Abstract The present study was carried out at the Poultry Research Farm, Department of Poultry Production, Faculty of Agriculture, Shibin El- Kom, Minufiya University . The experiment was extended from 2008, to 2009, in order to investigate the effect of some factors ( sex, antigen type and antigen administration route ) on immune response and their relation to some blood constituents (total proteins , albumin, globulin , RBCs count , WBCs count and hematocrit values before and after separation ) , and some semen characteristics ( semen volume , percentage of sperm motility , hydrogen ion concentration (PH ) , percentage of abnormal and live sperms ) . A total of 243 (121 males and 122 females ) individuals of Norfa chickens were divided into two groups according to the antigen type. The first group ( 60 males and 61 females ) was injected with sheep red blood cells ( SRBCs ) whereas, the second group (61 males and 61 females ) was injected with bovine serum albumin (BSA). Each group was subdivided- according to the antigen administration route- into two subgroup : The first subgroup ( 30 males and 31 females ) was injected with ( SRBCs ), and (31 males and 30 females) was injected with ( BSA ) using the intravenous (IV) administration route. While, the second subgroup ( 30 males and 30 females) was injected with (SRBCs), and ( 30 males and 31 females ) was injected with ( BSA ) using the intramuscular administration . |
