Replacement of Vitamin E by an Extract from an Olive Oil by-Product, Rich in Hydroxytyrosol, in Broiler Diets: Effects on Liver Traits, Oxidation, Lipid Profile, and Transcriptome. Antioxidants (Basel) 2023; 12:1751. [PMID: 37760054 PMCID: PMC10525107 DOI: 10.3390/antiox12091751] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 09/06/2023] [Accepted: 09/06/2023] [Indexed: 09/29/2023] Open
Abstract
The study examines the effect of replacing vitamin E (VE) with a liquid obtained from alpeorujo, an olive oil by-product rich in hydroxytyrosol (HT), as an antioxidant in broiler chicken feeds on the gene expression, lipid profile, and oxidation in the liver. There were five diets that differed only in the substitution of supplemental VE (0 to 40 mg/kg with differences of 10 mg/kg) by HT (30 to 0 mg/kg with differences of 7.5 mg/kg). A linear decrease (p < 0.05) in α-tocopherol concentration in the liver was observed with the replacement of VE by HT. There were no significant changes in triglyceride, cholesterol, or TBARS concentrations. The hepatic transcriptome showed 378 differentially expressed genes between broilers fed HT15 (20 mg/kg VE and 15 mg/kg HT) and HT0 (40 mg/kg VE) diets (p < 0.05 and fold change less or higher than 1.3). Significant changes in cell cycle, cell nucleus activity, neuroactivity, and necroptosis pathways and functions were observed. It is concluded that the olive oil by-product, rich in HT, could be used to spare VE as an antioxidant in broiler diets without affecting liver lipid and TBARS concentrations. The differential gene expression analysis showed a potential role of olive polyphenols in enhancing the chicken immune response.

Vitamin E Supplementation Enhances Lipid Oxidative Stability via Increasing Vitamin E Retention, Rather Than Gene Expression of MAPK-Nrf2 Signaling Pathway in Muscles of Broilers. Foods 2021; 10:foods10112555. [PMID: 34828836 PMCID: PMC8624736 DOI: 10.3390/foods10112555] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2021] [Revised: 10/17/2021] [Accepted: 10/21/2021] [Indexed: 12/02/2022] Open
Abstract
Dietary vitamin E (VE) supplementation is a method to produce VE-enriched meat and improve meat lipid oxidative stability. We aimed to study the effect of the VE supplementation duration on meat lipid oxidative stability, VE retention, and antioxidant enzymes’ activity, and explore its relationship with the mitogen-activated protein kinases (MAPK)-nuclear factor-erythroid 2-related factor 2 (Nrf2) signaling pathway in broilers slaughtered after electrical stunning. A total of 240 male 18-day-old Arbor Acres Plus broilers were distributed to four treatments, with six replicates in each treatment, and ten broilers per replicate. Broilers were fed with a basal diet (no supplementation of VE) or VE diet (200 IU/kg VE, DL-α- tocopherol) for one (W1), two (W2), or three (W3) weeks before electrical stunning (130 mA, 60 Hz, for 1s) and slaughter. The VE retention was positively and linearly affected (p < 0.01) by the VE feeding duration at one to three weeks before slaughter, and negatively (all p < 0.01) related to the thiobarbituric acid reactive substance (TBARS) content in both breast and thigh muscles at d 0, d 2, and d 6 postmortem. The VE retention was negatively (p < 0.05) related to the gene expression of c-Jun N-terminal kinases 1 (JNK1) and 2 (JNK2), Nrf2 in breast muscles, and JNK1 and p38 MAPK in thigh muscles. In conclusion, dietary vitamin E supplementation at 200 IU/kg for three weeks before electrical stunning and slaughter improved lipid oxidative stability via increasing VE retention, rather than the regulation by gene expression of the MAPK-Nrf2 signaling pathway in skeletal muscles of broilers.

Abstract
The aim of the study was to determine the effect of dietary vitamin E level on cholesterol and vitamin E content and fatty acid profile in broiler chicken breast and leg muscles. Chickens (420 cocks) were randomly divided into two feeding groups (210 birds each). The control group was fed with standard diet containing 44 mg kg−1 of vitamin E, whereas the experimental group was supplemented with extra 200 mg kg−1 of vitamin E. The dietary addition of vitamin E caused a significant increase in its content in the muscles, with a higher value noted in the leg muscles. Meat of chickens fed with the higher dose of vitamin E was also characterized by a lower cholesterol level. The addition of vitamin E as well as type of the muscles had a significant effect on the fatty acid profile and values of atherogenicity (AI) and thrombogenicity (TI) indices. The recorded increase in the content of n-3 polyunsaturated fatty acids (PUFAs) and a decrease in the n-6/n-3 fatty acid ratio indicate a positive effect of vitamin E on the fatty acid profile. In turn, lower values of AI and TI in leg muscles of chickens with a high intake of vitamin E prove the beneficial fatty acid profile in these muscles upon such supplementation.

