“…Serum levels of ROS, one of the most harmful free radicals to the body, were significantly lower on day 21 in calves receiving microalgae, suggesting a lower production or better ability to eliminate this free radical, as observed by Sharma et al (2019) in fish supplemented with the Ascochloris spp.…”

This study evaluated the effect of different amounts of marine microalgae (Schizochytrium limacinum) via milk on performance, serum constituents and antioxidant indicators of dairy calves. Twenty-four Holstein calves were distributed to one of four treatments (six replicates) according to a completely randomized design: a control treatment (without microalgae), or microalgae supplementation at 6, 12 and 18 grams of microalgae per day supplied via milk. Two blood samples were taken, at 21 and 42 days of the experiment, to measure activities of antioxidant enzymes: glutathione S-transferase (GST), catalase (CAT), superoxide dismutase (SOD) as well as levels of reactive oxygen species (ROS). The supplementation of increased amount of microalgae did not influence dry matter intake (DMI) and performance (P>0.05). At the 21 days of life, there was a linear increase in serum protein (P = 0.03), globulin (P = 0.006) and in SOD activity (P = 0.05). Linear reduction in ROS (P = 0.001) and a quadratic effect for heavy immunoglobulin G (IgG) (P = 0.02) were observed as the microalgae amounts increased. Close to weaning, at 42 days, serum globulin (P = 0.003), GST (P = 0.002) and SOD (P = 0.02) linearly increased with the inclusion of microalgae. Conversely, enzymatic activity of CAT showed a quadratic effect (P = 0.05). Supplementation of microalgae via milk did not influence intake and performance dairy calves. However, the use of microalgae as a feed additive to dairy calves at amount of 6 g/d is recommended due to its stimulation of antioxidant enzymes and reduction on serum levels of free radicals.

“…Catalase can catalyze the decomposition of H 2 O 2 into water and molecular oxygen (O 2 ; Sharma et al 2019), thereby removing excess H 2 O 2 from the body and protecting cells from H 2 O 2 damage. Compared with the control group, after 3 d of exposure (Figure 2C), CAT activities significantly increased by 20.1% in the low S ‐(−)‐dufulin treatment group.…”

Dufulin is a new type of chiral antiplant virus agent independently developed in China. The present study was conducted to determine the effects of different concentrations of rac-dufulin and dufulin enantiomers (1, 5, and 10 mg/L) on oxidative stress in Tubifex after exposure for 3, 7, and 14 d. Results showed that rac-dufulin and individual enantiomers had no significant effects on total protein content and glutathione reductase activities. Increased superoxide dismutase demonstrated the generation of superoxide anion radical. The increase in glutathione S-transferase may be due to detoxification mechanisms. The different changes in catalase activities could be due to oxidative stress. The increase in malondialdehyde may be due to the accumulation and toxicity of contaminations. The degradation behavior of dufulin enantiomers was studied through spiked-water and spiked-soil tests. The degradation rate of S-(+)-dufulin was faster than that of R-(−)-dufulin. The present study demonstrated the occurrence of enantioselectivity in the degradation and oxidative stress of dufulin to Tubifex. In spiked soil, the concentrations of dufulin enantiomers in underlying soil were significantly higher than those in overlying water; but after 5 d of degradation, the bioturbation of Tubifex could facilitate part of dufulin diffusing from the underlying soil into the overlying water and altered the partitioning of dufulin. The present study provided a basis for conducting environmental safety risk assessments and rationally using dufulin as a chiral pesticide.

“…in diets for the same species [73] even at lower levels (2.5%). In addition, high values of CAT associated with the inclusion of seaweeds in diets have been described in a number of studies [67,74,75]. Again, the observed reduction in the activity of CAT in fish initially fed on any of the diets, including rancid oil (UO, CO), that after receiving the feed with U. ohnoi during the recovery period suggests the onset of a metabolic response oriented to reduce the amount of oxidation products.…”

This study evaluated the use of Ulva ohnoi as an ingredient in feeds for aquaculture in three different experiments. Experiment 1 was oriented to confirm the negative effect of U. ohnoi on fish digestion. Experiment 2 assessed the effect on growth, feed efficiency, and immune status of juvenile sea bass (Dicentrarchus labrax) fed on diets including U. ohnoi, previously treated or not with carbohydrases used to partially hydrolyze indigestible polysaccharides. Experiment 3 was aimed to evaluate the potential protective effect of U. ohnoi on the oxidative status of sea bream (Sparus aurata) challenged by the consumption of a feed formulated with the oil fraction completely oxidized. Results show a negligible effect of U. ohnoi meal on protein digestion when included in feeds at levels of 10% or less. Moreover, results of growth and feed use evidenced the possibility of using up to 5% inclusion of algal meal in feeds without adverse effects on the zootechnical parameters, while the enzyme pretreatment was ineffective to improve its nutritional use. Finally, the inclusion of U. onhoi in feeds determined both an immunostimulatory effect, evidenced by an increase in skin mucus lysozyme in the two mentioned fish species, and a positive influence on the oxidative metabolism of seabream when fed on a diet including rancid oil.
