Abstract— Sixteen sexually matured (12 months old) healthy male turkeys were used to determine the effect of Gonadotrophin (Diclair ®) on semen characteristics, body conformation and hormonal profile. The turkeys were divided into 4 treatment groups of 4 turkeys per group, identified as T1 (control), and ministered with 1.00ml physiological saline, T2, administered with 13.50i.u Diclair®, T3, administered with 27.00 i.u Diclair® and T4, administered with 40.50i.u Diclair®, with one turkey per replicate in a completely Randomized Design (CRD). The injections were divided into three doses each and administered intramuscularly in the thigh for three consecutive days. Semen was collected one week after Diclair® administration, twice a week for 4 weeks by the abdominal massage and manipulation of the cloaca method. Four cocks were randomly selected from each treatment group and bled one week after Diclair® injections to collect blood for hormonal profile evaluation. 30 days after Diclair® injection, parameters for body confirmation were measured. The results showed that there were significant differences (P < 0.05) among the treatment groups in all the parameters for semen characteristics except semen pH and semen volume which were similar (P > 0.05) among the treatment groups. The results further showed that there were significant differences (P < 0.05) among the treatment groups in all the parameters for body confirmation: wing length, neck length, shank length, body length, beak length, thigh length, keel length, chest circumference and tail length. Similarly, the results showed that there were significant differences (P < 0.05) among the treatment groups in follicle stimulating hormones (FSH), luteinizing hormone (LH) and testosterone levels. The results of this study suggest that Diclair® improved semen quality, body confirmation and was not detrimental to the hormonal profile of the turkeys.
