Initiative 1: Benefits of Spent (Processed) Marc as an animal/aquaculture feed additive

Spent (Processed) Marc preservativescompleted
Trial various preservatives to preserve Spent (Processed) Marc and/or related products.

Enzymes to enhance feed value of Spent (Processed) Marccompleted
Trial various enzymes to improve Spent (Processed) Marc digestibility for ruminants.

Marc Analysiscompleted
Explore suitability to use Near Infra-red for marc analysis.

Dookie Dairy Trialcompleted
Proven viability of VitiFeed (Crimped Marc) as a diary ration ingredient.

Acti-Meal as Abalone feedcompleted
Conduct commercial trial with Southern Ocean Marine Cultures to verify the benefits of feeding Abalones with Acti-Meal.

Aquaculture – Finfishcompleted
Collaboration with SARDI – indicated that Acti-Meal was potentially a viable feed additive for omnivores but not carnivores.

Value add marc with Mealwormcurrent
Collaboration with GoTerra – Demonstrate the viability of mealworm production using Spent (Processed) Marc and/or related products as Spent (Processed) Marc volume reduction, nutrition improvement and value add tools.
Production of commercial quantities of processed mealworms for sale in human and animal markets.

Finfish fed with Mealworm Protein - pending
This project will be a continuation from the ‘Value add marc with Mealworm’ project. The objective will be to investigate the viability of protein derived from mealworms fed substrate blends, composed predominantly of dried processed Grape Marc as fishmeal replacer for finfish.

Optimising Acti-Meal for Abalonecompleted
Tarac engaged James Cook University to conduct a research study optimising Acti-Meal ratio for Abalone. This project focuses on formula optimisation, growth-response trials and heat stress analysis.

Mealworm for Prawn Feed - pending
This project will be a continuation from the ‘Value add marc with Mealworm’ project.  The objective will be to investigate viability of protein derived from mealworms fed substrate blends composed predominantly of dried processed Grape Marc as fishmeal replacer for prawn feed.
