Description

The invention relates to fodder production, and in particular to the composition of fodder flour for feeding agricultural and non-productive animals obtained on the basis of green tea and waste from the production of rice grain, in particular rice husk (also called husk), as well as methods for its production.

It is known that whole or ground rice husk, which is a source of renewable natural silicon dioxide, can be included in the diet of animals. Moreover, it is characterized by low digestibility.

Along with this, the positive role of such polymers, including indigestible and indigestible, which are called dietary fibers, enterosorbents, plant sorbents, amorphous, including biogenic silicon dioxide, has recently become apparent.

Known feed mineral additive for poultry (1. Pat. RF №2129806, CL A23K 1/175, publ. 05/10/1999), containing amorphous silica. This additive is a siliceous mineral - carbonate-silicate rock containing calcium carbonate, zeolite, amorphous silica (4-20% wt.) And clay mineral bentonite. Calcium carbonate is easily absorbed by the birds, and zeolite, amorphous silica and bentonite contribute to the elimination of toxic nitrate ions, lead, cadmium from the body of a bird.

A known method of obtaining a feed additive for animals containing amorphous silica. This method involves mixing and grinding a component containing amorphous silica with components not containing amorphous silica. Mix and grind the components, wt%: zeolite - 87 ÷ 89, sulfur-containing component - 10 ÷ 11 and an additional flavoring element - skimmed milk powder - 1 ÷ 2. Silica-zeolite ore of the Volgograd deposit containing minerals: clinoptilolite, types of silica (opal, cristobalite, tridemite) and calcite are used as zeolite. Zeolite has the following chemical composition, wt.%: Silicon dioxide 69 ÷ 81, aluminum oxide 4 ÷ 8, calcium oxide 4 ÷ 18, potassium oxide 1.5 ÷ 2.5, sodium oxide 0.6 ÷ 1.5, titanium oxide 9 ÷ 10, water 9 ÷ 10. The sorption capacity of this zeolite for copper is 4.7 mg / l, for cadmium - 3.1 mg / l. As a sulfur-containing component, granular elemental sulfur is used - the waste of oil product desulphurization plants. These components are mixed and ground to a particle size of not more than 0.25 mm (2. Pat. RF No. 2293472, class A23K 1/175, publ. 02.20.2007).

A disadvantage of the known technical solutions is the use of mineral sources of silicon dioxide, which are not renewable natural raw materials. In addition, silicon from inorganic silicates is not as physiologically active as silicon from plant sources (3. M.P. Kolesnikov. Forms of silicon in plants // Advances in Biological Chemistry. - 2001. - T.41. - P.306).

The closest technical solution adopted for the prototype of the proposed technical solution is a method for producing a hydrolyzate from rice husks and other cereals, in which hydrolysis of plant materials — rice husks — is used to obtain fodder dry powder products (4. Pat. RF No. 2262242, class A23J 1/12, published on October 20, 2005). Since rice husk consists mainly of cellulose and hemicellulose, with cellulose being hydrolyzed by acids and hemicellulose by alkalis, both acidic and alkaline hydrolysis are used. Thus, this method of obtaining a hydrolyzate from plant materials — rice husks — includes hydrolysis of plant materials with acid, followed by neutralization with sodium hydroxide, purification and drying of the resulting hydrolyzate. The acid used is hydrochloric acid. After neutralization with sodium hydroxide, the obtained intermediate is homogenized, then hydrolysis is carried out with sodium hydroxide with a concentration of 2 ÷ 10% at a temperature of 100 ÷ 120 ° C for 2 ÷ 6 hours and neutralization with hydrochloric acid at a volume ratio of raw materials to chemical reagents (1: 4) ÷ (1: 6), after which the resulting hydrolyzate is dried.

The disadvantages of the known technical solutions are the processing of rice husk in the liquid phase, the complexity and multi-stage preparation method (the presence of stages of acid hydrolysis, neutralization, homogenization, alkaline hydrolysis, neutralization, drying).

The problem solved by the claimed technical solution is to obtain feed flour for farm and non-productive animals from rice husk and green tea, which has increased water solubility and bioavailability of amorphous silicon dioxide and increased antioxidant activity, using a new, technologically simple method.

The problem is solved thanks to the claimed composition of feed flour from rice husk and green tea for agricultural and non-productive animals, including,% wt .: source of chelating agents - 5-20, hydrolyzing agent - 0.5-5 and air-dried rice husk containing water up to 17% wt., - the rest.

Preferably, the feed meal contains green tea as a source of chelating agents.

The content of green tea in feed flour is preferably 5-10% wt.

Preferably, as a hydrolyzing agent, the feed meal contains, together or separately, an enzyme preparation having cellulolytic activity and an enzyme preparation having proteolytic activity.

