Separate in four groups randomly, within that, one group is set as control group and other three groups were inoculated 0.1ml, 0.2ml and 0.3ml, respectively. Record the performance and mortability for comparision. The trial indicated that there was significant difference among three groups, 0.2ml group showing higher effect and 0.3ml group being lower. Thus, it is concluded that dosage clearly affected the efficiency of vaccination. In this context, the reason is also well discussed.
