Effect of bioherbal feed supplement (contains Foeniculum vulgare and Zingiber officinale powder) on function of liver and digestive enzymes and chemical parameters in Mugil cephalus

Abstract

Introduction: With the rapid expansion of the aquaculture industry, in order to meet the
protein needs of humans, stress and susceptibility of fish to disease in the intensive
system has increased. Therefore, the use of many dietary supplements such as feathers
probotics, safety stimulants, and plant products have been developed to combat the side
effects associated with growing conditions. This experiment was conducted to evaluate
the effect of bioherbal feed supplement on the liver (aspartat aminotransferase (ASP),
Alani aminotransferase (ALT) and alkanin phosphatase (ALP)) and digestive enzymes
(amylase, protease and lipase) and chemical parametese (glucose (GLU), cholesterol
(CHO), triglyceride (TRI), total protein (TP), albumin (ALB) and globulin (GLO) of
Mugil cephalus for 60 days.
Materials & Methods: The experiment was conducted in a completely randomized
design with 450 of grey mullet larvae (with average weight of 0.72±0.01g) in 5
treatments and 3 replicates (n=30 in each replicate) and included: control group without
using bioherbal, another groups (treatment 2, 3,4 and 5) the amounts of this herbal
supplement were 5,10,15 and 20 g/kg food.
Result: At the end of experiment , the results showed that the highest the activity of
protease (341±12.08U/mg protein), amylase (404.67±11.23 U/mg/protein) and lipase
(5.76±0.18 U/mg protein), the lowest ASP (92.66±13.05U/mL), ALT (15.33±1.15
U/mL) and ALP (66.33±2.51 U/mL) enzymes were observed in the diet containing 20 g
/kg bioherbal supplement in all of these parameters, treatment 5 (20 g/kg) (4) showed a
significant difference compared with control treatment (P<0.05). Also, the lowest serum
CHO (120.66± 3.78 mg/dL), GLU (80.33± 1.57 mg/dL) and TRI (120.06±9.01 mg/dL),
the highest GLO (1.52±0.15 g/dL) were recorded in treatment 4.
Conclusion: Finally, the present results suggest that diet containing 20 g/kg bioherbal
supplement (ginger and fennel powder) could improve digestion and liver function index
enzymes and biochemical parameters of Mugil cephalus larvae.
