Abstract

The peripheral plasma levels of testosterone were measured before and after Gn-RH injection in boars with normal sexual behaviour and in boars refusing to mount a dummy sow or oestrous pigs. The testosterone response in peripheral plasma was similar for the two groups of boars. Peak values were reached within 2–4 h, and pretreatment levels were found 7–12 h after the administration of Gn-RH.

Sammanfattning

Testosteronkoncentrationen mättes före och efter Gn-RH injektion hos galtar med normal könsdrift och hos galtar som vägrad-e bestiga suggfantom eller brunstigt honsvin. Testosteronmönstret i perifera blodplasman var lika i de båda galtgrupperna. Högsta nivån erhölis inom 2–4 timmar och ursprungsnivån registrerades 7–12 timmar efter Gn-RH injektionen.
