“…Studies reporting positive effects of dietary -tocopherol on lipid oxidation in n-3 PUFA enriched pork all compared against a basal diet containing 0-50 mg kg −1 dietary -tocopherol 8 -13 and no additional benefit of increasing dietary -tocopherol supplementation from 200 to 400 or 500 mg kg −1 was found. 8,10 In addition, Trefan et al 23 also reported a gradual decrease in TBARS in conventional pork as levels of dietary -tocopherol increased up to 100 mg kg −1 , with no further changes at higher levels of supplementation. Regretably, in the present study, the diet combining fish oil and a basal level of -tocopherol (Fish50), contained higher concentrations of -tocopherol than originally formulated.…”

“…In another study, Onibi et al used two levels of α-tocopherol acetate (200 mg/kg −1 and 500 mg/kg −1 ) and two basal diets in pigs for 35 days. The authors concluded that there was an increase in the muscle tocopherol levels depending on the diet fed [ 38 , 93 , 94 ].…”

The perceived level of risk associated with a food product can influence purchase and consumption decisions. Thus, current trends in food safety address an issue of general interest—the identification of healthy and economical alternatives to synthetic antioxidants that may have harmful effects on human health. Still, the processors’ target is to increase the shelf life of food products using preserving substances. Natural antioxidants can be extracted and used in the food industry from different plants, such as blueberry, broccoli, chokeberry, cinnamon, ginger, olives, oregano, etc. The identification of the main natural antioxidant types that have been used in the food industry is very important in order to provide a comprehensive analysis of the researched topic. In this regard, the aim of this paper was to illustrate the positive aspects of using natural antioxidants with preservative roles in meat products, while, at the same time, highlighting the potential risks induced by these compounds. All of those aspects are correlated with the impact of sensorial attributes and the improvement of the nutritional value of meat products.

“…In recent times there has been a paradigm shift by poultry producers in pursuit of improving chicken health. In order to alleviate consumer fears as regards food quality along with reduction of dependence on synthetic medication, poultry producers in recent times intensified efforts in searching for natural feed supplements mainly herbs and spices, which have shown some promising results on broiler performance, carcass and quality parameters of meat (Aletor, 1986, Schleicher et al, 1998, Onibi et al, 2000, Gardzielewska et al, 2003and Lipinski et al, 2019. A variety of herbs, including but not limited to Aloe vera, garlic (Allium sativum), ginger (Zingiber officinale), onions (Allium cepa), roselle (Hibiscus sabdariffa), thyme (Thymus vulgaris) have been widely utilized by humans in the diet and for maintenance of good health because of their medicinal values (Freeman and Kodera, 1995).…”

Consequent upon growing awareness of consumers about the use of antibiotics and other synthetic chemicals which may pose health risks in chicken production, it has become imperative for poultry producers to find natural and less hazardous substitutes to replace these chemicals. Therefore, this study was designed to investigate the influence of garlic (Allium sativum), ginger (Zingiber officinale) and roselle (Hibiscus sabdarifa) supplements at 1% inclusion level in broiler chicken diets on performance and carcass characteristics. A total of 150, one day old Arbor acres broiler chicks were obtained and used for the experiment. Five identical diets were formulated such that diet 1 (Negative control) had no antioxidant supplementation while diets 2, 3, 4, and 5 (positive control) were each supplemented with 1% of dried Allium sativum (AS), Zingiber officinale (ZO), Hibiscus sabdarifa (HS), and 200mg/kg vitamin E.The chicks were randomly divided into fifteen groups of ten birds each in a Completely Randomized Design. Each group was randomly assigned to one of the replicates of the dietary treatments, to have a total of 30 chicks per treatment. Average daily feed intake (ADFI), average daily weight gain (ADWG), and feed conversion ratio (FCR) were measured. Apparent nutrient retention, haematological parameters, blood cholesterol, and carcass characteristics were also determined. The ADWG and FCR were not significantly affected by the supplements. However, the birds fed AS supplemented diet had significantly (p<0.05) higher feed intake, than those fed HS supplemented diet but similar to birds in the negative control. Dry matter retention was not significantly affected in any of the treatments. It was observed that birds fed the AS supplemented diet had significantly higher (p<0.05) crude protein, crude fibre, and ether extract retention than all other treatments. Dressed weight was significantly (p<0.05) higher (76.42%) in birds fed AS supplemented diets. In conclusion, the Allium sativum, Zingiber officinale, and Hibiscus sabdarifa supplements in the chicken diets did not adversely affect performance. However, it was noted that the Allium sativum supplemented diets elicited better performance in terms of nutrient retention and dressed weight of carcass. Suite à la sensibilisation croissante des consommateurs à l'utilisation d'antibiotiques et d'autres produits chimiques synthétiques qui peuvent présenter des risques pour la santé dans la production de poulet, il est devenu impératif pour les producteurs de volaille de trouver des substituts naturels et moins dangereux pour remplacer ces produits chimiques. Par conséquent, cette étude a été conçue pour étudier l'influence des suppléments d'ail (Allium sativum), de gingembre (Zingiber officinale) et de roselle (Hibiscus sabdarifa) à un niveau d'inclusion de 1% dans les régimes alimentaires pour poulets de chair sur les performances et les caractéristiques de la carcasse. Un total de 150 poussins de chair Arbor acres âgés d'un jour ont été obtenus et utilisés pour l'expérience. Cinq régimes identiques ont été formulés de telle sorte que le régime 1 (témoin négatif) n'avait pas de supplémentation en antioxydants tandis que les régimes 2, 3, 4 et 5 (témoin positif) étaient chacun supplémentés avec 1% d'Allium sativum (AS) séché, Zingiber officinale (ZO) , Hibiscus sabdarifa (HS) et 200 mg/kg de vitamine E. Les poussins ont été répartis au hasard en quinze groupes de dix oiseaux chacun dans un plan complètement randomisé. Chaque groupe a été assigné au hasard à l'une des répétitions des traitements diététiques, pour avoir un total de 30 poussins par traitement. La prise alimentaire quotidienne moyenne (PAQM), le gain de poids quotidien moyen (GPQM) et le ratio de conversion alimentaire (RCA) ont été mesurés. La rétention apparente des nutriments, les paramètres hématologiques, le cholestérol sanguin et les caractéristiques de la carcasse ont également été déterminés. Le PAQM et le RCAn'ont pas été significativement affectés par les suppléments. Cependant, les oiseaux nourris avec un régime supplémenté en AS avaient une prise alimentaire significativement (p<0,05) plus élevée que ceux nourris avec un régime supplémenté en HS mais similaire aux oiseaux du contrôle négatif. La rétention de matière sèche n'a été significativement affectée dans aucun des traitements. Il a été observé que les oiseaux nourris avec le régime supplémenté en AS avaient une rétention significativement plus élevée (p<0,05) de protéines brutes, de fibres brutes et d'extraits éthérés que tous les autres traitements. Le poids paré était significativement (p<0,05) plus élevé (76,42 %) chez les oiseaux nourris avec des régimes supplémentés en AS. En conclusion, les suppléments d'Allium sativum, de Zingiber officinale et d'Hibiscus sabdarifa dans l'alimentation des poulets n'ont pas affecté négativement les performances. Cependant, il a été noté que les régimes alimentaires complétés par Allium sativum induisaient de meilleures performances en termes de rétention des nutriments et de poids habillé de la carcasse.
