“…These free radicals have strong toxicity and cause damage to biological macromolecules such as carbohydrates, proteins, lipids, and DNA, and finally leading to oxidative stress and the recession of physiological function, immunity, and production performance, thus causing diseases (Thannickal and Fanburg 2000 ; Gill and Tuteja 2020 ). In order to respond to the adverse effects of oxidative stress, the anti-oxidative defence system (AOS) release various enzymes such as CAT, GSH-Px, and SOD (Prokić et al 2018 ). Superoxide dismutase can convert superoxide anion radical (·O 2 − ) into hydrogen peroxide (H 2 O 2 ), subsequently, H 2 O 2 is broken into H 2 O by CAT or GSH-Px (Olsvik et al 2005 ).…”

This study investigated the effects of substitution of whole corn silage (WCS) with Broussonetia papyrifera silage (BPS) in different ratios on the serum indicators, hindgut fermentation parameters (pH, ammoniacal nitrogen, and volatile fatty acids), and fecal bacterial community of Holstein heifers. Sixteen heifers (8-month-old, 220 ± 30 kg) were randomly divided into four treatments according to different BPS substitution ratios of feed basis (0%, 25%, 50%, and 75%). The experiment consisted of a 7-day preliminary feeding period and a 30-day experimental period. On the last day of the trial, the blood samples were collected from caudal vein, and the feces samples were collected from rectum. With the increasing of BPS content, the concentration of malondialdehyde (MDA) and interleukin-1β (IL-1β) in serum decreased (P < 0.05), and the immunoglobulin A (IgA) and IL-4 content of serum increased (P < 0.05); and the hindgut pH value increased (P < 0.05). 16S rRNA sequencing found that the dominant phyla were Firmicutes, Bacteroidetes, and Verrucomicrobia; and the dominant genera were Ruminococcaceae_UCG-005, Ruminococcaceae_UCG-010, and Rikenellaceae_RC9_gut_group. Linear Discriminant Analysis Effect Size (LEfSe) analysis found 12 differential operational taxonomic units (OTUs) which have strong correlation with some serum and hindgut indicators, and have the potential to be used as biomarkers. Phylogenetic Investigation of Communities by Reconstruction of Unobserved States (PICRUSt) found that BPS have impacts on the pathways, such as carbohydrate transport and metabolism, and promotes amino acid transport and metabolism. To sum up, inclusion of BPS in heifer diets can affect serum anti-oxidant and immune indicators, fecal parameters, composition and function of fecal microorganisms in Holstein heifers.

“…Similar results were found on Nile tilapia, O. niloticus (Abdel‐Tawwab et al., 2014, 2015; Delaney & Klesius, 2004); channel catfish, I. punctatus (Thomas et al., 2007); and grass carp , Ctenopharyngodon idella (Gan et al., 2013) stressed by hypoxic condition. The rise in glucose concentrations was due to the mobilization of energy storage under fatigued conditions of low DO, as a source of fuel for anaerobic metabolism (Faggio et al., 2016; Prokic et al., 2018). On the same line, Mahfouz et al.…”

The present study investigated influence of Yucca schidigera extract (Ys E) on the growth performance, hepato‐renal function, antioxidative status and histopathological alterations in Nile tilapia (Oreochromis niloticus) exposed to hypoxia stress. 120 Nile tilapia fish (42.39 ± 1.25 g) were distributed into four equal groups, where group (a) kept as a control group, group (b) supplied with YsE (8 mg/L water every 2 days), group (c) exposed to hypoxia after 2 weeks from the start of the experiment and group (d) provided with YsE for 2 weeks and then exposed to hypoxia. The treatments were conducted for 30 days. The results showed that the level of DO was significantly decreased (2.2 ± 0.61) in groups of fish exposed to hypoxia when compared to other groups (p < 0.05). Notably, the pre‐supplementation with YsE to hypoxic stressed fish positively affected the WG, SGR, FCR and PER, relieved stress picture of leukogram, reduced the elevated hepatic marker enzymes: ALT, AST and LDH. Furthermore, hypoxic fish pre‐treated with YsE succeeded to decline the increased urea, glucose levels and the elevated serum amlyase and lipase enzyme activities. In addition to improving total proteins, albumin, total cholesterol, triglycerides, VLDL‐C and HDL‐C declined levels compared to hypoxic fish. Meanwhile hypoxia‐stressed fish exhibited significantly enhanced hepatic GPX, SOD and GSH and inhibited hepatic MDA content compared to fish supplied with YsE then exposed to hypoxia. Fish group pre‐supplemented with YsE then exposed to hypoxic stress condition was protected against the pathological changes of the liver, spleen, brain and gills tissues induced by hypoxic stress condition. These results suggest that YsE could exert a beneficial effect against hypoxia‐induced oxidative stress.

“…The toxic effect of metals appears to rely on generating reactive oxygen species (ROS) in the biological system. The toxic effect of heavy metals appears to be related to the production of ROS in biological systems, which affect various cellular processes, mostly the functioning of the membrane system (Cuypers, Vangronsveld, & Clijsters, ; Pinto et al, ; Prokic et al, ). The potential of ROS to damage tissues and cellular components is called oxidative stress, which occurs when the rate of ROS formation exceeds the rate of their decomposition by the antioxidant defense system.…”

Environmental health has always been threatened by the bioaccumulation of heavy metals in the terrestrial ecosystem, affecting its quality and safety. The aim of this review is to investigate the effects of heavy metal soil contamination, using the land snail Helix aspersa as a bioindicator. H. aspersa, a common species of land snail present in the area, has been used as a bioindicator of metal contamination and represents a promising ecological indicator. Various land snails species have become popular in microcosm studies because they accumulate high concentrations of certain trace metals. They express contamination as a whole through ingestion of polluted foods, such as live plants, microorganisms, soil, and water and also through cutaneous contact and from the polluted air they breathe. Land snails are considered appropriate sentinel species because trace metals tend to accumulate in their digestive gland to allow biomonitoring of metal pollution. Different experiments demonstrate that exposure in areas chronically polluted with metals, especially with lead, often causes changes in reproduction, with a variation in the mineral composition in the snail's eggs and also in its development, due to increased energy expenses associated with detoxification and the excretion process.
