Sixteen sexually matured (12 months old) healthy male Turkeys were used to determine the effect of Gonadotrophin (Diclair®) on kidney function, weight gain and serum protein values. The Turkeys were divided into 4 treatment groups, identified as T1 (control) administered with 1.00ml physiological saline (0.00 i.u Diclair®), T2 , administered with 13.50 i.u Diclair®, T3,administered with 27.00i.u Dicliar®T4, administered with 40.50 i.u Dicliar(R), with one Turkey per replicate in a completely Randomized Design (CRD). The injections were divided into 3 doses each and administered intramuscularly in the thigh for three consecutive days. Blood was collected one week after Diclair® administration. Four Turkeys were randomly selected fro-m each treatment groupand bled to collect blood for blood chemistry analysis. The Turkey were weighed every week for five weeks and their weight recorded. The result showed that there were significant differences (P< 0.05) among the treatment groups in all parameters for kidney function test: chronicle, potassium, sodium, bicarbonate expect creatinine which was similar (p > 0.05) among the treatment groups. The results further showed that there were no significant differences (p > 0.05) among the treatment groups in initial body weight. However, there were significant differences (P< 0.05) among the treatment groups in final body weight and weight gain. Similarly there were significant differences (P< 0.05) among the treatment groups in all the serum protein values measure: albumin, globulin, serum total protein as well as albumin/globulin ratio. The results of the study showed that Diclair enhanced kidney function and weight gain without any deleterious effects on serum protein values of the male Turkeys.
