Foundation and perspectives of the use of plant extracts as performance enhancers in broilers

Abstract: Feed is responsible for about 70% of broilers production costs, leading to an increasing number of studies on alternative dietary products that benefit bird performance and lower production costs. Since the 1950s, antimicrobial additives are the most frequently used performance enhancers in animal production and their positive results are observed even in high-challenge conditions. Since the 1990s, due to the ban of the use of some antibiotics as growth promoters and the growing trend of the public to consume … Show more

“…Normally, the benefits induced by plant extracts to poultry were due to the antimicrobial activity, antioxidant activity, effects on digestibility or performance enhancers (Rizzo et al., ). In this study, the beneficial effects induced by PE supplementation is likely attributed to the antioxidant compounds such as gemin D, pedunculagin, tellimagrandin I, tellimagrandin II, pentagalloyl glucose and oenothein B (Chen, Wang, et al., ) and other relevant phenolic compounds in Eucalyptus leaves extracts.…”

“…Nowadays, supplementation of natural antioxidants to diet was a popular practice to reduce the oxidative stress in the poultry industry, which could improve poultry heath condition (Sahin et al., ; Starčević et al., ). On the other hand, the addition of medicinal plants to poultry diets is a growing trend to improve the quality of livestock products such as table egg ever since the ban of some antibiotics as growth promoters in 1990s (Rizzo, Menten, Racanicci, & Santarosa, ; Coorey, Novinda, Williams, & Jayasena, ; Goldberg et al., ).…”

“…Dietary antioxidant supplements from plant sources can enhance the quality of meat by minimizing oxidative stress on lipids and protein molecules and enhancing the activities of glutathione peroxidase, catalase, and superoxide dismutase, ultimately improving the amino acid and fatty acid profile of meat (Upton et al, 2009). Due to their potential health benefits, consumers are willing to buy meat from broilers fed botanical extracts (Rizzo et al, 2008). After reviewing the potentials of natural extracts, this study aimed at evaluating the effects of the dietary inclusion of botanical extracts on the amino acid and fatty acid profiles of broiler meat.…”

“…The antioxidant activity of plant extracts is mainly related to the presence of phenolic compounds. Moreover, compounds such as flavonoids and terpenoids also present antioxidant activity (Rizzo et al, 2008). In addition, antioxidative effects in probiotic strains such as S. cerevisiae have been reported by Zhang et al (2005).…”
