Crimping is a cost-effective way to produce high-quality feed for all livestock. It improves profitability of the farm by reducing costs of investments (dryer, storage) and energy (oil, electricity). Production costs of crimped grain are much lower than those of dried grain.
Crimped grain is ready to feed without any further processing. It can be used directly from the storage for feeding as such or as a component of Total Mixed Rations (TMR) for cattle or in liquid feed for pigs. Ensiling of crimped grain is based on lactic acid fermentation by lactic acid bacteria. Favourable environment for lactic acid fermentation is created by lowering the pH of crimped grain to the level of 4 and by anaerobic conditions. Grain for crimping can be cultivated similarly to grain for drying, but it is harvested 2–3 weeks earlier at the yellowish stage when the grain’s energy content and protein content are at their highest. Early harvesting allows cultivation of late varieties with higher yield potential. Fertilization is also more flexible and manure can be used more freely.
