Whether you will actually be once discovered, the eggs legend Jack of all trades? And if Yes: How would this miracle beings, good, the trusted, lots of pressing problems to solve? As always, one imagines, such an all-in-one creature – probably most people would think at the thought of maggots, to plump, a good two inches long, brownish maggots.
And yet have managed just such animals in recent times, to attract a lot of hope and a lot of attention. The larvae of the weapons fly, could help to satisfy the enormous meat hunger a growing world population – both ecologically and economically-friendly than previously possible. It’s not even about the weapons fly lands directly on the human diet. The only recommend a couple of hard-boiled. Even in those Parts of the world, in which regularly for insects to be eaten, these maggots only very rarely on the table.
As almost unbeatable, your Fans prices larvae of the flies as a food for pig, poultry and fish. These animals need a lot of high quality Protein in the feed. So far, especially soy, Corn, and fish meal supply the necessary protein. But huge, as a mono-culture cultivated plantations cause, as well as aquaculture ecological problems.
Possible that the weapons flying a part of your reputation as a problem solver, especially for the clever Marketing of some of the Start-owes ups.
A way out could be to fly the Black Arms. The maggots provide a lot of protein. They are easy to keep and breed, you don’t need a lot of space and are very flexible with regard to your own dining plan. Even kitchen waste, manure and slurry you can live. It sounds perfect: By the weapons destroyed on-the-fly waste, without big claims, makes you farm big and strong.
it is Possible that the weapons flying a part of your reputation as a problem solver, especially for the clever Marketing of some of the Start-owes ups. So far, at least in the EU, Concerns about the feed safety of the use of the larvae, and experts warn against too high expectations. However, Yu-Shiang Wang, and Matan Shelomi of the National Taiwan University, the pilot’s Weapons as fodder for “the insect of choice”, as you write in a review in the magazine “Food”.
Scientifically as Hermetia illucens is known, dates back to the insect, originally from subtropical and tropical regions of the Americas. In the 1920s, turned the weapons on the fly for the first time in Europe. The adult animals are transferred from one to two centimetres tall and is not characterized primarily by what they can respectively do: no mouth, no Biting or Piercing tools – so no possibility of diseases. Adult weapons fly lives only a few days, in which she pairs in which the females up to 500 eggs at a time.
Shortly before pupation they reach their full potential
About four days later, larvae hatch, and for the next two weeks only one objective: to eat. Per day the maggots take up to Twice their own weight to themselves.
The insatiable appetite of the weapons fly larvae can be for the people is extremely useful – for example, when the grubs feed on manure, manure, or vegetable residues, fed. Not only the animals, so as to reduce the waste, but they also make it less attractive for others to fly and reduce its phosphate and nitrogen content. This is beneficial to the environment, when farmers fertilize with manure.
The biggest potential of the animals is shown if the full-fed larvae are nearing pupation. Then you can easily pick-up, drying, milling and animal feed processing. 42 percent Protein, 29 percent fat, plenty of calcium, many minerals and vitamins make the weapons fly to the ideal food source for farm animals. Since insects belong, at least for the chicken anyway for natural dining plan.
As a feed for cattle or chickens not yet
approved the unusual efficiency of the maggots, which is, according to many calculations, on the other insects will be Added. It takes about one and a half kilos of food, a Kilo of larvae to produce dry substance. For beef, the ratio is ten to one particularly unfavorable. In addition, speaks for the weapons fly, that they can easily and on a little area to keep hardly any greenhouse gas emissions and not at all picky in terms of their own feed. Even the waste you may live.
Swiss researchers are testing how the weapons fly are larvae to feed. First results from studies of the ETH Zurich, in cooperation with the research Institute of Organic agriculture show that the whole of the soya could be replaced in the feed for Organic due to the larval material. Other studies with pigs and shrimp show that weapons fly larvae are good properly as soy, Corn or Fish meal replacement in feed.
So it is not surprising that, worldwide, some companies are already on Hermetia illucens, as a feed put. Large breeding facilities, there are especially in South Africa and Canada. Also in several European countries, the larvae grow up in some companies. The Dutch company Protix has taken in June in Bergen op Zoom is one of the largest insect farms in the world with the participation of the St. Gallen company Bühler is in operation. Here the weapons will fly to feed animals bred. The technology of the Swiss company supplied.
If the processed insects, apply as a regular feed, drop, farm animals, the larvae living officially in the category.
And yet, there is the breakthrough of the weapons fly as animal feed in the EU is still in the way. So far, namely, the processed larvae may be fed only to Pets and fish in aquaculture, but not to cattle, pigs and poultry. The prohibition is based on the mad cow disease crisis in the 1990s. At the time, showed how risky it can be to feed livestock with animal Protein. Currently, the EU checks whether processed, the weapons of larvae allowed to fly in the future, end up in pig troughs and chicken coops; the change in the law is likely to be. “An early approval as a feed for poultry and pigs from the EU and Switzerland would be very welcome”, says the ETH researcher Michael Kreuzer.
However, even then, would meet not all of the weapons flying aspirations a blow, but rather, new questions arise. If the processed insects, apply as a regular feed, drop, farm animals, the larvae living officially in the category. Thus, they are subject to strict regulations. Among other things, it is forbidden in the EU, livestock with kitchen, dining and slaughterhouse waste or to the feed slurry.
also Suffer from maggots under mass animal husbandry?
makes Sense, this scheme appears, for example, in view of the hitherto open question of whether the processed maggots is a danger of infection can arise if you have eaten contaminated feed. So it took probably but specially produced insect food to feed the larvae on a large scale. For this purpose, ethical and veterinary medical concerns come in: also Suffer maggots under mass animal husbandry? You feel the pain? Are veterinarians prepared for possible epidemics in a larvae farm?
Wilhelm Windisch from the Department for animal nutrition of the Technical University of Munich, the weapons fly, quite for a possible enrichment in the animal feed market. As a Game-Changer that could displace, for example, soy in animal feed, he does not see the maggots, however. “At present, the Hype around the there’s a cease fly. The idea that you fed the waste to the larvae, and this brings in the food chain, is absurd.” The the contrary, quite rightly, very strict laws for animal Feed.
to sum up, The weapons fly is an amazing insect, but not (yet) Jack of all trades.
