Effect of a non-hormonal feed additive, Cholymbi on growth, body composition and digestive enzyme activity of common carp, Cyprinus carpio.

Effects of different levels of Quillaja Saponin supplementation on growth and feed performance, digestive enzymes activity, nonspecific immunity and culture water quality of common carp (Cyprinus carpio) in Biofloc system

 This study aimed to evaluate the effects of different levels of dietary Quillaja saponin on the growth performence, digestive enzymes, water quality, and immune response of common carp in biofloc system. The fish (8.06 ± 0.59 g) were fed diets containing 0 (BC), 15 (BS1), 30 (BS2), and 60 (BS3) mg/kg saponin powder for 60 days. The growth performance and protease were significantly higher in t...

Evaluation of growth performance, digestive enzyme activity, immune and antioxidant parameters of Common carp (Cyprinus carpio L.) juveniles reared in aquaponic system

Aquaponic is considered a sustainable semi-closed system for food production that combines aquaculture and hydroponics. The aims of this study were to evaluate the influence of aquaponic on the growth and feed performance, digestive enzyme activity and blood parameters of Common carp juveniles for 60 days. This experiment consisted of three groups (three replications per group) which included; ...

Effect of different levels of dietary magnesium nanoparticles on growth, digestive enzymes activity and immune factors of common carp (Cyprinus carpio) under glyphosate exposure

The aim of this study was to evaluate the effects of different doses of magnesium-oxide nanoparticles (nano-Mg) on the growth performance, digestive enzyme activities, and some innate immune parameters in common carp fingerling (Cyprinus carpio). Nano-Mg was added to the experimental basal diets at the rates of 0 (control), 25, 50 and 100 mg/kg. Four groups of fish with an average weight of 12....

Effects of Zingiber officinale powder on growth parameters, survival rate and biochemical composition of body in juvenile common carp (Cyprinus carpio)

This study was conducted with different levels (0, 0.25, 0.5,1,2 g) of Zingiber officinale powder per 100 g of common carp commercial diet. Feed was offered for 8 weeks by the post pelleting liquid spraying method. Results showed that there were significant differences in all growth parameters and body composition except in survival rate, Gain Weight Percent (GW%) ,SGR and NFE between treatment...
