“…Livestock may access dietary antioxidants from the origin of flora (forages, crops, and grains) since several plant products are rich in delivering exogenous or endogenous antioxidants generated from macro-micro-nutrients or phytochemicals. Therefore, the provision of antioxidants, as diets or supplements for farm animals, can be a valuable practice to maintain animal health and optimize flock or herd productivity [ 150 , 151 ].…”

“…In the last two decades, there has been a growing interest in feeding animals with diets rich in antioxidant compounds to achieve potential health benefits to both animal and those who consume animal products [ 151 ]. The inclusion of by-products containing antioxidants and other bioactive compounds from agricultural industries in the diets of farm animals has been on the rise because: (1) they contain valuable nutrients as vitamins, minerals, and essential fatty acids, which can enhance animal performance and product quality; (2) they are available for use as animal feeds at lower prices compared to traditionally used cereal grains or protein meals; (3) availability of improved technologies for processing and preservation of animal feeds with by-products to eliminate microbial growth related health issues in animals; and (4) protection of the ecosystem when these residues are discarded in terrestrial and aquatic ecosystems, potentially causing environmental problems and economical losses.…”

The biological effects of oxidative stress and associated free radicals on farm animal performance, productivity, and product quality may be managed via dietary interventions—specifically, the provision of feeds, supplements, and forages rich in antioxidants. To optimize this approach, it is important first to understand the development of free radicals and their contributions to oxidative stress in tissue systems of farm animals or the human body. The interactions between prooxidants and antioxidants will impact redox homeostasis and, therefore, the well-being of farm animals. The impact of free radical formation on the oxidation of lipids, proteins, DNA, and biologically important macromolecules will likewise impact animal performance, meat and milk quality, nutritional value, and longevity. Dietary antioxidants, endogenous antioxidants, and metal-binding proteins contribute to the ‘antioxidant defenses’ that control free radical formation within the biological systems. Different bioactive compounds of varying antioxidant potential and bio-accessibility may be sourced from tailored feeding systems. Informed and successful provision of dietary antioxidants can help alleviate oxidative stress. However, knowledge pertaining to farm animals, their unique biological systems, and the applications of novel feeds, specialized forages, bioactive compounds, etc., must be established. This review summarized current research to direct future studies towards more effective controls for free radical formation/oxidative stress in farm animals so that productivity and quality of meat and milk can be optimized.

“…These include KCl, KH 2 PO 4 , NaHCO 3 , NaCl, MgCl 2 , (NH 4 ) 2 CO 3 , NaOH, HCl, and CaCl 2 , 2,2-Diphenyl-1-pricrylhydrazyl (DPPH), Folin-Ciocalteu reagent, 2,4,6-tripytidyl-s-triazine (TPTZ), gallic acid, sodium carbonate, ascorbic acid, sodium acetate, and ferric chloride. The antioxidant potential of digestive fractions was determined by high throughput 96-well plate methods [9,25]. The supernatants were collected at every digestive stage after centrifugation at 10,000× g for 20 min.…”

Chicory and lucerne possess high feed value for poultry being good sources of protein and fiber. In addition, they are rich in polyphenols that help the body build an integrated antioxidant system to prevent damage from free radicals and positively modulate microbial populations in the gastrointestinal tract. These health-promoting effects of polyphenols depend on their bioaccessibility and absorption in the animal body. The present paper aimed to study the bioaccessibility of polyphenols from chicory and lucerne after subjecting the samples to gastric and intestinal phases of digestion in an in vitro model of chicken gut and assessment of their feed value by measuring the presence of fermentable substrates (in terms of gas production), SCFAs produced and their effects on gut microbiota population during in vitro cecal fermentation. Results revealed that the bioaccessibility of polyphenols varied with different polyphenol compounds. The highest bioaccessibility was recorded for p-hydroxybenzoic acid (90.8%) from chicory following the intestinal phase of digestion. The lowest bioaccessibility was observed for quercetin-3-rhamnoside (12.6%) from chicory after the gastric phase of digestion. From lucerne, the highest bioaccessibility was recorded for kaempferol-3-glucoside (77.5%) after the intestinal phase of digestion. Total gas production was higher for lucerne (39.9 mL/g) than chicory (28.1 mL/g). Similarly, total SCFAs production was higher after 24 h of cecal fermentation with lucerne (42.2 mmol L−1) as compared to chicory (38.1 mmol L−1). Results also revealed that the relative abundance of Clostridium was reduced with chicory (0.225%) and lucerne (0.176%) as compared to the control (0.550%) after 24 h of cecal fermentation. The relative abundance of Streptococcus was reduced by lucerne (4.845%) but was increased with chicory (17.267%) as compared to the control (5.204%) after 24 h of fermentation. These findings indicated that chicory and lucerne differentially affected the microbial populations during in vitro cecal fermentation.

“…They offer various health benefits including antioxidant, anti-inflammatory, anti-obesity, and antihyperglycemic effects. [34][35][36] Epidemiological studies have shown that dietary polyphenols are associated with a lower T2DM risk. In vitro and in vivo data have shown that polyphenols improve glucose homeostasis via multiple mechanisms.…”