Preferably, the total content of enzyme preparations is 0.5 ÷ 3% wt.

Preferably, as an enzyme preparation having cellulolytic activity, the feed meal contains CelloLux-F with an activity of 2000 units / g.

Preferably, as an enzyme preparation having cellulolytic activity, the feed meal contains Cloververidin GZx with an activity of 2000 units / g.

Preferably, as an enzyme preparation having proteolytic activity, the feed meal contains Protosubtilin GZx with an activity of 70 units / g.

The inventive feed flour is obtained by mechanochemical processing of air-dried rice husk, mixed with hydrolyzing agents, as well as mixed with a source of chelating agents, in an activator mill, that is, in a simpler and more economical way.

In this case, water-soluble chelate complexes of silicon are formed (5. Shapolova EG, Korolev KG, Politov AA, Lomovsky OI Use of complexes of polyphenolic tea compounds for mechanochemical solubilization of silicon // New advances in chemistry and chemical technology of plant raw materials: materials of the IV All-Russian Conference. April 21-23, 2009: in 2 books / Edited by N.G. Bazarnova, V.I. Markin. - Barnaul: Publishing house Alt.un-ta , 2009. - Book 2. - P.87-89).

Under the air-dry rice husk understand rice husk with a water content of up to 17 wt.% (6. TU 8-22-11-78 "Rice husk" with Amendment No. 1 and Amendment No. 2).

The inventive feed flour can be used to balance the feed on silicon, in particular in areas with a lack of silicon or an excess of aluminum in the feed (to neutralize the toxic effects of aluminum), as well as to prevent oxidative stress, since it has antioxidant properties.

The problem is also solved thanks to the claimed method of obtaining feed flour from rice husk and green tea, including hydrolysis of rice husk and obtaining a dry powder product, in which, according to the invention, an air-dried rice husk containing water up to 17% by weight is mixed with a source of chelating agents and a hydrolyzing agent in the ratio of (75 ÷ 100): (5 ÷ 20) :( 0.5 ÷ 5) by weight, respectively, and the resulting mixture is subjected to mechanochemical treatment in an activator mill, while using an activator mill zuyut flow vibratory centrifugal ball, ellipse centrifugal and centrifugal roller mill to ensure acceleration of milling bodies of 80-250 m / s ² and the residence time of the treated mixture of husk, chelating agents and source hydrolyzing agent in the treatment zone 0.5 ÷ 2.5 m.

The indicated ratios of the concentrations of the components of the mechanically processed mixture and the parameters of the mechanochemical processing (acceleration of grinding media, residence time of the processed mixture in the zone of influence of grinding media, the number and geometric characteristics of grinding media loaded into the mechanochemical mill-activator) depend on the kinetic characteristics of the mechanochemical process.

The increase in the content of the source of chelating agents, for example green tea, in the inventive feed meal of more than 20% wt. leads to a significant decrease in the content of rice husk - a source of amorphous silicon dioxide.

Since rice husk contains both cellulose and proteins, simultaneous enzymatic hydrolysis of both components is more effective than hydrolysis of the components separately, as a result of which the simultaneous use of a mixture of enzyme preparations with cellulolytic and proteolytic activity leads to an increase in the effect.

The use of a mixture of enzyme preparations in the amount of less than 0.5% wt. due to the lack of enzyme preparations, it has a weak effect. The use of enzyme preparations in total in an amount of more than 3% wt. leads to a decrease in the economic efficiency of the use of feed flour.

The use of each of the enzyme preparations individually in an amount of more than 5% wt. leads to a significant decrease in the economic efficiency of the use of the composition.

The parameters of the mechanochemical treatment are determined by the following circumstances. When using the acceleration of grinding media less than 80 m / s ² there is a decrease in the efficiency of mixing and activation. The use of acceleration of more than 250 m / s ² does not lead to a further increase in processing efficiency, and also causes the inactivation of enzyme preparations.

A residence time of less than 0.5 min in the processing zone does not allow to obtain a high-quality target product. A residence time of more than 2.5 minutes does not lead to a further increase in the processing efficiency, and also causes the inactivation of enzyme preparations.

The inventive method is as follows.

Example 1

Air-dried rice husk (antioxidant activity = 0.9 g quercetin per g husk) is pre-crushed to a particle size of 1-3 mm. A source of chelating agents and a hydrolyzing agent are not added. The obtained intermediate is subjected to mechanochemical treatment in a flow-through ball vibrocentrifugal mill of the VTsM-50 type (ICTTM SB RAS, Novosibirsk) with acceleration of grinding media 80 m / s ² and a residence time of 2.5 minutes in the treatment zone. The target product is subjected to analysis as well as storage testing. The product is a fine powder (flour). The target product can be used as a feed in the production of animal feed and in animal feed.

