This experiment was carried out to investigate the effects of dietary vitamin C and E on carcass characteristics of Hanwoo steers. Thirty seven Hanwoo steers were randomly assigned to one of four treatments. The four treatments were control(vitamin E 20 IU/kg feed), vitamin C(vitamin C 0.1%/kg feed and vitamin E 20 IU/kg feed), vitamin E(vitamin E 220 IU/kg feed) and vitamin C plus E(vitamin C 0.1%/kg feed and vitamin E 220 IU/kg feed). Hanwoo steers were fed experimental diets for 3 months of the last finishing period. Animals fed the diet containing vitamin C plus E had higher(P<0.05) yield grade than those fed the other diets but quality grade was not different between animals fed the control diet and vitamin-supplemented diets. Proximate analysis in longissimus dorsi was not different between animals fed the control diet and vitamin-supplemented diets. Vitamin C concentration in longissimus dorsi was higher (P<0.05) in the animals fed the vitamin C diet and the vitamin C plus E diet than in those fed the control diet and the vitamin E diet. Vitamin E concentration in longissimus dorsi was higher(P<0.05) in the animals fed the diet supplemented with vitamin E and the diet supplemented with vitamin C plus E than in those fed the control diet and the vitamin C diet. Animals fed the diet supplemented with vitamin C was higher(P<0.05) in myristic acid, palmitic acid, palmitoleic acid and oleic acid in the longissimus dorsi than those fed the other diets, but linoleic acid in longissimus dorsi was higher(P<0.05) in the animals fed the vitamin E diet than those fed the other diets. However, saturated fatty acid and unsaturated fatty acid were not different between animals fed the control diet and vitamin-supplemented diets.

Heat stress환경의 육용종계에서 사료에 첨가한 비타민 C(200 mg/kg)와 비타민 E(250 mg/kg)가 난각 품질 및 경골 강도에 미치는 영향을 확인하고자 실험을 실시하였다. 강제 환우에서 회복된 83주령의 Ross품종 육용종계 160수를 4처리 4반복 10수씩 개별 케이지에 수용 한 뒤, 10일간의 적응 기간을 둔 뒤, 3주간에 걸쳐 32$^{\circ}C$에서 지속적으로 온도를 유지하면서 사료 섭취량, 산란율, 폐사율, 난중, Haugh unit, 난각의 품질, 경골 파괴강도 그리고 혈액 중의 혈구 세포 등을 조사하였다. Heat stress는 폐사율, 산란율, 난중, 그리고 Haugh unit를 감소시키는 경향이 있었으나 통계적으로 유의하지는 않았다. 난각의 SWUSA와 압축 파괴강도는 비타민 C/E 첨가구에서 2, 3주차에 무첨가구보다 유의하게 높았으나 (P<0.05), 비타 C 또는 E 첨가구 사이에서는 유의차가 없었다. Heterophil과 lymphocyte의 숫자는 heat stress 동안에 각각 증가 또는 감소하였다. 처리구간에는 비타민 C/E 첨가구가 H/L/ratio 수준이 가장 낮았으며, 무첨가구가 가장 높은 경향을 나타내었다. 경골의 파괴강도는 비타민 C 첨가구에서 가장 높았다(P<0.05). 혈액 중의 비타민 C 농도는 비타민 C첨가구와 비타민 C/E 첨가구에서 각각 12.73 g/ml과 8.23 g/ml으로 높았다(P<0.05). 비타민 E 첨가구와 비타민 C/E 첨가구에서 혈액 중 비타민 E 농도가 유의하게 높았다 (P<0.05). Corticosterone 농도는 무첨가구에서 5.97g/ml으로 통계적으로 유의하게 높았다.(P<0.05).

The effects of high levels of vitamin E and cholesterol feeding on the lipid composition of the plasma lipoproteins were tested between 4 experimental groups. The concentrations of vitamin E and cholesterol in the plasma lipoproteins were significantly increased with the feedings. But the concentrations of cholesterol and various lipid fractions showed significant low levels on the vitamin E feeding group, which vitamin E was fed after the cholesterol diet. Vitamin E showed the hypocholesterolemic effect when it was fed after the high cholesterol containing diet. But, vitamin E was less effective to decrease the content of cholesterol on the diet which contained the both vitamin E and 2% cholesterol. It also showed that vitamin E could stimulate the absorption of cholesterol and lipid when the both dietary factors were simultaneously fed. The vitamin E feeding also resulted in increase of the cholesterol concentration in HDL/LDL ratios.

