Research has been conducted to determine the effectiveness of antioxidant supplementation of vitamin E and C in the feed to meat quality of the Muscovy duck meat stored at room temperature, refrigerator and freezer.  Eighty-four Muscovy duck tail males aged 9 weeks maintained for 5 weeks and allocated into 7 treatments with 4 replications and each replication consisted of Muscovy duck 3 heads. Completely Randomized Design was applied, in the which treatments were vitamin E and vitamin C supplementation to the basal feed containing 21% protein and 3100 kcal / kg administered metabolic energy into seven groups namely E0C0: basal feed without Vit E and Vit C, E400: basal feed plus 400 IU of vitamin E, E600: basal feed plus 600 IU of vitamin E, C400: basal feed plus 400 mg / kg feed vitamin C, C600: basal feed plus 600 mg / kg feed as much vitamin C, E200C200: basal feed plus 200 IU vitamin E and 200 mg / kg feed vitamin C, and E300C300: basal feed plus 300 IU of vitamin E and 300 mg / kg feed of vitamin C. The parameters measured were the color of meat that includes the value of L * (lightness), a * (Redness) and b * (yellowness), tenderness and cooking looses.  The data obtained and the analysis of variance followed honestly significant difference test.Muscovy duck meat that vitamin E-supplemented feed brightness levels did not differ (P> 0.05) with non-supplemented,  otherwise Muscovy duck meat that feed supplemented vitamin C or a combination of vitamin E and C levels of brightness up to 3 days either at room temperature or stored the refrigerator is still high.  Supplementation of vitamin E and C was highly significant (P <0.01) against redness (a*) meat stored in different storage means. Muscovy duck meat that feed not supplemented vitamin E and C redness (a*) did not differ (P> 0.05) between the age of 0 hours with that stored in the refrigerator or freezer. B * value of Muscovy duck meat that feed not given vitamin E and C as well as different combinations (P <0.05) with Muscovy duck meat that feed supplemented with vitamin C or a combination of vitamins E and C. The Muscovy duck meat that feed supplemented vitamin E, C or a combination of vitamins E and C if stored at room temperature or refrigerator up to 3 days the value of L* and a* is still high, but the b * low.

The antioxidant effects of vitamins C and E on cryptorchidism-induced oxidative stress were investigated in male Sprague-Dawley rats. Forty rats (200–250 g) were randomly divided in a blinded fashion into five groups (). Group 1 was sham operated and treated with vehicle (corn-oil, 10 mL/kg). Groups 2, 3, 4, and 5 were rendered unilaterally cryptorchid and treated with vehicle (10 mL/kg), vitamin E solution (75 mg/kg), vitamin C solution (1.25 g/kg), and combination of vitamin E (75 mg/kg) and vitamin C (1.25 g/kg) solutions, respectively. Germ cell count, superoxide dismutase (SOD), total protein (TP), and testicular weight (TW) were lower, but malondialdhyde (MDA) was higher in the cryptorchid rats than the sham-operated rats. When administered separately, vitamins C and E increased germ cell count, SOD, TP, and TW but did not reduce MDA in the cryptorchid rats when compared to the vehicle-treated cryptorchid rats. However, there was no significant difference in these parameters between vehicle-treated and combined vitamins C- and E-treated rats. This suggests that vitamins E and C alleviate the germ cell loss and oxidative stress in cryptorchidism when administered separately but not when combined in rats.

The research was conducted to study the effect of heat stress on carcass characteristics and meat quality in indigenous sheep. Nine sheep were divided into three groups which were almost similar in age, sex and weight. Three groups were divided as zero hour (T0), four hours (T4) and eight hours (T8) heat exposure to direct sunlight. During experimental period temperature–humidity index (THI) value was calculated as 27.09 which indicated T4 and T8 groups were subjected to heat stress condition for at least four hours and eight hours respectively every day. Slaughter weight, body length and heart girth had no significant difference among the treatment groups. Dry matter, ash and ether extract had no significant difference (p>0.05) among the treatment groups but crude protein were increased with the increase of heat stress from T0 to T8 group (p<0.05). Drip loss was increased (p<0.05) in non-exposure group than treated groups but there is no significant result (p>0.05) found in pH and cooking loss. Carcass weight and eye muscle area had no significant difference (p>0.05) among the treatment groups but dressing percentage was decreased with the increase of time in heat treated groups (p<0.01). Significant difference (p<0.05) were found in weight of heart, kidney, lung + trachea and pluck between control and heat treated groups. The significant difference (p>0.05) in empty gut was found in gut with content and gut fill in heat treated groups. It can be concluded that heat stress had significant changes on carcass characteristics and meat quality of indigenous sheep.DOI: http://dx.doi.org/10.3329/bjas.v43i2.20717 Bang. J. Anim.

