Crossing between selected Japanese quail birds lines based on body measurements and its effect on fertility and hatchability
AbstractThe present study was carried out in Poultry Research Station of the Animal Resource Department / Office of Agricultural Research / Ministry of Agriculture for the period from 23/03/2014 to 06/11/2014. The study was aimed to assess the influence of crossing between quail selected lines on based body measurements with respect fertility, hatchability, a basic quail bevy consists of 203 females, and 92 males were used as the foundation stock. In the first generation 1366 birds were obtained and 948 birds in the second generation, as the basis selected stock a according to selection index on body weight and Breast (length, depth and width Breast) individually and by repeating twice each group, either on the first generation (F1) selection conducted according to the measurement of body weight for three groups and was at the age of 6 weeks 182.25 and 165.50 and 159.44 of the line high body weight of AA and population mean body weight of line BB and line low body weight of CC to relay, and with three replicates for each group, then the mating system application procedure was done between three groups selected individually for the body weight recipe to get the second-generation which consist of 18- combination by repeating each combination twice, Results obtained showed there were the fertility rate line of parents A in the first generation(F1) showed significant differences compared with the Line B, In the second generation(F2) observed the fertility rate of maternal line recorded significant differences were compared the Line A with line B, Also been found for hatchability percentage from total eggs of maternal lines in the first generation (F1) significant differences were of the line A compared with the line B and Line C, to observe at for hatchability percentage from fertility eggs maternal lines in the first generation(F1) significant differences were Line A compared with the line B and the line C.
