Abstract

The present invention relates to human excrement base feed with high nutrition content, which is prepared by taking fresh human excrement as main raw material through the technologies of deodorization, sterilization, dehydration, fermentation, etc. The human excrement base feed which is prepared from 10 to 100% of human excrement has the characteristics of no odor, pathogenic bacteria eliminating, high nutrient content, good feeding palatability and easy absorption and digestion. The human excrement base feed which has the advantages of simple preparation method, low cost and convenient transportation is superior to the existing compound feed. The present invention relieves the conflict that human beings strive grain with fowl, changes waste into valuable materials and reduces the environmental pollution from human excrement.

Description

A kind ofly contain the odorless high-efficiency feed that human faecal mass is a raw material

The present invention relates to animal feed, being specially with the human faecal mass is the feed of the high nutrient content be processed into of raw material.

For satisfying the human needs growing to domestic animal, fowl, birds, beasts and eggs and fish food, developed the kinds of artificial mixed feed, but raw materials used based on grain, exist serious " people and animals strive grain " contradiction.Developed resourceful producting stalk fodder again for this reason; As the saccharification straw, ammonification straw etc. are in the hope of reaching the use that reduces grain.But this class feed is because crude protein, crude fat content is low and little carbohydrate, and the content of material height that cellulose, lignin etc. are difficult to digest and assimilate, and the palatability of feeding is poor, feed intake is few, absorbs that conversion ratio is low, feeding effect is undesirable, is difficult to apply.The food that the mankind eat, big portion is a high protein, higher fatty acid, the nutriment of high-loads such as multivitamin, trace element; But the actual nutriment that is absorbed by the body is less, overwhelming majority nutritional labeling is all discharged in ight soil, so ight soil of people, it is a kind of available huge resource, as to utilize its as fertilizer sources be a kind of good fertilizer, only fails to be fully utilized because of factors such as its transportation make its cost be higher than chemical fertilizer.Just measure according to argol the people: wherein * crude protein 27～42%, * * crude fat 8～14%, NFE 28～36%, * * * crude fibre 5～9%, and contain amino acid, multivitamin, trace element etc., its nutritional labeling is extremely abundant; But contain cause of disease, virus and harmful microorganism in the human faecal mass, have shortcomings such as stink, can not be directly used in feed, only take the special technique measure, overcome above-mentioned shortcoming, just may utilize it as feed.

Purpose of the present invention utilizes people's ight soil to be raw material, adopts feasible deodorizing, the method and the processing technology of sterilization, and human faecal mass is processed into odorless, no germ, nontoxic, and feed agreeable to the taste, easily be absorbed the feed of the high nutrient content of digestion.

For making the loss that is not destroyed of effective nutritional labeling in the human faecal mass, it is primary raw material that the present invention selects bright human faecal mass for use, makes the high nutrient content base feed of odorless, anosis toadstool through processing technologys such as deodorizing, sterilization and dehydration, fermentations.Because human fecal material's difference, wherein contained nutritional labeling has difference; And the difference of the object of feeding such as pig, ox, sheep, chicken (chick, fryer, laying hen), fish and shrimp etc., nutrition to feed requires also different, for this reason, through deodorizing, sterilization treatment, the human faecal mass basal feed that processes such as dehydration, fermentation become, need its main nutrition is analyzed,, can directly be used to feed as feed with it according to the needs of feeding; Also can allocate other an amount of required composition into, make feed and feed.Therefore, high-efficiency feed of the present invention is to contain 10～100% human faecal mass base feed.Can be pure human faecal mass base feed, the feed of processing that also can be human faecal mass base feed with grain or grain leftover bits and pieces, edible oil leftover bits and pieces, meat, fish and bone, the grass that can feed, leaf, straw, ammonification straw, saccharification straw, food leftover bits and pieces, beverage leftover bits and pieces, poultry, brid guano cooperate.Handle and to make its odorless, anosis bacterium evil owing to carry out deodoring and disinfecting through ferrous sulfate, magnesium sulfide, active carbon and HTHP, again through technologies such as dehydration, fermentations, make human faecal mass become proper moisture content with feed agreeable to the taste, the high-efficiency feed that is easy to assimilate.Its concrete making step is as follows:

(1) in bright human faecal mass, add by weight 0.05～0.1% sulfurous acid iron, 0.03～0.05% magnesium sulfate and 5～10% active carbon, stir down, 110 ℃～120 ℃ of temperature, pressure 1-2kg/cm ²Handled 5～10 minutes, and then, carried out decompression dehydration, extremely dehydration back volume of material is 45～50% of a former material volume, and is cooled to room temperature (18 ℃～20 ℃);

(2) add to drop into the brewex's grains of raw material gross weight 5～10% or vinasse, 15～20% hay powder, in mixer, stir be mixed even;

(3) fermentation is after 2-3 days in fermentation vat, and through 70 ℃～80 ℃ oven dry, the control water content is less than 12%;

(4) measure main nutrient composition: crude protein, crude fat;

(5) prepare burden as required drying, pulverizing, granulation made.

The human faecal mass of described aquatic foods is often referred to the ight soil of discharging in 24 hours, but the difference of southern and northern area and Various Seasonal temperature, but the control of root actual conditions can surpass 24 hours as northern area or winter, and south or summer can suitably shorten the time, are as the criterion with no tart flavour; The food-grade reagent that described ferrous sulfate, magnesium sulfate are buied for the chemical industry shop; Described upright stone tablet vinasse are upright stone tablet wine factory leftover bits and pieces, and vinasse refer to produce the leftover bits and pieces of liquor or grape wine factory, and described hay powder refers to can be used for feeding and be ground into 40～60 purpose hays, dried leaf powder etc.

Of the present invention be the feed free from extraneous odour that is processed into of primary raw material with the human faecal mass, have that wine flavour has the nutrient content height, the good palatability of feeding, the characteristics that are easy to assimilate, be better than existing mixed feed (table 1); Because with aboundresources, cheap human faecal mass is primary raw material, easy to process simple, not only alleviated the contradiction of " people and animals strive grain ", and cost is low, is convenient to transport.Reduced the pollution of human faecal mass to environment simultaneously, the ight soil of the more public place Portaloo of crowd is handled in the big city certainly of being particularly useful for being situated between, and can " turn waste into wealth ".Because its combination property is better than mixed feed, again can be according to the difference object of feeding, directly feed with human faecal mass base feed, also can replenish other an amount of composition and be mixed with all kinds of feed products, therefore wide application can be widely used in feeding of tame fowl poultry kind such as pig, ox, sheep, chicken, duck and fish and shrimp.
