“…Food crops that are commonly biofortified include cereals [29], leafy vegetables like spinach [30] and lettuce [31], and fruits like strawberry [24,32,33] and pomegranate [23]. Due to their lower toxicity, strong capacity to scavenge free radicals, higher bioavailability, and stimulation effect, Se-NPs have been recently used in the production of plants [23,24,[34][35][36], fish [37][38][39][40], livestock [41], and poultry [42][43][44][45][46][47][48].…”

Selenium and Nano-Selenium Biofortification for Human Health: Opportunities and Challenges

Selenium is an essential micronutrient required for the health of humans and lower plants, but its importance for higher plants is still being investigated. The biological functions of Se related to human health revolve around its presence in 25 known selenoproteins (e.g., selenocysteine or the 21st amino acid). Humans may receive their required Se through plant uptake of soil Se, foods enriched in Se, or Se dietary supplements. Selenium nanoparticles (Se-NPs) have been applied to biofortified foods and feeds. Due to low toxicity and high efficiency, Se-NPs are used in applications such as cancer therapy and nano-medicines. Selenium and nano-selenium may be able to support and enhance the productivity of cultivated plants and animals under stressful conditions because they are antimicrobial and anti-carcinogenic agents, with antioxidant capacity and immune-modulatory efficacy. Thus, nano-selenium could be inserted in the feeds of fish and livestock to improvise stress resilience and productivity. This review offers new insights in Se and Se-NPs biofortification for edible plants and farm animals under stressful environments. Further, extensive research on Se-NPs is required to identify possible adverse effects on humans and their cytotoxicity.

“…These Se forms showed high bioavailability and ability to improve meat quality and oxidative stability of broiler chickens, as well as production of Se-enriched meat [ 5 ]. According to Bakhshalinejad et al [ 6 ] supplementation of organic sources of Se (Se-yeast, selenomethionine, and nano-Se) resulted in a better meat quality compared with the inorganic source (sodium selenite) in broiler chickens. Moreover, dietary intake of 0.3 g/kg Se-yeast, Se-methionine, and nano-Se showed lower levels of shear force and cooking loss with high level of GSH-Px of breast muscles in local Chinese Subei chickens compared to the sodium selenite [ 7 ].…”

Selenium (Se) is able to transform from inorganic to organic forms via many bacterial species. This feature is being considered for delivering more bioavailable selenium compounds such as selenocysteine and selenomethionine for human and animal diet. This study investigated the effects of bacterial selenoprotein versus inorganic Se on the carcass characteristics, breast meat selenium content, antioxidant status, and meat quality of broiler chickens. One hundred and eighty chicks were randomly allotted to five treatments of a basal diet supplemented with no Se, sodium selenite, Enterobacter cloacae Selenium (ADS1-Se), Klebsiella pneumoniae-Selenium (ADS2-Se), and Stenotrophomonas maltophilia-Selenium (ADS18-Se). The results showed that bacterial selenoprotein has the ability to deposit more Se in the breast meat compared to sodium selenite. Both Se sources reduced breast meat drip loss, cooking loss, shear force, and 2-thiobarbituric acid reactive substances (TBARS) significantly. It also increased total antioxidant (TAC) and glutathione peroxidase (GSH-Px) in comparison with the negative control. The highest activity of (GSH-Px), catalase (CAT), and superoxide dismutase (SOD) was found in bacterial selenoprotein. In conclusion, bacterial selenoprotein is more efficient than sodium selenite in increasing the breast meat Se deposition and oxidative capacity of broiler chickens. Therefore, it can be effectively used to produce Se-rich meat as a functional food.

“…Furthermore, the carcass, which is used for determining the feed cost [18], is measured at the age of 42 days. Concerning the carcass yield, it was determined from the weight of the hot eviscerated carcass in relation to the individual body weight measured before slaughter [23]. The results found in chicks fed with two different feeds are recorded in Table 2.…”

In Morocco, the food waste fraction constitutes a large part of the total municipal solid waste generated. In order to promote this fraction as a feed source for poultry, a study was carried out to evaluate its digestive and metabolic effects, as well as its nutritional value on broilers. Indeed, comparative tests were carried out on two separate batches of small broilers fed, successively, with a commercial compound feed (CCF), and a feed prepared in the laboratory using kitchen waste as a substitute (LPF). The results obtained throughout the rearing period revealed the feasibility of the valorization of food waste as a substitute promoted in the poultry feed sector. In addition, the prefabricated feeds gave the same feed consumption index (1.03), compared to the commercial compound feed applied in the same rearing farm, while the weight gain index results were more advantageous for FPL. The study demonstrates the valorisation of feed waste as a new substitute for poultry feed.
