A liquid basting injector for poultry or the like has a reservoir of liquid basting material connected by a conduit to a hollow cylindrical dispensing chamber in which a dispensing piston and rod are mounted for reciprocation; power cylinder means has a power rod connected to the dispensing piston and rod for reciprocating same to draw a measured amount of basting material into the chamber and then dispense it through an injector needle connected to the chamber by a flexible hose. An adjustable stop is positioned to be engaged by the upper end of the power rod of the power cylinder for limiting the extent of movement of the power cylinder and the dispensing piston to adjust the amount of liquid basting material drawn into the dispensing chamber in accordance with a predetermined value dependent upon the weight of the poultry into which the liquid basting material is to be injected. A dial type indicator indicates the amount of liquid basting material that can be drawn into the chamber for any adjusted position of the abutment means. A circuit includes selectively and automatically operable valves for continuously reciprocating the dispensing piston for circulating cleaning between the reservoir and the injecting needles in one mode of operation or for effecting a dispensing operation of basting material under the control of a foot valve in another mode of operation.
