Abstract: A saliva test device includes: a means for generating an approach detection signal; a means for generating a contact detection signal; a drinking water supply unit for controlling the supply of drinking water in response to at least one of approach detection signals and contact detection signals; a pump for suctioning and collecting saliva in response to a contact detection signal; a test unit for testing whether a disease is present; a communication unit for informing test result information; a control unit for generating a system driving control signal in response to an approach detection signal, generating a pump driving control signal in response to a contact detection signal, generating a drinking water supply control signal in response to saliva collection, and controlling transmission of the test result information; and a memory for storing data. The saliva test device reduces animal stress and testing fees and improves productivity.

Abstract: Provided is an apparatus of measuring the amount of feed. The apparatus includes a feed tank, a plurality of sliders, a case, a plurality of guides, and a weight sensor. The feed tank includes a discharge tube disposed at a lower part thereof and includes a body filled with feed. The plurality of sliders is radially and vertically disposed on an outer surface of the feed tank. The case has a discharge tube insertion hole at a lower part thereof to receive a discharge tube of the feed tank and receives the feed tank. The plurality of guides is radially and vertically disposed on an inner surface of the case. The weight sensor is disposed under the guide and makes contact with a lower end of the slider of the feed tank to measure the weight of the feed tank and feed.
