The invention relates to the agricultural industry, in particular to the production of feed for poultry.

A known method of increasing the egg productivity of laying hens [KI 2370099, A23K 1/65, 10/20/2009]. The method includes feeding mixed feed containing wheat, barley, sunflower meal, soybean meal, fish meal, vegetable oil, corn, bran, limestone, monocalcium phosphate, premix, while cadmium sulfate is fed in addition to the main diet during the period from 14 to 16 weeks of life at a dosage of 40 mg per 1 kg of feed. The invention improves the egg productivity of laying hens. The disadvantages of this method are the multicomponent feed and its high cost.

A method for the production of fully expanded expanded feed for rabbits [KI 2416979, A23K 1/00, 04/27/2011] consists in the fact that the grain components of the feed are lupine feed, the feed beans and rapeseed are crushed to a particle size of 0.6-0.9 mm, sieved, mixed with raw grassy cutting, sunflower cake, wheat bran, defluorinated feed phosphate, limestone flour, premix, mix the mixture until smooth, moisten it to 14-16%, keep the mixture for 4 hours in a hopper to equalize moisture throughout the volume, after which the wasp they are processed in a screw expander at a product temperature in front of the annular gap of 393413 K, a screw rotational speed of 5-7 s ^-1 and a pressure in the prematrix zone of the expander of 5-8 MPa, the mixture is prepared the next time the component ratio is selected, wt.%:

wheat bran 8.00; feed lupine 20.0; fodder beans 20.0; sunflower meal 20.0; rape 5.40;

raw grass cutting 22.90; defluorinated feed phosphate 1.20; limestone flour 1.50;

premix 1.00.

The method allows to obtain high quality feed, increased digestibility, balanced in composition. However, this food is intended for herbivore fur animals.

A known method of use in the composition of animal feed and poultry untreated bran. The value of their input for chicken of egg breeds is up to 10% of the diet, and for broiler chickens, turkeys, quails and pheasants they are not recommended to be introduced [Recommendations for feeding poultry, Sergiev Posad: VNIITIP publishing house, 2000, p. 42]. The disadvantage of this method is the limitation of the input of untreated bran, which is associated with a high fiber content in raw materials. The bran itself contains few minerals, and when used in the feed, mineral salts must also be added. In addition, they do not contain beneficial microorganisms that animals need for proper nutrition (good fiber absorption and resistance to pathogens). Bran is a substance rich in vitamins, therefore, they have a high contamination with toxin-forming microorganisms, primarily fungi. Therefore, bran needs additional processing to improve their nutritional properties.

Closest to the claimed invention is a method of producing a feed additive [Ki 2266682, A23K 1/16, 12/27/2005], including pre-treatment of bran with acidic fraction of electroactivated water for 1.5-2.0 hours at a ratio of 1 ton of raw material 10- 20 l of water and mixing bran with a solution containing caustic soda, lime dough and water, with the following ratios of components, wt.%:

bran 95-96; caustic soda 0.2-0.3; lime dough 0.6-0.8; the rest of the water, while the composition is stirred for 20-30 minutes, then incubated for 24-36 hours and mixed with a nutritional supplement containing Glauber's salt and tricalcium phosphate, in the following proportions of components, wt.%:

Glauber's salt 0.2-0.3; tricalcium phosphate 0.5-0.7; the rest, then add a probiotic culture of microorganisms in a concentration of 0.18-0.22% and granulate.

The disadvantages of the method are the multicomponent feed additives and the energy intensity of the process associated with the production of electro-activated water, which increases its cost.

GOST 26826-86 is known. Limestone flour for the production of animal feed for farm animals and birds. This standard applies to limestone flour derived from limestone and complies with the following physicochemical parameters:

the total mass of CaCO ₃ and MDCO ₃ in terms of dry matter is at least 85%, including the mass fraction of Ca at least 32%;

mass fraction of insoluble in HC1 residue not more than 5%;

mass fraction of non-harmful impurities (iron and aluminum oxides) not more than 8%;

mass fraction of toxic impurities not more than 0.158% (including fluorine 0.15%, arsenic 0.006%, lead 0.002%);

mass fraction of metallomagnetic impurities up to and including 2 mm in size no more than 100 mg; mass fraction of moisture not more than 6-10%;

particle size distribution with partial residues on sieves with openings of 1, 3, 5 and 10 mm.

As a result of the use of such limestone flour, daily weight gain of birds and an increase in the safety of the livestock are observed.

The technical solution to the problem is to simplify the method of obtaining and increasing the degree of assimilation of compound feeds intended for agricultural poultry, as well as to increase the weight gain of broilers while maintaining the livestock.

This object is achieved in that in a method for producing a feed additive Mukaltsit for poultry, including processing of nutritious raw materials with water, mixing it with a mineral component and grinding, according to the invention, wheat grains are used as nutritious raw materials, which are treated with artesian water to a moisture content of 4-6 wt.%, mixed with the mineral component - grains of limestone waste fractions 5-63 mm in a ratio of 10-25: 75-90 wt.%, respectively, and carry out joint grinding.

