There are many varieties of hemp, most of them grown for fibre or in some areas for the oil-rich seed. The seeds are usually pressed twice, first without heat to obtain a clear green cooking oil, and then with heat to obtain a brown industrial oil. As the seeds contain chlorophyll, the press cake is green if the meal has not been overheated in the processing. The cake can be used for feed, but it is mediocre owing to the presence of shell debris. USE. In countries where hemp is grown, the seeds are used for cattle and poultry as a concentrated energy feed. The very low digestibility of the fibre component of the oilcake limits its use, especially in pig and poultry feeds. It is therefore used mostly for fattening cattle (up to 3 kg per day) and adult sheep (0.5 kg per day).
