“…Moreover, the oxidative stress caused by intracellular reactive oxygen species (ROS) would also activate the corresponding antioxidant defense system, which is composed of enzyme components such as CAT, GR and GSH-Px and non-enzyme components such as T-SOD, GSH and T-AOC ( Landry et al, 2015 ). It was reported that feeding Lactobacillus plantarum -treated silage increased dairy goat’s serum antioxidase activity, such as T-AOC, SOD, GSH-Px and CAT ( Li et al, 2022 ). This was consistent with the results of serum, liver and spleen fed FPG in this study.…”

“…Cytokines are secreted by activated immune cells such as Th1 cells, which can interact with each other to form a signal network and play a role in regulating the host immune level ( Zeng et al, 2021 ). Previous studies have shown that probiotics might affect the secretion of immunoglobulin (IgA, IgM, and IgG) and cytokines (IL-2 and IL-4) by immune organs and cells, thus improving the immune function of the body ( Alizadeh et al, 2022 ; Li et al, 2022 ). This is consistent with the results (FPG) of this study.…”

IntroductionThis study was conducted to evaluate the effects of fermented feed of Pennisetum giganteum (P. giganteum) on growth performance, oxidative stress, immunity and gastrointestinal microflora of Boer goats under thermal stress.MethodsThe study was conducted during 45 days using twenty 2 months Boer goats. The goats were randomly allocated into two groups: NPG (n = 10; normal P. giganteum) and FPG (n = 10; fermented feed of P. giganteum), and the ratio of concentrates to roughage was 3:2. Both groups of animals were kept in sheds and exposed to summer thermal stress from 10:00 h to 18:00 h (temperature and humidity index, THI > 78). At the end of the study, the animals were slaughtered and assessed for various characteristics.ResultsThe findings from the study revealed that FPG-feeding significantly increased (p < 0.05) average daily gain (ADG, 48.18 g) and carcass weight (4.38 kg), while decreased (p < 0.01) average daily feed intake (ADFI, 0.74 kg/d; p < 0.01) and the feed:gain (F/G, 15.36) ratio. The CAT, GSH-Px activities and GSH in serum, liver and spleen, and the levels of IgA, IgG, IgM, IL-2, IL-4 and IL-1β in serum of FPG-fed goats were significantly higher (p < 0.05) than those of NPG-feeding goats. Further, we found that FPG feed is rich in nutrients with Lactobacillus (65.83%) and Weissella (17.80%). Results for gastrointestinal microbiota composition showed that FPG-feeding significantly enhanced the abundance of Lactobacillus and unidentified Clostridiales, and reduced Anaerovibrio and Methanobrevibacter. Meanwhile, Spearman’s correlation analysis showed that these microbiotas were closely related to the improvement of oxidative stress and immune indexes of goats.DiscussionThese results demonstrated that FPG-feeding not only reduces oxidative stress and improves ROS clearance to enhance antioxidant defense system, but also improves gastrointestinal microbiota to enhance immune function by overcoming the adverse effects of heat stress, and further improve growth performance of goats.

“…Moreover, Kang et al ( 2009 ) and Jin et al ( 2015 ) have reported improvement in the DM and neutral detergent fibre (NDF) digestibility of silages treated with feruloyl esterase‐producing Lactobacillus ( Lentilactobacillus ) buchneri in situ. Furthermore, animal trials have revealed that in addition to improving silage fermentation and digestion, feruloyl esterase‐producing bacteria enhanced the antioxidant and immune properties of animals (Li, Zhang, et al, 2022 ). Addah et al ( 2012 ) also demonstrated that inoculation of whole‐crop barley silage with a mixed culture of homolactic bacteria and feruloyl esterase‐producing Lactobacillus ( Lentilactobacillus ) buchneri at ensiling improved the efficiency of body weight (BW) gain in growing feedlot steers.…”

“…However, whether silage treated with such inoculants can improve the antioxidant status of ruminants and ruminant products remain unclear. At present, only one of our previous studies proved that the application of feruloyl esterase‐producing strain Lactobacillus ( Lactiplantibacillus ) plantarum A1 to silage could improve the antioxidant status of lactating dairy goats because of the free ferulic acid produced during ensiling (Li, Zhang, et al, 2022 ).…”

Lactic acid bacteria (LAB) play pivotal roles in the preservation and fermentation of forage crops in spontaneous or inoculated silages. Highlights of silage LAB over the past decades include the discovery of the roles of LAB in silage bacterial communities and metabolism and the exploration of functional properties. The present article reviews published literature on the effects of LAB on the succession, structure, and functions of silage microbial communities involved in fermentation. Furthermore, the utility of functional LAB in silage preparation including feruloyl esterase‐producing LAB, antimicrobial LAB, lactic acid bacteria with high antioxidant potential, pesticide‐degrading LAB, lactic acid bacteria producing 1,2‐propanediol, and low‐temperature‐tolerant LAB have been described. Compared with conventional LAB, functional LAB produce different effects; specifically, they positively affect animal performance, health, and product quality, among others. In addition, the metabolic profiles of ensiled forages show that plentiful probiotic metabolites with but not limited to antimicrobial, antioxidant, aromatic, and anti‐inflammatory properties are observed in silage. Collectively, the current knowledge on the roles of LAB in crop silage indicates there are great opportunities to develop silage not only as a fermented feed but also as a vehicle of delivery of probiotic substances for animal health and welfare in the future.

Hypertension, as a leading risk factor for cardiovascular diseases, is associated with oxidative stress and impairment of endogenous antioxidant mechanisms, but there is still a tremendous knowledge gap between hypertension treatment and nanomedicines. Herein, we report a specific nanozyme based on ultrathin two‐dimensional (2D) niobium carbide (Nb2C) MXene, termed Nb2C MXenzyme, to fight against hypertension by achieving highly efficient reactive oxygen species elimination and inflammatory factors inhibition. The biocompatible Nb2C MXenzyme displays multiple enzyme‐mimicking activities, involving superoxide dismutase, catalase, glutathione peroxidase, and peroxidase, inducing cytoprotective effects by resisting oxidative stress, thereby alleviating inflammatory response and reducing blood pressure, which is systematically demonstrated in a stress‐induced hypertension rat model. This strategy not only opens new opportunities for nanozymes to treat hypertension but also expands the potential biomedical applications of 2D MXene nanosystems.
