Method for preparing chicken feed taking fly maggot as raw material

Abstract

The invention discloses a method for preparing chicken feed taking fly maggots as raw materials. The method comprises the following steps: A, preparing bean straw powder, namely, piling straws into a pond, inserting a nozzle by the depth of 25-30cm into the straw pile, and subsequently filling ammonia water along the nozzle, tightly wrapping the straw pile by using a plastic membrane so as to prevent air leakage, after 5-7 days, opening the membrane, crushing the straw into 60 mesh powder, and screening for later use, wherein 12kg of ammonia water with the concentration in mass percentage of 20-25% is filled into every 100kg of straws; B, preparing a fly maggot feed; C, adding corn flour, bean flour, spirulina flour, wheat bran, calcium powder, dried blood, polypeptide, hydroxymethyl cellulose and modified starch into the powder prepared in the step A, mixing according to a mass ratio of 1:5, uniformly stirring, and keeping the water content to be 45-55%; and D, mixing the mixtures prepared in the steps A, B and C, preparing into granular materials of which the diameters are 2-3mm by using a granulator, and drying, thereby obtaining the chicken feed taking fly maggots as raw materials. The feed is simple in method, the chicken feed prepared by using the method is simple in proportioning and convenient to take, the total content of cereals is controlled to be 45-55%, and thus the cost of the feed is greatly lowered.

Description

[0001] technical field [0002] The invention relates to the technical field of feed, in particular to a method for manufacturing chicken feed using fly maggots as raw materials. [0003] Background technique [0004] China is a large animal husbandry country. In the process of animal husbandry, especially large-scale farms, due to the need to reduce costs, they basically do not purchase pre-configured full-price feed, but configure their own. In the process of formulating feed, grain raw materials account for a large proportion, such as corn content of at least 50%, and the rest such as soybean flour, wheat bran, spirulina powder, etc. are grain raw materials. In the feed in the prior art, the content of grain raw materials usually accounts for about 80% of the mass ratio, and in view of the higher price of grain raw materials on the market, such a large proportion of proportioning causes an increase in production costs, and the proportion of grain raw materials is high. ...

Problems solved by technology

In the feed in the prior art, the content of grain raw materials usually accounts for about 80% of the mass ratio, and in view of the higher price of grain raw materials on the market, such a large proportion of proportioning causes an increase in production costs, and the proportion of grain raw materials is high. Indigestion of poultry and livestock also causes problems in the digestive system of poultry and livestock, so it is often necessary to add fermentation bacteria to assist digestion
