The way that eliminates the harmful effect of magnetic perturbations on the body of birds
(57) Abstract:The invention relates to poultry and can be used for growing and fattening poultry in floor maintenance and aims to increase the resistance of the body of birds. Specified biological outcome in the way that is achieved by the fact that during periodic magnetic storms on earth to reduce the effects of stress metal mesh cells kasemset, at floor maintenance the number of birds placed in mesh metal shielded enclosures, grounding for the period of the magnetic perturbations of the earth. 1 C.p. f-crystals, 1 table. The invention relates to veterinary medicine and is intended to increase the resistance of the organism hens egg and beef cattle.Widely known way to protect chickens from negative factors fed chickens at floor maintenance in conditions of poultry (Mymrin I. A. Broiler poultry house climate., M Rosagropromizdat, 1989, S. 158 - 162)
The disadvantage of this method content is that this method nepozvoljaet to protect birds from the harmful effects of magnetic disturbances of the earth in unfavorable days each month.Know what when creating appropriate conditions technical means.The disadvantage of this method is that during the critical days - magnetic disturbances chickens, especially during the first two weeks, while in the brooder, cannot maintain the constancy of the resistance body resistance and high immune status of the organism, because the protective mechanism is not formed and the state of the organism depends on the environment, the more heat even in chickens is higher than the heat buildup (Fisinin Century. And., Tardatyan, A. Industrial poultry farming, M. Agropromizdat, 1985, S. 220 - 234).Only 90 days of age in chickens finally forms the juvenile plumage for stable operation of the mechanism of thermoregulation. There is also known a method of antiradiation protection of animals (RF patent N 2045966, class A 61 N 2/08, 1995, for the protection of animals before and after x-ray irradiation aerial dose animals were placed for 3 hours in an ungrounded film camera.The disadvantage of this method is the lack of independent (Autonomous) metal screen mesh, which would in time of the magnetic perturbations of the earth could be ground, and in normal (auspicious days of the month) to remove zaseniti high resistance and immunological status in cultured chick, was simple in design, compact and almost easily enforceable, sparing the body of chickens during the formation of all body systems, reduction of area, volume, the strength of the magnetic perturbations in the critical days of the month.This objective is achieved in that the proposed method eliminates the negative effect of geomagnetic disturbances on the body of birds, containing mesh metal screens in cages at floor maintenance birds, which in the period of the earth's magnetic perturbations are grounded in ordinary days, the ground stopped disconnecting.Comparative analysis of known and proposed methods shows that the difference of the latter is, first, the implementation of the method is using the shielded metal mesh screen, secondly, shielded metal screen during magnetic storms in bad days is grounded on auspicious days metal screen does not require grounding.Our proposed method differs from the method radioprotective protect the body of the animal to the fact that in our way:
1. Mesh metal screen antilochos and antimagnetic impact in the period of geomania birds, installed in pairs symmetrically to each other;
4. The screen protects the bird from:
and/ geomagnetic effects in the critical days of the year,
b/ natural radiation effects,
in/ lightning and electrical discharges.The effectiveness of the present invention and its use in practice is reflected in the table.The table shows that after fattening chickens in cages with a grounded mesh metal screen during magnetic disturbances of the earth decreases the mortality of Chicks is 8% less than in the way of fattening chickens, when a metal mesh screen is missing or there but not earthed during magnetic storms. Average daily gain (the gain in live weight) for fattening chickens contained in cages with mesh metal screens, grounded during magnetic disturbances, was 26 g, and when feeding in areas where there are no shielded enclosures, the gain was 14 - 16, 1. The way that eliminates the harmful effect of magnetic perturbations on the body of birds at floor maintenance, including their placement in the cages with a wire mesh fence, characterized in that during geomagnetic disturbances earth metal 2. The method according to p. 1, characterized in that the metal screens installed in pairs symmetrically to each other.
FIELD: poultry science.
SUBSTANCE: one should irradiate eggs before incubation with the light of He-Ne laser LHN-104, wave length being 632.8 nm, power density at eggs surface being 50 mW/sq.cm/sec, with red light of fluorescent lamp DNESG-500, wave length being 630-650 nm, power at eggs surface being 23.1 erg and with ultraviolet from DRT-400 lamp at wave length being 185-400 nm, average dosage at eggs surface being 20 merg in 3-min-long exposures.
EFFECT: higher resistance to pullorosis in poultry.
