“…Around 3% of its main form, selenoproteins, is involved in the synthesis of Se-dependent glutathione peroxidase (GSH-Px), which scavenges free radicals such as reactive oxygen species (ROS) [30,[33][34][35]. Selenocystines represent a main component of the thyroxin system, which also comprises nicotinamide adenine dinucleotide phosphate [36]. All the components of this system facilitate the reduction in protein disulfides in ribonucleotide reductase, thioredoxin peroxidase, and protein disulfide-isomerase, which work harmoniously to regulate DNA synthesis and repair, antioxidant production, and proper functioning of the endoplasmic reticulum [36].…”

“…It also triggers thyroid dysfunction by inhibiting the conversion of thyroidal thyroxine to triiodothyronine [48,49]. This is because Se is a key structural component in selenocysteine, which exists in the active sites of enzymes involved in the thyroxin system such as iodothyronine deiodinases and thioredoxin reductases [36]. It also heightens the vulnerability to infections by promoting the evolution of pathogenic viral species [34,38], which frequently induce oxidative stress in order to direct physiological processes of host cells toward viral replication [50].…”

Effects of Selenium Supplementation on Rumen Microbiota, Rumen Fermentation, and Apparent Nutrient Digestibility of Ruminant Animals: A Review

Enzymes excreted by rumen microbiome facilitate the conversion of ingested plant materials into major nutrients (e.g., volatile fatty acids (VFA) and microbial proteins) required for animal growth. Diet, animal age, and health affect the structure of the rumen microbial community. Pathogenic organisms in the rumen negatively affect fermentation processes in favor of energy loss and animal deprivation of nutrients in ingested feed. Drawing from the ban on antibiotic use during the last decade, the livestock industry has been focused on increasing rumen microbial nutrient supply to ruminants through the use of natural supplements that are capable of promoting the activity of beneficial rumen microflora. Selenium (Se) is a trace mineral commonly used as a supplement to regulate animal metabolism. However, a clear understanding of its effects on rumen microbial composition and rumen fermentation is not available. This review summarized the available literature for the effects of Se on specific rumen microorganisms along with consequences for rumen fermentation and digestibility. Some positive effects on total VFA, the molar proportion of propionate, acetate to propionate ratio, ruminal NH3-N, pH, enzymatic activity, ruminal microbiome composition, and digestibility were recorded. Because Se nanoparticles (SeNPs) were more effective than other forms of Se, more studies are needed to compare the effectiveness of synthetic SeNPs and lactic acid bacteria enriched with sodium selenite as a biological source of SeNPs and probiotics. Future studies also need to evaluate the effect of dietary Se on methane emissions.

“…Selenium (Se) is an important trace element that acts as an antioxidant [ 8 , 9 ] and a cofactor for metalloenzymes [ 5 ]. Se deficiency is usually associated with several abnormalities, including placenta retention, impaired fertility, neonatal weakness, and abortion [ 10 ]. Acting as an enzymatic and protein cofactor, copper (Cu) plays important roles in the immune system [ 11 ].…”

Investigation of some trace elements and hematological and biochemical parameters in the blood of emaciated Omani goats

et al. 2021

Background and Aim: The analysis of hematological and biochemical parameters is widely used in assessing animal health status. Limited information is available on trace element levels and their association with hematological and biochemical parameters in Omani goats suffering from emaciation. Therefore, the current study aimed to determine the levels of some trace elements in emaciated Omani goats and their relationship with hematological and biochemical parameters. Materials and Methods: Goats suffering from emaciation and muscular dystrophy (n=18) were compared with healthy goats (n=12). Venous blood samples for the hematological, biochemical, and trace element analysis were collected from the jugular vein. Results: Emaciated goats showed significantly lower white blood cell, lymphocyte, and red blood cell counts than the healthy goats. In contrast, the percentages of monocytes and eosinophils were higher in emaciated goats than in healthy ones. In addition, emaciated goats showed higher levels of biochemical parameters alkaline phosphatase, alanine aminotransferase, gamma-glutamyl transferase, aspartate aminotransferase, creatine kinase, and total bilirubin but lower levels of albumin than the healthy goats. The results of trace element analysis revealed lower concentrations of zinc, iron, and selenium in serum from emaciated goats than in serum from healthy goats. Conclusion: This study identified significant differences in the serum levels of some trace elements and hematological and biochemical parameters between healthy and emaciated Omani goats. The identified differences represent valuable diagnostic biomarkers for the evaluation of the health status of Omani goats.

