Prophylactic use of antibiotics in animal production is being banned or restricted by many countries. A potential substitute for antibiotic growth promoters in aquafeeds is organic acids, which are the focus of much research and commercial interest.
In a study, tilapia were fed fish oil- or vegetable oil-based diets for five months, then switched to a fish oil finishing diet for three months. Growth and feeding efficiencies were not significantly compromised.
In a trial, a novel dietary vegetable oil blend was able to totally replace fish oil in tilapia diets without negatively impacting growth performance.
In studies, the physical and sensory qualities of fillets from tilapia fed diets with 100 percent substitution of fish oil with various palm oil fractions were generally not affected by the change of dietary oil source.
Dietary organic acids can exert antimicrobial effects and benefit growth, nutrient utilization and other health parameters in tilapia.
In a study of the effects of interaction between genotype and dietary protein levels on fish performance, GIFT tilapia had greater growth than red hybrids fed diets with equal or higher protein levels.
Vitamin E is a required element in tilapia diets influenced by dietary lipid levels. A 5 percent lipid diet is sufficient to maintain immune responses and healthy reproduction.
Palm distillate could be an effective substitute for fish oils in catfish diets. It is is a rich source of vitamin E and natural antioxidants.
