(57) Abstract:

Preincubation processing of eggs, chickens, containing different amounts of vitamin a in the yolk, light helium-neon laser LGN-104, a wavelength of 632.8 nm, power of the optical flow of 50 mW/cm2in the exposition of 3 min, a gas discharge lamp DMESG-500, a wavelength of 630-650 nm, the average dose on the surface of eggs 23.1 erg in exposure 5 min and UV lamp CES-400, wavelength 400/185 nm, an average dose of 20 mayor/h 3 min and their complex effects in exposure 3 min each on fetal viability, depending on the mass of eggs, out of day-old Chicks, the dynamics of the post-embryonic development and their subsequent productivity shows when the content of vitamin a in the yolk in the range from 10.8 to 11.2 ág/g observed the largest implementation of the stimulating action of light waves in the area of the red light on the physiological growth and development of birds. 3 table.

The invention relates to poultry and can be used for processing of hatching eggs of chickens.

There is a method to encourage birds by preincubation handling eggs light four helium-neon lasers AGR-12 a wavelength of 632.8 nm, output power of 15 m is of 4.7% (Petrov E. B. The use of beams of helium-neon laser for the stimulation of embryogenesis and enhance the livability of Chicks: author. Diss... Kida. C.-H. N., M.: MBA - 20 C.).

The disadvantage of this method is low efficiency, large power consumption, low performance svetooborudovaniya birds, exposure to light of the same wavelength without regard to the content in embryos of vitamin A.

A method of processing eggs radiation of helium-neon laser of wavelength 632.8 nm, power density on the surface of eggs 50 mW/cm2or mercury-quartz lamp wavelength 400/185 nm, the average dose on the surface of eggs 20 mayor/h, or a discharge lamp wavelength 630-650 nm, the average dose on the surface of eggs 23.1 erg and comprehensively the laser LGN-104, lamps DMESG-500 and he-400 exposures of 3 minutes, which increases hatchability and preservation of broilers (Mamakaev M. Physiological performance, hatchability and viability of broiler chickens when laser light activation: author. Diss... Kida. Biol. Sciences. - Borovsk, 1988, - 18 S., prototype).

The disadvantage of this method is that the hatching eggs were treated radiant energy without consideration and selection of embryos with a high content Icy.

The purpose of the invention is improving the viability of poultry and its productivity.

This goal is achieved by the fact that the hatching eggs - analogues from the same parent stock, age, cross laying hens, at equal weight and quality indicators (units How the shell thickness, the content of vitamin B2and others ), but with different content of vitamin A, which was determined by the method of saponification (Lebedev, P. T. , Usovich A. T. research Methods fodder of animal organs and tissues. Rosselchozizdat, 1976, 289), before incubation were subjected to radiation of helium-neon laser LGN-104, a wavelength of 632.8 nm, power of the optical flow of 50 mW/cm2in exposure 3 min, or gas-discharge lamp DMESG-500, a wavelength of 630-650 nm, an average dose of 23.1 erg/h in exposure 5 min, or ultraviolet lamp CES-400, a wavelength of 630-650 nm, an average dose of 20 mayor/h in exposure 3 minutes and comprehensively light laser LGN-104, lamps DMESG-500 and he-400 in the expositions of 3 min in the experimental setup (Mamakaev M. and others, ed. mon. N 1621208, 1990).

After processing the experimental embryos were incubated in the incubator "Universal 55". The parameters and the mode of incubation meet the requirements of GOST ONTP-4975.

Biological control of razvitiya. Conditioned calves were weighed. Rejected for further research Chicks were placed in a three-tiered cells, BM-3, which support optimum microclimate parameters. Fed broilers on standards developed by breeding.

The results showed (table. 1) that laser light treatment of hatching eggs with a high content of vitamin a (from 10.8 to 11.2 ág/g) reduces embryonic waste, and the output of the conditioned chickens increases when exposed to a helium-neon laser on 8,86% (group 2), the discharge lamp on 6,74% (group 3), the ultraviolet lamp is on 6,41% (group 4) and complex effect on 9,82% (group 5), while similar rates of hatchability of hatching eggs with lower levels of vitamin A(about 7.2 to 7.7 ág/g) was 4,48%; 3.04 from; 4,13 and 6,29% or less of 4.38; 3,70; 2,28 and of 3.53%, respectively.

