Labor is in short supply in animal agriculture. One time-consuming task is estrus detectionin gilts. Stimulation with a live boar causes the onset of puberty in young gilts. Typically, a liveboar is used to stimulate and identify estrus in the gilts by exposing the gilts to him. Recently, aboar pheromone (BB) was developed to replace the use of a live boar for sows. Additionally, a novelvautomatic sprayer used as environmental enrichment (EE) by gilts for the selfvadministration of BB has been developed by this laboratory. A commercial study was conducted to determine whether the use of a live boar could be replaced with a simple EE sprayer, allowing gilts to self-administer BB. Our objective was to determine whether the number and percentage of gilts in estrus obtained using live boars was comparable to self administration using an EE sprayer containing BB. A total of 242 gilts were randomly assigned to either a live boar (BOAR) or BB self-administration using the environmental enric
