The success of an artificial insemination program in ostriches is highly dependent on the yield of viable semen. We, therefore, tested the effect of collection method (Massage, dummy or teaser) on semen quality of male ostriches. Male and female ostriches selected for training were from a breeding flock consisting of 90 adult ostriches (3 to 7 years old). The males used in training for massage, dummy or teaser were nine with 3 males for each method. Semen characteristics were evaluated fortnightly for three consecutive months from all males involved in all semen collection methods. Semen quality traits involved in this study were ejaculate volume, sperm concentration, and total number of spermatozoa, mass motility, individual motility and percentages of dead spermatozoa, abnormal spermatozoa and abnormal acrosomes. Results revealed that using teaser female method for collect the semen from male ostriches recorded the highest values (p ≤ 0.05) of ejaculate volume, spermatozoa concentration, total number of spermatozoa, mass motility, and individual motility and the lowest values (p ≤ 0.05) of percentages of dead spermatozoa, abnormal spermatozoa and abnormal acrosomes during all periods of experiment and as regards the total means of these traits followed by the results of dummy method while massage method recorded the lowest values for these traits. In conclusion, in the ostrich, collecting semen during mating (teaser or dummy) appears to yield better quality of semen than when the manual massage is used. The teaser and dummy methods are reliable, yield quality ejaculates and give reproducible results.
