    The invention relates to the meat industry, in particular to methods for stunning slaughter animals. The purpose of the invention is to improve exsanguination by maintaining the work of the heart during stunning. The method involves exposing animals, in particular pigs, to reduced air pressure followed by an increase in pressure to the original atmospheric pressure. The reduced pressure is created in two stages: in the first stage, the pressure is reduced to 15 . 10 3 Pa for 3 s and on the second - from 15 . 10 3 to (5-2) . 10 3 Pa for 4 s, and the pressure (5-2) . 10 3 Pa is maintained until the reflexes disappear in animals or within 30 s. 1 hp f-ly.

    WITH
    The invention relates to the meat industry, in particular to methods for stunning slaughter animals.
    The purpose of the invention is to improve
    bleeding by keeping the heart working while stunning.
    The method involves exposing animals, in particular pigs, to reduced air pressure, followed by increasing the pressure to the original atmospheric pressure. The reduced pressure is created in two stages: in the first stage, the pressure is reduced to 15x10 Pa for 3 s and in the second stage from 15X10 to (g Pa for 4 s, and the pressure (5-2) is maintained) until the reflexes disappear in animals or in for 30 s.
    Increasing the pressure to the initial level is preferably carried out instantaneously.
    With a two-stage pressure reduction in the first stage to 15 flO% a for 3 s, the organs of the animal are prepared for a further decrease in pressure, while the reflexes in the animals remain for some time, thus avoiding the stressful effects of the process on the animals upon their stunning .
    In the second stage, the pressure is reduced
    : from 15X10 to (5-2) for 4 s, with this, a rapid relaxation of the body of the animal without spasm occurs. The heart of the animal continues to work. Low pressure reached at Vto: o

    This stage, i.e., (5-2) xjO riaf, maintains a certain time (30 s) until the reflexes are resolved in animals. The deeply relaxed state of the animal while working in the heart allows the best way to carry out the subsequent bleeding, which affects the quality of meat,
    The two-stage pressure reduction allows, through preparation, the animal in the first stage to reach more extreme values of air pressure in the second stage without injuring the animals. Thus, the features of the method also allow to speed up the stunning process as a whole,
    After the animals have lost their reflexes (t, e, their stunning has occurred), the air pressure is retracted to the initial one, the pressure can be performed almost instantly, while the animals remain relaxed without reflex state E; a period of time sufficient for exsanguination.
    Example, Pigs adapted to atmospheric pressure, placed in a chimer for stunning, equipped with sealing means and means for rapidly lowering the air pressure in the chamber. The chamber is sealed and for 3 seconds the air pressure is reduced from atmospheric to 15x1CgPa. When the pressure reaches 15x1 (GPa, the air pressure is further lowered to 3x1 (hPa for 4s.
    Thus, the process of reducing the air pressure in the chamber is carried out for approximately 7 seconds. The pressure Pa is maintained for 30 s until the disappearance of animal reflexes.
    Then the pressure in the chamber is raised to atmospheric by depressurization25

    Invention Formula
    1, A method of stunning before exsanguinating slaughter animals adapted to atmospheric pressure, in particular pigs, involves exposing animals to reduced air pressure followed by an increase to original atmospheric pressure, characterized in that, in order to improve exsanguination by stunning heart work, reduced the pressure is created in two stages in the first stage, the pressure is lowered to 15-10 Pa during
    3 s and in the second stage - from up to (5-2) 10 Pa for 4 s, and the pressure (5-2) 10 Pa is maintained until the reflexes disappear in animals or for 30 s,
    2, the method according to claim 1, differs ayushi and in that the step of pressure to the initial level is carried out instantly.
    Priority points and features:
    07.05.87po n, 1, except for signs relating to the fact that in the first stage the pressure is reduced for 3 s, on the second - within 4 s, and the pressure (5-2) -10 Pa is maintained for 30 s, and also n, 2,
    03.16.88 according to claim 1, concerning that in the first stage the pressure is reduced in 3s, in the second - within 4 s, and the pressure (5-2) is maintained for 30 s.
