PROBLEM TO BE SOLVED: To provide a pilot burner nozzle that can be cleaned simply and quickly even if installing the bruder, and furthermore, enables cleaning the nozzle even if maintaining an ignited state, and provide a bruder for livestock.SOLUTION: A pilot burner nozzle PN is used for a bruder B for use in livestock breeding. The pilot burner nozzle PN includes a nozzle body 10 having a gas ejection hole 10b and a gas flow path 10h for connecting a gas inflow hole 10a, and a cleaning shaft 11 coaxially provided with the central axis of the gas ejection hole 10b in the gas flow path 10h. The cleaning shaft 11 is provided movably between a projected position with the tip projected from the gas ejection hole 10b and a storage position with the tip disposed inside from the gas ejection hole 10b.SELECTED DRAWING: Figure 1
