Supra-nutritional vitamin E supplementation for 28days before slaughter maximises muscle vitamin E concentration in finisher pigs

Abstract: A 4 × 3 factorial experiment (n=8 pigs per treatment combination) was conducted with 96 female Landrace x Large White pigs to examine the required level of dietary vitamin E and optimum feeding duration before slaughter to maximise muscle vitamin E content in the Longissimus thoracis et lumborum (LTL) muscle. The respective factors were four dietary levels of vitamin E (supplemented as dl--tocopheryl acetate; 35, 300, 500, and 700 IU/kg) and three feeding durations (14, 28 and 42 days before slaughter). Vitam… Show more

“…The 3-wk supplementation should have been sufficient to enhance tissue stores of VE. For example, the plasma and muscular VE reached 80% of the maximum concentration in pigs after a 2-wk supplementation with VE (35 IU/kg vs 300 IU/kg) [ 23 ]. Indeed, the HiVE diet reduced blood ROMs concentrations by 20% in the pigs housed under TN conditions, suggesting the 200 IU/kg VE is superior to the dietary VE concentration recommended by NRC [ 12 ] in neutralizing free radicals when pigs are in normal physiological status.…”

“…Visual appearance of fresh meat influences a consumer’s decision to buy a particular meat product, and consumers usually discriminate against surface discoloration of meat. Enhanced meat color through dietary vitamin E supplementation has been demonstrated in swine ( Kim et al, 2015 ), beef ( Sherbeck et al, 1995 ) and poultry ( Rey et al, 2015 ). In the present study, vitamin E supplementation increased redness of meat whereas decreased lightness of thigh.…”

“…Дальнейшее увеличение содержания витамина Е в мышцах уже не происходило. Сообщалось также, что синтетический токоферол (смесь восьми соединений, не представленных в природе) способен замещать в организме животных природный токоферол (4,7,9,(14)(15)(16)(18)(19)(20)(21)(22)(23)(24)(25).…”

“…В 13 работах представлены данные по динамике накопления продуктов окислительной порчи при хранении как мяса, так и готовых продуктов из мяса от животных, в рацион которых вводили витамин Е в количестве от 10 до 700 мг/кг корма (2,5,7,10,11,15,16,20,21,25,27,29,30). Результаты этих работ свидетельствовали о торможении развития окислительных процессов в мясе и мясной продукции при продолжительном (от 28 сут) применения токоферола в период откорма.…”
