Studies on the oestrus and ovarian activity during five successive oestrous cycles in gilts



Studies on the oestrus and ovarian activity during five successive oestrous cycles in gilts



Acta Veterinaria Scandinavica 21(4): 677-688



The study comprised 11 crossbred gilts (Swedish Landrace X Yorkshire). Heat control was carried out twice daily and comprised a careful inspection of the vulva and check of the standing reflex with and without a vasectomized boar. The ovaries were inspected after the first, third and fifth heats by laparoscopy. Blood samples for progesterone determination were taken once a week during the whole observation period. The genital organs were examined after slaughter.
