Study Notes
Insect Feed in Livestock Production
- Interest in insects, particularly larvae, as feed for livestock is rapidly increasing.
- Black soldier fly (Hermetia illucens) is a promising insect species for feed conversion from food waste and manure into high-quality protein.
- Native to Central and Latin America, H. illucens is now established in most tropical regions worldwide.
Nutritional Profile of H. illucens
- Protein and lipid content of defatted H. illucens meal (HIM) ranges significantly:
- 47.2% protein and 11.8% lipid (Kroeckel et al., 2012)
- 51.8% protein and 14.8% lipid (Cullere et al., 2016)
- Full-fat HIM contains 36.2% protein and 18.0% lipid (Barroso et al., 2014).
Diets and Experimental Results
- Experimental diets included one commercial and one experimental formulation.
- Replacement of fishmeal with insect meal showed no adverse effects on growth, feed conversion, or product quality.
- Reduced protein utilization efficiency in fish fed with HIM may impact overall production over a full production cycle.
Aquaculture and Protein Sources
- Aquaculture contributes significantly to global fish supply, with about 50% of food fish being produced through aquaculture as of 2006.
- Global finfish production rose by 90% from 2004 to 2014, driving demand for high-quality, protein-rich feed ingredients.
- Organic aquaculture requires that all feed ingredients be organically or sustainably certified, limiting available resources and affecting prices.
Technical Findings
- H. illucens larvae were fed chicken feed until the second larval stage, demonstrating a controlled feeding process.
- Digestible Energy (DE) values and the digestible protein to digestible energy (DP:DE) ratio aid in evaluating feed efficiency, indicating potential variations in performance based on dietary composition.
