Taurine supplementation enhances the replacement level of fishmeal by soybean concentrate in diets of juvenile Pacific white shrimp ( Litopenaeus vannamei Boone, 1931)

Abstract

This study aimed to evaluate the effects with and without 1000 mg taurine supplement and five levels (0%, 25%, 50%, 75% and 100%) of fishmeal (FM) replaced by soybean concentrate (SBC) in the diet on white shrimp. After 8-weeks' feeding, the results showed that the taurine supplement significantly affected final weight (FW), weight gain (WG%), feed intake (FI%), glutamate-pyruvate transaminase (GPT), triglyceride and cholesterol in plasma and glutathione peroxidase (GPx) in haemocytes of white shrimp. There is no significant effect on growth performance, haemolymph parameters and immune responses up to 50% but significant effect at 75 and 100% FM replacement by SBC. Generally, the taurine concentration in plasma, whole body and muscle decreased with an increase of FM replacement in the diets, but they were not significantly affected by 1000 mg taurine supplement in diets. In conclusion, a dietary supplement of taurine at 1000 mg/kg diets significantly enhanced WG of white shrimp after the SBC replacing FM up to a higher than 50% level. FM can be replaced by SBC up to 50% without a significant negative effect on growth performance, haemolymph parameters and immune responses.

Can dietary with a taurine supplement improve lipid utilization, growth performance, haemolymph parameters and immune responses of white shrimp ( Litopenaeus vannamei )?

“…The increasing dietary lipid increased the HSI of white shrimp, which was similar to previous studies of white shrimp that HSI values increased gradually with increasing dietary lipid level (Hu et al, 2008;Xu et al, 2018), but the taurine supplement did not significantly affect the HSI of white shrimp in this study, similar to a previous study on white shrimp with taurine supplement (To & Liou, 2021).…”

“…In this study, increases in dietary lipids and taurine supplements resulted in significant increases in lipid contents of whole body and muscle of white shrimp, showing excess dietary lipids deposited in the tissue, which was similar to the previous studies of dietary lipid levels on white shrimp (Hu et al, 2008;Liu et al, 2018) and taurine supplements in the diet on white shrimp (To & Liou, 2021;Yue et al, 2013). We did not analyse lipid content in the hepatopancreas of white shrimp in the present study, but a previous study reported that lipid content in the whole body was related to the HSI value, which meant that the high HSI value of white shrimp recorded high lipid content in the whole body because most lipids of white shrimp were stored in the hepatopancreas (Xu et al, 2018).…”

“…El-Sayed, 2014; Salze & Davis, 2015). The finding of this study was similar to the studies describing the marked improvements in the growth performance when fed taurine supplement at 0.1% in the low fishmeal or no fishmeal in diets for white shrimp (To & Liou, 2021), 0.17% for white shrimp (Yue et al, 2013) and 0.4% for tiger shrimp (Shiau & Chou, 1994). An inhibitory effect on WG% and FE was observed in the three lipid content groups as compared to taurine supplementation 0.6% with 0.2% groups.…”

“…Groups with lower lipid (5%) consistently had higher whole-body and muscle protein concentrations, which may be due to the compensational decrease in whole-body lipid (Xu et al, 2018). Besides that, the taurine supplement in the diets did not influence moisture and crude protein in whole-body composition, which was in agreement with those previously reported in the whole-body composition of tiger shrimp (Shiau & Chou, 1994) and white shrimp fed diets with taurine supplements (To & Liou, 2021;Yue et al, 2013). et al, 2012).…”

“…Indeed, taurine has been considered required for several marine fish (Lin & Lu, 2020;Poppi et al, 2018;Salze et al, 2019) and shrimp species (Shiau & Chou, 1994;Yue et al, 2013). Our previous study showed that taurine supplement enhanced the growth performance after fishmeal replacement by more than 50% of soya bean concentrate in the diet of white shrimp (To & Liou, 2021). Moreover, Kim et al (2008) indicated that taurine supplements could improve lipid utilization of juvenile Japanese flounder.…”
