Charles Sturt College scientists are enjoying a key function in new analysis to grasp the alternatives to make use of industrial hemp as a feed supply for sheep and cattle.
The challenge is funded by AgriFutures Australia and led by the Division of Main Industries and Regional Improvement, Western Australia (DPIRD) with Charles Sturt and ChemCentre. It goals to supply new data to tell regulators and contribute in the direction of an trade Code of Observe.
Industrial hemp is an rising crop that reveals nice potential, however additional investigation is required round its potential for grazing.
“Hemp is a fast-growing, water environment friendly annual crop that may be grown in various Australian states underneath strict licence circumstances for seeds and fibre,” Charles Sturt Faculty of Agricultural, Environmental and Veterinary Sciences affiliate professor, Gaye Krebs, mentioned.
“A pilot examine carried out at Charles Sturt College in Wagga Wagga recognized potential for the crop for use in livestock feed. But it surely additionally highlighted the necessity for extra data, notably round residues of tetrahydrocannabinol (THC) in meat.”
Industrial hemp incorporates low ranges of this psychoactive compound and underneath present rules, no detectible THC ought to enter the meals market via animal merchandise.
Globally, there’s been little or no analysis concerning the breakdown of THC in sheep and cattle and the way lengthy it stays in tissue after animals have been fed industrial hemp.
“Our analysis goals to fill in a few of these data gaps to supply the data wanted by regulators to permit the crop to be grazed by animals destined for the meals chain,” DPIRD challenge lead Dr Bronwyn Blake mentioned.
The analysis is supported by ChemCentre NATA licensed evaluation, to finish these important regulatory and compliance research that improve an understanding of commercial hemp feed use by ruminants.
“Hemp seed will be consumed by folks, as a result of analysis has enabled a most THC and cannabinoid degree to be set and we need to present the info to permit the identical for meat product,” ChemCentre meals scientist Kenneth Dods mentioned.
The analysis will construct on the findings of the 2020 pilot examine, which highlighted the potential worth of commercial hemp as a feed supply.
“On this new examine, we are going to examine the feed worth and potential for residues in meat from feeding inexperienced plant materials, versus the crop residue or stubble that was used within the pilot examine,” Krebs mentioned.
“We can even start pharmacokinetics research to get an understanding of how lengthy it might take the THC residues to be cleared from the meat and the animal. The pilot examine in contrast feeding pellets the place the roughage element was both from industrial hemp or straw.
“It confirmed there was no distinction in feed consumption between the teams, however the sheep fed the hemp pellets had improved nutrient utilisation.”
