“…Similar with our results, increasing dietary Se levels increased the TAC content of laying hen [46]. Selenium is an indispensable part of glutathione peroxidase enzyme and its combination with VE may protect the body against cellular lipid peroxidation [46,47].…”

The effect of dietary supplementation with VE and Se on the laying productive performance, immunity, and the quality parameters of fresh and stored eggs was assessed. For this study, five treatments, namely control (basal diet), control plus 30 mg of VE and 0.4 mg kg−1 sodium selenite (VE30SS), control plus 30 mg of VE and 0.4 mg kg−1 of Sel-Plex® (VE30SP), control plus 120 mg VE and 0.4 mg kg−1 Sodium selenite (VE120SS), and control plus 120 mg VE and 0.4 mg kg−1 Sel-Plex (VE120SP), were examined. There was no huge impact of VE and Se on feed consumption, FCR and egg yield rate. Quality parameters of fresh egg including egg surface area, eggshell thickness, yolk selenium concentration, albumen height, and Haugh unit were significantly increased following VE and Se supplementation (p < 0.05). For stored eggs, VE and Se significantly increased egg yolk color intensity (p < 0.05). Regardless of storage temperature, eggs from birds fed with VE and Se had less weight loss during 30 days of storage. Albumen height was significantly higher in VE and Se fed birds in eggs stored at 5 °C for 15 and 30 days. The combination of Sel-Plex with either levels of VE had significantly higher blood total antioxidant capacity. Dietary VE and Selenium, notably Sel-Plex, improved the antioxidant potential of blood and egg quality of laying quails.

“…Prakash et al (2007) state that EW has antioxidant potential and hepatoprotective properties. Also, Sun et al (2020) found that layer hens fed EW had increased protein, globulin, and albumin levels, but decreased triglycerides, cholesterol, and glucose suggesting that EW could be a potential dietary substitute for these birds.…”

The objective of this study was to evaluate the use of earthworm meal (EW) and vermi-humus (VH) in broiler diets. A total of 225 day-old male broilers were divided into 5 treatment groups with 3 repetitions of 3 birds each. The treatment groups were: T1control (no EW or VH; T2 À 1.0% EW and 0% VH; T3 À 1.0% EW and 1.0% VH; T4 À 1.0% EW and 1.5% VH; and T5: 1.0% EW and 2.0% VH. The birds received (EW) and (VH) for 14 d, and after this period, they received the common diet. The birds were reared for 42 d and, at 42 d, one representative broiler chicken per pen, close to the average body weight, was selected for blood sampling using a sterile needle and heparinised vacuum tube. Performance data, blood results, immunity, ileum morphology and microbiota, the relative weight of carcass components and gastrointestinal organs, malondialdehyde (MDA) content, and breast and thigh meat quality were evaluated. EW and VH had a positive effect on the immune response of broilers, as well as producing a reduction in the aerobic bacteria in the birds' intestines. HIGHLIGHTSProtein is a limiting factor for broiler performance, carcass yield, and meat quality; Poultry industry is searching for new protein sources which can be used on broiler diets; Insects meal are good protein sources in broiler nutrition and can be used on diets without compromising its performance.

“…In addition to naturally active products, some essential trace elements, such as Zn and Se, and vitamins perform similar biological functions in the body (e.g., anti-inflammatory and antiviral activities) through the NF-kB pathway. Se inhibits NF-kB pathway activation and reduces oxidative stress levels and promotes the expression of the antiinflammatory cytokine IL-2 (132)(133)(134). Vitamins C, D, and E all regulate NF-kB signaling and have biological activity (135)(136)(137).…”

Cadmium (Cd), a biologically non-essential heavy metal, is widespread in the environment, including the air, water, and soil, and is widely present in foods and quantum dot preparations. Cd enters the body primarily through inhalation and ingestion. Its biological half-life in humans is 10–35 years; therefore, Cd poses long-term health risks. While most studies on Cd toxicity have focused on organ and tissue damage, the immunotoxicity of Cd has drawn increasing attention recently. Cd accumulates in immune cells, modulates the function of the immune system, triggers immunological responses, and leads to diverse health problems. Cd acts as an immunotoxic agent by regulating the activity and apoptosis of immune cells, altering the secretion of immune cytokines, inducing reactive oxygen species (ROS) production and oxidative stress, changing the frequency of T lymphocyte subsets, and altering the production of selective antibodies in immune cells. This review summarizes the immunological toxicity of Cd, elucidates the mechanisms underlying Cd toxicity in terms of innate immunity and adaptive immunity, and discusses potential strategies to alleviate the adverse effects of Cd on the immune system.