According to the invention, feed feed wheat of the feed grades GOST R 52554-2006 is used for poultry; limestone waste fractions of 5-63 mm with a CaO content of at least 50%, obtained as a result of quarry processing of limestone rock; tap water. In terms of physical and chemical parameters, the used limestone waste mainly corresponds to GOST 26826-86.

The claimed method of producing a feed additive Mukaltsit differs from the prototype in the type of raw material introduced by the mineral component, the implementation of joint grinding of raw materials, providing activation of the surface of the limestone grains, which improves the process of assimilation of compound feed.

These differences allow us to conclude that the claimed technical solution meets the criterion of novelty. These signs are aimed at achieving the task and are not identified when studying this area, therefore, they meet the criterion of inventive step

In the process of co-grinding limestone grains with moistened wheat grains, a lime-flour mixture is formed containing two energetically active phases - crushed limestone grains with free radicals on the exposed surface and dipole water molecules of moistened wheat grains. Due to the electrostatic interaction of dipole water molecules and free radicals of crushed limestone, surface forces arise at the interface between the two phases, which contribute to the formation of an activated film layer of limestone-flour material with a high energy potential on the surface of the limestone. From the point of view of chemical thermodynamics, limestone grains (CaO), which have an excess of free surface energy, form calcium hydroxide Ca (OH) ₂ with water molecules, which cements the mixture components, turning them into limestone-flour mixture crystals. Such activation maximizes homogenization of the lime-flour mixture and increases the degree of assimilation of animal feed with the claimed additive.

A method of obtaining a feed additive Mukaltsit carried out on a laboratory vibration (centrifugal ball) ball mill VM-200M2 with grinding media in the form of steel balls up to 5 mm. The mixer is loaded with limestone waste fractions of 5-63 mm and pre-moistened wheat grains with a moisture degree of 4-6% (GOST 13586.5-93) in a ratio of 10-25: 75-90 wt.%, Respectively, mixed for 20-30 min The resulting raw material mixture is loaded into the grinding drum of the mill. Grinding is carried out at an oscillation frequency of 24 Hz for 0.5-1.0 minutes Within 30 s, the limestone grains are covered with particles of wheat flour, forming a homogeneous powdery limestone-flour mixture with a particle size distribution of 0.063-1.0 mm.

In the invention, quarry limestone wastes were used, which, according to the author’s classification, belong to types I and II of activity: Kazakh with a CaO content of 55.7%, Karadag - CaO 52.3% and Shuvelansky - CaO 48.1% of deposits in the Republic of Azerbaijan.

Examples of a specific embodiment of the method are provided that confirm, but do not limit the invention. To determine the productivity of the proposed feed additives Mukaltsit were selected 4 groups of 50 pieces. two-month-old chickens weighing 300-350 g, which for 5 months received the same diet (table). The experimental groups of chickens (I, II, III) were fed with a feed additive - one of the three compositional options within the claimed limits of the invention (examples 1-3), and the IV group of control chickens received the same feed ration, only without the declared feed additive.

Example 1

The first group of chickens daily received 227 g of feed according to the table and 8 g - 3.5% of the total weight of the feed, feed additive - lime-flour mixture obtained by joint grinding of limestone waste with a CaO content of 55.7%, and wheat grains with a moisture content of 4 % (water from an artesian well), taken at a ratio of 10:90 wt.%, respectively. The birds are healthy, there is no death.

Example 2

The second group of chickens was fed daily according to example 1, with the only difference being that they received 9 g — 4% of the total weight of the feed, and the feed additive — the lime-flour mixture obtained by co-milling lime waste with a CaO content of 52.3% and wheat grains with a moisture content of 5.5% (water from an artesian well), taken at a ratio of 20:80 wt.%, respectively. The birds are healthy, there is no death.

Example 3

The third group of chickens was fed daily according to Example 1, with the only difference being that they received 8 g — 3.5% of the total weight of the feed, the feed additive — the lime-flour mixture obtained by co-milling lime waste with a CaO content of 48.1% and wheat grains with a moisture content of 6% (water from an artesian well) taken at a ratio of 25:75 wt.%, respectively. The birds are healthy, there is no death.

Example 4

The fourth group of chickens received 227 g of feed daily according to the table, while they did not receive the Mukaltsit feed supplement. The birds are healthy, there is no death.

During the experiment, three groups of chickens fed with the Mukaltsit feed additive gained a slaughter weight of 1000-1150 g, and after reaching 4 months, every other day they started to lay eggs of standard size and with a hard shell.

The control group of chickens fed with normal food reached a weight of 900,950 g during the same period, they began to lay eggs only after 7 months.

The obtained good growth productivity of the experimental groups of chickens is explained by the fact that the activated lime-flour mixture promotes better digestion and passes through the intestinal tract completely digested, which was established by microscopic examination of feces of birds. In the control group of chickens, undigested feed components, mainly vegetable, are observed. The invention helps to increase live weight by 17%, egg production by 15%.
