An automated device for the controlled feeding of substances to animal containment recipients in an animal breeding facility, which includes at least one rack for animal containment recipients arranged in a line comprising a plurality of animal containment recipients, wherein said recipients are arranged in the form of a grid on said rack, comprising: a robot, comprising a locomotion platform; a lifting mechanism; a feeding platform; a feeding circuit; and a central processing unit; wherein the robot is configured to travel on at least one horizontal, linear track, which is disposed parallel to each rack for animal containment recipients disposed in a line, wherein a reflective strip is disposed next to a terminal position of said horizontal, linear track; wherein the locomotion platform comprises at least one drive wheel; a first motorization unit and a sensorial navigation unit; the sensorial navigation unit being configured to locate and navigate the platform in the workspace and to detect the reflective strip and the first motorization unit configured to move the locomotion platform along the horizontal, linear track; wherein the lifting mechanism comprises a lifting rod, which is perpendicular to the horizontal, linear track; and a second motorization unit, which is configured to move the feeding platform along the lifting rod; and the lifting mechanism is connected to the locomotion platform; wherein the feeding platform comprises a gear rack, which is connected to a feed head; a sensorial feeding unit, which is configured to send data to the central processing unit regarding the position of the feed head in relation to the feeding zone of the animal containment recipient; a second processing unit; a third motorization unit, which is configured to move the gear rack along a horizontal axis, which is perpendicular to the lifting rod, for the feed head to reach the substance feeding zone in an animal containment recipient; wherein the feeding circuit comprises one or more feeding circuits selected from the group consisting of a dry feeding circuit and a liquid feeding circuit; wherein the central processing unit receives data regarding position, orientation and speed relating to the locomotion platform, said data being collected by the sensorial navigation unit and processed by the central processing unit; wherein the central processing unit receives data regarding feeding parameters for each animal containment recipient, said data being collected by the sensorial feeding unit and processed by the second processing unit; wherein the central processing unit controls the movement of the locomotion platform along at least one horizontal, linear track and along at least one passage adjacent to a horizontal, linear track, the movement of the feeding platform along the lifting rod and the feeding of the animal containment recipients by the feed head. wherein the robot is configured to travel on at least one horizontal, linear track, which is disposed parallel to each rack for animal containment recipients disposed in a line, wherein a reflective strip is disposed next to a terminal position of said horizontal, linear track;
