An experiment was designed to test the effectiveness of deep-frozen Angora goat semen after insemination. Oestrous periods of Angora goat does were synchronized with the progesterone sponge technique and the does were inseminated with pelleted deep-frozen semen at oestrus. Two inseminations were carried out 12 h apart commencing 12 h after the first signs of heat were detected. Kidding percentages of the does were compared after natural mating and artificial insemination with fresh or deep-frozen semen. The results achieved were 76,7%; 90% and 34,8% respectively. Although a significantly lower kidding percentage was obtained when frozen semen was used, these results warrant further investigation of techniques for freezing goat semen.
