Dietary Energy: Protein Ratios and Their Impact on Juvenile Nile Tilapia Growth in Mixed Feeding Approaches
To guarantee the sustainability of aquaculture, feeding practices must be evaluated. In this research, two diets were given to young Nile tilapia with varying Energy: Protein (E: P) ratios (10.3 and 9.6 kcal of digestible energy per gram of crude protein). Economic factors, whole-body composition, hepatic steatosis, feed, growth, and nutrient consumption were assessed in the fish. The fish's uniformity, feed consumption, feed conversion ratio, growth, and survival were unaffected by the treatments. Nile tilapia juveniles fed a diet containing 10.3 kcal DE/g CP during a seven-day period saw lower feed costs (P>0.05 per biomass or 1,000 units generated). The feeding protocols increased the amount of the 10.3 kcal DE/g CP meal consumed, which reduced (P=0.055) the contribution of the ether extract to fish weight gain. The whole-body lipid levels of fish showed a similar pattern. Fish from various treatments had comparable body indices (P>0.05). Nile tilapia juveniles perform productively when given a weekly feeding program that combines meals with various E: P ratios.
