BUYUKCAPAR, H.M.  e  KAMALAK, A.. Raw and heat-treated culban (Vicia peregrina) seed as protein source for mirror carp (Cyprinus carpio) fingerlings. S. Afr. j. anim. sci. [online]. 2006, vol.36, n.4, pp.235-242. ISSN 2221-4062.

An 80-day feeding trial was conducted in a recirculation system aquarium operating at 26 ± 0.3 °C, to evaluate the nutritive value of Vicia peregrina seed as a possible protein source in the diet of mirror carp (Cyprinus carpio) fingerlings. Vicia peregrina seed was included in the diets at different levels, viz. 100, 200, 300 g heat-treated and 100, 200, 300 g raw seed in experimental diets designated A₁, B₁, C₁, A₂, B₂ and C2, respectively. Growth parameters of the fish fed these diets were compared to fish receiving a fish meal and soyabean meal based control diet. On the basis of the specific growth rate (SGR), feed conversion ratio (FCR) and protein efficiency ratio (PER), the control and diets A₁, B₁, C₁ and A₂ were similar and significantly better than diets B₂ and C₂. Fish fed diets B2 and C₂ showed a lower growth performance compared to those fed diets A₁, B₁, C₁ and A₂. Whole body fat content of the fish fed the diets containing the higher levels (>10%) of raw V. peregrina was significantly lower than in fish in the other treatments. Vicia peregrine seed has a potential as an alternative feed ingredient. It can be used without any adverse effects at up to 10% of the diet as a protein source in diets for fingerling mirror carp. However, the seed should be heat-treated if inclusion rates are to exceed 10% of the diet.
