Hormones and Sex Steroid Receptors in Female Pig
Permanent URI for this collection
Mating of sows by a boar results in a greater increase of cortisol than
AI and without an elevation of PG-metabolite levels, which was seen in both the inseminated
groups. It was also demonstrated that IUI-group had an earlier significant increase of PG-metabolite
levels than sows inseminated conventionally. Further investigation using different semen extenders
or even different type of insemination catheters might be helpful in understanding the reason for
an immediate increase of PG-metabolite after insemination but not after mating.
