“…The aquafeed industry usually supplements Nile tilapia feed with excess trace minerals since the cost of inorganic minerals is relatively low (Nguyen et al., 2019). Such supplementation also counteracts antinutrients, such as phytate, present in practical ingredients, which can hinder trace mineral absorption.…”

Different levels of organic trace minerals in diets for Nile tilapia juveniles alter gut characteristics and body composition, but not growth

et al. 2020

Thirty groups of twenty juveniles each of Nile tilapia (Oreochromis niloticus, initial average weight 23.93 ± 0.80 g) were fed diets containing increasing amounts (0%, 25%, 50%, 75%, and 100% of levels used by the tilapia feed industry) of organic trace mineral (Fe, Zn, Mn, Cu, Se) supplementation for 56 days. Growth was not affected by the dose of mineral supplementation. However, body protein increased in fish fed intermediate doses of organic minerals, reaching a maximum at 40.44% supplementation. Doses >50% showed mild damage to the intestinal tissue. Body Fe, Zn and Cu deposition were highest at 28.32%, 24.43% and 78.45% supplementation, respectively. Tilapia could modulate intestinal morphology when fed different doses of organic minerals. As the supplementation doses increased, hemosiderin staining increased in the distal intestine and total body Fe content, indicating that the distal region of the intestine plays an important role in iron excretion by tilapia. Supplementation of organic trace minerals at intermediate doses does not harm Nile tilapia growth, but excessive trace mineral supplementation can impair body protein retention and promote histological alterations in the gut.

“…In Nile tilapia, organic dietary sources significantly promoted higher body accumulation of Se when compared to inorganic sources (Nguyen et al., 2019; Vinchira, 2014). However, inorganic sources of Zn are more bioavailable compared with organic sources (Do Carmo e Sá et al., 2005).…”

“…The optimum Se level in our study was lower than 1.06 mg/kg selenium in the previous report in which non‐purified diets with plant ingredients were used (Lee et al, ). It was possible that plant ingredients could decrease the bioavailability of Se and increase the true requirement of optimal Se in fish (Nguyen et al, ). Other reasons included that the feeding rate of 5% in this study was different from that (3%–4%, Lee et al, ), or other factors such as differences of endogenous Se loss (Shearer, ).…”

“…In many studies, the normal weight gains were about 350%-500% (Xu et al, 2018;Wang et al, 2017) for large size of fish and even higher (1, 000%-1,200%) in small size of fish under the laboratory conditions (Gan et al, 2016;Xu et al, 2018). The dietary ingredients used in the study (Lee et al, 2016) were plants which are generally considered poor sources of minerals and may contain antagonists such as phytic acid (phytate) that are known to reduce bioavailability of minerals (Nguyen, Kubitza, Salem, Hanson, & Davis, 2019). Bioavailability of an element may be the main factor affecting element requirement of an animal, because it may vary by several orders of magnitude (Dashti & Bengmark, 1985).…”

“…Bioavailability of an element may be the main factor affecting element requirement of an animal, because it may vary by several orders of magnitude (Dashti & Bengmark, ). Several studies (Nguyen et al, ) using practical basal diet with only plant ingredients showed that there were no significant effects of dietary Se levels on growth performance, survival rate and whole body proximate composition of Nile tilapia, even at dosage of 4.0 times of requirement as stated in NRC (). Thus, further investigation of essential and optimal Se requirement in Nile tilapia is necessary.…”

Optimum selenium requirement of juvenile Nile tilapia, Oreochromis niloticus

et al. 2019

A feeding experiment was conducted to determine the optimum selenium requirement in juvenile Nile tilapia. Each of six purified diets with Se‐methionine levels at 0.05, 0.21, 0.41, 0.57, 0.79 and 1.00 mg/kg was assayed in triplicate with initial body weight of 3.00 ± 0.01 g for 8 weeks. The growth of fish was obviously increased when the dietary Se was less than 0.57 mg/kg diet and reached a plateau when the dietary Se was ≥0.57 mg/kg. Serum and hepatopancreatic glutathione peroxidase (GPx) activity increased markedly when the dietary Se was less than 0.57 mg/kg, but then decreased when the dietary Se was higher than 0.57 mg/kg. The malondialdehyde contents in hepatopancreas were significantly decreased when the dietary Se was higher than 0.79 mg/kg. No significant differences were observed in hepatopancreatic total antioxidant capability (T‐AOC) among the groups (p > .05). The results of this study indicated that Se addition as Se‐methionine was essential, while both the deficiency and excess levels of dietary Se would cause negative effects on growth or antioxidant capability in juvenile Nile tilapia. Based on broken‐line regression of WG and piecewise regression of liver GPx, the optimum requirement of Se for juvenile Nile tilapia is 0.57 mg/kg diet.

Metal–amino acid complexes (Zn, Se, Cu, Fe, and Mn) enhance immune response, antioxidant capacity, liver function enzymes, and expression of cytokine genes in Nile Tilapia reared under field conditions

An 80‐day trial was carried out to evaluate the effects of replacing dietary inorganic trace minerals (ITM), with metal‐amino acid complexes (MAAC) on immune response, antioxidant capacity, and expression of cytokines genes of Nile tilapia (Oreochromis niloticus) reared in in‐pond hapas under field conditions. Quadruplicate groups of fish (93.65± 1.05 g average initial body weight ± SE) were stocked in 2‐m3 hapas fixed in a fish pond, at a density of 30 fish m‐3 (60 fish per hapa). Five isocaloric (17 MJ kg‐1), isonitrogenous (30% CP) extruded tilapia diets were produced, containing 0 (control), 25%, 50%, 75%, and 100% MAAC (Zn, Se, Cu, Fe, and Mn) as a replacement of the inorganic mineral premix. Replacement of ITM with MAAC premix enhanced the immune and antioxidant responses of Nile tilapia. The activities of lysozyme (LSZ) (96.71 U ml‐1 ± 0.69 – 120.83±1.43 U ml‐1), respiratory burst (0.54±0.08 mg ml‐1 – 3.61±0.20 mg ml‐1), alternative complement (ACH50) (34.49±56.96 % hem ml‐1– 56.96±0.79 % hem ml‐1), phagocytic cells (PA) (5.30±0.52% – 17.27±0.82%), phenoloxidase (PO) (34.96±0.96% – 54.68±0.92%), superoxide dismutase (SOD) (45.15±0.88% – 65.92±0.85%), glutathione peroxidase (GPx) (0.22±0.01 nM min‐1 mg‐1 – 1.94±0.09 nM min‐1 mg‐1), and liver function enzymes were all significantly improved (P<0.01, except for PA and GPx where P<0.05) with increasing supplemental MAAC up to 50% substitution level and decreased with further increase in MAAC to 75% and 100% levels. The expression of cytokine genes (mRNA abundance), including interferon (IFN‐γ) (2.67±0.03 – 4.62±0.08), tumor necrosis factor (TNF‐α) (2.96±0.05 – 6.73±0.05), serum alkaline phosphatase (AKP) (0.51±0.02 – 1.72±0.02), the integrated microbial genomes (IgM‐2) (22.51±0.36 ‐ 38.48±0.03) and transforming growth factor (TGF‐β) (1.84±0.02 – 7.76±0.02) genes was significantly upregulated in fish fed on MAAC–supplemented diets (P<0.05) compared with the control group. The 50% MAAC level produced the highest upregulation of these genes, whereas gene expression decreased with increasing dietary MAAC levels to 75% and 100%.
