title: [The dose precision of PMSG for gilts and old sows in procedures for ovulation synchronization. 2. Organometric and histometric findings after diagnostic slaughtering].
abstract: An account is given in this paper of organometric and histometric findings obtained, on three farms, N, B, and D, from ovaries, uteri, and oviducts of biotechnologically treated gilts and adult sows, using differentiated PMSG doses (600, 800, and 1,000 IU on gilts and adult sows of N and B; 500, 1,000, and 1,500 IU on gilts of D). Ovulation potentials were within the biological normal in response to low dosage (with an average of 12 to 15 follicles in gilts and 17 in adult sows). The 800 IU dose caused significant stimulation, which had to be interpreted as overstimulation for PMSG-sensitive probands of N. Ovarian reaction and induced cycle should by duly considered for interpretation of histometric findings.
