Semen collection and artificial insemination have not yet been fully developed in the alpaca. Thus, we collected semen from 7 males suing a modified artificial vagina placed inside a dummy. Forty adult female alpacas, previously induced to ovulate with hCG, were artificially inseminated with fresh undiluted semen by laparoscopy or by cervix. The Chi-square test was used to determine differences in the fertility rate of the 2 insemination methods. The mean duration of copulation, semen volume, sperm concentration and the percentages of live spermatozoa and normal spermatozoa were 21.6 rain, 1.9 ml. 147,500/mm3, 69.6% and 75.9%, respectively. There were 6.7% abnormal heads, 12.3% abnormal tails and 3.8% cytoplasmic droplets. The consistency of semen was viscous and formed a coagulum. The pH was 7.2, and the semen was milky white in color. The duration of copulation was comparable to natural copulation, and semen characteristics reflected those of the natural ejaculate. The percentage of pregnancy was 68%, with no differences due to method of semen deposition (laparoscopy, 67%; cervix, 73%).
