Description

The invention relates to feed production, animal husbandry and veterinary medicine, namely to feed additives and methods for feeding them to farm animals in order to prevent stress factors.

Known feed additive "Zeoton" for the prevention of mycotoxicosis of birds and the method of feeding it. The feed additive includes natural zeolite and sodium thiosulfate (see RF patent No. 2262863 dated 10.27.2005 A23K 1/16, 1/175), has detoxifying properties.

Known feed additive containing natural zeolite - sahaptin (TU 9318-001-10185443-97), which includes macro - and micronutrients, vital for the animal organism, and the method of its application. The additive has adsorption, ion exchange, detoxification and prolonging properties and is used for the prevention of mycotoxicosis (Akhmetov F.G., Ivanov A.V., Tremasov M.Ya. Prevention of mycotoxicosis in animals. // Veterinary medicine. - No. 2. 2001. - C 47-50).

However, these feed additives do not contain anti-stress substances.

Known adaptogens used in animal husbandry and poultry farming to prevent stress loads in the production of meat, eggs. The most widespread use of various pharmacological agents (antipsychotics, tranquilizers and sedatives (aminosine, chlorpromazine, reserpine, phenozepam, seduxen, etc.). In most cases, they are used by subcutaneous, intramuscular or oral administration with water, which allows to partially reduce the negative the impact of stress factors on animals and birds, and reduce the loss of live and slaughter mass.

However, it should be said that despite the positive effect of the use of tranquilizers, antipsychotics and sedatives, there are a number of significant drawbacks, namely:

- short duration of action (3-4 hours after administration and the effect decreases dramatically);

- high cost, difficulties with administration (creation of additional stresses during fixation).

It should be noted that these drugs have been used to prevent transport stress.

Eleutheracoccus preparations and Rhodiola rosea extract, which have the same properties, are also used as adaptogens. Both drugs are prescribed for the correction of technological stresses for 2-3 weeks (See Pharmacology. - Kolos, 1997. - P. 382).

The closest solution adopted for the prototype is the synthetic adaptogen Aurole. The formula of the active substance is empirical C ₈ H ₁₀ O ₂ with the chemical name 2- (4-hydroxyphenyl) ethyl alcohol (see patent No. 2063395 dated July 18, 1996, bull. No. 19), which has a pronounced stimulating effect, immunomodulating and cardioprotective activity, anti-carcinogenic and anti-inflammatory properties.

However, it should be pointed out that, despite the positive effect, the use of Aurool has a significant drawback: the specified adaptogen Aurool is used exclusively by feeding animals and birds.

The objective of the present invention is to expand the arsenal of feed additives for birds with adaptogenic properties.

The technical problem is solved in that the feed additive for the prevention of stress factors in birds, including the stress protector Aurole, according to the invention additionally contains natural zeolite in the following proportions, wt. %:

natural zeolite - 99.04,

synthetic Aurole (Tyrosol-C) - 0.06.

The essence of the invention also lies in the fact that in the method of feeding a feed additive for the prevention of stress factors in birds, including the introduction of a feed additive in the main diet, according to the invention, natural zeolite 99.04 and synthetic Aurool (Tyrosol-C) 0 are used as a feed additive , 06 (wt.%), Feed the additive in an amount of 5-6% by weight of the main diet of the bird, for 7-14 days.

A method of preparing a feed additive.

The proposed feed additive is prepared as follows: the feed additive is prepared by irrigation of a natural zeolite - sahaptin (fraction 1-3 mm for poultry) with an aqueous solution of Aurool (Tirazol-S) with the following ratios of components, wt. %:

natural zeolite - 99.04%,

Aurol (Tirazol-S) - 0.06% ± 0.0012.

To do this, Aurol (Tirazol-S) 0.06 g is taken, which is dissolved in 100 ml of distilled water, this solution is introduced (irrigated) in 99.06 to 100 g of zeolite-sahaptin, then it is thoroughly mixed in mixers and dried on shelves in a gentle 30-40 ° C to constant humidity. As a result of irrigation and drying, Aurol (Tirazol-S) is adsorbed on zeolite-sahaptin. The resulting feed additive can be introduced to the main diet.