When the content of vitamin A in the yolk of eggs of 7.2 to 7.7 ág/g dry weight day-old Chicks was in group 1 77,10% by weight of the eggs, in group 2 - 68,09%, 3 - 67,51%, 4 - 68,03% and 5 - 68,81%, with differences between 1 and 2, 3, 4 groups are not mathematical limit of significance (P > 0,05), in 1 and 5 significant (P < 0,05). Similar figures masses of eggs and Chicks when the content of vitamin A in the yolk of eggs from 10.8 to 11.2 ág/g was in group 1 is uppada - significant (P < 0,05).

The use of laser light of LGN-104, lamps DMESG-500 and he-400 for processing eggs with vitamin A content of 7.2 to 7.7 ág/g less efficiently reflected at the output of the mass of Chicks than egg treatment with vitamin A to 10.8 to 11.2 ág/g, when the hatch from the egg weight was higher compared with the control in the processing of light helium-neon laser - 3%, when integrated impact - 3.2%.

Based on the weight of hatching eggs with a high content of vitamins A and Chicks more effectively reflected the impact of the radiant energy of the red part of the spectrum of optical radiation (laser LGN-104, lamp DMESG-500) than ultraviolet light (lamp CES-400).

Higher hatchability conditioned chickens and the dependence of the mass of eggs and Chicks when laser light activation of embryos with a high content of vitamin A are positively correlated with indicators of viability and productivity of broilers in the postnatal embryogenesis (table. 2, 3).

Adjusted laser light mode processing of hatching eggs with different vitamin A content revealed differences in the viability of the offspring at postnatal ontogenesis. The safety of Chicks obtained from AEM vitamin A, by the end of the cultivation was higher in group 2 - 4,95% (P < 0,01), 3 - 4,20% (P < 0.01), and 5 group - 3,43% (P < 0.05), and at 1 and 4 groups differences were not reliable and was 1.32 and 2,47%, respectively.

Preincubation laser light activation of the embryos of chickens beef cattle with different levels of vitamin A increases average daily gain in live weight of broiler chickens. A higher liveweight gain experienced Chicks continue until the end of fattening, and is characterized by a gradual decrease contrast results average daily gains and body weight of control and experimental groups of chickens.

Daily gains and average live weight of broiler chickens obtained from eggs with high content of vitamin A, were significantly above the rate of fattening poultry obtained from eggs with lower levels of vitamin A.

Effect of monochromatic coherent red light helium-neon laser and monochromatic red light discharge lamps more efficiently reflected on the processing of hatching eggs with a high content of vitamin A, less than. The difference in average daily liveweight gain of broiler was a 2-week age - 14,70 the military when exposed to radiation of the discharge lamp, while similar figures apply ultraviolet light was 4,71; 2,69; 2,72 and 4.12% for the relevant age periods of research.

Thus, the impact of red light helium-neon laser and gas-discharge lamps more efficiently reflected on egg hatching with a high content of vitamin A, which shows the implementation of the stimulating action of the red part of the spectrum of optical radiation through the activation of vitamin A in the yolk of the treated embryos.

The selection of embryos of chickens laser light for processing, including determination of vitamin a in the yolk and preincubation processing eggs monochromatic coherent red helium-neon laser LGN-104, a wavelength of 632.8 nm, power of the optical flow of 50 mW/cm2in exposure 3 min, or monochromatic red light discharge lamp DMESG-500, a wavelength of 630 to 650 nm, the average dose 23.1 erg in exposure 5 min, or ultraviolet lamp CES-400, wavelength 400/185 nm average dose of 20 mayor/h for 3 min and comprehensively the laser LGN-104, lamps DMESG-500 and he-400 in exposure 3 min each, characterized in that the processing of eggs radiant energy in the same mode on take into account the viability of hatched Chicks and their subsequent productivity.
