The use of citrus pulp silage in Diplodus puntazzo nutrition

[EN] Purpose Studying the efect of citrus pulp silage in the growth performance, amino acid retention of sharpsnout sea bream juveniles. Methods Citrus pulp is an energy and protein source that has been used to replace wheat meal in Diplodus puntazzo fngerlings; 96 fsh of 21.5±0.67 g were nourished with two experimental diets for 105 days. The control diet (CON) contained 421.6 g/kg of protein and 22.6 MJ/kg of energy. The citrus pulp diet (CPD) included 442.7 g/kg of protein and 22.02 MJ/ kg of energy. Results At the end of this trial, the CPD did not afect the growth parameters, but the feed efciency values exhibited statistically signifcant diferences, with those fsh fed the CPD having higher values, possibly due to the presence of limonene in the diet. The CPD also resulted in a reduction in amino acid (AA) content due to the protein being bound to fbre; this consequence did not afect the fnal fsh AA profle. For AA retention, only arginine displayed signifcant diferences, although the rest of the AAs also showed efects of AA reduction from the CPD. Conclusion Citrus pulp silage can be used in D. puntazzo feeding, without adverse in the growth performance and the amino acid profle, although it did cause a reduction in feed efciencyNogales Mérida, S.; Tomas-Vidal, A.; Jover Cerda, M.; Sánchez Lozano, NB.; Velazco Vargas, JL.; Martínez-Llorens, S.
