Abstract

Seven experimental diets contain (0, 1, 2, and 3) % of Basil and Ginger oils were used to study their effects on growth performance, survival, feed consumption, body composition and hematological indices on Red tilapia Oreochromis Spp. fingerlings. Sixteen glass aquaria (60x40x40 cm, 96-L capacity) were used, two aquaria per treatment. Ten fish in the same average weight (39.4±0.3 g /fish) were stocked in each aquarium. Fish were fed 3 % of their body weight, twice a day for 45 days.

Higher significantly (P<0.05) was found in final body weight ‘FBW’, weight gain ‘WG’, specific growth rate ‘SGR’, feed conversion ratio ‘FCR’, protein efficiency ratio ‘PER’ and productive protein value ‘PPV’ between gropes of fish were fed diets containing basil and ginger oils and control diet (0.0 % oil). Increasing levels of basil and ginger oils led to enhancing growth, feed conversion ratio and nutrient retention efficiencies. Basil oil diets at different levels led to an increase in growth performance and feed consumption and were better than Ginger oil diets, while ginger oil diets recorded an increase in the number of white blood cells ‘WBC’ compared to the control diet. Diet containing 3 % Basil oil inclusion was superior than other test levels and it recommended to use in Red tilapia diets.