Abstract
The present study was conducted to compare the supplementation of natural (D-α-tocopherol) and synthetic (DL-α-tocopherol acetate) vitamin E on the growth performance, meat quality, muscular antioxidant capacity and genes expression related to oxidative status of broilers. A total of 144 1 day-old Arbor Acres broiler chicks were randomly allocated into 3 groups with 6 replicates of 8 birds each. Birds were given a basal diet (control group), and basal diet supplemented with either 20 IU D-α-tocopherol or DL-α-tocopherol acetate for 42 days, respectively. The results indicated that treatments did not alter growth performance of broilers (p>0.05). Compared with the control group, concentration of α-tocopherol in the breast muscle was increased by the supplementation of vitamin E (p<0.05). In the thigh, α-tocopherol content was also enhanced by vitamin E inclusion, and this effect was more pronounced in the natural vitamin E group (p<0.05). Vitamin E supplementation increased the redness of breast (p<0.05). In the contrast, the inclusion of synthetic vitamin E decreased lightness of thigh (p<0.05). Dietary vitamin E inclusion reduced drip loss at 24 h of thigh muscle (p<0.05), and this effect was maintained for drip loss at 48 h in the natural vitamin E group (p<0.05). Broilers given diet supplemented with vitamin E showed decreased malondialdehyde (MDA) content in the breast (p<0.05). Additionally, natural rather than synthetic vitamin E reduced MDA accumulation in the thigh (p<0.05). Neither natural nor synthetic vitamin E supplementation altered muscular mRNA abundance of genes related to oxidative stress (p>0.05). It was concluded that vitamin E supplementation, especially the natural vitamin E, can enhance the retention of muscular α-tocopherol, improve meat quality and muscular antioxidant capacity of broilers.

Abstract
The effect of by-products of oriental medicinal plants (OMP; T1) containing 0.03% herb extracts (T2) or 0.1% aminolevulinic acid (T3) on the production performance of swine during the finishing period and on its meat quality were investigated. No significant differences were found in the weight gain, feed intake and feed conversion rate among the tested groups (P > 0.05). But the treated group showed higher (P < 0.05) moisture and ash and lower protein than the control group. The T3 group showed a lower meat cholesterol content (38.42 mg/100 g) compared to the other groups (P < 0.05). The vitamin E content of the muscle in the treated groups was higher compared to the control group. No antibiotic content was detected in all treated and control samples. The values of the volatile basic nitrogen (VBN) and thiobarbituric acid reactive substance (TBARS) of the treated groups were significantly lower (P < 0.01) than the control group. The treated groups had significantly better (P < 0.05) sensory-test scores for color, flavor, off-flavor and total acceptability compared to the control group.

Abstract
This study was designed to evaluate the effects of dietary treatment, packaging, and irradiation singly or in combination on the oxidative stability of broiler chicken thigh meat. A total of 120 four-week-old chickens were divided into 12 pens (10 birds/pen), and 4 pens of broilers were randomly assigned to a control oxidized diet (5% oxidized oil) or an antioxidant-added diet [500 IU of vitamin E + 200 mg/kg of butylated hydroxyanisole (BHA)] and fed for 2 wk. After slaughter, thigh meats were separated, ground, packaged in either oxygen-permeable or oxygen-impermeable vacuum bags, and irradiated at 0 or 3 kGy. Lipid oxidation (TBA-reactive substances), protein oxidation (carbonyl), and color of the meat were measured at 1, 4, and 7 d of refrigerated storage. The lipid and protein oxidation of thigh meats from birds fed the diet supplemented with antioxidants (vitamin E + BHA) was significantly lower than the lipid and protein oxidation of birds fed the control diet, whereas the lipid and protein oxidation of broilers fed the oxidized oil diet was higher than that of birds fed the control diet. Vacuum packaging slowed, but irradiation accelerated, the lipid and protein oxidation of thigh meat during storage. Dietary antioxidants (vitamin E + BHA) and irradiation treatments showed a stronger effect on lipid oxidation than on protein oxidation. A significant correlation between lipid and protein oxidation in meat was found during storage. Dietary supplementation of vitamin E + BHA and the irradiation treatment increased the lightness and redness of thigh meat, respectively. It is suggested that appropriate use of dietary antioxidants in combination with packaging could be effective in minimizing oxidative changes in irradiated raw chicken thigh meat.

Abstract
The objective of this study was to compare the effect of 2 esters of alpha-tocopherol, all-rac-alpha-tocopherol acetate and RRR-alpha-tocopherol succinate (d-alpha-TOS) on growth and immunity in broiler chicks. Three hundred twenty 1-d-old commercial Arbor Acres broilers were randomly distributed to 4 treatments, each of which had 8 pens of 10 chicks per pen. Birds in the control group were fed with the diets supplemented with 30 mg/kg of all-rac-alpha-tocopherol acetate or the basal diet with d-alpha-TOS supplementation at 10 mg/kg (TOS1 group), 30 mg/kg (TOS2 group), and 50 mg/ kg (TOS3 group), respectively, for 42 d. The results showed that there was no significant difference (P > 0.05) in BW gain, feed intake, or G:F among the treatments. Significant positive correlations existed between dietary supplemental alpha-TOS levels and plasma (R(2) = 0.9831, P < 0.01) or hepatic (R(2) = 0.9336, P < 0.05) alpha-tocopherol concentrations and a negative correlation with plasma (R(2) = 0.9487, P < 0.05) or hepatic (R(2) = -0.9901, P = 0.0518) malondialdehyde levels. The concentrations of serum glutathione (GSH) were highest at 50 mg/kg at 42 d of age (P < 0.05), and hepatic GSH was significantly higher at 30 and 50 mg/kg compared with the other groups. Marked enhancement of splenic T- and B-lymphocyte proliferation occurred in group TOS3 as compared with the other groups. The study suggests that the immunoenhancement effect observed in broilers fed additional d-alpha-TOS between 30 and 50 mg/kg might result from increased retention of alpha-tocopherol and reduction in lipid peroxidation, as evidenced by the decrease in malondialdehyde and the increase in GSH.

