Abstract

Two experiments were carried out in the research farm of An Giang University. The first experiment was a study on the growth performance of Marble goby and Tra catfish fed diets of trash fish and rice field prawns replaced (on an iso-nitrogenous basis) with 0, 25, 50, 75 and 100% of frozen earthworms (Perionyx excavates).

The weight gains of Marble goby and Tra catfish, and the survival rate in the Marble Goby, decreased markedly with curvilinear trends as the proportion of frozen earthworms in the diet was increased (Experiment 1). The Tra catfish appeared to adapt better than the Marble goby to the frozen worms.  The second experiment, which was designed to test the hypothesis  that the poor growth rates with frozen earthworms was due to the low palatability of the earthworms after being frozen, confirmed the negative effects of this method of conservation. Growth rates were 4 and 2 times greater for Marble goby and Tra catfish, respectively,  when they were fed fresh rather than frozen earthworms.  Survival rate was 100% on the fresh earthworm diet.

    Earthworm,Cow,Grass – A big cycle!

    My sister in the cow permaculture world, uses earthworms as a handy source of protein for her cow.  I'm unlikely to follow in her footsteps since the infrastructure demands are quite high, but I wanted to share her process in case some of you are keen to give it a shot. She has a big ruber farm, in Cuchi of which she has sunk worm bins into the soil (surrounded by cinderblocks to keep the worms in place.)  He puts big sheets of plastic along the ruber line, on top she cover its to protest the ruber leaves and rain.  The bins are full of cow manure from her cow farm along wit

    Including Earthworm in Organic Poultry Diets

    Introduction It is common for free-range chickens to consume earthworms. Earthworms are very efficient at converting plant and animal wastes into biomass that can be used as a feed ingredient in animal production: a ton of animal wastes will produce about 100 kg of worms (Edwards, 1985). Earthworms are a good quality protein for use in animal feeds, but the practical use of earthworm meal is influenced by economics. Technology is available for large-scale production of earthworms, but separating the earthworms from the organic wastes in which they are growing is labor intensive, thus

    Earthworm And Maggot Meals As A Potential Fish Meal Replacement

    Earthworm And Maggot Meals As A Potential Fish Meal Replacement Three meals were formulated from the earthworm (Endrilus eugineae) and maggot (Musca domestica) and fish (Engraulis encrosicolus). These meals were evaluated as a potential replacement for fishmeal. This is because fishmeal could be very expensive at times. The three meals were used in feeding the catfish (Heterobranchus isopterus) fry for 30 days. Read

    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
