Description A study was conducted for collection and evaluation of emu bird semen. Ten adult male emu birds aged 3 to 4 years were selected and housed individually in a 10' x 50' pen constructed in parallel rows at TANUVAS, Tamilnadu, India. The male birds were selected based on their readiness in accepting human beings without fear. All the birds were housed properly under standard managemental condition. The selected male emus were trained for semen collection by non-teaser method. Out of 10 males, only seven males responded for semen collection. As emu is a seasonal bird, the raw semen was collected from individual emu birds in three different breeding seasons (early, peak and late) and evaluated for macroscopical and microscopical seminal attributes. The overall mean values for volume, pH, mass activity, per cent motility, concentration, per cent live and abnormal spermatozoa were 0.61± 0.02 ml, 7.40 ± 0.03, 3.36 ± 0.08, 74.39 ± 0.99, 2.19 ± 0.05 x 10^9 per ml, 87.40 ± 0.67% and 9.15 ± 0.33\% respectively. This study ensures the possibility of semen collection and facilitated further processing or artificial insemination of semen in early or peak season based on macro scopical and microscopical seminal attributes.