The finished feed additive is packaged in plastic bags from 3 to 20 kg, labeled and delivered to the consumer, where it is mixed with the main poultry feed.

The feed additive is named “Ceaur”.

The invention is illustrated by the following examples.

Example 1. The effect of introducing various doses of the feed additive “Ceaur” to the main diet in the presence of a stress factor was studied. To conduct research on the principle of analogues, 6 groups of chickens of 10 goals were formed, growing them according to the traditional technology of keeping and feeding. All groups were stressed.

The 1st control group received 100% of the main diet (RR), the 2nd 100% RR + 3% Tseaur, the 3rd 100% RR + 4% Tseaur, the 4th 100% RR + 5% " Ceaur ”, 5th 100% OR + 6%“ Ceaur ”, 6th 100% OR + 8%“ Ceaur ”. (Table 1).

The various doses studied (3, 4, 5, 6, 8%) of the Zeaur feed additive had a positive but not the same effect both on reducing losses under the influence of stress factors and on the subsequent increase in live weight. The most optimal (appropriate) dose is 5-6% of the introduction of Ceaura into the main diet for such technological stresses as changing the conditions of feeding and feeding, when changing the feeding phase, forming (picking) and moving from room to room, preparation for egg laying.

Example 2

The effect of the Zeaur feed concentrate on chickens of the egg direction Rhodailand Cross Isa Brown, under stresses on growth, development in different age periods was studied.

To conduct research on the basis of analogues, five groups of chickens were formed with 10 animals each. Chickens were grown according to traditional technology in RSC cells, in the vivarium of the Institute of GNU IEVSiDV of the Russian Agricultural Academy, with adjustable feeding and microclimate parameters.

The conditions for feeding the poultry corresponded to the standards accepted for rooster rooster eggs of the Rhodeyland Cross Isa Brown. From 21 to 65 days of age, chickens were kept in small cells, then from 65 to 105 days of age they were kept in RPS cells. The chickens received high-quality, full-grain, granulated compound feed of the Biopro company.

Chickens of group 1 served as a pure control, and chickens of the second group served as control for all experimental groups. Chickens of 2-5 groups were periodically stressed (did not set food, did not set water, subjected chicks to noise effects, widely used light stress factors).

Experience outline

Group 1 chickens were given 100% of the main diet (RR) and were not exposed to stress factors. Group 2 chickens received 100% OR and were stressed. The third group received 100% OR + 5% zeolite-sahaptin and were subjected to stress, the fourth group received 100% OR + an aqueous solution of Aurole (Tirazol-S) at a rate of 1 mg / kg body weight and were stressed, the fifth group received 100% OR + 5% “Ceaur” and was stressed.

We found that in the 2nd control group, the average daily gain in live weight was 10% lower than in the 1st group, which was contained without stress.

In the 3rd experimental group, the average daily gain was higher by 9.22% in relation to the 2nd control group, and in the 4th group - by 11.0% in relation to the 2nd control group. In the fifth troupe - by 14.6%, where the diet included Zeaur feed additive. (Table 2)

An important indicator is the mass of gutted carcasses. In control group 2, this indicator was 66.7% of the live weight of 1401 (971.4 g of carcass weight), in the 5th experimental group - 70% of the live weight of 1624.2 g (1077.8 carcass weight), and the fourth experimental group - 69.5% of the live weight of 1606.2 (1026.8 g of carcass weight), in the 3rd group - 67.9% of the live weight of 1547.8 (996.3 g of carcass weight). In the experimental groups there is a tendency to increase the yield of meat.

The results of the experiment show that losses from stress factors without the use of adaptogens and feed additives amounted to 10%.

The data obtained showed that “Ceaur” is effective under stress and more effective than the components introduced separately, used separately. Blood biochemical parameters among the groups did not have significant differences. Feeding the bird before and after stress “Ceaura” significantly reduced their stress state, which was confirmed in life manifestations (less depressed and more mobile compared to peers from the control group.

Example 3

In the third experiment, on 31 day old chickens, we studied the effect of the feed additive on the prevention of feed stress (mycotoxicosis) in chickens from 31 days to 95 days of age. Over the 63 days of the experiment, the increase in live weight fluctuated in groups.