Abstract
An experiment was designed to assess the effect of dietary unsaturated fat inclusion level on alpha-tocopherol apparent absorption and deposition in broiler chickens at 2 ages (20 and 39 d). The dietary fat was a mixture of linseed and fish oil, rich in polyunsaturated fatty acids (PUFA). The experimental treatments were the result of 4 levels of supplementation with alpha-tocopheryl acetate (0, 100, 200, and 400 mg/kg; E0, E100, E200, and E400 treatments, respectively) and 4 dietary oil inclusion levels (2, 4, 6, and 8%; O2, O4, O6, and O8 treatments respectively). Almond husk was used as an energy dilutor in the high-fat diets. Apparent absorption of total fatty acids was high in all treatments averaging 88% and was higher with high fat dietary inclusion level. alpha-Tocopheryl acetate hydrolysis and apparent absorption of alpha-tocopherol were similar in both ages and were not affected by fat inclusion level, except for a reduction of the absorption in the low-fat diet (O2) in the E100 treatment at 20 d of age. Despite this lack of differences in hydrolysis and absorption, higher-fat PUFA diets induced lower concentrations of free alpha-tocopherol in the excreta, at high alpha-tocopherol doses, suggesting an increase in the destruction of alpha-tocopherol by lipid oxidation in the gastrointestinal tract. Similarly, total and hepatic alpha-tocopherol deposition was lower in the birds fed high-PUFA diets in the E200- and E400-supplemented birds, possibly due to a destruction of vitamin E when protecting these PUFA from lipid peroxidation. alpha-Tocopherol concentration in liver and, to a lesser extent, in plasma was a useful indicator of the degree of response of this vitamin to different factors that can affect its bioavailability; however, in the present experiment, CV were too high to use liver and plasma concentrations as estimators of total body vitamin E.

Abstract
1. A trial was conducted to examine the effects of dietary vitamin E content, age and sex on haematological indices and liver enzymes of Japanese quails. A total of 800 1-d-old quail chicks were assigned at random into 4 equal groups and fed on starter and layer diets containing 0, 1, 5 or 10 times the NRC recommended supplements of vitamin E. No selenium was added to the basal deficient diets; the other diets were supplied with 0.2 mg selenium/kg diet. 2. The investigation covered the age span of 3 to 12 weeks in female and male birds. Blood samples were collected at 3-week intervals and tested for haematological indices (erythrocyte count; leucocyte count; susceptibility of erythrocytes to haemolysis; haemoglobin concentration (Hb); packed cell volume (PCV); and mean corpuscular volume (MCV)) and liver enzymes (aspartate transaminase, AST, and glutathione peroxidase, GSH-Px). 3. The significant differences between the 4 dietary treatments indicated that as the levels of selenium and/or vitamin E increased, the percentage of erythrocytes haemolysed and AST activity decreased, whereas Hb and GSH-Px concentrations increased. 4. Differences between age groups showed that older quails had higher erythrocyte susceptibility to haemolysis, higher AST levels and but lower erythrocyte count and PCV. 5. Females had lower erythrocyte haemolysis and higher Hb concentrations than males. 6. The interaction between dietary groups and age groups revealed that the differences between age groups were reduced as the level of selenium and/or vitamin E increased, leading to similar group means over the age period of study. 7. In conclusion, NRC recommended supplements of vitamin E (12 and 25 mg/kg diet) were not adequate. Doses equal to, at least, 5 times that recommended were advised to improve GSH-Px (index of antioxidant status) and Hb concentrations.

Abstract
The effects of maternal vitamin E supplementation on the antioxidant status of chicks were investigated. Female breeder chicks were fed corn-soybean growing diets without supplemental vitamin E for a 17-wk developmental period. After 17 wk, the birds were randomly assigned to 5 treatments and fed corn-soybean diets supplemented with 0, 40, 80, 120, and 160 mg/kg vitamin E (all-rac-alpha-tocopherol acetate), respectively. Blood samples were collected and pullets were artificially inseminated at 35 wk of age. Eggs laid beginning on d 2 after insemination were placed in an incubator. At the time of hatching, 12 chicks from each treatment were randomly sampled and killed. Livers and brains of chicks were collected for the subsequent evaluation of antioxidant status. Plasma vitamin E concentrations increased linearly (P < 0.001; r = 0.997) with the increase in supplemental vitamin E, but those in egg yolk reached a plateau at 120 mg/kg supplemental vitamin E. The malondialdehyde (MDA) concentration, an indicator of lipid peroxidation, of chick brain decreased linearly (P < 0.01; r = -0.909) with the increase in supplemental vitamin E. Pullets given 160 mg/kg supplemental vitamin E had lower plasma MDA concentrations than those given 0 mg/kg (P < 0.05). Similar results were found for the reactive oxygen species levels, an indicator of oxidative stress, of chick brain and liver. For antioxidant enzymes, chicks of pullets given 120 mg/kg supplemental vitamin E had higher (P < 0.05) activities of liver catalase than those given 0-80 mg/kg. Chicks of pullets given 160 mg/kg supplemental vitamin E had higher (P < 0.05) activities of brain superoxide dismutase than those given 0-40 mg/kg. These results indicated that maternal supplementation with high levels of vitamin E (120-160 mg/kg) enhances antioxidant capability and depresses oxidative stress in chicks.