“…b Mineral premix was obtained the Earth Animal Nutrition and Health Products Co., Ltd.(Chongqing, China), and contained the following minerals per kilogram feed: 1,300 mg of Cu, 1,000 mg of Fe, 1,575 mg of Zn, and 595 mg of Mn.Se levels of 5-8 mg/kg DM in ruminants(12). Therefore, the goats were raised for 74 d, which included a preparation period of 14 d and a formal experimental period of 60 d. Eighteen Qianbei-pockmarked wether goats (a Guizhou native goat breed) were assigned to three groups (six duplicates per group) by body weight (BW, 25.75 ± 1.75 kg; mean ± standard deviation) according to a completely randomized design: (1) basal diet (CON); (2) CON with 2.4 mg/kg SY (LS); and (3) CON with 4.8 mg/kg SY (HS).…”

The objective of this study was to observe the effects of selenium-yeast (SY) on growth performance, muscle antioxidant activity, meat quality, fatty acid and amino acid profiles in growing goats. A total of 18 Qianbei-pockmarked goats were assigned to three groups (six duplicates per group) by body weight (25.75 ± 1.75 kg; mean ± standard deviation) according to a completely randomized design: (1) basal diet (CON); (2) CON with 2.4 mg/kg SY (LS); and (3) CON with 4.8 mg/kg SY (HS). The results indicated that goats receiving SY did not show any differences (P > 0.05) in terms of dry matter intake, growth performance, or muscle chemical composition. In addition, dietary treatment did not affect (P > 0.05) the pH values (pH45min and pH24h), percentage of water loss, drip loss, or cooking loss. The HS group showed a significant increase (P < 0.05) in the dressing percentage, eye muscle area and meat color, as well as muscle total antioxidant capacity, glutathione peroxidase and 2,2-diphenyl-1-picrylhydrazyl scavenging activity levels, whereas it showed a significant drop (P < 0.05) in shear force and muscle malondialdehyde levels relative to the control. Feeding 4.8 mg/kg SY led to a significant (P < 0.05) decrease in the levels of C8:0, C14:0, C15:0, C16:0, C17:0, C18:0, C20:0 and total saturated fatty acids, whereas it led to a significant (P < 0.05) increase in C15:1 in comparison with that of the control group. Goats receiving 2.4 mg/kg SY had significantly (P < 0.05) increased C16:1, C17:1, C18:1n7, C18:2n6, C18:3n3, C20:4n6, C22:1n9, and PUFA relative to the control group. Compared with the control group, the treatment groups had higher (P < 0.05) levels of C18:1n9, C22:4, and monounsaturated fatty acids. The inclusion of 2.4 mg/kg SY induced significant (P < 0.05) increases in 4-aminobutyric acid, glutamic acid and umami amino acid concentrations compared to the control. In addition, the feeding of 4.8 mg/kg SY had significantly higher (P < 0.05) muscle serine, valine, isoleucine, leucine, ornithine hydrochloride, methionine, and tyrosine levels than the control group. Collectively, Se supplementation in the diet did not affect growth performance, muscle chemical composition, whereas it could improve meat quality, muscle antioxidant activity, fatty acid and amino acid profiles in Qianbei-pockmarked goats. This showed that the optimal accession SY level was 4.8 mg/kg under the experimental conditions of this study.
