To test the sites of insemination, 136 goats synchronized by treatment II were inseminated twice, 38 and 48 hours after sponge withdrawal using 300 x 10 6 sperm as fresh semen. The sites of insemination were vaginal, superficial and deep cervical, and intrauterine. The differences were significant. Their sucessful use is limited by nutritional and economic considerations  aGoats  aHormones  aReproduction  aReproductive performance  aVenezuela  aCaprino  aEficiência reprodutiva  aHormônio  aProdução animal  aReproducão animal  aSincronização do cio  aOestrus synchronization1 aESTEVA-HERNÁNDEZ, A.1 aMADRID-BURY, N.  tIn: INTERNATIONAL CONFERENCE ON GOAT PRODUCTION AND DISEASE, 3., 1982, Tucson.
