The US post-2018 Farm Invoice hemp growth helped create an issue the business remains to be wrestling with: an excessive amount of flower and too few patrons.
Throughout that point, CBD-rich hemp biomass reportedly bought for $30–$40 per pound, whereas tons of of hundreds of acres had been licensed on the business’s peak. However the economics modified rapidly. Costs fell, acreage contracted, and huge volumes of hemp biomass started shedding their worth after harvest and processing.
Seven years down the road, the issue has not disappeared. USDA information present that U.S. floral hemp manufacturing reached 33.2 million kilos in 2025, a 60% improve from 2024. Extra manufacturing means extra materials competing for patrons, significantly in a market the place demand for cannabinoid-rich flower and biomass stays restricted.
That raises an more and more vital query: what if a few of that extra hemp may turn out to be animal feed?
The thought isn’t as far-fetched because it sounds. Hemp processing generates a number of doubtlessly helpful byproducts, together with hempseed meal, hempseed cake, leaves and spent biomass.
The chance might be important since greater than 60% of US hemp has traditionally been grown for CBD manufacturing, creating substantial portions of processing byproducts. As a substitute of sending a few of this materials to compost or landfill, processors may doubtlessly flip it into one other income stream.
Why hemp for Animal Feed Makes Sense on Paper
The dietary case for hemp as animal feed is genuinely robust, explaining why researchers have spent years on it. Hemp seed cake as an example, comprises about 34% crude protein with roughly 12.7% residual lipids and carries a positive omega-3 fatty acid profile. Scholarly critiques present it has higher rumen bypass protein than rapeseed meal, making it a possible protected protein supply for high-producing dairy cows. Hemp leaf is a secondary feed fraction with about 13% crude protein and excessive fiber, appropriate for ruminants.
Early feeding trials strengthened the case. In lactating dairy cows, diets containing as much as 143 g of hempseed cake per kg of dry matter elevated energy-corrected milk yield; inclusion above that stage diluted milk fats and protein percentages.
A examine from the College of Manitoba reported hemp meal may exchange canola meal at as much as 10.2% of food regimen dry matter with no detrimental results on consumption, rumen fermentation, digestibility, or blood metabolites making it “a high-quality and secure protein complement.”
Whereas this seems to be nice, the deal breaker has at all times been THC and CBD switch into animal merchandise reminiscent of milk, meat, and eggs. On the alarming aspect, a 2022 examine in Nature Meals discovered that feeding hemp silage to dairy cows produced measurable THC, CBD, and associated cannabinoids in milk, and estimated that worst-case THC consumption from that milk may exceed the conservative acute reference dose.
However the newer US work factors in the direction of withdrawal intervals as a sensible answer. Researchers from Oregon State College fed 9 Jersey cows a food regimen with 13% spent hemp biomass for 28 days. THC did seem in milk throughout feeding although lower than 1% of ingested cannabinoids transferred nevertheless it grew to become undetectable roughly 12 days after the biomass was eliminated, and the crew concluded a two-week withdrawal window would remove client danger.
In a parallel beef trial, steers fed spent hemp biomass confirmed no antagonistic behaviour or weight-gain results; cannabinoids concentrated in fats tissue, cleared from all tissues after 33 days of withdrawal besides hint CBD in adipose tissue.
This leads us to a scientific consensus that hemp byproducts are probably secure for many ruminant species, with manageable residue danger offered low-cannabinoid materials (seed fractions) or outlined withdrawal home windows (whole-plant materials) are used.
Science could set up whether or not hemp has dietary worth, however regulators decide if that worth can turn out to be a market. In 2025, the regulatory image started to vary. AAFCO formally acknowledged mechanically extracted hemp seed meal as an animal feed ingredient for laying hens, permitting inclusion at as much as 20% of the food regimen, offered the ingredient comprises not more than 20 ppm whole CBD and a pair of ppm whole THC.
The event is critical, however it isn’t a blanket approval for hemp in animal feed. The FDA has not authorized CBD or cannabinoid-rich hemp substances for animal meals, citing unresolved security considerations. Nevertheless, the regulatory image started to shift in 2025: FDA solicited new security and utilization information on hemp-derived merchandise in animals.
