The effects of different levels of Chlorella microalgae on blood biochemical parameters and trace mineral concentrations of laying hens reared under heat stress condition

Abstract

This study was conducted to investigate the effect of different supplementation levels of Chlorella microalgae on serum metabolites and the plasma content of minerals in laying hens reared under heat stress condition (27.5-36.7 °C, variable). A total number of 378 (40 weeks of age, with mean body weight of 1390 ± 120 g) were randomly allocated to six treatments with seven replicates. The birds were randomly assigned to 6 treatments (C, T1, T2, T3, T4, and T5) with 7 replicate cages of 9 birds. C. microalgae at the rates of 100, 200, 300, 400, and 500 ppm with water were offered to groups T1, T2, T3, T4, and T5, respectively, while group C served as a control. At 71 days of trial, blood samples (14 samples per treatment) were taken for measuring serum metabolites and at 72 days for plasma mineral analysis. The results of this experiment showed that the supplementation of 200-500 ppm C. microalgae decreased the serum content of cholesterol, triglycerides, and LDL (P < 0.05) whereas HDL content increased (P < 0.05) in the hens supplemented with C. microalgae (300 or 400 and 500 ppm). C. microalgae at rates of 300-500 ppm caused a marked (P < 0.05) increase in the plasma content of manganese or iodine and selenium but other minerals were not statistically different among treatments. Overall, from the results of the present experiment, it can be concluded that supplementation of C. microalgae at high rates was beneficial on blood parameters of laying hens reared under heat stress.

Mitigation of endogenous oxidative stress and improving growth, haemato-biochemical parameters, and reproductive performance of Zaraibi goat bucks by dietary supplementation with Chlorella vulgaris or/and vitamin C

“…The current work declared that dietary supplementation of CV and/or VC exerted a significant could increase selenium levels in the blood, thus enhancing the antioxidant status (Moradi et al 2016). Vitamin C protective mechanisms may be through enhancing immune function via its role as an antioxidant that can easily donate electrons to free radicals and minimize the production of mutagenic metabolites because of its electrophilic nature, besides stimulating the production of interferon protein that protects cells from virus attack (Nitra and Silvia 2017).…”

Dietary supplementation with Chlorella vulgaris in broiler chickens submitted to heat-stress: effects on growth performance and meat quality

“…Moreover, the dietary supplementation with very low levels of C. vulgaris (0.2 g/kg) has been reported to improve growth performance in heat-stress broilers ( Ziar-Larimi et al, 2018 ). The supplementation in drinking water (300–500 mg/kg) with the same microalgae had beneficial impacts on serum contents of triglycerides, cholesterol, LDL, and HDL in laying hens exposed to chronic heat stress ( Moradi kor et al, 2016 ), which were ascribed to a radical scavenging and hypolipidemic action of the β-1, 3-glucan found in the cell wall of this microalgae and/or the presence of antioxidant substances.…”

Evaluation of the Role of Spirulina platensis and Chlorella vulgaris on Growth Performance, Meat Quality and Blood Parameters of Broiler Chickens

“…Moreover, total protein, globulin, and albumin did not significantly change from the control, but ALT, AST, and creatinine were significantly higher. Moradi Kor et al (2016) demonstrated that high of Chlorella microalgae had favorable effects on blood triglyceride, cholesterol, LDL, and HDL concentrations. This is consistent with previous findings by Canogullari Dogan et al, 2016 found that although not statistically, supplementing with Spirulina platensis also reduced the levels of plasma triglycerides between groups.…”
