Growing Maggot for Animal Feed: My Little Experiment
#1
With the high price of animal feed, growing maggots is beginning to make sense. Maggots come from flies. When flies lay eggs, the eggs pass through several stages before they turn into flies. One of the stages is the maggot stage.
You can use the maggot to feed fish, chickens and other animals.  I’m targeting fish and chickens but I’ll be starting with chickens.

Growing The Maggots
To grow maggot, you need cheap inputs like manure, kitchen waste and sawdust or rice hull. I mixed rice hull with manure (my layers’ droppings) in a bowl (let’s call this growing bowl) and added just enough water to make it moist but not wet. I then mix thoroughly and placed some kitchen waste on this mixture to attract a lot of flies. You can use soup, fruits or anything that will attract a lot of flies. I used my dog’s leftover garri balls mixed with soup.
   
   

Note: The growing bowl you used should have holes in the bottom so that excess water can go out. These holes must be small so that some maggots won’t escape.

After the flies have finished laying their eggs. cover the bowl with something and place under a shaded area. Protect it from ants, lizards, chickens etc. I used chicken wire to cover them and finally cover with zinc. The chicken wire will prevent lizards and the zinc will stop chickens. I placed the growing bowls on a raised platform. The little kerosene I sprayed on the platform will stop ants. In few hours time you’ll see some small maggots. Leave them for 5 days before you harvest.

Harvesting
Spread net over a bowl (harvesting bowl).
   

Place the maggot-filled substrate on the net. Spread it thinly so that they can’t hide under. Fear of light will make them to force themselves through the tiny holes in the net.
   
   

Mine were big and some could not pass through the net. This was because I harvested when they were 8 days old. This makes harvesting very tedious because I have to pick many by hand. Next time I’ll harvest when they are smaller, say 5 days old. Note that the older the maggots, the less nutrient they’ll contain – and the less digestible they’ll become. Young maggots, though smaller, are more nutritious and more digestible.
To prevent the maggots from climbing the walls of the harvesting bowl, dust it with ash or rice hull dust. I used rice hull dust.

Maggots like hiding away from light, so it will be good if you place something in the harvesting bowl where they can hide under. I used rice hull but later regretted it because I later have to separate the maggots from it. Next time I’ll be using a plastic cover, making provision for access roads they’ll use to crawl under the plastic.

If you leave them beyond 10 days, they’ll turn into flies and fly away.

Harvest was bountiful. It makes sense to do this large scale.


To process, I poured very hot water on them. This will kill every germs in it and makes it more digestible. I left if in the hot water for a while before draining.

I drain out excess water.
   

Then I spray it on a net to dry.

The best way to dry maggot is on a suspended net.

I’m looking forward to do this in a larger scale. Some people travel all the way to Songhai farm, Benin Republic to learn this among other things. Now I’ve tried it and saw the harvest, I strongly believed it will be profitable. Fly is free and everywhere. 

Just thinking – In a war situation, isn’t this a very good source of super cheap protein?

I just leave the growing bowl open the first day. Just cover it with a chicken wire to protect from chickens.

Update: I finally dry the maggots under the sun. It took 2 days to dry very well.
   

The dry maggots weigh 109 grams.

I've not tried feeding them to broilers though. But if you can balance the nutrients you'll get good result.