Abstract
Two trrials were conducted to define temporal changes in plasma D-alpha-tocopherol (AT) caused by infection with Eimeria maxima in chickens that consumed either low (25 ppm) or high (225 ppm) levels of dietary DL-alpha-tocopheryl acetate (VE-AC) from 1 day of age. In both trials, rates of weight gain were depressed between days 5 and 7 post-inoculation (PI) and were not influenced by the level of dietary VE-AC. Plasma AT was consistently depressed at 5 and 7 days PI in chickens consuming either level of dietary VE-AC. The pattern and degree of plasma AT depression correlated with those of plasma carotenoids. Plasma levels of NO2- + NO3- were significantly increased at 5 and 7 days PI. In trial 1, the average increase during that period was not as high in chicks consuming 225 ppm VE-AC, but in trial 2, diet had no effect on the degree of increase. Also, there were no consistent effects of dietary VE-AC on lesion scores or amount of oocysts shed. These results are in general accord with findings of earlier experiments, and we conclude that feeding high levels of VE-AC to broiler chicks from 1 day of age is not effective in mitigating the pathology, including weight gain depression and development of mucosal lesions, during E. maxima infections or in modifying immune response events associated with phagocytosis as indexed by plasma NO2- + NO3-. The likely basis for the ineffectiveness of feeding this fat-soluble form of vitamin E is that it is malabsorbed during E. maxima infection in the same manner as carotenoids and becomes less biologically available to infected tissues during the acute phase of infection.

Abstract
The aim of the study was to contribute to the discussion of overdosing vitamin E in laying hens. A total of 45 laying hens, divided into 5 groups were fed diets supplemented with either 0; 100; 1000; 10,000 or 20,000 mg dl-alpha-tocopheryl acetate/kg diet over a period of 10 weeks. Concentrations of vitamins A and E were measured in plasma, various tissues and egg yolk. Furthermore egg yolk colour and some carotinoids were measured in egg yolks. None of the vitamin E doses significantly influenced performance of the hens. As expected, vitamin E concentration in plasma, all tissue samples and egg yolk was significantly increased with increasing tocopherol content in the diet. The egg yolk showed the highest vitamin E concentration, followed by liver and muscles. Feeding 1000 mg alpha-tocopheryl acetate per kg diet resulted in an increase of vitamin A concentration in the liver. Very high doses (10,000 and 20,000 mg/kg diet) significantly decreased retinol concentration in the liver and egg yolk, as well as carotinoid concentration in the egg yolk. The lower carotinoid concentration in egg yolk resulted in a decreased intensity of egg yolk colour. A prooxidative and/or competitive effect of very high doses of vitamin E with other fat soluble substances has been discussed.

Abstract
In two trials, broiler chickens, processed similarly to those placed in commercial operation, were fed, from 1 d of age, a range (13 to 200 ppm) of DL-alpha-tocopheryl acetate (VE-AC) levels, and the effects on the pathology of Eimeria maxima infections were assessed at 6 d postinoculation (PI). In Trial 1, dietary levels of VE-AC had little significant effect on variables characterizing pathology except for the number of oocysts shed, which was significantly increased in chicks treated with higher VE-AC levels. The infection was judged to be mild based on moderate lesion scores (2.2+/-0.2), lack of significant effects on weight gain (7+/-1.6% decrease), moderate reduction in plasma carotenoids (21+/-2%) and small increases in plasma NO2-+NO3- (141+/-12%). In uninfected and infected chickens, plasma alpha-tocopherol (AT) increased with dietary levels of VE-AC; however, E. maxima infection caused a fairly constant decrease in AT of 35.3+/-3.2% across these levels. Plasma gamma-tocopherol (GT) levels were unaffected by dietary VE-AC or E. maxima infection. In Trial 2, pathology, again, was relatively unaffected by dietary VE-AC level. The infection was judged to be severe based on lesion scores (3.5+/-0.1), reduction in weight gain (30.7+/-3%), plasma carotenoids (72.4+/-1.5%), uric acid (16.3+/-3.4), albumin (37.8+/-2.8%), large increases (261+/-8%) in plasma NO2-+NO3-, and high numbers of oocysts shed per chick (4.12+/-0.4 x 10(7)). Plasma AT again increased with increasing dietary VE-AC levels in uninfected and infected chicks, but the mean decrease across VE-AC levels caused by E. maxima infection was 73.14+/-3.3%. GT levels were erratic and unrelated to dietary VEAC or infection. Thus, in processed broiler chickens, high dietary VE-AC did not prevent or lessen the pathology caused by mild or severe infections with E. maxima. The main effect of E. maxima infection appeared to be reduction in plasma AT levels. We postulate that this reduction may be due to malabsorption of AT, which results from physical damage to the absorptive mucosa, reduction in esterases required to hydrolyze the VE-AC, and a generalized lipid malabsorption, preventing movement of the free AT to circulating blood and infected tissues.

