“…In birds, Se is indispensable for the synthesis of selenocysteine, i.e. an amino acid being a constituent of selenoproteins involved in metabolic processes, like glutathione peroxidase (GSH-Px), thioredoxin reductase, and iodothyronine deiodinase 22 . Dietary components used in broiler feeding, including mainly cereals, can be deficient in Se mainly due to its shortages in the soil.…”

Selenium is an essential element that is important for many metabolic processes. Feed components used in chicken nutrition, especially cereals, may be deficient in selenium, hence selenium supplementation is necessary. Taking into account the progress in breeding, and thus the higher demand of birds for this element, it seems obvious to investigate an increased selenium dose in the diet of chickens. The aim of the study was to evaluate the effect of feed enriched with different forms of selenium at an increased dose of 0.5 mg/kg feed on the profile and metabolism of fatty acids in the breast muscle and liver of chickens. The study was conducted on 300 Ross 308 chickens reared for 42 days under standard conditions. The control group received feed supplemented with sodium selenite at a dose of 0.3 mg/kg feed. The research groups received different forms of selenium (sodium selenate, selenised yeast, nano-selenium) at an increased dose of 0.5 mg/kg feed. The study showed that the administration of different forms of selenium in the feed affected its concentration in the breast muscle and liver (p ≤ 0.01). Nano-selenium was found to have a high bioavailability, but also a lower risk of toxicity compared to other forms of selenium. Using different forms of selenium (p ≤ 0.01) at a dose of 0.5 mg/kg feed can significantly modify the fatty acid profile, lipid and enzymatic indices of fatty acid metabolism in breast muscle and liver.

The objective of this experiment was to assess the effects of dietary sodium selenite and selenium (Se) yeast levels on growth performance, meat quality and muscle anti-oxidative capacity of broilers. A total of 360 1-day-old Cobb broilers were randomly assigned to 5 dietary treatments for 6 weeks. Diets (corn-soybean meal based diets) were supplemented with 0 mg/kg, 0.3 mg/kg and 0.6 mg/kg sodium selenium, and 0.3 mg/kg and 0.6 mg/kg selenium yeast, respectively. The results showed that Feed/Gain was significantly decreased with the increase of Se supplemental level during day 1-21 (P < 0.05), and body weight gain and Feed/Gain of broilers were improved with the increase of Se supplemental level by day 22 to 42 (P < 0.05). The dietary Se levels significantly affected the a*, cohesion, adhesion, chewing and recovery values of meat as well (P < 0.05). Se supplementation in diets also increased DPPH, hydroxyl radical scavenging and SOD, but significantly decreased TBARS and POV values compared to control (P < 0.05). The biological utilization rates of organic Se against inorganic Se were 116.0%, 123.1%, 109.7%, 109.8%, and 135.2%, respectively. The present results supported that organic Se was more bio-available and more effective in terms of growth performance, meat quality, muscle antioxidant and organ deposition efficiency compared to inorganic selenium. Therefore, the addition of 0.6 mg/kg selenium yeast (SY) during broiler breeding was the most effective.

“…A sufficient supply of Se in broiler feed can improve the antioxidant capacity, ensure the integrity and functioning of the cell membrane, alleviate lipid peroxidation of unsaturated fatty acids, and slow myoglobin oxidation in muscles, all of which improve the color of chicken meat and prolong its shelf life (1,5). Moreover, Se deficiency leads to white muscle disease, with muscle that appears pale and fluffy and with an exudate (6,7). China is one of the regions with the greatest Se deficiency in the world, the Se-deficient regions account for 72% of the country's area (8).…”

This study aimed to investigate the effects of the combination of selenium and Bacillus subtilis (Se-BS) on the quality and flavor of meat and slaughter performance of broilers. A total of 240 one-day-old Arbor Acres broilers were randomly allotted to four treatments of a basal diet supplemented with no selenium (control), sodium selenite (SS), BS, or Se-BS and raised for 42 days. Compared with the control group, Se-BS significantly increased the carcass weight, the half-eviscerated weight, the completely eviscerated weight, the carcass rate, and redness in broiler muscles; improved the antioxidant state by increasing glutathione peroxidase (GPx) and glutathione S-transferase activities, the total antioxidant capacity, and GPx-1 and thioredoxin reductase 1 messenger RNA (mRNA) levels; promoted biological activity by increasing the contents of glutamate, phenylalanine, lysine, and tyrosine; and increased Se and five types of nitrogenous volatile substances in muscles. On the other hand, Se-BS treatment decreased the shear force, drip loss, and the malondialdehyde, glutathione, and lead contents in muscles. Se-BS exerted a better effect on slaughter performance, the physicochemical quality of meat, the redox status, the amino acid contents, the trace element contents, and volatile substances compared with SS and BS. In conclusion, Se-BS had a positive effect on the quality and flavor of meat and slaughter performance of broilers, suggesting that Se-BS may be a beneficial feed additive.