The present study was undertaken to find out the efficacy of vitamin E and/or vitamin C against mercury (Hg) induced toxicity in mice. Sixty mice were randomly divided into 5 equal groups (n=12). One group of mice (Group A) was kept as control and each of rest four groups (B, C, D and E) were fed with mercuric chloride (HgCl2) in drinking water @ 65 mg/L. In addition to HgCl2 alpha-tocopherol (vitamin E) @ 100 mg/L, ascorbic acid (vitamin C) @ 250 mg/L and combination of vitamin E and vitamin C at same dose were given to the mice of groups C, D and E respectively. All treatments were continued for 28 consecutive days. Four mice of each group were sacrificed on day 1, 14 and 28 and efficacy of vitamin E and vitamin C against Hg induced toxicity were evaluated by observing toxic signs, body weight, hemato-biochemical parameters and postmortem lesions. Mild (++) toxic signs as evident by reduced feed and water intake, salivation, vomiting, excitement, muscle tremor, ataxia, restlessness, incordination and ruffled hair coat were observed from 2nd week (group B) and from 3rd week (group C and D) by intoxication with HgCl2. Significant (P<0.01) reduction of body weight (18.38%) and hematological parameters i.e. TEC (19.88%), TLC (27.89%), Hb content (34.09%) and PCV (9.15%) were observed at day 28 in HgCl2 induced intoxicated mice (group B). At identical period in same group biochemical parameters i.e. AST (46.99%) and ALT (58.72%) increased significantly (p<0.01). Pinpoint hemorrhages throughout the liver and highly (++++) congested kidney was also observed at post mortem (group B). All the parameters i.e. toxic signs, body weight, hemato-biochemical and post mortem lesions were found to be slight (+) or mild (++) and/or improved in rest three groups of mice following treatment with vitamin E, vitamin C and combination of vitamin E and vitamin C. The present study reveals that vitamin E and C have a protective role against Hg poisoning. However, combination of vitamin E and C gave better results.DOI: http://dx.doi.org/10.3329/pa.v19i2.16949 Progress. Agric. 19(2): 93 - 100, 2008

SUMMARY Sedentary (sitting) time may produce many anatomical and physiological consequences which are supposedly associated with a decreased quality of life (QoL) related to foot health. Accordingly, this study aimed to analyze the QoL impact on the overall health and the foot health among male and female sedentary people. A total of 312 participants with an age mean of 39.81 ± 15.40 years completed all phases of the study. In addition, self-reported data were registered. The participants' sedentary lifestyle was determined using the European Prospective Investigation into Cancer and Nutrition (EPIC) physical activity questionnaire. Furthermore, the scores obtained from the Portuguese version of the Foot Health Status Questionnaire were registered. Sedentary people in the equivalent metabolic energy had 301.09 ± 72.22 (min/week). In the first section, values were higher for foot pain and foot function and lower for general foot health and footwear. In the second section, values were higher for general health and vigor and lower for physical activity and social capacity. The differences between the sex groups of the study were statistically significant for footwear (P = 0.008), physical activity (P= 0.002), social capacity (P = 0.001) and vigor (P = 0.001) showing a worst QoL related to foot health in favor of male subjects in comparison with females. The rest of the domains did not show any statistically significant difference (P ≥ .01). The sedentary population evidenced a negative impact on the QoL related to foot health. This problem may be associated with this lifestyle, especially for males.