Abstract
The influence of fish oil (highly unsaturated) and beef tallow (highly saturated) with vitamin E (100 IU/kg) supplementation on the antioxidant status of broiler chicken cockerels was investigated. Chicks were fed a control diet with no added fat, 40 g/kg each of fish oil and beef tallow diets, respectively, from 11 to 42 days of age. Tocopherol concentration and the rate of lipid peroxidation, thiobarbituric acid reactive substance (TBARS) in liver, fatty acid composition of the liver lipids, blood serum total antioxidant status (TAS), and reduced glutathione (GSH) content were determined. Vitamin E supplementation of the diet increased liver alpha-tocopherol content in chicks regardless of the type of dietary fat. Fish oil diet resulted in higher liver TBARS value while beef tallow diet showed lower values compared to the control diet. Vitamin E supplementation reduced liver TBARS as well as serum GSH, and raised serum TAS for all diets. Serum GSH was the same for vitamin E supplemented diets regardless of the fat supplement. Fish oil diets resulted in a significant increase in hepatic lipid n-3 PUFA content. A significant positive correlation was found between liver TBARS and n-3 PUFA content. No relationships were established, however, between liver TBARS and n-6 PUFA or saturated fatty acids. The results suggest that feeding oils rich in n-3 PUFA increases tissue concentration of these fatty acids, consequently increasing tissue lipid peroxidation and reducing the antioxidative status of broiler chickens. Supplementing high levels of vitamin E with such oils may increase tissue oxidative stability. Serum TAS or GSH may be used as a measure of antioxidative status in chickens.

Abstract
The beneficial health-promoting effects of the long-chain polyunsaturated fatty acids (PUFA) of the n-3 series make them important constituents of human and animal diets. The effects of tuna oil or a combination of tuna oil with an increased level of vitamin E on the fatty acid profile and vitamin E distribution in tissues taken from cockerels were studied. Male chickens (Ross broiler breeders), penned on white wood shavings, were allocated into one of three groups with 12 birds per group and were fed from 10 wk of age on a commercial diet supplemented with 3% corn oil (control) or with 3% Tuna orbital oil (TO). Vitamin E was added at the rate of 40 mg/ kg, except in the third group in which the birds received a diet containing TO (3%) supplemented with 160 mg/kg vitamin E (TO+E). At 72 wk of age, the cockerels were killed, and tissues (liver, testes, heart, lung, kidney, spleen, thigh muscle, pancreas, internal fat, cerebellum, and cerebrum) were dissected for lipid and vitamin E analyses. Inclusion of TO in the cockerel diets significantly (P < 0.01) increased docosahexanoic acid (DHA) proportions in the major lipid fractions of the tissues with the brain being more resistant to lipid manipulation compared with the other tissues. Tissue enrichment with DHA took place at the expense of a decrease of n-6 PUFA. In the DHA-enriched tissues, vitamin E level decreased (P < 0.05), and susceptibility to peroxidation (TBARS accumulation) significantly (P < 0.01) increased. High vitamin E supplementation (160 mg/kg) in combination with TO prevented decrease of alpha-tocopherol concentration in the tissues and normalized or even increased their resistance to lipid peroxidation. There was tissue-specificity in response to dietary vitamin E supplementation; the liver was most responsive and the cerebellum was most resistant to vitamin E manipulation.

Abstract
The aim of this investigation was to contribute to the problem of overdosing vitamin E. A total of 80 laying hens, divided into 5 groups, were fed diets supplemented with 0, 100, 1000, 10,000 and 20,000 mg/kg vitamin E over a period of 20 weeks within two brooding tests. Laying performance and hatching parameters were registered. All vitamin E doses did not significantly influence health and performances of hens. Vitamin E content of eggs increased from 1 to 4, 21, 46 and 51 mg per egg with vitamin E supplementation. High doses decreased oxidative stability of abdominal fat, vitamin A concentration of liver and egg yolk colour. In both tests vitamin E supplements of 10,000 and 20,000 mg/kg feed resulted in a decrease of living hatched chicken, which demonstrated an adverse effect. Further studies seem to be necessary to explain the effect.

