Abstract

Abstract Animals such as pigs which are to be slaughtered at slaughterhouses are unloaded from the transport truck and driven into pens and stalled in these for some time, until they are driven out of the pens and over to a stunning apparatus. The pigs of a supplied lot to the slaughterhouse, or part of the supplied lot, are treated as a separate unit during one or more of the above-mentioned stages of treatment, which means that pigs of a unit are to be constantly kept separated from pigs belonging to other units. Each unit may comprise e.g. 15 pigs. The treatment of the animals in units reduces their aggressions, and their well-being is increased, which will result in a lower incidence of rind damages, blood splashings and deviant meat quality of the carcasses. A system for stalling of the pigs includes a number of oblong pens (1), which are placed next to each other. Each of the pens has an entrance gate (6), an exit gate (8) and a driving gate (10) which is movable in the longitudinal direction of the pen. Each pen is equipped with one or more stationary intermediate gates (4), which are placed at such a distance from each other, the entrance gate (6) and the exit gate (8), that the pen is divided into several rooms (3a, 3b, 3c). The size of each room corresponds preferably to the size of the unit of pigs which is to be treated.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 137 words
System for the stalling of animals, said system comprising: partition means for defining a driving-in passage, a driving-out passings, an elongate pen disposed between said passages, a pen entrance for communication between said pen and said driving-in passage, and a pen exit for communication between said pen and said driving-out passage; an entrance gate for opening and closing said pen entrance; an exit gate for opening and closing said pen exit; a driving gate movable longitudinally of said pen; and at least one stationary intermediate gate disposed in said pen at a predetermined distance from said entrance gate and said exit gate to divide said pen into a plurality of sections of predetermined size; said driving gate and said stationary intermediate gate extending transversely of said pen from one side of the pen to the opposite side.
Claim 2
Dependent Claim 137 words
System for the stalling of animals, said system comprising: partition means for defining a driving-in passage, a driving-out passings, an elongate pen disposed between said passages, a pen entrance for communication between said pen and said driving-in passage, and a pen exit for communication between said pen and said driving-out passage; an entrance gate for opening and closing said pen entrance; an exit gate for opening and closing said pen exit; a driving gate movable longitudinally of said pen; and at least one stationary intermediate gate disposed in said pen at a predetermined distance from said entrance gate and said exit gate to divide said pen into a plurality of sections of predetermined size; said driving gate and said stationary intermediate gate extending transversely of said pen from one side of the pen to the opposite side.
Claim 3
Dependent Claim 21 words
The system of claim 1, wherein said sections have a capacity to hold a number of animals corresponding to a flock.
Claim 4
Dependent Claim 11 words
The system of claim 2, wherein said sections hold 12-20 animals.
Claim 5
Dependent Claim 14 words
The system of claim 1, wherein said pen receives a plurality of intermediate gates
Claim 6
Dependent Claim 17 words
The system of claim 1, wherein said at least one intermediate gate is a two-part, side-hinged member.
Claim 7
Dependent Claim 31 words
The system of claim 1, wherein said at least one intermediate gate is made up of two separate gates, which are each hinged to a separate side wall in the pen.
Claim 8
Dependent Claim 27 words
The system of claim 1, 2, 3, 4, 5 or 6 further comprising motor means for driving said driving gate and controls for controlling said motor means.
