Description

The invention relates to the feeding of poultry, namely broiler chickens.

It is known from the prior art that the antioxidant ethoxyquin (Santokhin) is used: 1) as a highly effective stabilizer of fats and vitamins in feed of farm animals; 2) as a prophylactic and therapeutic agent against diseases of animals and birds, encephalomalacia, exudative diathesis, muscle dystrophy. (Instruction for the use of ethoxyquin (Santokhin) in animal husbandry and in the production of grass meal. Department of Veterinary Medicine, Ministry of Agriculture of Russia No. 13-5-2 / 1144. TU 6-02-1288-84 IZM, 1-5, 07.09.2004).

There is also a known method of feeding chickens, taken as a prototype and comprising introducing ethoxyquine into the main diet in order to increase the gain in live weight of broiler chickens (Middleton TF et al., Poult. Sci. 2001 Aug; 80 (8): 1154-63, The effect ofethoxyquin on the quality of ground poultry mortality carcasses preserved by lactic acid fermentation and phosphoric acid stabilization).

According to the prior art, antioxidants intensify the functional activity of the protective systems of animals and birds and increase productivity. The world is constantly searching for new, more effective antioxidants to increase the growth rate of animals and birds.

The new domestic preparation, dihydroethoxyquin, is a hydrogenated derivative of the antioxidant ethoxyquin widely used in the production of livestock and poultry products. The preparation was synthesized and kindly provided by the RiVKNO-ROS Innovation Fund, Moscow.

The drug dihydroethoxyquin is a hydrogenated homologue of ethoxyquin. The empirical chemical formula of ethoxyquin (Santokhin) is 6-ethoxy-2,2,4-trimethyl-1,2-dihydroquinoline, and dihydroethoxyquin is 6-ethoxy-2,2,4-trimethyl-1,2,3,4- tetrahydroquinoline. Thus, in order to obtain dihydroethoxyquin from ethoxyquin, two hydrogen molecules must be attached to ethoxyquin. Molecular hydrogen can easily be attached to organic compounds, such as ethoxyquin, at the site of the double bonds that are present in the ethoxyquin molecule. This is a typical hydrogenation (hydrogenation) reaction.

Why do we focus on antioxidants from the mass of interesting biologically active substances that are very widely represented on the Russian market? Systemic macroecological problems on our planet form aggravated microecological problems in animals, birds, and humans. Unwanted qualities such as general weakening of health, decreased resistance to infectious and non-communicable diseases, reduced stress resistance, inadequate response to even slightly changing conditions and adverse environmental influences and, as a result, decreased animal productivity and have become increasingly common in modern animals poultry, excessive consumption of feed for production and its cost.

The genetic arsenal of adaptive capabilities of organisms of each species is strictly determined. However, in highly productive animals and birds, typical representatives of which are broiler chickens, long-term directed selection for maximum productivity, significantly deformed it. To the detriment of a number of other vital functions, the process of biosynthesis of product components for the human table turned out to be unilaterally hypertrophied. In this regard, the functional adaptive capabilities of such animals to changing environmental system conditions have decreased and the mechanisms responsible for protecting themselves from a wide variety of adverse effects have weakened. In such a situation, antioxidants are called upon to help the body of the farm animal and poultry to provide high growth intensity (productivity).

The present invention is directed to solving the technical problem of increasing the productivity of broiler chickens.

The problem is solved in that, in contrast to the known methods of feeding broiler chickens, including main food with full feed, according to the invention, a new antioxidant, dihydroethoxyquin, is introduced into the main diet instead of conventional antioxidants.

The advantage of the proposed method and the distinguishing feature of the invention: the increase in meat productivity of broiler chickens by the introduction of the new dihydroethoxychine antioxidant in doses of 20 to 200 mg / kg of feed in the patent and scientific literature was not found in the main complete feed. The new antioxidant dihydroethoxyquin used is a solid water-soluble substance, unlike liquid fat-soluble ethoxyquin, it is more stable and has greater antioxidant activity. The use of dihydroethoxychin in production is more technologically advanced, since it can be easily added to the required dose in both feed and drinking water of broiler chickens. The technical result achieved is based on the ability of dihydroethoxychine not known from the prior art to increase the meat productivity of broiler chickens. This circumstance allows us to consider the claimed invention patentable as meeting the condition of patentability "inventive step" (Patent Law of the Russian Federation of 10/14/1992).

Example 1

The experiment was conducted in a poultry factory of Snezhka LLC, Bryansk region. To solve this problem, 4 groups of chickens of 300 goals each were formed. The duration of the experiment is the full technological cycle of broiler chickens growing - from the moment of hatching to slaughter for meat. Broiler chickens were grown in cell batteries at the recommended parameters of planting density, feeding rations, feeding and drinking front, temperature and light conditions.

1. Group - control, is on the main diet (RR).

2. The group is experimental, - OR + dihydroethoxyquin in a dose of 20 mg / kg of feed.

3. The group is experimental, - OR + dihydroethoxyquin in a dose of 70 mg / kg of feed.

4. The group - experimental, - OR + dihydroethoxyquin in a dose of 200 mg / kg of feed.

The results of the experiment are presented in the table.

The live weight of broiler chickens at the end of the growing cycle, grams Broiler Chicken Groups 1st - control 2nd - experimental - 20 mg of the drug / kg of feed 3rd - experimental - 70 mg of the drug / kg of feed 4th experimental - 200 mg of the drug / kg of feed Live weight, g 1878 ± 18 1901 ± 48 1938 ± 17 1950 ± 15 Percentage of Control one hundred 101.2 103.2 103.8

As can be seen from the given factual material, already starting from the minimum dose of dihydroethoxychin (20 mg / kg of feed), the productivity of broiler chickens is increased in comparison with the traditional method of growing by 1.2%. A dose of 70 mg / kg dihydroethoxychin feed in comparison with the control provided a 3.2% increase in productivity. A further increase in the dose of dihydroethoxyquin to 200 mg / kg feed increased the productivity of broiler chickens in comparison with the traditional method of growing by 3.8%.

Claims (1)

A method of increasing the productivity of broiler chickens, including basic full-nutrition, containing a biologically active substance, characterized in that the antioxidant dihydroethoxyquin is added as a biologically active substance in an amount of from 20 to 200 mg per kilogram of dry matter of the main diet.