Abstract
Este experimento foi realizado com o objetivo de avaliar o efeito da suplementação de diferentes níveis de vitamina E (NVE) na dieta sobre o desempenho de frangos de corte de um a 42 dias de idade, e sobre a concentração de alfa-tocoferol (AT) na carne de peito das aves aos 45 dias de idade. Foram alojados 480 pintos de um dia, da linhagem Ross, em 16 boxes de 3,00× 2,20m, com 30 aves de ambos os sexos em cada boxe. A ração e a água foram fornecidas ad libitum. As aves receberam uma dieta inicial (1 a 21 dias), com 21,2% de PB e 2934kcal de EM/kg, e uma dieta de crescimento (22 a 42 dias), com 18% de PB e 3035kcal de EM/kg. Ambas as dietas foram suplementadas com quatro NVE: 25, 250, 500 e 750mg/kg. O delineamento experimental foi o inteiramente ao acaso, constituído de quatro tratamentos (NVE), com quatro repetições, cada uma com 30 aves. Verificou-se que o peso corporal, o ganho de peso e a conversão alimentar aos 42 dias de idade foram significativamente influenciados (P<0,05) pelos NVE utilizados na dieta. Houve aumento linear para peso e ganho de peso, e melhoria linear da conversão alimentar à medida que se elevou o nível da suplementação de vitamina E (VE) da dieta. O consumo de ração e a viabilidade não foram influenciados (P>0,05) pelos NVE. Observou-se efeito quadrático (P<0,05) do NVE na dieta sobre a deposição de AT na carne de peito das aves, sem diferença entre sexos. Máxima concentração de AT foi verificada na carne de peito de aves que foram alimentadas com dieta de 500mg de VE/kg. Desse modo, conclui-se que para cada aumento de 25mg de VE/kg na dieta, espera-se um aumento de 5,49g no peso corporal, melhoria de 0,0038 pontos na conversão alimentar, e um aumento de 8,57mig de AT/g de carne de peito de frangos de corte.

Abstract
1. The effect of supplementing the diet of the parent hen with vitamin E on the vitamin E content of the yolk and of embryonic and neonatal tissues was evaluated and the effects of elevated tissue concentrations of vitamin E on peroxidation susceptibility was examined. 2. Laying hens (Ross 1 broiler-breeder strain) were maintained on diets containing either 147 (control diet) or 365 (high vitamin E diet) microg vitamin E/g feed. 3. In the day-16 embryo, the concentrations of of vitamin E in the yolk sac membrane, liver, brain and lung were respectively 5.0, 4.3, 1.7 and 5.6 times greater for those derived from the hens on the high vitamin E diet compared with those from the control group. 4. In the day-old chick, the concentrations of vitamin E in the yolk sac membrane, liver, brain and lung were respectively 14.8, 2.8, 3.0 and 5.1 times greater for those derived from hens on the high vitamin E diet compared with those from the control group. 5. Homogenates of tissues from the day-old chick were incubated in the absence and presence of Fe2+ in order to determine the extent of spontaneous and iron-stimulated peroxidation as measured by the generation of thiobarbituric acid reacting substances. For the chicks derived from hens on the control diet, the brain was markedly more susceptible to both spontaneous and iron-stimulated peroxidation than were the other tissues. Tissues from the chicks derived from the hens on the high vitamin E diet exhibited significantly reduced susceptibilities to peroxidation. In particular, the susceptibility of the brain was reduced to the same level as that of the other tissues. 6. It is concluded that the high peroxidative susceptibility of the chick's brain can be normalised by supplementation of the parent hen with vitamin E.

Abstract
1. Day-old turkey poults (n = 14) were randomly divided into 2 groups (n = 7) and fed diets containing 20 (E20) and 600 (E600) mg all-rac-alpha-tocopheryl acetate/kg food for 21 weeks prior to slaughter. Following slaughter, breast and leg meat was removed and 4 batches of patties were produced from each. Two of the batches were formed from E20 meat (E20) and E20 plus 1% salt (E20S). Two similar batches were formed from E600 meat (E600) and E600 plus 1% salt (E600S). 2. Patties were fried, cooled and overwrapped with high oxygen-permeable film. Overwrapped patties were displayed in a 4 microC cabinet under fluorescent light (616 lux). Lipid oxidation (TBARS numbers) was determined on d 0, 2, 4, 6, 8 and 10, while taste panels to assess warmed-over flavour (WOF) were carried out on d 0, 2 and 4 of refrigerated (4 degrees C) display. 3. In the case of both leg and breast meat, E600 patties were the least susceptible of the 4 treatment batches to lipid oxidation. Salt had the effect of promoting lipid oxidation, with E20S and E600S patties having higher TBARS numbers than the corresponding patty batches where salt was absent. 4. Taste panel results showed that leg and breast patties formed from the meat of turkeys given alpha-tocopheryl acetate enriched diets developed significantly (P < 0.05) less WOF than those formed from control turkey meat on d 2 and 4 of refrigerated (4 degrees C) display. Patties containing 1% salt generally exhibited a greater degree of WOF than patties without salt. 5. A linear relationship was observed between TBARS numbers and WOF percentages for all batches of leg and breast patties.

1. One-day-old turkey poults (n = 14) were randomised into 2 groups (n = 7) and fed diets containing 20 (E20) and 600 (E600) mg all-rac-alpha-tocopheryl acetate/kg food for 21 weeks prior to slaughter. Two batches were formed from E20 meat (E20) and E20 plus 10 g salt/kg (E20S). Two similar batches were formed from E600 meat (E600) and E600 plus 10 g salt/kg (E600S). 2. The effects of alpha-tocopheryl acetate supplementation and salt addition on the oxidative stability of raw turkey patties was investigated during aerobic and vacuum-packaged refrigerated (4 degrees C) storage. 3. Dietary alpha-tocopheryl acetate supplementation reduced TBARS (thiobarbituric acid reacting substances) numbers for raw overwrapped and vacuum-packaged turkey leg and breast patties. 4. Dietary alpha-tocopheryl acetate had the greatest influence on TBARS numbers for raw overwrapped turkey leg patties. 5. The addition of 10 g salt/kg increased TBARS numbers for overwrapped and vacuum-packaged turkey leg and breast patties. 6. Vacuum-packaged patties remained more oxidatively stable than similarly treated overwrapped patties throughout the experimental period.

