Summary: The concept of optimizing growth performance and supporting fish health through precise amino acid (AA) nutrition is well-accepted in current Nile tilapia farming. Balanced AAs can contribute to accurately implementing the Precision Nutrition concept and may help assess the economic dimension of the aquaculture system. This review aims to consolidate the relevant published data exploring the amino acid (AA) requirements of Nile tilapia and to reach a new set of recommendations based on those data.

Summary: The study explored the ideal stocking proportion based on animal size for tilapia and tadpole polyculture, with adjusted initial sizes of the species leading to significant differences in results. The best outcomes were achieved with a 12.5% tilapia + 87.5% tadpole polyculture and tadpole monoculture, emphasizing the importance of suitable stocking proportions for successful aquaculture.

Summary: The indoor feeding trial aimed to optimize the amino acid profile of GIFT diet by utilizing the AA deletion method. Different diets were formulated, and supplementation of crystalline AAs showed effects on growth performance and feed utilization of juvenile GIFT tilapia. The EAA pattern associated with -Trp diet was considered optimal for maximum growth and feed efficiency.

Summary: This study investigated the effects of replacing soybean meal with yellow mealworm meal at different proportions on the flesh quality of Nile tilapia. The results showed that when the replacement ratio reached 30% and 45%, the muscle protein and lipid content significantly decreased. The hardness, gumminess, and proportion of thin myofibers in the fillets also increased in the 45% replacement group.

Summary: This study aimed to investigate whether xylanase can alleviate the adverse effects on the gut barrier induced by soybean meal in Nile tilapia and to explore the possible mechanism. The results showed that dietary xylanase improved intestinal morphology and decreased the concentration of lipopolysaccharide (LPS) in serum by inhibiting the perk/atf4 signaling pathway and up-regulating the expression of mucin2 (MUC2), which enhanced the gut barrier function of Nile tilapia.

Summary: Commercially produced black soldier flies have potential as a fish meal substitute, especially when utilizing agricultural by-products and waste. Different substrates used for the cultivation of the flies significantly affect their growth and meal quality, but when incorporated in isonitrogenous and isocaloric diets, there were no significant differences in the growth performance of the fish.

Summary: This study evaluated the potential of crambe meal as a plant protein source in fish diets. Results showed that crambe meal has good digestibility of protein and amino acids for Nile tilapia. However, anti-nutritional factors present in untreated crambe meal interfere with the growth and nutrient utilization of fish.

Summary: This study aimed to investigate the dose tolerance of enzymatically degraded feather meal (EFM) in the diet and the effect of two-stage fermented feather meal on the growth performance and amino acid digestibility of broilers. The results showed that dietary inclusion of more than 15% EFM had a negative impact on growth performance, while the inclusion of Bacillius subtilis var. natto N21 + S. cerevisiae Y10 fermented EFM improved amino acid digestibility and broiler growth performance.

Summary: This study aimed to evaluate the effects of different feeds on the performance of lactating dairy cows. The results showed that increasing the content of rumen undegradable protein (RUP) in the feed can improve the intake and milk yield of cows in mid-lactation. However, the effects of different feeds on the performance of dairy cows were not significant.

Summary: A feeding trial examined the effects of fermented soybean meal with Bacillus subtilis bacteria on Nile tilapia fingerlings. The results showed that bacterial fermentation increased the protein content of soybean meal. Using fermented soybean meal as the sole protein source in fish diets led to a decrease in growth rate and feed utilization, but combining it with corn gluten and/or methionine amino acid improved fish performance.

Summary: This study evaluated the effects of dietary supplementation with L-carnitine on growth performance, gut and muscle histological parameters, blood hematology, plasma biochemical parameters, and antioxidant enzymes in Nile tilapia juveniles. Results showed that supplementation with L-carnitine improved growth performance and reduced lipid content in the filet, while also increasing the activity of the enzyme catalase in the liver. Different inclusion levels of L-carnitine had varying effects on weight gain, fat deposition, and triacylglycerol in the fish.

Summary: This study investigated how metabolite analysis could explain differences in tissue composition and size in fish from different habitats. The results show that nutrition-related blood metabolite ratios are useful in understanding underlying metabolic events leading to habitat-dependent growth differences in fish.

Summary: Poorly digestible proteins can lead to increased protein fermentation and the production of harmful metabolites in the ceca of broilers. In this study, a model was developed to create a contrast in protein fermentation by increasing the prececal flow of protein within ingredients. The results showed that toasting dRSM is a suitable model to increase protein flows into the hind-gut and evaluate the effects of protein fermentation.

Summary: Research showed that feed frequency does not significantly impact growth performance under biofloc conditions, but FF2 and FF5 groups had the best feed conversion and protein efficiency ratios. Different feeding frequencies also influenced the composition of biofloc and the abundance of zooplankton.

Summary: A 70-day experiment was conducted to evaluate the operation of a biofloc system with no carbon addition in Nile tilapia cultivation. The results showed that using a low protein-high lipid diet without carbon addition can improve water quality, reduce environmental impact, decrease dietary costs, with limited effect on fish performance.