The properties of the target product were compared with the properties of the control sample. A control sample is a semi-product after preliminary grinding to 1-3 mm, but which has not undergone further mechanochemical processing. The specific surface of the samples was determined by thermal desorption of argon. The content of water-soluble silicon compounds (in terms of silicon) in the test suspensions (1 g of sample in 100 ml of a buffer solution with pH 7), which were exposed for 240 minutes at room temperature, was determined spectrophotometrically. Antioxidant activity (AOA) was determined by a certified method (7. Method for measuring the antioxidant content in drinks and food products, biologically active additives, extracts of medicinal plants by the amperometric method. Certificate No. 31-07. JSC NPO Himavtomatika, M., 2007) in terms of standard quercetin. The analysis was carried out similarly to the analysis of the tea leaf on the TsvetYauza-01AA device (OAO NPO Khimavtomatika, Moscow) included in the State Register (8. Certificate of approval of the type of measuring instruments No. 21449 dated 08/31/2005. Registered in the State Register under No. 20706-05) .

From the data obtained it follows that as a result of the mechanochemical treatment of air-dried rice husk in the respective test samples, the specific surface area increases from 0.5 m ² / g to 1.1 m ² / g, the content of water-soluble silicon compounds (in terms of silicon) increases from 4 μg / ml to 6 μg / ml, and AOA increases from 0.9 to 2.8 mg of quercetin per g of flour.

It was also found that after two months of storage of the sample of the target product, its AOA slightly decreases from 2.8 to 2.5 mg of quercetin per g of flour.

Using optical microscopy, it was shown in vitro that in the presence of particles of the target product, pathogenic Salmonella enterica bacteria are fixed on the surface of these particles, which entails the removal of pathogenic bacteria from the body along with these particles. Thus, the target product exhibits enterosorption properties.

Antioxidant activity was determined according to the certified method (7) in terms of the standard quercetin. The analysis was carried out similarly to the analysis of the tea leaf on the TsvetYauza-01AA device (OAO NPO Himavtomatika, Moscow), included in the State Register (8).

The properties of the target product were compared with the properties of the control sample. A control sample is a semi-product after preliminary grinding to 1 ÷ 3 mm, but which has not undergone further mechanochemical processing. The specific surface of the samples was determined by thermal desorption of argon. The content of water-soluble silicon compounds (in terms of silicon) in the test suspensions (1 g of sample in 100 ml of a buffer solution with pH 7), which were exposed for 240 minutes at room temperature, was determined spectrophotometrically.

In 2009, the target product was tested at the SIBNIPTIZh during the feeding of poultry (quail). It was found that the addition of this target product in an amount of 300 g per 1 ton of feed, balanced according to VNITIP standards, leads to an increase in the average daily increase in live weight of young poultry (quails) by 7%, feed costs per 1 g of growth are reduced by 10%, egg production by a layer is increased by 10%, feed costs per unit of output are reduced by 17%, the additional profit for the production of 1000 eggs is 40 rubles.

In addition, in 2009, the target product was tested at the SibNIPTIZh GNU when fattening geese in the meat direction of productivity. The target product was added to the basic diet, compiled according to zootechnical standards, in an amount of 1%. It was established that the target product favorably affects the body as a whole, stimulates the metabolism and normalizes lipid metabolism, and also improves the use of feed nutrients. The gross growth of experimental geese (55 days old) was 16% higher than in animals from the control group. Compared to the control, the experimental geese affected 16% less feed per growth. Hematological studies have shown that the target product has a beneficial effect on mineral metabolism. In addition, the experienced geese had a more stable immunity. Samples of the average sample of muscle tissue and liver had no obvious changes, which confirms the safety of feeding the target product. Feeding the target product allowed to reduce feed costs by 1 g of gain in live weight and to get additional profit for 1 head of 41 rubles.

Using the invention will allow using a new, technologically simple way to obtain feed flour from rice husk and green tea in the form of a finely ground powder with increased antioxidant activity, high content - and hence high bioavailability - of water-soluble silicon compounds obtained from amorphous silica of rice husk. Such flour can be used to balance the feed on silicon, in particular in areas with a lack of silicon or an excess of aluminum in the feed (to neutralize the toxic effects of aluminum), as well as to prevent oxidative stress.

The socially beneficial effect of using the invention is to prevent oxidative stress, as well as more complete assimilation of silicon compounds contained in the original rice husk, feeding animals with all the positive consequences that follow from this, i.e. in a more complete and rational use of a valuable, renewable plant product - rice husk.

An additional positive effect achieved by the invention is the manifestation of the inventive feed flour properties of enterosorbent. This effect is explained by the presence of cellulose and biogenic silicon dioxide in the rice husk, which exhibit enterosorption properties as a result of mechanochemical treatment.
