Description

The invention relates to agriculture, in particular to the fodder production from manure of agricultural animals and bird droppings.

The aim of the invention is to accelerate the process.

EXAMPLE 1 For pigs, litterless litter of broiler chickens that did not contain feathers was loaded into the batch mixer C-12A, into which calcium oxide was added in an amount of 2% of the dry matter content. With the help of anti-rotating rotor workers, the manure underwent continuous chaotic movement in the closed space of the mixer for 1.5 hours. Due to the strongly alkaline reaction of calcium hydroxide under conditions of active movement, the hydrophobic structure of the intestinal microflora membranes in the manure proceeded. At the same time, due to the alkaline reaction, the molecular weight of natural polymers decreased in undigested nutrients: proteins, EBV, fats and fiber. In addition, calcium hydroxide, when interacting with the anions of carbonic acid of the litter, formed calcium bicarbonate, which masked the smell of skatole, indole and hydrogen sulfide, which are formed during the decomposition of the intestinal microflora of cystine and methionine.

After 1.5 hours of the preliminary period of deodorization, ammonium carbonate was added to the mixer C-12A at the rate of 3 dry matter content in the treated litter. Stirring was carried out for 1 h at the closed position of the loading door. Due to the fact that the ammonium carbonate molecule is a derivative of weak carbonic acid (Ki 4 Ka) in the average strength of hydro- .1 N1

it produces carbonic acid calcium carbonate with lime limestone, which strengthened the effect of deodorization, ammonium hydroxide molecules, dgsa in large amounts of atomic ammonia, completely killed 5 and microorganisms, and due to the alkaline ammonium hydroxide, the destruction of a high molecular weight molecule followed the alkaline reaction. , fats, BEV and fiber. Due to the occurrence of these reactions, the litter completely wiped off the unpleasant smell and disinfected.

At the end of the joint processes of decontamination, deodorization and nitriding, the manure was discharged with a discharge device of a mixture of 15 bodies and conveyed to the scraper conveyor-40.0С conveyor. Simultaneous bukker continuously fed cutting of sweet hay of 2-3 cm in length, obtained on the IGK-GOAL feed measuring device. 20 Hay of white clover was taken in a mass ratio of 1: 1.5 with a dry substance of deodorized and at the same time nitrated litter. In the box of the scraper conveyor, a two-layer 25 continuous conveyor flow of plant mass was formed, which entered the receiving bin of the unit for the preparation of ABM-3,0 vitamin flour. -. .

From the specified receiving hopper 30, a mixture of crushed sweet hay and manure was fed to the working rotating drum of the ABM-3.0 aggregate. In the process of heat and mass transfer with a gaseous coolant, volatile 35 substances and moisture from the litter mixture evaporated. At the same time, the processes of thermochemical processing of the nutrients of the litter and hay, as well as the intensive evaporation of natural coumarin, contained in the ground stock hay cutting, proceeded at the same time. Due to the evaporation of coumarin, the dried manure inside the rotating drum aromatized. Thermally treated flavored dung-senna mixture 45 was fed to a KDM-2.0 hammermill where it was ground into small particles with the subsequent production of heat-treated dung grain.

In the control, the litter litter of 50 broiler chickens was processed by a known method.

The feed obtained with the experiment and control was used as an additional additive to the main daily ration. In the experimental and control groups, 50 animals were set. When uboe animals of the experimental group, it was established that their sternum liver did not have the smell of droppings, in the control group the sternum and liver in b pigs had the smell of droppings. At the same time, the total duration of the manure processing process was A h against 60 h by a known method, the average daily gain of pigs was 628 ± 8.16 g versus 557 ± 7.2 g. Loss of dry matter was 0.68% against 8.35%, loss of raw protein accounted for 1.53% versus 8.85%.

Example 2. For sheep and gobies, in a similar pattern, litter chicken manure was deodorized with finely divided chalk, injected in an amount of 2% of dry matter, and nitrated with ammonium bicarbonate, injected in an amount of 4% of dry matter. Further, during heat treatment in the AVM-3.0 aggregate, deodorized and nitrated manure were taken in a 1: 1 ratio with an developed clover cutting in terms of dry matter. After dehydration in the rotating drum of the aggregate, heat-treated cutting was obtained, into which 5% of common salt was injected during briquetting. A scientific and experimental experiment was carried out according to a sectoral methodology; 50 animals were identified in the experimental and control groups of animals.

During slaughter, bychkoz and rams of the experimental group, the livers and carcasses did not have the smell of a litter; from the control group of bulls, the smell of droppings was detected in 7 heads of bulls and 5 heads of baranchik. The total processing time of the litter was 3.5 hours versus 60 hours by a known method, the average daily gains for bulls and barblings were 1178 ± 19.3 and 193 + 6.1, respectively, against 837 ± 11.0 and 146 ± 4.3 g, losses crude protein was 4.81% versus 23.81%.

EXAMPLE 3. For lactating cows, experiments were carried out with dried duck droppings. In the C-12A mixer, it was mixed with the addition of 5% AUS carbonate. The mixing time was 20 minutes. Next, the manure was loaded into a horizontal trench; the height of each manure was 20–25 cm. A layer of moist hay cutting of a white clover with a moisture content of 34.4% was formed on top of each river. Hay and duck manure treated in a carbon-salt mixer were taken in a mass ratio of 1: 1.25, calculated on the dry matter.

After biological three-week maturation of the litter in a mixture with wet sweet hay, a decontaminated

coumarin-flavored prten-mix. .

In the control, duck droppings were processed according to a known method.

The feed obtained in the experiment and control was used in the daily ration of lactating cows as an additional source of energy protein feed. In the experimental and control groups was set to 50 naked. The average daily milk yield from the cows of the experimental group in terms of 4% 1% was 13.96 0 ± ± 0.10 l versus 14.79 ± 0.23 l in the control, while the milk from the cows of the experimental group receiving the proposed dung the mixture had no smell of litter, milk from 11 heads of the control group receiving the known mixture had the smell of litter.

The loss of dry matter was 2.15% versus 14.64% by a known method, the loss of crude protein was 3.12% versus 16.57%. The total processing time in the mixer and bookmarks in the storage in terms of every 10 tons was 2 hours compared to 60 hours in the known method.
