Suppression of Stress Responses in Siberian Sturgeon, Acipenser baeri, Juveniles by the Dietary Administration of Bovine Lactoferrin
Abstract A study was performed to investigate the influence of dietary lactoferrin ( LF ) on growth and stress responses of juvenile Siberian sturgeon. Fish were fed six experimental diets (0, 100, 200, 400, 800, and 1600 mg LF /kg diet) for 10 wk. At the end of the experiment, fish were exposed to...
