Animal feed and Veterinary products control (DLD)

( กองควบคุมอาหารและยาสัตว์ กรมปศุสัตว์ )

– Use as raw material or in complete diet

– Data need > Declare to Government > Meeting > Approve by Government• Farming and processing

• Laboratory analysis: Proximate analysis & Amino acid & Fatty acid profiles

• Experimental test (in vitro & in vivo)

4. Regulation to use insects as raw material or diets

5. Conclusion

- Insects have potential to be feed

- Some challenge and questions

- Regulation (Thailand and other countries)

- Productive efficiency (Cost)

- Digestibility, Meat quality and Other consequences after usage

- Consumer perception

- Others
