| Abstract | ||||
| Twenty two Baladi bucks were divided into 4 groups; the first group injected (i.m) with saline and kept as control; the second group injected with sodium selenite; the third group injected with vitamin E acetate and the fourth group simultaneously injected with both selenium and vitamin E acetate. Injections were given twice weekly for two months. Semen and blood samples were collected weekly. Additional blood samples were collected every half an hour for 4 hours before and after the experiment. Recording of the reaction time, complete semen picture, electrophoretic and immunogenetic analyses of seminal plasma, and radioimmunoassy of plasma testosterone levels were carried out. Results showed that administration of selenium And/or vitamin E improved sexual desire as indi- cated by reduction of the reaction time. Also, se- men characteristics were improved as monitored by increased sperm cell concentration, increased percent of alive sperm and decreased sperm ab- normalities, and acrosomal damage. Plasma tes- tosterone levels showed noticeable increase in comparison to pre-injections levels. These chang- es were more obvious with the advance of time and in bucks injected with selenium and vitamin E. Seminal plasma proteins of Baladi bucks con- tained 15 polymorphic genetic markers, which are controlled by Fo2.
