An apparatus for spraying and treatment of livestock has a frame with adjustable side sprayer nozzles, adjustable overhead spray nozzles, and bottom sprayer nozzles. Sensors attached to adjustable sensor bars determine actuation of the sprayer nozzles as animals enter a chute. A combination of side guide rails and spring rods keep animals centered while passing through the chute. A trailer tongue and wheels are attachable to the frame for transport of the apparatus as a trailer. Gates are hinged to the frame for use of the apparatus with an opening in a fenced area.
