Spelt (Triticum aestivum ssp. spelta) also known as dinkel wheat or hulled wheat, is a species of wheat (Triticum aestivum ssp. aestivum) that has been cultivated for over 8000 years.
Corn (Zea mays L.) is nowadays the main cereal grain included in dairy cow diets in the US. Nonetheless, the cold weather of the west of Canada and some of the European countries is not adequate for cultivating corn, being wheat (Triticum aestivum L.), the main cereal grain produced in those areas.
