Three oat cultivars and one oat breeding line were evaluated for chemical, hydration and pasting properties. Protein, starch and β-glucan levels ranged 11.13∼14.37, 56.37∼64.86 and 3.44∼4.76%, respectively. The oat cultivars Daeyang and Seonyang contained higher β-glucan levels of 4.76 and 4.35%. The Daeyang variety had a higher water absorption index (WAI) of 2.83∼3.35 (g/g), but a lower water solubility index (WSI) of 8.67 ∼11.08%. Daeyang and Seonyang cultivars showed higher peak and trough viscosity, but lower breakdown and setback, indicating that they easily swell, and thus could possibly provide the desirable viscosity of an oat product. The β-glucan levels were correlated positively with WAI, peak and trough viscosity, and negatively to WSI, breakdown and setback viscosity.

, compared with 14.1 ton ha -1 of check cultivar. Cultivar 'Okhan' was lower than the check cultivar 'Samhan' in terms of the protein content (9.2% and 9.9%, respectively) and total digestible nutrients (58.5%, and 59.3%, respectively), while the TDN yield per ha was more than the check (8.70 and 8.36 kg, respectively). Fall sowing cropping of 'Okhan' is recommended only in areas where average daily minimum mean temperatures in January are higher than -7°C, and it should not be cultivated in mountain areas, where frost damage is likely to occur.

This study was conducted to investigate effects of different levels of seleniferous whole crop barley (WCB) supplementation on performance, and blood characteristics as physiological responses in growing pigs. A total of 20 cross-bred pigs ((Landrace × Yorkshire) × Duroc) were divided into 4 treatments of 5 pigs each and experimental period lasted for 6 weeks. They were fed diets containing 0.1 (non-seleniferous WCB as controls), 0.2, 0.4, and 0.6 mg/kg levels of selenium (Se) by supplementing seleniferous WCB, and non-seleniferous or seleniferous WCB was formulated to 5% level in total ration. The diets were isonitrogenous (18% crude protein) and isocaloric (3,500 kcal/kg digestible energy) across treatments.Increasing levels of seleniferous WCB supplements did not affect feed intake and BW gain, and blood total protein concentration was (p<0.05) significantly higher for 0.2 mg/kg Se treatments than for controls. On d 14, blood albumin concentration was higher (p<0.05) for seleniferous WCB supplemented groups than for control group. Contrarily, blood glucose concentration was tended to be higher for controls than for seleniferous WCB groups. Blood total lipid concentration was significantly (p<0.05) lowered with increasing levels of seleniferous WCB. Serum glutamic-oxaloacetic transaminase and glutamic-pyruvic transaminase did not have any difference among treatments. It was tended that blood total cholesterol and triglyceride were lowered with increasing levels of seleniferous WCB. Blood Se concentration was significantly (p<0.05) increased with increasing levels of seleniferous WCB. The results indicate that Se present in seleniferous WCB had favorable effects on blood characteristics and blood Se increased by supplementing seleniferous WCB implies not only a good intestinal absorption of Se present in WCB but also the possibility of Se transfer into tissues.