Experience outline

1 control - 100% OR, 2 experimental - 100% OR + 6% fungus culture containing 616 mg / kg T-2 toxin, 3 experimental - 100% OR - 6% fungus culture + 5% “Ceaur”.

From the data obtained it follows that the growth in the 2nd experimental group (without feed additives) was significantly lower by 8%, while in the 3rd experimental group with the addition of “Ceaur” the increase was 2.5% higher relative to 1 control group (table 3).

For 63 days of experiment, from chickens, where 5% of Ceaur was added, and T-2 contaminated with mycotoxin was added to the feed, an additional gain in live weight was obtained in relation to the 1st control group and 9.3 g and to the 2nd control group 136 g. The average live weight of the chicken before slaughter in the 2nd group was less by 126 g compared to the 1st group, and a strong feed stress factor influenced the weight loss. The increase in live weight of chickens with feed stress factor in the 3rd group was influenced by the feed additive “Ceaur”. The bilirubin indices in the 2nd group were greater than in the 1st group. Indicators of calcium, phosphorus, sodium, magnesium, potassium and cholesterol in the chickens of the 3rd group compared with the 1st group had insignificant fluctuations and did not have significant differences. Studies have shown the effectiveness of “Tseaur” in feed stress, expressed in gaining a gain in live weight of chickens and the safety of their health.

Example 4

Production tests of the Zeaur feed concentrate of Ust-Abakan Poultry LLC to study the influence of biologically active additives and economic and economic indicators of the organism of Rodonit cross birds by introducing 5% of the feed concentrate by weight of the feed into the diet (Table 4).

Studies have shown that the course introduction of feed concentrates in the experimental groups increases the safety of young birds up to 2.00%, compared with the control group. The increase in mass of chickens in the first experimental group is higher than in the control group by 16.90%, in the second by 20.63%.

The use of concentrates before the transfer of young poultry to the adult livestock workshop ensured the process of early egg laying.

At the age of 180 days, the productivity of laying hens in the first experimental group was 10.60%, in the second experimental group it was 15.80% higher than in the control group, where the egg production was 55.50%.

The safety in the experimental groups was 99.51%; 99.73%, respectively; in the control group 99.40%. The increase in adult bird mass in the experimental groups is higher than in the control group by 17.00%; 22.54%, respectively.

At the age of 270 days, the egg-laying rate of laying hens is significantly higher than in the control group by 25.30%; 25.60% respectively. In the control group, egg production was 72.50%. The safety of adult birds in this period in the first experimental group was 99.51%, in the second experimental group 99.50%, in the control group 98.40%. The increase in adult bird mass in the experimental groups is 15.22% more than in the control group; 18.24% respectively.

At the age of 345 days, egg production of an adult bird in the first experimental group was 98.10%, safety 99.02%, weight gain -1690.00 g. In the second experimental group, egg production was 98.30%, safety - 99.28%, growth mass - 1780.00 g.

The influence of “Tseaur”, introduced into the diet at the rate of 5-6% of the feed weight in the main diet of laying hens, improves the nutritional properties and marketability of eggs, which is reflected in an increase of 4.48 g relative to the control group; relative to the mass of protein per 0.40 g; yolk for 16.90 g; shell mass by 10.40 g and shell thickness by 0.01 mm.

When applying “Ceaur”, a positive effect on the average daily gain in live weight of chickens from 7 to 28 days was established, it was more than the control by 19.22%. At the end of the experiment, it was 18.32 g more, which is higher than the control group by 2.54 g or 16.09%.

As a result of studies of the Zeaur feed concentrate on laying hens, it can be noted that early course application stimulates an increase in the safety and weight gain of the poultry, and also provides an increase in the egg laying intensity of laying hens in the experimental groups by 15.18% compared to indicators in birds in the control group.

Cost-effectiveness of using “Tseaur” in feeding laying hens: 2.8-3.6 rubles of profit fell per 1 ruble of expenses. The profitability level of egg production was 3.6% higher in the experimental group compared to the control group.

As a result of studies, it was found that the declared feed additive “Ceaur” has a positive effect on the clinical condition of chickens, helps to increase the average daily gain in live weight of chickens, increases egg production, nutritional properties and commercial quality of eggs, which indicates its effectiveness.
