Penggunaan ragi roti (Saccharomyces cereviciae) secara in situ untuk meningkatkan respon kebal non-spesifik ikan nila (Oreochromis niloticus)
Abstract: The objetive of
research was to examine the effect of yeast cell Saccharomyces cereviciae on
non-specific immune response of nile tilapia, Oreochromis niloticus. Juveniles weighing
31.83 g in average were cultured in five concrete tanks with a density of 30
fish per tank. The fish were fed pellet supplemented with yeast cell at five
different doses (0, 10, 20, 30, 40 g/kg pellet) for three consecutive weeks as
much as 4%/bb/day, twice daily. At the end of feeding, three fish from each
tank were sampled to measure the immune parameters namely total leucocyte count
and phagocytosis activity of phagocyte cells. Research results showed that
after three weeks of feeding, total leucocyte and phagocytosis activity of fish
fed pellet supplemented with yeast cells were significantly different as
compared to those of control fish. The highest total leucocyte and phagocytosis
activity were achieved in fish fed pellet supplemented with 10 g of yeast
cells/kg pellet. It was concluded that the use of yeast cells for three weeks
could enhance the nonspecific immune response of nile tilapia.
