Description

The invention relates to agriculture, namely to industrial technology for the production of broiler meat, and can be used in biology and crop production.

A known method of biostimulation of poultry, which consists in irradiating eggs before laying for incubation with optical radiation, formed to enhance the biostimulating effect, by an injection semiconductor radiation source with a dose of 1-1000 J / m ² , in particular an injection semiconductor laser, LED or LED with a polarizer (see RU No. 2101939, A 01 K 41/00, 1998).

The disadvantage of this method is the high dose of the radiation source, as a result of the low effectiveness of the biostimulating effect.

A known method of growing young farm poultry, which consists in irradiating the eggs before laying in the incubator or chickens of the first days of life with low-intensity defocused laser radiation of 0.87-0.98 μm, a power of not more than 1.0 W / kW, exposure 1-10 min. Laser radiation is modulated in frequency in the range of 10-2000 Hz (see RU No. 21119747, A 01 K 31/00, 1998) - a prototype.

The disadvantage of this method is the defocusing of the laser, which leads to a decrease in the biostimulating effect.

The objective of the invention is to increase the high live weight of broilers in the shortest growing time by stimulating digestion and improving the metabolism of broiler chickens.

The task is achieved by the fact that broiler chickens at the age of 24 days are exposed to a ten-minute aeroionization (AI), followed by low-intensity exposure to laser radiation (LLLT) through an information biologically active matrix (IBAM).

The advantage of the method lies in the fact that the use of a ten-minute AI with the subsequent exposure to LILR through IBAM leads to a significant increase in the live weight of broilers (at the age of 39 days) due to stimulation of digestion, improved metabolism and more efficient use of nutrients of complete ration in chickens.

The drawing shows a diagram of low-intensity exposure to the area of the breast of meat chickens with an infrared laser through the IBAM, where:

Features of the method of growing broiler chickens are as follows. Clinically healthy chickens of daily age were formed in four separate groups (16 goals in each of the cages), taking into account the origin, age and live weight. Each formed group consisted of a control and four experimental groups. Broiler chickens were fed typical full-ration feeds in which the content of metabolic energy, nutrients and biologically active substances was consistent with existing recommendations. Each experimental group was exposed to a ten-minute AI followed by LLLT exposure through IBAM with various components. As a component of IBAM, pomegranate peel flour (Table 1), mandarin (Table 2), lemon (Table 3) and dietary supplement (BAA) Chawanprash (table 4) were used. During the experiments, the live weight of broiler chickens was determined at the daily age, then on the 7th, 14th, 21st, 28th day and immediately before slaughter - on the 39th day.

The low-intensity LI of the infrared range was carried out by the Uzor-2K-Super semiconductor laser apparatus, the beam of which was blocked by an IBAM, consisting of a paper or glass container with a biologically active substance, on the chicken breast area under the following parameters: wavelength 890 nm, pulse duration 260 ns, pulse repetition rate of 80 Hz, radiation power 0.3 W, radiation exposure 8.15, 30 and 60 s (see drawing).

At the end of the experiments, slaughter was carried out, slaughter indicators were determined by the ministad method.

The results of the experiments showed that the gain in live weight of broiler chickens of all experimental groups was outstripped in comparison with the control group on day 39 of rearing.

The experiments showed the effectiveness of the aeroionization of the house, both individually and in combination with the subsequent effect of LLLT on the live weight gain of broiler chickens, which is confirmed by an increase in their growth, development and live weight (see Tables 1, 2, 3, 4 ) So, in the case of using a ten-minute AI, the meat chickens of the experimental group increased their initial weight by 30.44 times, while in the control only 20.42 times. The subsequent low-intensity exposure to LI depended both on the type of the IBAM component and on the radiation exposure. In general, the increase in the initial live weight of broiler chickens ranged from 23.93 to 35.67 times. The maximum values of this indicator were obtained when “chavanprash” was used as an IBAM component (Table 4) when the LLLR exposure was 30 and 8 seconds, and amounted to 35.67 and 30.13 times. When using lemon peel flour (Table 3) and pomegranate (Table 1) as the IBAM component, the highest values of this indicator were also obtained with radiation exposure of 30 and 8 seconds, respectively, and amounted to 27.53 and 27.17 times.

The meat chickens of the experimental groups differed from the control group in greater massiveness. At the same time, large values of measurements of articles were noted (body length, width and girth of the chest, keel length).

When slaughtering, the masses of gutted, semi-gutted and gutted carcasses, as well as the output of the gutted carcasses of broiler chickens from the experimental groups were higher than those in the control. The mass of a number of organs and muscles also exceeded the control indicators. This applies to the mass of the pectoral, femoral muscles, as well as the mass of the neck, liver and heart.

Thus, with the same expenditure of feed, but with different factors affecting the body, the growth and development rate of broiler chickens increases. It should be borne in mind that the effectiveness of the LLLT effect depends on the exposure of the radiation and the type of IBAM component used.

This method has been tested at the poultry farm CJSC "Agricultural concern Veliky Novgorod."
