Abstract
The development and duration of immune protection against Aeromonas hydrophila infections with garlic as immunostimulant in rainbow trout Oncorhynchus mykiss was studied. Rainbow trout fingerlings of 14 g average weight were fed with 0 g (= Control), 0.5 g and 1.0 g of garlic 100 g-1 of feed for 14 days. Physiological factors, biochemical, immunological, hematological parameters and electrolyte indices were evaluated after a further 14, 21 and 28 days before challenge with Aeromonas hydrophila. Fourteen days after the cessation of feeding with garlic, mortality rates of 12 % (relative percent survival [RPS] = 86 %) and 16 % (RPS = 80 %) were recorded in groups which received 0.5 g and 1.0 g of garlic 100 g-1 of feed, respectively, compared to 84 % mortalities in the controls. The corresponding RPS 21 days after ending the feeding regime was 75 % and 68, respectively. One week later, the RPS had dropped to 55% and 46% in the groups fed with 0.5 g and 1.0 g garlic 100 g-1 of feed, respectively.
