Animal handling device
Described herein is an animal handling device in the form of a cattle crush with automated headbail capture, back bar operation and positional sensing along with methods of use thereof. The crush and method offer automation for functions that in the art have been largely manual and inherently labour intensive, physical and even potentially dangerous for the operator and/or animal.
1. An animal crush system comprising:
a headbail at an exit end of the animal crush system configured to interact with a neck of an animal passing through the animal crush system, the headbail comprising:
opposing barriers, the opposing barriers being moveable between a fully open position, a fully closed position, and a variable position, the variable position comprising the opposing barriers in a position located intermediate the fully open position and the fully closed position;
an actuator configured to adjust a distance between the opposing barriers;
a potentiometer configured to sense the distance between the opposing barriers by measuring electrical impedance; and
a controller comprising a dial that is communicatively coupled with the actuator, the dial configured to be adjusted in position to a datum position, each position of the dial corresponding to an impedance measurement of the potentiometer equivalent to the fully open position, the fully closed position, and the variable position;
the datum position based on an animal characteristic selected from: animal shape, animal size, animal age, animal species, animal sex, animal body condition score (BCS), animal ID tag, or any combination thereof;
wherein the potentiometer further measures a change in impedance once the datum position is set caused by presence of an animal and uses the change in impedance to automatically cause the actuator to move the opposing barriers to the fully closed position.
2. The animal crush system of claim 1 , wherein in the fully open position, the opposing barriers do not block movement of an animal through the opposing barriers.
3. The animal crush system of claim 1 , wherein in the fully closed positioned, the opposing barriers impose sufficient force on an animal's neck positioned between the opposing barriers to capture the animal and prevent movement of the animal forwards or backwards.
4. The animal crush system as claimed in claim 1 , further comprising:
one or more animal position sensors; and
at least one backbar;
wherein the controller is further configured to:
automatically move the at least one backbar from a retracted position to an animal urging position when the one or more animal position sensors sense a presence of an animal at a predetermined distance in the animal crush system.
5. The animal crush system as claimed in claim 1 , further comprising:
multiple load cells located in varying positions about a base of the animal crush system;
wherein the controller is further configured to:
receive weight measurements from the multiple load cells and a location of the multiple load cells sending a weight measurement;
from the weight measurements and load cell locations, calculate an animal position within the animal crush system; and
instruct the actuator to move the opposing barriers to the fully closed position when the animal position is calculated as being proximate the opposing barriers.
6. The animal crush system as claimed in claim 1 , wherein, before animals are to be handled, an individual animal characteristic is used to set a datum position of the opposing barriers.
7. The animal crush system as claimed in claim 1 , wherein, before animals are to be handled, the animal characteristic of a general mob of animals is used to set a datum position of the opposing barriers.
8. The animal crush system as claimed in claim 1 , wherein the dial is located on the animal crush system.
9. The animal crush system as claimed in claim 1 , wherein the dial is located on a remote controller.
10. The animal crush system as claimed in claim 1 , wherein a position of the dial is set manually.
11. The animal crush system as claimed in claim 1 , wherein a position of the dial is set automatically based on the animal characteristic.
12. The animal crush system as claimed in claim 1 , wherein the dial provides a visual prompt to illustrate the position of the opposing barriers.
