RESPON IMUNOLOGI IKAN NILA GIFT (Oreochromis sp) TERHADAP PROBIOTIK STRAIN A3-51
ABSTRACT: One of the problem
in Tilapia culture is bacterial diseases, such as that caused by Aeromomas hydrophyla.
Diseases management can be conducted by vaccine and antibiotic application.
Probiotic, such as A3-51 offers a better alternative in diseases management
since it has been proven to increase non specific immune respond in some
fishes. The aims of this research were to find out the effect of duration of
probiotic A3-51 application and challenging test on to immunological potency as
indicated by blood profile, number of kidney macrophage and it protection
level.This research was conducted experimentally applying a factorial design
based on RCBD. The tested factors were the duration of probiotic A3-51
application consisted of five levels namely 0 (A), 7 days (B), 14 days (C), 21
days (D), and 28 days (E); and timing of A. hydrophila challenged test
consisted of day 0 (a), 7 (b), 14 (c), 21 (d), and 28 (e).There were 25
combination of treatments with 2 replicates. Each experimental unit consisted
of 5 fishes. Evaluation time points (the date of data collection) were served
as Block. The results showed that duration of probiotic administration and
challenged test were to increased the number of leucocytes, macrophage,
erythrocyte and percentage of leucocytes. The number of leucocytes was raged
from 5,700 to 77,762.5 cells/ml with a maximum number was observed from the
fish given probiotic A3-51 for 14 days the challenged with A. hydrophila on day
14 (C14c14).
