The invention relates to a feed conversion efficiency measuring device for mutton sheep, which is composed of a rack, a front
wall plate, side wall plates, an automatic feeding door, an
ear tag identification mechanism, an
infrared proximity identification mechanism, a feeding mechanism, a weight weighing mechanism and a feed weighing mechanism, the front end, the left side and the right side of the rack are respectively provided with the front
wall plate and the side wall plates; a feeding opening is formed in the lower end of the front
wall plate, an automatic feeding door is installed at the position of the feeding opening, an
ear tag recognition mechanism is installed at the upper end of the feeding opening, installation arms are installed on the two side wall plates,
infrared proximity recognition mechanisms are installed on the installation arms, and a feeding mechanism is arranged between the two side wall plates at the rear end of the front wall plate. The feed weighing mechanism is arranged at the lower end of a
discharge port of the feeding mechanism, and the weight weighing mechanism is arranged at the front end of the front wall plate. The feed conversion efficiency measuring device has the advantages of being capable of guaranteeing balanced feeding, uniform in
ingestion, accurate in measurement, clean and sanitary, capable of achieving information and
intelligent control, easy to achieve and the like, and feed is saved.