ObjectivesThe objective was to evaluate the effect of supplementing α- and γ-tocopherol vitamin E isoforms with corn oil and tallow on carcass characteristics and meat quality of pigs grown to heavier weights (>150 kg).Materials and MethodsIndividually fed pigs (n = 72; 36 barrows, 36 gilts; 28.55 ± 1.16 kg) were randomly assigned to 12 dietary treatments in a 2 × 6 factorial arrangement. Fat treatments were tallow and corn oil (5?). The vitamin E treatments included four levels of α-tocopheryl-acetate (ATA; 11, 40, 100, and 200 ppm) and two levels of mixed tocopherols (primarily γ-tocopherol; 40 and 100 ppm). Pigs were humanely slaughtered at approximately 150 kg. 45 min pH was taken at the 10th rib. After 24 h chill (4°C), carcass measurements were taken (carcass length, backfat depth at first rib, last rib, 10th rib and last lumbar, loin muscle area, and 24 h pH at the 10th rib). In addition, wholesale weights from the Boston butt (IMPS #406), shoulder picnic (IMPS #405), loin (IMPS #412), and belly (IMPS #408) and spareribs were recorded. Furthermore, bellies were divided into eight sections and the average depth was taken at each section and the vertical and lateral belly flex was measured. Drip loss was determined by suspending a 1.3cm chop at 4°C for 48 h and purge loss was determined from approximately 2kg vacuum packaged loin muscle sections at 0, 7, 14, and 30d. Objective (Hunter Lab Colorimeter XE Plus) and subjective (NPPC color, marbling and firmness scores) measurements were taken at the 10th rib. Data analysis were performed in SAS by least squares analysis of variance using the generalized linear model as a randomized complete block design. The individual pig served as the experimental unit and results were reported as least square means.ResultsThere were no differences in dressing percentage, 24 h pH, backfat depth, loin muscle area, primal cuts, purge loss, and drip loss between the two vitamin E isoforms. Fat treatments did not affect dressing percentage, 45 min and 24 h pH, backfat depth, loin muscle area, primal cuts, purge loss, drip loss as well as objective and subjective color. Although not significant (P = 0.07), pork from the γ-tocopherol pigs had a lower pH than the ATA treatment. The γ-tocopherol supplementation tended to have a lighter subjective color (P = 0.06) as well as increased L*, decreased a*, and increased the hue angle calculations at 7d shelf-life. The belly depth was greater (P = 0.01) along with higher lateral (P < 0.01) and a lower vertical (P < 0.01) flex for pigs fed tallow.ConclusionIn conclusion, feeding tallow to heavy weight pigs (150 kg) could improve belly firmness. Also, α-tocopherol did not improve shelf-life stability and γ-tocopherol could negatively affect subject and objective pork loin color.

This study aims to determine the concentration of starfruit juice and dragon fruit peel on the quality of jam. The experimental design used was a one-factor Randomized Block Design (RAK) with six treatments and three replications to obtain 18 samples. The treatments were the concentration of starfruit juice and dragon fruit peel extract with P1 (100% : 0%), P2 (85% : 15%), P3 (70% : 15%), P4 (55% : 45%), P5 ( 40% : 60%) and P6 (25% : 75%). Parameters observed were vitamin C levels, antioxidant activity, spread, and color as well as sensory tests (color, aroma, and taste). Data analysis results were tested by analysis of variance at a significance level of 5% using Co-Stat software. If there is a significant difference, then the orthogonal polynomial further test is carried out, while the physical and sensory tests are further tested using the Honest Significant Difference test at a significance level of 5%. The results showed that the concentration of star fruit juice and dragon fruit pulp did not have a different effect on vitamin C levels but had a significantly different effect on antioxidant activity, spread, and color. P6 treatment resulted in the highest antioxidant activity of 77.27%, 12.80 mg of vitamin C content, 10.1 cm of smearing power, and sensory properties that were acceptable to the panelists.

Our aim was to analyse the influence of variegate porphyria (VP) on the antioxidant defenses and markers of oxidative damage and inflammation in plasma and neutrophils and the effects of dietary supplementation with vitamins E and C on these parameters in plasma, neutrophils and erythrocytes. Twelve women affected by VP and twelve pair-matched healthy control women participated in a double-blind crossover study. Each participant took 50 mg/d of vitamin E and 150 mg/d of vitamin C, or a placebo, for 6 months, by consuming an almond-based beverage as the vehicle. Women affected by VP presented higher C-reactive protein and malondialdehyde (MDA) circulating levels. Plasma antioxidant defenses were not different between porphyric and control women. Neutrophils from VP women presented decreased catalase (CAT) and glutathione reductase (GR) activities together with increased protein carbonyl levels. Reactive oxygen species (ROS) production from stimulated neutrophils was also higher in porphyric women than their controls. Dietary supplementation was effective in increasing α-tocopherol levels in neutrophils and in reducing MDA levels in plasma. Erythrocyte CAT and GR activities were enhanced by the enriched beverage only in the control subjects. In conclusion, women affected by VP present a situation of inflammation, plasma oxidative damage and neutrophils more primed to the oxidative burst, with decreased antioxidant activities and increased ROS production capabilities and protein oxidative damage. Dietary supplementation with vitamin E (50 mg/d) and vitamin C (150 mg/d) for 6 months decreased plasma oxidative damage and enhanced the erythrocyte activities of CAT and GR.
