PURPOSE: An animal body composition analyzing apparatus is provided to effectively fix an animal in an animal body composition measurement process, thereby precisely measuring the body composition of the animal.CONSTITUTION: A plurality of electrode materials(110) respectively includes one or more voltage measuring electrodes and current supplying electrodes touched to the feet of an animal. A supporting part(120) supports the electrode material in a lower part. A measurement part(130) applies a current to the feet of the animal touched with the current supplying electrode of the electrode material. The measurement part measures voltage applied to the feet of the animal touched to the voltage measuring electrode. A body composition analysis part(140) calculates bio-impedance of the animal using the voltage measured by the measurement part. The body composition analysis part analyzes the body composition of the corresponding animal using the calculated bio-impedance of the animal.COPYRIGHT KIPO 2012본 발명은 동물용 체성분 분석 장치에 관한 것으로, 동물의 체성분 측정시 동물의 발이 접촉되는 전극체를 지면에 대해 특정 높이로 이격 설치하여 동물이 움직임을 주저하도록 함으로써 간편하고 정확하게 동물의 체성분을 측정할 수 있도록 한 것이다.
