Abstract

The objective of this research is to find the effect of noise stress giving and Newcastle Disease vaccination to the number of lymphocyte cell in chicken's busa of fabricius. On the previous research done by Arimbi (1999), samples that used were 100 Day Old Chick CP 909 strain which is produced by PT. Charoen Phokphand. Those samples divided into 4 group based on the treatment given, each group consist of 25 chicks. The group based on the treatment are Group I (PO) was neither stress or vaccination (S-V -), group 2 (PI) was vaccinated without stress (S-V +), group 3 (P2) was stress without vaccination is+ V -) and last group 4 was either stress and vaccination (S+ V +). Samples were taken on 8 week and they were used are 20 bursa of fabricius organs. Those samples divided into 4 group of treatment, each group consist of four samples. As the research method, sample has been processed became histopathological examination by microscopic evaluation was used to count the number of lymphocyte cell. The result of this research shows the number of last lymphocyte cell in group PI (S-V+) is the highest. That situation related to the vaccination was given. Based on group PO (S-V -), as controller. The number of Iymhpcyte cell in group P2 (S+V-) and P3 (S+V+) have been reduced. This condition caused by continuously stress and it leads into exhaustion phase of the GAS theory, which is stress is no longer adaptable. This condition caused by continuously stress and it leads into exhaustion phase of the GAS theory, which is tress is no longer adaptable. This condition could supress the immune system and cause failure in proliferation and differentiation of lymphocyte cell. And finally the number oflymphocyte cell decreased.
