FDA agency gives go-ahead on definition of 'hemp seed meal' for laying hens https://t.co/5WlakOQWPr via @hemptodaynews

In countries where hemp is grown, the seeds are used for cattle and poultry as a concentrated energy feed. However, the very low digestibility of the fibre component of the oil cake limits its use, especially in pig and poultry feeds (Göhl, 1982).
......Varieties grown for fibre and oil have much lower levels of THC (less than 0.2%) than varieties grown for drug production (Kahn, 2005; ITC, 2010).
No pathological side effects have been reported for the by-products of industrial hemp...
Ruminant Feed
The (seed) oil cake has been used for fattening cattle (6 pounds 9.2 ounces) (up to 3 kg per day) and adult sheep (0.5 kg per day) (Göhl, 1982).
It is an excellent natural source of rumen-undegradable protein that is equivalent to heat-treated rapeseed meal.
When substituted for rapeseed meal, hemp seed oil meal included at 20% of diet DM had no detrimental effects on feed intake or nutrient utilization by sheep (Mustafa et al., 1999).
Poultry
Hemp seeds have a high energy content, and due their low cost, are a traditional staple of mixes for pet birds.
Seed-eating migratory birds are attracted to hemp fields at harvest time, and, in many countries, the seeds have been used as poultry feed (Khan et al., 2009).
Broilers
Up to 20% dried and crushed hemp seeds have been used successfully in broiler diets and resulted in higher breast, leg and thigh weight.
This positive effect has been linked to the combination of a good protein and lipid quality associated to other beneficial properties, such as the lack of trypsin inhibitors and the antioxydant activity of cannabidiol (Khan et al., 2009).
Feeding broilers with hemp seed powder (at 20%) resulted in better feed conversion ratio, higher live-weight gain and lower age at slaughter, and lower mortality rate (Khan et al., 2010)
It is possible to partly replace soybean meal by hemp seed meal in broiler diets. Supplementation of hemp seed meal at 1.5-9.0% had no adverse effects on immunological factors. Levels of 1.5-3% might promote B cell differentiation and maturation as well as immunity. Levels of 4.5-7.0% enhanced nitrogen utilization (Ma Li et al., 2007).
Laying hens
With hens fed on 0 to 20% of cold-pressed hemp seed meal, no significant differences were found between feed treatments for egg production, feed consumption, feed efficiency, body weight change or egg quality.
Increasing dietary inclusion of hemp seed meal produced eggs with lower concentrations of palmitic acid and higher concentrations of linoleic and alpha-linolenic acids (Silversides et al., 2005).
Rabbits
Feeding rabbits with hemp oil cake is possible but it has a moderate energy value for rabbits, due to its high fibre content that reduces diet digestibility. It does not have significant organoleptic effects on fresh rabbit meat (Lebas et al., 1988).
