GRAEFF, Álvaro  and  TOMAZELLI, Amador. Sources and levels of oils in the feeding of common carp (Cyprinus carpio L.) in the phase of growth. Ciênc. agrotec. [online]. 2007, vol.31, n.5, pp.1545-1551. ISSN 1413-7054.

In this research four lipids sources (cotton, canola, sunflower, corn) and three inclusion levels (1, 3 and 5%) were tested in common carp feeding (Cyprinus carpio L.) incorporated to the diet in the fattening stage. The fishes had start medium weight of 26,6 ± 2,02g and start medium length of 11,2 ± 0,09cm. Diets were formulated inside the criteria to the species and to the production system with ingredients in wich gross protein and energy were kept stable in 28% and 2800kcal of metabolizable energy/kg of ration. Diets were offered in the quantity of 1% of living weight per day readjusted every 30 days in the peletized form. Each experimental parcel comprised six fishes and used an entirely ramdomized design, in factorial (4 sources, 3 levels and 3 repetitions). The data were submitted to variance analisys F test to significant level of 5%, and the mediums compared by the Tukey test. The variables final medium weight, final medium length, feed conversion ratio and survival, showed no significant differences between the tested treatments (P>0,05). Based on the collected data, all sources and lipids levels used are efficient in the feeding. Thus, the one with lower economical value should preferably be used.
