Acute hyposalinity stress in shrimp ponds is a natural occurrence during the rainy season and the provision of functional ingredients that will elicit resistance to this stress is needed. Quillaja saponin (QS), a triterpenoid saponin derived from the bark of Quillaja saponaria, is reported to trigger innate immunity in vitro and in vivo in shrimps. The present study aims to evaluate its potential as growth-promoter and its immune-enhancement effects against salinity stress. Three separate experiments were done: (a) an attractability test; (b) a 30-day feeding trial to determine optimal inclusion of QS; and (3) an acute hyposalinity stress test following feeding the experimental diets. Attractability tests showed that all the Quillaja saponin inclusions significantly attracted more shrimps than the control diet (p |
