| Abstract | ||||
| The extruded lupin seed meal (Lup < /em>inus a/bus) was used as alternative protein source to partially replace fish meal in feeding of Sp < /em>arus aurata. Four experimental diets were formulated to contain 40.68% ±0.12 CP. Diet 1, without lupin seed meal and considered to be the control, where L 10, L20 and L30, lupin seed meal was incorporated at 10,20 and 30%, respectively. Sixty fingerlings of Sparus aurata with an initial body we~ht of S.45±O.05g were distributed at random in twelve fiber glass tanks (each of1 m ). The fish were fed 3% of their total body weight and the diets were offered at two times/day. Growth performance of fish showed a significance differences (P<0.05) between treatments. The highest performance was recorded with the fish fed 20% lupin seed meal (L20), followed with lesser extant by the control and L 10 diets, respectively. However, the least performance was recorded with 30% incorporation level of lupin seed meal (L30). The carcass composition of fish were not affected by the incorporation level of lupin. The digestibility coefficients of the experimental diets showed a good utilization for protein in all tested diets. However, the carbohydrate digestibility coefficients recorded inferior results. On the other hand, the blood characteristics of fish (Hematocrite, Hemoglobin and plasma protein content) not differently by lupin seed level in the diets. The results of the present trial concluded that, the lupin seed meal can be utilized at level of 20% in feeding of Sparus aurata, without adversely effects on growth performance, digestibility coefficient and blood characteristics. | ||||
