“…Hemolymph is an indicator of shrimp performance, health status, and rearing conditions, and is closely related to the innate immune system (Li et al 2008a;Chen et al 2015;Qiu et al 2016). In crustaceans, THC and PO system play important roles in the immune system, especially in shrimp (Sritunyalucksana and Söderhäll 2000;Li et al 2008a;Wanlem et al 2011).…”

This study examined the effects of dietary melamine (MEL) and cyanuric acid (CYA) singly and in combination on growth, nutrient utilization, immunological responses, oxidative stress, and histological changes in Pacific white shrimp. Seven experimental isonitrogenous (35%) and isolipidic (8%) diets were formulated, namely diet 1 (a control diet without MEL and CYA); diets 2-5 (with MEL and CYA at 2.5 ? 2.5, 5 ? 5, 7.5 ? 7.5 and 10 ? 10 g kg -1 diet); diet 6 (with only MEL at 10 g kg -1 diet) and diet 7 (with CYA alone at 10 g kg -1 diet). The shrimp with initial body weight 2.37 ± 0.02 g were fed with these diets for 10 weeks. The results indicate that all the diets with MEL and CYA singly or in combination had adverse effects on growth and nutrient utilization relative to the control diet (p \ 0.05). Total protease and trypsin activities were significantly lowered by all diets containing MEL (p \ 0.05). Haemolymph parameters, including total hemocyte count, phenoloxidase (PO) activity, respiratory burst, and lysozyme activity, were significantly decreased (p \ 0.05) in shrimp receiving MEL alone (10 g kg -1 diet) and at high combination dosages (10 ? 10 g kg -1 diet). Moreover, MEL and CYA induced oxidative stress, damaged hepatopancreas, decreased antioxidant responses, increased lipid peroxidation, and caused abnormality of hepatocytes.

“…The high dose of mycotoxins exposure may induce acute intoxication and increase the mortality of shrimp, and cause an economic loss to farmers only (Zimba, Camus, Allen, & Burkholder, ). However, the low doses of mycotoxins exposure also cause damage to tissues (Qiu et al, ), and may result in a lower food quality and nutritional value, and may be rejected by consumer. The quality of such contaminated aquatic products would further decline even in refrigerated storage (Srinivasan, Xiong, & Blanchard, ).…”

Mycotoxins widely contaminated the feed ingredients of shrimp, threatening the aquatic products, but their adverse effects on quality is less known. In this study, the adverse effects of T‐2 toxin (T‐2), aflatoxin B (AFB1), deoxynivalenol (DON), and ochratoxin (OTA) on the quality of Litopenaeus vannamei were investigated and compared. The results demonstrated that these four mycotoxins led the worse shrimp muscle color and tender texture, induced lipid peroxidation and pH change. Furthermore, four mycotoxins increased the K‐value and total volatile basic nitrogen (TVB‐N) to decrease the freshness. The median effective doses of T‐2, DON, AFB1, and OTA on TVB‐N of shrimp muscle were 4.86, 1.51, 0.26, and 0.20 mg/kg·bw, respectively. This study could provide useful information about the impacts and limited exposure dose of mycotoxins for quality preservation of shrimp. Practical applications The shrimp quality is easy to deteriorate as it is most likely to be exposed to mycotoxins because of intensive farming practices using grain‐based feeds, which were widely contaminated by mycotoxins. This study may provide a limited exposure dose of four prevailing mycotoxins aflatoxin B, deoxynivalenol, ochratoxin, and T‐2 for preserving the minimal quality of shrimp, and also provide useful information for predicting the quality of shrimp from those highly mycotoxins‐contaminated areas.

“…Measurement of biochemical factors such as phosphorous and albumin has previously reported as indicators of nutritional and metabolic status (Khajepour & Hosseini, ; Qiu et al, ). Urea, uric acid and creatinine are helpful to control culture conditions (Cheng, Lee, Shieh, & Chen, ; Lee & Chen, ), and alkaline phosphatase is a symbol enzyme of lysomase that contributes to the innate immune system (Qiu et al, ; Zhao et al, ). Determination of immunological parameter such as total hemocyte count (THC) reflects healthy aquatic animals (Sepici‐Dinçel et al, ).…”

Evaluation of some haemolymph biochemical properties and F‐cell prevalence in hepatopancreas of white leg shrimp (Litopenaeus vanammei) after fed diets containing apple cider vinegar and propionic acid

et al. 2019

View full text Add to dashboard Cite

The present study aimed to evaluate the effect of dietary ACV (apple cider vinegar) and PA (propionic acid) supplementation on some biochemical properties of haemolymph and fibrillar cell (F‐cell) number in the hepatopancreas of shrimp. Five different diets supplemented with 0%, 1%, 2%, 4% ACV and 0.5% PA diets were fed to Litopenaeus vanammei. Some biochemical parameters of haemolymph (cortisol, alkaline phosphatase, albumin, urea, uric acid, creatinine, phosphorus, total hemocyte count) and prevalence of F‐cell in hepatopancreas were examined after 60 days feeding trial. The albumin concentration and total hemocyte count in 2% and 4% ACV and PA groups were significantly higher than those of other groups (p < .05). Moreover, the highest phosphorus concentration was detected in shrimp fed 4% ACV and PA experimental diets (p < .05). No significant differences in haemolymph cortisol, urea, uric acid, creatinine, alkaline phosphatase and tubule area were observed among the experimental groups (p > .05). 2% ACV group showed more F‐cell number in hepatopancreas than other groups while the reduction in F‐cell number was observed in the PA group. Based on these observations, the tested ACV and PA diets remarkably exhibited positive impacts on nutritional value and they may be a potential for adding to shrimp diet.
