title: [Experiments in biological engineering to induce puberty in young female swine. 4: Ovulation period after puberty in animals aged about 200 days, using different combinations of gonadotropic hormones].
abstract: 44 prepuberal gilts were treated with gonadotropic combinations and investigated for ovarian dynamics. 400 PMS + 200 HCG (Suigonan-Vemie) induced ovulations at the 4th day p.i., 100 FSH + 100 HCG resp. 200 FSH + 200 HCG at the 6th day p.i. At the 8,-11th day p.i. the PMS/HCG-treated animals showed corp. lut, in 100, the FSH/HCG-treated in 50 resp. 87% of the cases. A second injection of 250 HCG 3 days after 200 FSH + 200 HCG increased the number of animals which had ovulated. Zystic ovaries (larger than or equal to 11 mm) developed in all groups. Declaration of gonadotropins in "international units".
