This project will provide preliminary data on the fate of THC in sheep fed whole plant hemp. It will also provide preliminary data on nutritional value and palatability.
The project objectives are to;
1) Analyse and understand nutritional value of whole-plant hemp as a potential green feed for ruminants in summer;
2) Establish a dosage response relationship of THC excretion from sheep and accumulation in meat.
3) Measure performance, feed conversion efficiency, digestibility and meat quality of sheep fed diets containing
hemp at varying levels of THC;
