Abstract
ABSTRACT
Primary objective of this research is to determine the effect of long photoperiodic (18L: 6D) and/or treatment with prolactin hormone at 10 and 20 ng / i.m. / bird /3 days on the reproductive cycle of the male pigeons (Columba livia domestica) and the levels of prolactin, testosterone, thyroxine, proteins and glucose. The obtained results showed that: Increase the reproductive cycle or sexual activity length from 5 to 6 weeks after exposure to the long photoperiod (18L: 6D) for the control and lost sight groups, whereas treated birds with 10 ng prolactin showed a significant decrease (P <0.05) in testes growth. Treatment of pigeon with 20 ng prolactin kept birds in a refractory phase of sexual activity along the experimental period. There was a significant decline (P <0.01) in the plasma prolactin level in the lost sight birds in the week 4 and 6 relative to groups treated with 10 and 20 ng prolactin (i.m./bird/3days). Also, the levels of thyroxin, testosterone and total protein recorded a marked drop in the groups treated with 10 and 20 ng prolactin throughout experimental period in comparison to control and blind groups. Glucose levels were decreased significantly (P <0.05) in control and lost sight birds in the 4th week comparative to groups treated with 10 and 20 ng prolactin. Also, glucose levels were reduced in the 4 groups in the 6th week relative to beginning of experiment.
Key words: Reproduction; Prolactin; Thyroxin; testosterone; Photoperiod; Pigeons.