This experiment was earned out to investigate the effects of dietary vitamin C and E on lipid oxidation and stability of color in Hanwoo steer beef. Thirty seven Hanwoo steers were randomly assigned to one of four treatments. The four treatments were control(vitamin E 20IU/kg feed), vitamin C(vitamin C 0.l%/kg feed and vitamin E 20IU/kg feed), vitamin E(vitamin E 220IU/kg feed) and vitamin C plus E(vitamin C 0.l%/kg feed and vitamin E 20IU/kg feed). Hanwoo steers were fed the experimental diets for 3 months at the last finishing period and pH, color, TBARS, concentration of myoglobin, water holding capacity, reduction by heat, drip loss and purge loss of longissimus dorsi were analyzed at 1, 3, 5, 7 and 10th day of storage, respectively. pH value, Hue angle, metmyoglobin concentration, TBARS, drip loss and purge loss in longissimus dorsi were increased as the storage period elapsed. However, water holding capacity in longissimus dorsi was decreased as the storage period elapsed. The animals fed the vitamin C plus E diet were higher in pH value and oxymyoglobin concentration, and lower in metmyoglobin concentration than in those fed the other diets during the whole storage period and lowest in TBARS. TBARS and Hue angle in longissimus dorsi were 10wer(P<0.05) in the animals fed the vitamin-supplemented diets than in those fed the control diet. Reduction by heat in longissimus dorsi was higher(P<0.05) in the animals fed the diets supplemented with vitamin E or vitamin C plus E than in those fed the control diet or vitamin C-supplemented diet. According to these results, it may be concluded that feeding the diets containing 0.1% vitamin C or 220IU vitamin E per kg feed or the diet mixed 0.1% vitamin C with 220IU vitamin E to Hanwoo steers can retard lipid oxidation of longissimus dorsi and stabilize beef color.

This experiment was carried out to investigate the effects of dietary vitamin E levels on carcass characteristics and vitamin E contents, fatty acid composition and lipid oxidation as indicated by thiobarbituric acid reactive substances(TBARS) of the longissimus muscle in Hanwoo steers. Forty Hanwoo steers were randomly assigned to one of four groups and fed the diet containing 200(control), 1000, 2000 or 2500 IU a(alpha)-tocopherol acetate/head/day for 3 months of last finishing period. Backfat thickness was thinner and beef fat color was whiter(P<0.05) in steers fed the vitamin E supplemented diets than those fed the control diet. But the longissimus muscle area and yield grade did not differ among treatments. Marbling score and quality grade were higher(P<0.05) in steers fed the diets containing 1000 and 2000 IU vitamin E than those fed the other diets. Vitamin E concentration in the longissimus muscle was higher(P<0.05) as the vitamin E content in diet was higher. The levels of oleic and linoleic acids in the longissimus muscle were not affected by dietary vitamin E levels. But linolenic and arachidonic acids were lower in steers fed the vitamin E supplemented diets than those fed the control diet. TBARS in the longissimus muscle was not affected by the vitamin E levels in diet until 5th day of storage but delayed muscle lipid oxidation in steers fed the vitamin E supplemented diets after 7th day of storage. Therefore according to this result, it may be concluded that steers have a higher quality grade and higher vitamin E concentration in muscle and lower in TBARS when diet contains 1000 or 2000 IU vitamin E per kg of diet.

This study was carried out to examine the effects of vitamin E on chronic gastric ulcer induced by alcohol treatment in rats. Chronic gastric ulcer model was established by oral administration of 70% ethanol at one time and supply of 15% ethanol for additional 7 days. Male Sprague-Dawley rats, approximately 200 g, were fasted for 24 hours and orally gavaged with 1 mL of 70% ethanol for the induction of acute ulcer. A supply of 15% ethanol dissolved in distilled water for 7 days were followed to maintain chronic gastric ulcer. Acute ulcer group was sacrificed at 3 hours after oral administration of 1 mL of 70% ethanol. Chronic groups were divided into three groups according to vitamin E levels; low-vitamin E (LVE, 0 mg/mL oil/day), normalvitamin E (NVE, 1 mg/mL oil/day) and high-vitamin E (HVE, 10 mg/mL oil/day). These groups were fed vitamin E free diets which were made of vitamin E free vitamin mix followed AIN-93M pattern for 7 days. Histological findings of congestion, hemorrhage and necrosis in gastric tissue were shown severely in acute ulcer group and LVE group of chronic ulcer groups. The concentration of gastrin in serum was significantly higher in LVE group. The content of histamine in stomach was lower in acute ulcer group but there was no significant difference among the chronic groups regardless of vitamin E levels. Content of malondialdehyde (MDA) in gastric tissue was higher in HVE group and activities of antioxidant enzyme, glutathione peroxidase (GPx) and catalase, were lower in HVE group. Myeloperoxidase (MPO) activities as a marker of neutrophils infiltration was significantly higher in LVE group. These results suggested that vitamin E supplementation has positive effects on healing of alcohol-induced chronic gastric ulcer through alleviation of gastric tissue injuries and reduction of the MPO activity in gastric tissue and gastrin in serum.
