Description

The invention relates to the field of agriculture, namely to industrial technology for the production of broiler meat in order to stimulate digestion, improve metabolism, and ultimately to obtain a high live weight of broilers in the shortest growing time (at the age of 39 days) and can be used in medicine , biology and crop production.

There is a method of increasing the productivity of a bird, including sequential periodic illumination and dimming, and during the lighting period they feed and water, during which they are stimulated by intermittent tone messages (see SU No. 1625467, A01K 67/02, 1988).

The main disadvantage of this method is the complexity of the design and process.

There is a method of stimulating the productivity of fattening and increasing the digestibility of feed of poultry of meat breeds by combining exposure to it with visible light radiation and stimulation with tone parcels that mimic the voice of the bird during its feeding, drinking and darkening during the rest (see SU No. 1831281, A01K 67/02 , 1991).

The main disadvantage of this method is the complexity of the design and process.

A known method of biostimulation of poultry by feeding, drinking and optical exposure, characterized in that on the chest area of broiler chickens at one day old they are exposed to a single red light emitting diode radiation, the radiation of which is covered by an information biologically active matrix (IBAM) (see RF No. 2351124 , A01K 31/00, 2009) is a prototype.

The main disadvantage of this method is the incoherence and monochromaticity of LED radiation, resulting in a small effect of biostimulation.

The objective of the invention is to increase the safety and categorization of poultry, better digestibility of feed, increase productivity while reducing energy consumption, feed consumption, water, electricity, cost and labor content.

The task is achieved in that the chest area of the newly-fed broilers of the day old is once exposed to the low-intensity scanning laser radiation of the red range, transmitted through the spatial modulator once, subject to the following parameters: wavelength λ = 658 nm, pulse duration τ _and = 250 ns , pulse frequency f = 80 Hz, laser radiation power P _rad = 50 mW, radiation exposure of 60, 120 and 180 s in a device containing a movable carriage on which a solid-state laser rotating a mirrored tetrahedral prism, a reflecting mirror, and a spatial modulator consisting of a glass slide (310 × 220 × 4 mm) with a biologically active substance deposited on it, and a laminated coverslip (310 × 220 × 2 mm).

The advantage of the method lies in the fact that exposure to low-intensity scanning laser radiation through a spatial modulator 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 device for biostimulation of poultry is designed for simultaneous exposure to low-intensity scanning laser radiation through a spatial modulator for 50 heads of broiler chickens. It consists of a movable carriage on which a solid-state laser, a rotating mirror tetrahedral prism and a reflecting mirror are mounted, and a spatial modulator consisting of a slide (310 × 220 × 4 mm) with a biologically active substance coated with a laminated cover glass (310 × 220 × 2 mm).

Figure 3 shows a scanning diagram of broiler chickens with laser radiation.

The biostimulation method is as follows.

A rotating prism unfolds the incident laser beam in a row, a reflecting mirror directs the expanded laser beam to the spatial modulator (which is an anisotropic quasi-liquid crystal diffraction grating). The movable carriage performs a sequentially return scan along the monolayer of the spatial modulator with a laser beam (duration of one scan cycle 10 s, exposure time per point in one cycle 0.1 s), as a result of which an interference laser field is formed at each point (with its speckle structure), which, acting on the chest area of broiler chickens, leads to the stimulation of biological processes.

Example.

Clinically healthy chickens (cross-country Hubbard) of daily age were formed in seven separate groups (50 goals in each of the cages), taking into account the origin, age and live weight. Each formed group consisted of a control and experimental group. 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 in the installation (Fig. 1) was exposed to low-intensity scanning laser radiation without a spatial modulator and with a spatial modulator. As a component of the biologically active substance of the spatial modulator, the biologically active additive chavanprash and lemon peel flour 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 exposure of the scanning laser radiation of the red range was carried out by a solid-state laser of the type (HLDH-660-A-50-01), the radiation of which is closed by a spatial modulator, subject to the following parameters: wavelength λ = 658 nm, pulse duration τ _and = 250 ns, frequency pulses f = 80 Hz, laser radiation power P _rad = 50 mW, radiation exposure of 60, 120 and 180 s.

At the end of the experiments, slaughter was carried out, slaughter indicators were determined by the mini-herd 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 use of scanning laser exposure through a spatial modulator on the live weight gain of broiler chickens, which is confirmed by an increase in their growth, development and live weight (see Fig. 4, 5). So, in the case of applying scanning laser exposure through a spatial modulator (with chavanprash) at an exposure of 120 seconds, the meat chickens of the experimental group on the day of slaughter exceeded the weight of the experimental group by 26.93%, while without the spatial modulator by 20.51%.

The low-intensity exposure to scanning laser radiation depended both on the type of component of the substance of the spatial modulator and on the exposure time. The maximum value of the increase in the initial live weight was obtained when using the component of the spatial modulator biologically active additives chavanprash (figure 4) when the exposure exposure of 120 seconds and amounted to 42.11 times, respectively. If used as a component of a spatial modulator of flour peel of a lemon (figure 5), the highest values of this indicator were also obtained with an exposure of radiation of 120 seconds and amounted to 41.20 times.

In general, the increase in the initial live weight of broiler chickens ranged from 35.12 to 40.75 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 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 control values. 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 consumption 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 exposure to scanning laser radiation through a spatial modulator depends on the type of substance used, the components of the spatial modulator, and the exposure time.

This method is tested at the poultry farms "Novgorod" and "Clear Dawns" Krestetsky district of the Novgorod region.
