeze-drying resulted in less insoluble protein than oven-drying.
