Abstract
Giant Cichlid (Petenia splendida "RED") is a newly developed species with delicious meat. It grow rapidly when extensive farming. It can grow up to 40 cm with beautiful appearance and bright color with huge market potential. An 8-weeks experiment was conduceted to study the effects of dietary protein, lipid levels and vegetative ingredients replacing fish meal on growth performance of Giant Cichlid (Petenia splendida "RED").
Experiment I: 6 formulated diet with 3 levels of crude protein(CP 45%, 40%, 35%) and 2 levels of crude lipid (CL 8%, 13%) were fed to Giant Cichlid for 8 weeks. The results showed that the best diet with 45% protein and 13% lipid is weight gain 136% and feed efficiency 56%.
Experiment II: the examine the replacement of the fish meal with vegetative ingredients at various levels in practical feeds for Giant Cichlid, C5、C10 and C15,replacing fish meal with corn protein by 5%、10%、15%. After 8 weeks feeding trial, the results showed that the optimal replacement ratio of corn protein is 10%.
Experiment III:Four diets were supplemented with additional 8% lipid with soybean oil and fish oil : C0(3:2) 、L1(soybean oil ) 、soybean oil and fish oil :L2(4:1)、and L3(fish oil). After 8 weeks feeding, the results showed that experiment groups weight gain and feed efficiency were no significantly differences with soybean oil and fish oil : C0(3:2).