For an business looking for makes use of for surplus hemp, that distinction issues. Hemp seed meal now has an outlined regulatory pathway into animal agriculture. The larger query is whether or not different hemp byproducts, significantly the massive volumes generated by cannabinoid extraction, can meet the identical security and regulatory necessities.

Structural frictions to adopting hemp as animal feed
There are three foremost structural frictions that retains the federal course of sluggish;
- CBD is handled as a drug: As a result of CBD is the lively ingredient within the FDA-approved epilepsy drug Epidiolex and has been the topic of considerable medical investigations, FDA considers the addition of CBD to animal meals prohibited whereas AAFCO’s 2025 approval is proscribed to mechanically extracted hemp seed meal, with strict CBD and THC limits, and doesn’t lengthen to CBD-rich plant materials or spent cannabinoid-extraction biomass.
- Approval is ingredient– and – use particular: Bringing a brand new animal-feed ingredient to market can require a considerable security file and a proper FDA evaluate, with the petition submitted and supported by the sponsoring firm or group. The approval applies to the particular ingredient, supposed use, and situations evaluated, somewhat than to a whole class of hemp-derived supplies.
- Analysis is pricey: Within the U.S., animals utilized in research of hemp feed substances usually can’t enter the meals chain until researchers acquire a Meals Use Authorization. With out one, animals uncovered to investigational hemp byproducts could must be euthanized and their stays disposed of somewhat than getting into the meals provide, including considerably to the price of producing the protection information wanted for regulatory approval.
A number of states have moved forward of the federal authorities. Alaska, Tennessee, New Jersey, Ohio, West Virginia, Montana, Kentucky, Oklahoma, Texas, and Virginia have adopted insurance policies permitting sure hemp-derived substances in animal feed, though the permitted substances, species, and situations fluctuate significantly.
Kentucky, for instance, permits hemp seed meal and hemp seed oil underneath its state feed guidelines, whereas Oklahoma permits hemp grain and its derivatives for livestock feed. Texas has issued steerage permitting hemp seed meal for horses and chickens, and Montana permits sure hemp and hemp-derived substances in feed for pets, specialty pets, and horses whereas excluding CBD merchandise.
The image is equally fragmented internationally. Canada has cultivated hemp since 1998, however CFIA’s present steerage states that hemp merchandise will not be usually authorized as livestock feed substances, with every proposed hemp ingredient requiring separate evaluation. The European Union permits qualifying low-THC hemp varieties, usually capped at 0.3% THC for cultivation underneath the Frequent Agricultural Coverage, whereas hempseed-derived feed merchandise can enter the EU feed market underneath present guidelines, though nationwide necessities could differ.
Australia presently doesn’t allow industrial hemp as inventory feed, largely due to considerations about cannabinoid residues getting into the human meals chain, however that place is now underneath lively evaluate. In July 2026, an Australian Senate committee really useful that the federal government look at regulatory adjustments affecting the hemp business, following proof and submissions on the potential use of hemp in animal feed. New Zealand has additionally permitted low-THC hemp seed as human meals, however this doesn’t quantity to a normal authorization for hemp as animal feed.
Conclusion
Whereas animal feed may turn out to be a part of hemp’s reply to the oversupply downside, it’s unlikely to be a easy outlet for the business’s extra biomass. The a lot bigger query is whether or not different hemp byproducts, significantly materials left after cannabinoid extraction, can generate the protection, residue, dietary, and toxicological information wanted for approval. That can require greater than proving that animals can eat hemp.
Researchers and regulators want to ascertain how completely different hemp substances have an effect on animal well being, whether or not cannabinoids switch into meat, milk, or eggs, what inclusion ranges are applicable, and the way these merchandise could be examined persistently. On the identical time, feed producers might want to decide whether or not hemp can compete economically with established protein, fiber, and oil sources.
The chance, then, will not be about discovering one market able to absorbing all of hemp’s surplus. It could be about growing a extra round hemp business the place completely different components of the plant are directed towards their highest-value makes use of. If science, regulation, and economics ultimately align, animal feed may flip a few of right this moment’s low-value hemp byproducts right into a industrial useful resource. Till then, it stays a promising chance somewhat than an escape route from the oversupply entice.