Abstract
1. An experiment was carried out with male broiler chicks to evaluate the combined effect of two concentrations of vitamin A (1.032 and 10.32 mg retinyl acetate/kg diet) and two concentrations of vitamin E (0 and 150 mg alpha-tocopheryl acetate/kg diet) on the oxidative stability of the drumstick meat of broiler chickens. The experimental diets were fed from 1 to 42 d of age. The oxidative stability, evaluated by thiobarbituric acid reactive substances (TBARS) values, was determined after 125 d of storage at -18 degrees C. 2. TBARS values were very low and not significantly affected by dietary vitamins A and E or their combinations. However, the TBARS values in the meat of birds fed on the vitamin E-free diets, but not on the vitamin E-supplemented diets, were markedly increased after using an accelerated test of oxidation of the meat lipids by incubation. This resulted in a significant (P<0.001) difference from vitamin E supplementation. Vitamin A, alone or in combination with vitamin E, did not affect TBARS values found after incubation. 3. It is concluded that vitamin A at the concentrations used had no effect on the oxidative stability of the meat, in contrast to the protective effect of vitamin E, and that there is no interaction between the effect of these two vitamins on meat stability.

Abstract
1. The effects of dietary alpha-tocopheryl acetate on the alpha-tocopherol status of chicken plasma and tissues were investigated. The rate of iron-ascorbate-induced lipid peroxidation was also studied. 2. One hundred and forty four chicks were divided into 6 groups: one control group was fed a basal diet of 30 mg alpha-tocopheryl acetate/kg food for the duration of the trial. A supplemental diet of 200 mg alpha-tocopheryl acetate was fed to each of the other 5 groups for 1,2,3,4 or 5 weeks prior to slaughter. 3. Supplementation resulted in an increase in alpha-tocopherol in plasma and all tissues examined. Saturation levels of alpha-tocopherol were observed in plasma after 1 week of feeding and in tissues within 3 to 4 weeks of feeding. 4. Supplementation with alpha-tocopheryl acetate for up to 4 weeks pre-slaughter resulted in significant reductions in susceptibility to induced lipid peroxidation. 5. Overall, the results show that feeding 200 mg alpha-tocopheryl acetate/kg food to chicks for at least 4 weeks prior to slaughter is necessary to optimise muscle content and stability against lipid peroxidation.

Abstract
An experiment was conducted to compare the efficacy of two dietary sources and an injectable form of vitamin E (VE) to improve the VE status of poults. Six of the treatments consisted of a factorial arrangement of three concentrations and two sources of dietary VE. Turkeys in these treatments received 12, 80, or 150 IU of either dl-alpha-tocopheryl acetate or d-alpha-tocopherol (d-alpha-TOC)/kg of diet. The seventh treatment consisted of a single subcutaneous injection of d-alpha-TOC at 1 d of age. Poults in this treatment were subcutaneously injected in the dorsal area of the neck with 25 IU of d-alpha-TOC, this amount being approximately equivalent to the amount poults would consume if their diet was supplemented with 150 IU of VE/kg during their 1st wk of life. Concentration, source, or route of VE administration did not affect growth parameters, plasma creatine kinase, plasma triglycerides, or liver lipid peroxidation as measured by the thiobarbituric acid reactive substances assay (TBARS). Plasma, red blood cells (RBC), and liver alpha-TOC decreased from hatching to 14 d of age in poults fed either source of VE. The use of 80 or 150 IU of dietary VE (either source) reduced (P < 0.05) the extent of depletion of alpha-TOC at all ages and also reduced the susceptibility of RBC to hemolysis. There was no effect of source of dietary VE on concentration of alpha-TOC in plasma, RBC, or liver, or on RBC hemolysis. Subcutaneous injection of 25 IU of d-alpha-TOC at Day 1 increased (P < 0.05) alpha-TOC concentration until 7 d of age. Also, d-alpha-TOC injection reduced (P < 0.05) RBC susceptibility to hemolysis through 21 d of age. Data showed that one single subcutaneous injection of 25 IU of d-alpha-TOC at 1 d of age was as effective as 80 IU or more of dietary VE through 21 d to improve the alpha-TOC status of poults.

