| Summary: | Daily requirements for energy and protein were determined in growing Litopenaeus vannamei as the sum ofrequirements for maintenance and growth. The requirement of digestible energy for maintenance was calculated tobe DEmaint = 345 J per g body mass and for digestible protein DPmaint = 7.5mg per g shrimp per day. The partialefficiencies of utilization for growth above maintenance were 0.31 and 0.44 for digestible energy and digestibleprotein respectively. The daily weight gain (g) as a function of body weight (g) could be described at a temperatureof 280C by the following equation: y = 0.05 × BW (g)0.582. The composition of the gain was determined by analyzingwhole shrimp ranging from 1 to 35g. The energy and protein contents were independent upon shrimp weight andwere on average 4.844 kJ g-1 and 172 mg g-1 body mass respectively.Based on those results, feeds can be formulated for growing Litopenaeus vannamei with optimal energy to proteinratio during the entire grow-out period to increase retention efficiency and reduce excretion of nutrients |
