Abstract
A predator control collar (10) includes a pair of toxic filled pouches (12) and (14) attached to elastic straps (16) and (18) for expansion. The pouches (12) and (14) include a fill plug (22) for a needle to inject a liquid predicide into the pouches. The pouches (12) and (14) are positioned about the elastic straps (16) and (18) so that they are maintained in the general region below the ear of the livestock, and the straps (16) and (18) are of sufficient elasticity to expand with the increase in the size of the animal's neck as it grows to full maturity.
