[Effect of various injection times in ovulation stimulation in gilts following previous biotechnical puberty induction].
A conclusion derived from the slaughter of 69 gilts was that no role was played by the time intervals tested between puberty induction, using 500 IU of PMS and 250 IU HCG, and subsequent action to stimulate ovulation. Very good follicle maturation and follicle formation as well as the usual uterus and ovary weights were observed, no matter whether 500 IU of HCG were injected to stimulate ovulation 54, 72 or 78 hours after puberty had been induced. Ovulation was very efficiently synchronised by 500 IU of HCG in all three groups in which the ovulation figures relative to follicle formation 120 hours from puberty induction were 92.6, 94.6 or 92.7 per cent.
