Earthworms – An animal feed alternative

05-05-2017 Anphu Earthworm Co., Ltd - Solution for organic agriculture
Using insects as an alternative to the conventional animal feed has been researched for quite some time now, ranging from flies to insect larvea, this new alternative could be the answer to the ever increasing price of animal feed. Now earthworms are being bred as an alternative feed source, and the waste is being seen as a rich fertilzer. A win-win some would say.

Most farmers apply fertilizers and all kinds of manure such as human waste and animal urine on their farms to improve production. They also mulch as an agronomic practice to improve on productivity. Those engaged in dairy, poultry and fish farming use feed made out of varying mixtures that include bran, husks, stover and other matter.
However, this time around, they are being introduced to a technology of using earthworms to serve the same purpose. Scientists at Makerere University Agricultural Institute Kabonyolo (MUARIK) started rearing the earthworms under a programme known as management of manure for vermin compost, where they mix maize bran with food remains and cow dung with water as a bulk material for the worms to feed on.
Mr Charles Azizi Dara, a foreman in the machinery section at MUARIK, says the team started the rearing earthworms about a year ago. It was an initiative to address the challenge faced by poultry and fish farmers in purchasing feed at high price as well as to address the use of organic manure by farmers growing crops.
Earthworms take one month to mature but their life span is two years. They do not lay eggs but cocoons. These begin hatching once the cocoons are mature causing rapid multiplication of its generation.
Poultry and fish farmers can give their chicken and fish either live worms or they can harvest them and mix with other feeds such as milled fish, maize bran and husks for the same feeding process.
“Farmers can venture into earthworm rearing as a side business because the process is not labour-intensive and besides, farmers who grow crops and rear either chicken or fish can gain in both ways because the waste matter of these worms can be used as manure, which will result into high yields of the crops,” Dara said.
Nankinga suggests instead of farmers coming to the institute to purchase the worms as parent stock, they should become “outgrowers” to supply fellow farmers. This is because the worms can be harvested in swampy and moist places and as long as farmers have the interest in breeding them, they can also search for parent stock.

    Earthworms: Live Foods

    by Dave Ball President of the Southern Colorado Aquarium Society Aquarticles Summer is just around the corner and I’ve got a real bad case of Spring fever. It seems to get worse every year. This is the time of the year when cheap fish food becomes available. What I mean by “cheap” is free food. All you have to provide is time and the containers. Grasshoppers, crickets, and earthworms are starting to show up in the yards, parks, and fields. We’ll get to the first at a later date, the good old earthworm is the subject of the day. How many of you want a fish food that is good for your fish? I

    Aquaculture with Earthworm

    Two studies were conducted at the experimental farm of An Giang University, Viet Nam. The first study on the growth of earthworms (Perionyx excavates) was a 2*2 factorial experiment with 4 replicates, in which the treatments were: source of manure (cow or buffalo) and supplementation with water hyacinth at 25% of the weight of manure (DM basis) or none. Adding chopped water hyacinth to buffalo or cattle manure led to a decrease in worm numbers and in productivity per kg DM and crude protein of added substrate. Relative growth in numbers and in weight of the worms was similar on manure

    Earthworm-Water Hyacinth Project

    From 2012, Anphu earthworm Co.,Ltd has launched campaign to help poor farmer along river to take water-hyacinth to raise earthworm. By collecting water-hyacinth from river then put into pp pack, after 10 days, bring home and keep in dry and lean-to. Then put vermiculture (earthworm) into pack about 5kg. after 40 days the worm eat all food, this time we can harvest worm and casting. The result, after 6 months apply, each family has over 40 bins, every month they collect 30kg of worm to feed fish, chicken, duck, pig.. otherwise, the casting they got then can fertilize plant to give very

    How To Harvest Worm?

    When to Harvest Generally, a worm bin will have produced a significant amount of good vermicompost at between two and three months along in the process. If you wait even longer, like 4-6 months, you'll have more finished looking vermicompost (it will look more like soil and have more plant-ready nutrients in it). Tip - Try harvesting early one time, then letting it go for much longer the next time, so that you can see the difference in finished product. Harvesting Methods There are several common ways to separate worms from the vermicompost in your bin. Dump And Sort It's just

    Formulating fish feed using earthworms as a protein source

    Formulated feeds are complete feeds which supply all the nutrients necessary for optimal growth and health of the fish in culture practices. In many areas of the world protein sources are scarce and for formulating aquafeeds earthworms as a protein source might provide an alternative to common used raw materials.Earthworm: Good nutrition in an animal production system is essential to economically produce a healthy, high quality product. Nutrition is critical because it represents 40% to 50% of operational and production cost. Fish nutrition has advanced dramatically in recent

    Partial replacement of fish meal by earthworm meal

    Full Length Research Paper Partial replacement of fish meal by earthworm meal (Libyodrilus violaceus) in diets for African catfish, Clarias gariepinus Fish meal is the most common source of protein for aqua feeds. However, the cost of fish meal is on the rise, because of its competing use as feed ingredient by other animals (livestock, ruminants etc.). It is therefore necessary to find alternatives to fish meal in the preparation of animal diets.Various workers have attempted to use other locally available cheap protein sources (e.g. plant protein, agricultural by- products, fishery

    What earthworm can not eat?

    If you’re looking for another reason to eat fresh and eat healthy, this may be it! Worms can eat pretty much any organic matter that was once living, which encompasses a lot of healthy food such as fruits, vegetables and grains! That’s a pretty good incentive to buy fruits and vegetables more often. Not only is it great for your health, it provides food for your small wiggly friends as well. One small problem some people run into is not having the appropriate food for their worms and trying to feed them food scraps on the non-approved list! If your eating habits include more processed food th
