Résumé

Basic objective of this research was to ascertain the effect of long photoperiodic (18L:6D) and
the treatment prolactin concentration of 10 and 20 ng / ml / of bird / 3 days in the breeding pigeons
(Columba livia domestica), and the level of concentration of prolactin and thyroxin and testosterone,
proteins and sugars in the plasma male domestic pigeon. Where the results obtained showed that along
the reproductive or sexual activity, from 5 to 6 weeks in the photoperiodic long (18L: 6D), for the control
lost sight (blind)of, either the treatment focus yen different prolactin 10 ng / ml / of a bird / 3 days has a
significant impact on the lower (P < 0.05) the growth of male sex glands while treatment concentration
20 ng / ml / of a bird / 3 days of prolactin keep birds treatment in the dormant days for the duration of
sexual experience It also demonstrated the importance of the results of research for the article analyses
hormonal male blood plasma in the pigeon, there are very low or mental function (P<0.01) in the
decrease of concentration in plasma prolactin bird, a blind and control in week 4 and 8 compared treated
of 10 and 20 ng / ml / of a bird / 3 days as for the plasma concentration thyroxin when male pigeon, the
control, a lost sight is very important to the stability of the opposite treatment of two different doses 10
and 20 ng / ml / of a bird / 3 days are lower (P <0.01) in focus throughout the day experiment as for the
concentration of protein and hormone testosterone are rising significant (P <0.05) in concentration
during the week 6 and 8 for the control and lost sight, as stability in the glucose concentration within
weeks only at the beginning of the experiment was high when brigades lost sight, treated of 20 ng / ml / of
a bird / 3 days.
Key words: Reproduction- Prolactin- Thyroxin- Photopériod- Birds.
