Opis

The massive amount of information indicates that plant secondary compounds (Phytochemicals) have many functional and nutritional properties that may have application for animal nutrition and can replace the used of synthetic chemicals. The beneficial effects of phytochemicals include growth activation, immune stimulation, testosterone augmentation and antioxidant characteristics that may help to improve the general physiological condition of fish. Wide range of herbs is available for inclusion in animal diets. Accordingly, this thesis evaluates the effects of new dietary natural phytochemicals (ginseng extract, tribulus extract, and date palm pollen) on pituitary hormones, testosterone and growth performance of Nile tilapia, O. niloticus, fingerlings. Also, the possibility of using phytochemicals in sex reversal in newly hatched tilapia.
