abstract
The data obtained in the present investigations were described being of two kinds.

(1) Number of the chicks hatched from TP 1.0 mg injected eggs was observed in an average small number compared with control. Bursa size and weight of chicks of TP treatment were observed to show remarkable reduction in the same way of previous report.

(2) Smaller bursa chicks in TP treatment showed higher mortality rate than normal chicks at injection of Salmonella senftenberg at 14 days of age after haching. From the results of this present study, it is presumed that the bursa of Fabricius is concerned with antibody reproduction in young chicks. The spleen of chicks that received the injection of S. senftenberg observed remarkably large weight as compared with to that of control chicks.
