Abstract

Egg-yolk antibodies (IgY) against somatostatin-14 (anti-SST-14) were evaluated as orally administered, growth promotants in gastric rainbow trout (Oncorhynchus mykiss) and agastric common carp (Cyprinus carpio) in an 8-week feeding trial. Feeding groups were compared with fish which did not receive anti-SST-14 IgY. Growth responses and IgY plasma contents of the blood were assessed. In contrast to rainbow trout, oral anti-SST-14 addition to carp significantly improved protein efficiency ratio (PER, 1.02 ± 0.04) and protein productive value (PPV, 26.7 ± 0.91) after 56 days (P < 0.05) compared to the negative control (PER = 0.91 ± 0.02; PPV = 22.9 ± 0.66). IgY was undetectable in plasma of rainbow trout after oral administration, indicating that gastric degradation of the fed IgY makes this application route for growth promotion in gastric trout challenging.
