For replacing fish meal in poultry feed, i got this:
BSF maggots can replace fishmeal much more easily than soybean meal in poultry feed.
Here’s why:
Nutritional comparison (dry matter basis)
Fishmeal: 55–65% protein, good amino acid profile (esp. lysine, methionine), low fat (about 8–12%).
BSFL (maggots): 35–45% protein, high fat (25–35%), rich in lauric acid (which also helps fight gut pathogens).
Replacement potential
Studies show BSFL can replace 50–100% of fishmeal in poultry diets without reducing growth or egg production.
Some trials even found improved feed conversion ratio and immunity when BSFL replaced fishmeal.
Things to watch out for
Fat content – BSFL is much fattier than fishmeal, so the diet’s energy level must be balanced. Sometimes defatted BSFL meal is used for higher protein, lower fat.
Calcium/phosphorus balance – BSFL is rich in calcium (especially if grown on certain substrates). The mineral mix may need adjusting.
Processing – Drying and grinding maggots properly is important to avoid rancidity or microbial contamination.
