ABSTRACT
Morphological characteristics of turkey Meleagris gallopavo semen were recorded and hatchability percentages of the artificially inseminated hens were assessed. To study the effect of natural mating on hatchability 15 (3♂, 12♀) M. gallopavo were randomly selected, were kept separately and were allowed to mate through stud mating. For artificial insemination, male (n = 3) and female (n = 12) birds were kept separately. Semen of the male birds was collected on weekly basis to record morphological characteristics and to inseminate the female birds. Mean abnormal spermatozoa rate was 14.61±1.61% with most common acrosome defects 39.67±3.80 % followed by defects in mid-piece 29.61±0.24%, head defects 10.15±1.21% and tail defects 20.57±1.97%. Laid eggs were collected, stored and were incubated for hatching. Hatchability percentage in artificially inseminated hens was greater 88.30% than natural mating 80.51%.
