“…The addition of α-tocopherol increased the α-tocopherol in breast and thigh muscles, but the addition of γ-tocopherol increased only the γ-tocopherol levels. The α-tocopherol concentration in the breast muscles was higher than that in our experiment, and higher than that found in broilers at the same rate by Pompeu et al [34] based on a meta-analysis. Compared to egg yolk, the muscles of chickens, especially the breast, are a poor source of vitamin E. Although there is a close relationship between vitamin E and the fat content, the differences among tissues and organs are attributed to the genetically determined control of the vitamin E concentration in different categories of poultry, organs and products.…”

The aim of the study is to determine the effect of hemp seed (HS) of the nonpsychotropic variety Futura and extruded flaxseed (EF) in the diet of cockerels on cockerel growth performance, breast muscle and liver α- and γ-tocopherol concentrations, breast muscle fatty acid concentrations and tibia strength. Five hundred and forty one-day-old male Ross 308 cockerels are equally allocated into six groups. Each group has three replicates of 30 cockerels in pens with litter. The formulated diets are isoenergetic (the metabolisable energy ranged from 12.4 to 12.8 MJ/kg) and isonitrogenic (the protein concentration ranged from 209.7 to 210.9 g/kg) and provided ad libitum. During the experiment, which lasts 35 days, the control group is fed a diet without EF or HS. Rapeseed oil was the lipid source in the control diet. The diet for the second group contains EF at 60 g/kg, the diet for the third group contains HS at 40 g/kg, and the diets for the fourth to sixth groups contain HS and EF at 30 and 60 g/kg, 40 and 60 g/kg and 50 and 60 g/kg, respectively. At the end of the experiment, 15 cockerels of average weight are slaughtered per group, and the breast muscle, liver and tibia bone are dissected for chemical analyses. The all dietary combination of HS and EF increases (p < 0.001) cockerel body weight (2375–2493 g) more than HS alone (2174 g) or EF alone (2254 g). A similar finding is observed for the diet composition and tocopherol content in the liver, but the doses of HS required to achieve this effect are higher (40 and 50 g/kg). The tocopherol content in the breast muscle is not influenced by the diet. The dietary combination of 60 g/kg EF and 40 g/kg HS results in the most promising findings of the experiment, since it leads to the lowest n-6/n-3 polyunsaturated fatty acids ratio (p < 0.001; 1.75). Incorporation of HS into the diet increases cockerel tibia strength (p < 0.001), which is of great practical importance due to the frequent occurrence of limb fractures. To conclude, the dietary supplementation with 40 g/kg HS and 60 g/kg EF improves cockerel performance, meat and bone quality and deposition of α-tocopherol in the liver.

“…Vitamin C and E also function as antioxidants that can reduce production stress and improve the carcass quality of the animal. A recent meta-analysis indicated that meat quality and immune response of male broiler chickens could be improved by dietary vitamin E supplementation 86 . However, Lin and Chang 87 suggested that moderate supplementation of vitamin E enhanced immune responses to selective antigens but excessive vitamin E depressed specific immune response in cockerels fed a cornsoyabean meal-based diet.…”

A growing global concern of antibiotic use in poultry diets due to its potential adverse effects on birds and human health, food safety and the environment has led to a complete ban or restricted use in some countries, and, at the same time, expanding options for the use of alternative feed additives. Multiple, rather than a single additive may replace antibiotic growth promoters (AGPs) in poultry. Blending of feeding additives and hygienic farm management, vaccination and biosecurity may help achieve good intestinal health, stabilise enteric ecosystems and result in sustainable and cost effective production performance of birds. Moreover, controlling unsolicited ingredients at the production level must have the support of different markets responsible for the supply of safe and quality poultry products for consumers. This requires the further increase and diversification of value added poultry products and the expansion of their markets through strategic planning and gradual limitation of live bird markets. More research is warranted in order to explore suitable, reliable and cost effective alternatives to AGPs for commercial use, and strategic poultry value chain development.

“…The higher concentration of α-tocopherol in meat is helpful in preservation, as it protects sensitive compounds, such as UFA and PUFA, from oxidation. The increased Vit E concentration in the broiler diet increased Vit E content and decreased lipid peroxidation in meat, thus highlighting the benefits of additional Vit E for maintaining fat quality in broiler meat (38). Our recent findings report an effect of Vit E on lipid oxidation in broiler meat during the postmortem storage, and a significant reduction of MDA production in meat observed by adding 50-150 kg/mg Vit E with the oil blend of PO and SO and L-Arg (22).…”

“…Vit E is particularly essential for the inhibition of fatty acid oxidation. Fatty acids can act as immunoregulatory particles that facilitate membrane fluidity, cellular communication, and second messenger elaboration; furthermore, the inhibitory action of Vit E on the stability of fatty acids may itself be immunoregulatory (38).…”

This study set out to examine the combined effects of the supplementation of a dietary palm oil (PO) and sunflower oil (SO) blend, 0. 25% L-Arginine (L-Arg), and different levels of vitamin E (Vit E) on growth performance, fat deposition, cytokine expression, and immune response in broilers. A total of 216 1-day-old male broiler chicks (Cobb500) were randomly distributed into six dietary groups as follows: Diet 1: 6% palm oil (negative control); Diet 2: PO and SO blend (4% palm oil and 2% sunflower oil) + 0.25% L-Arg
