Sažetak
The effects of different forms of vitamin C and soybean lecithin on growth performance, feed utilization and body composition of brown bullhead (Ameiurus nebulosus, Lesuer 1819) fingerlings were being evaluated during a 9-week growth trial. A special interest was to investigate a possible combined effect of these two nutritional components. The diets used in the experiment contained three forms of vitamin C: crystallized ascorbic acid (AA), encapsulated L-ascorbic acid (CC) and Ca-L-threonate (Ca) (100 mg/kg). We also used these forms of vitamin C in combination with soybean lecithin (CCL, AAL, CaL). Besides control diet (K), one more diet was supplemented only with soybean lecithin (L). One-hundred-ninety-two brown bullhead of about 45 g initial body weight was randomly divided in 24 experimental tanks (115 liters each). Testing conditions included 8 fish per tank, with triplicate tanks for treatment. All diets with supplemented components resulted in higher final weight. SGRw and FCR were significantly higher with encapsulated vitamin C diets (CC, CCL), followed by enriched ascorbic acid diets (AA, AAL). Vitamin C and lecithin supplementation positively influenced number of erythrocytes, hematocrit, and total protein. Vitamin C content of muscle and liver tissue was not uniform and was significantly higher in AAL, CCL, CC and AA feeding groups. The fatty acids profile of muscle and liver tissue showed that phospholipids from soybean lecithin and vitamin C diets enhanced the quality of edible part of the fish body. Combine supplementation of vitamin C and soy lecithin indicated positive production effects in the 9-week growth stimulation trial. On the light of the results obtained, we recommend the diet enriched with encapsulated L-ascorbic acid and lecithin to be used in aquafeed for the species investigated.
