Box 7024, 750 07, Uppsala, Sweden. Abstract Two experiments were carried out in the research farm of An Giang University.
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
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
Earthworms are recognised as an effective and environmentally sound method of increasing the rate Earthworm production systems involving waste management are evolving and are in the growth phase where emphasis is upon marketing, inoculum and vermicast. As the industry matures there will be a need to change the marketing emphasis from “the worm as an inoculum” to “the worm as a value-added marketable product”. Very large quantities of worm products will be available if production systems are designed and managed appropriately. The integration of waste utilisation with the production of high q
Earthworm Powder, a new product begin to emerge in the market and may help to increase the life quality of all animals: the Earthworm Flour. Searches of Food Technology Institute (Ital) of São Paulo, Federal University of São Paulo, Federal University of Brasília, Federal University of Paraná, Agronomic Laboratory S/C (LAGRO), Agricultural Nuclear Energy Center, were important factor for the success of the journey. Searches concluded earthworm flour like a product with high essential amino acids concentrations and high liquid protein utilization (biologic value). The Earthworm Flour has been

However, practical pharmacological studies have not been performed except on lumbrofebrin as an antifebrile (1). In 1983, we reported that very strong and novel fibrinolytic enzymes could be extracted from the
Utilization of earthworms (Perionyx excavatus) as a protein source for growing fingerling marble goby (Oxyeleotris marmoratus) and tra catfish (Pangasius hypophthalmus) Nguyen Huu Yen Nhi Faculty of Agricultural and Natural resource, An Giang University, Long Xuyen City, Vietnam email@example.com Literature review Biological characteristics and feeding behavior of two fish species There are many reports on the effects of various animal wastes on growth and reproduction of earthworms. According to Chaudhuri and Gautam Bhattacharjee (2002), biomass production and reproduction of the
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
