BEEF CATTLE IDENTIFICATION USING PCA AND OTHER CATTLE IDENTIFICATION METHODS

Various Cattle identification methods are discussed in this paper. Cattle identification methods can be classified into 3, viz. Mechanical methods, Electronic methods and Biometric methods. Tagging, branding and tattoos are most commonly used mechanical methods. Three main electronic identifiers are ear tags, ruminal boluses and injectable transponders. DNA profiling, Iris imaging, Retinal imaging and Muzzle pattern imaging are biometric methods. All these are discussed in this paper with their merits and demerits. Finally beef cattle identification using eigen muzzle approach is studied and implemented.