Abstract
1. The effect of vitamin E (alpha-tocopheryl acetate) in turkey diets on the oxidative stability of raw and cooked turkey burgers and on the retention of alpha-tocopherol during refrigerated (4 degrees C) or frozen (-20 degrees C) storage was investigated. One hundred and two, one-day-old T-8s turkey poults were divided at random into 3 groups of 34 animals each and fed on either a basal diet (normal commercial turkey diet) supplemented with 20 mg alpha-tocopheryl acetate/kg (control) or fed an alpha-tocopherol supplemented diet containing 300 (E300) or 600 (E600) mg alpha-tocopheryl acetate/kg for 21 weeks. 2. Dietary supplementation with alpha-tocopheryl acetate significantly reduced TBARS numbers in both raw and cooked burgers during refrigerated and frozen storage. 3. The mean values of alpha-tocopherol in raw and cooked burgers stored at 4 degrees C did not change during storage. 4. In the case of both raw and cooked samples stored at -20 degrees C, the alpha-tocopherol values decreased from 5.67 to 3.54 and from 3.56 to 2.30 micrograms/g in the raw burgers from turkeys from the E600 and E300 treatments, respectively, after 4 months storage. The values decreased from 5.60 to 2.88 and from 3.29 to 1.85 micrograms/g in cooked burgers from turkeys from the E600 and E300 treatments, respectively, after 5 months storage.

Abstract
Over a period of 4 wk, 24 10-d-old broiler hens were fed diets containing 11% vegetable oil (9% rapeseed oil, 2% soybean oil), which was added either fresh (1 meq O2/kg oil) or oxidized (156 meq O2/kg oil). The effects of the dietary treatments on nutrient digestibility were examined in a balance experiment. The antioxidative status of the animals was evaluated using plasma concentrations of thiobarbituric acid-reactive substances (TBARS), erythrocyte hemolysis in vitro, selenium-dependent and selenium-independent activity of glutathione peroxidase in liver cell cytosolic fractions, and concentrations of tocopherols and other fat-soluble compounds with antioxidative properties (lutein, beta-carotene, and retinol) in plasma and various tissues (skeletal muscle, cardiac muscle, liver, and abdominal fat). Compared to the fresh oil, the concentrations of linoleic and linolenic acid were slightly lower in oxidized oil. The concentration of alpha-tocopherol in the diet with fresh oil was an average of 80.8 mg/kg diet, whereas the diet with oxidized oil only provided 44 mg/kg. The dietary selenium content averaged 0.48 mg/kg in both diets. During the experiment, none of the animals showed symptoms of diarrhea or vitamin E deficiency. The intake of oxidized oil caused a growth depression after 2 wk. The retention of fat (P = 0.07), energy (P = 0.09), and alpha-tocopherol (P < 0.01) was lower in the group fed oxidized fat. Furthermore, these animals showed significantly higher plasma concentrations of TBARS (P < 0.01), and lower concentrations of tocopherols, lutein, beta-carotene, and retinol in plasma and tissues.

Abstract
The effect of dietary oils [menhaden (MO), flax (FL), palm (PO), and sunflower oils (SF)] with added tocopherols on the tocopherol deposition, fatty acid composition, and thiobarbituric acid (TBA) values of egg or tissues (liver, adipose tissue, white meat, and dark meat) were examined. Addition of tocopherols increased (P < 0.05) the total egg or tissue tocopherol content. The enhancement of total tocopherols in the different tissues in the order of magnitude were egg yolk > liver > adipose tissue > dark meat > white meat. Dark meat contained higher (P < 0.05) total tocopherols than white meat. Dietary MO or FL resulted in a significant (P < 0.05) incorporation of C20:5 n-3 and c22:6 n-3 with a concomitant reduction in C20:4 n-6 in liver, egg, white meat and dark meat. Dietary SF resulted in a significant (P < 0.05) incorporation of C18:2 n-6 and C20:4 n-6 in all the tissues. Addition of PO did not result in any change in the yolk saturated fatty acid content. The content of monounsaturated fatty acids were greater (P < 0.05) in all the tissues from PO diets than in diets with other oils. Dietary tocopherols resulted in a significant increase (P < 0.05) in the content of C20:5 n-3 and C22:6 n-3 in the yolk, adipose tissue, and white meat from birds fed MO + T diets. Inclusion of tocopherols resulted in a significant (P < 0.05) reduction in TBA values in eggs, in liver for MO and FL diets, and in dark and white meat for the MO diet. Tocopherol supplementation did not result in any change in TBA values in the PO diet.

Abstract
1. Volatiles isolated from irradiated raw chicken were analysed by gas chromatography (GC) in conjunction with olfactory assessment of the effluent carrier gas to locate compounds with strong smells. 2. Sixteen odours of differing intensities were registered, some, but not others, coinciding with recognisable GC peaks. Identifications were made on the basis of retention data, mass spectrometric information and odour quality agreement. 3. Dimethyltrisulphide was found to be the most potent and obnoxious compound (foul gas, sulphurous), followed by cis-3- and trans-6-nonenals (soapy), oct-1-en-3-one (mushroom) and bis(methylthio-)methane (foul). With the exception of oct-1-en-3-one, none of these compounds has been reported before in irradiated raw chicken. 4. alpha-Tocopherol and ascorbic acid induce stability in tissues in vivo and post mortem. Chickens were reared on diets supplemented with high concentrations (800 mg/kg food) of each of these vitamins. Yields of irradiation volatiles from the tissues of these birds were very much reduced, compared to yields from similar tissues from birds fed unsupplemented diets. 5. Concomitantly with the reduced yield of volatiles, less odour was associated with the samples when analysed by GC-olfactory analysis. 6. The use of enhanced concentrations of the two vitamins in combination in the diet of poultry may provide a means of controlling development of off-odour in irradiated raw chicken, thus improving acceptability to the consumer.
