The nutritional value of insects depends on the stage of their life ( metamorphic stage ) , their habitat and their food. However, it is widely accepted that :
Insects provide protein and high-quality nutrients . Ils sont particulièrement importants en tant que compléments alimentaires pour les enfants sous alimentés, car la plupart des espèces d'insectes sont riches en acides gras (comparables au poisson). They are also rich in fiber and trace elements such as copper , iron, magnesium, manganese , phosphorus , selenium, and zinc.
Insects have a low risk of transmission of zoonotic diseases ( diseases transmitted from animals to humans) as H1N1 ( bird flu) and BSE ( mad cow).
The feed conversion ratio of insects is extremely effective. On average , 2 kg of feed are needed to produce 1 kg of insects, while cattle require 8 kg of feed to produce 1 kg of meat . Insects have a high conversion rate because they are cold- blooded animals. feed conversion rate ( the amount of food required to produce an increase in weight of 1 kg) varies considerably depending on the species and production techniques used.
The production of greenhouse gases by most insects is likely to be lower than that of conventional livestock (except termites ) . For example , pigs produce between 10 to 100 times more greenhouse gas per kilogram compared with the breeding of locusts.
Insects use much less water than conventional livestock ( pigs, cattle , ...).
The insects from breeding requires the utilization of considerably less area of farmland that conventional livestock such as cattle .
The collection and breeding of insects can offer to important strategies for diversification of livelihoods for the poor, but also offer additional revenue opportunities for farmers at all levels, including even for large agro -industrial enterprises in all in the world.
The insects can be collected directly and easily to the natural state. Expenses or investments required for the harvest and to obtain basic breeding material are minimal. The " know-how " for the breeding of insects is simple.
Insects can be harvested in the natural state, grown, processed and sold by the poorest of society, such as women and the landless in urban and rural areas. These activities can directly improve diets and provide cash income through the sale of surplus production as an street food .
Breeding of industrial form of insects can provide business opportunities in developed economies in transition and developing especially in mainlines fish and chickens. Insects can be processed for food and feed relatively simply . Some species can be eaten whole . Insects can also be converted into pulp or ground into flour and proteins can be extracted.
Breeding insects not required the use / possession of land or significant start-up investment , such as for cattle .
In addition , as it can do as well in urban area has very low production cost , a lot of people s weak economic means can initiate and participate in the production of proteins (a base of insects) for their own subsistence and / or to supply the agri-food sectors , including use as feed in fish farming and chickens.
A great advantage in the breeding of insects is that the insects can feed on organic waste, such as food and human waste, compost and manure and can turn that into high-quality protein that can be used for power livestock or fish farming .
And their livestock do not require the utilization of seeds such as soy, corn or wheat widely used in breeding of chickens, pigs or cattle, and thus puts available for their direct human consumption instead of see -oriented animal husbandry animals.
