The yield performance and nutrient quality of barley for pellets making from whole crop material were discussed during 1993-1994. Barley (cv. Olbori) was grown on paddy land after rice cutivation and was harvested at early stage of physiological maturity. A column type of whole crop pellets was produced by 1.5cm diameter and 2.5cm height. Barley war evaluated as a suitable materials for whole crop pellet making. Barley produced higher yield and better qualitative roughage in the utilization of pellet making than in the silage making. Dry matter yields were obtained 12.02 MTha in pellet making and 11.70 MT/ha in silage making. Net energy value of barley pellet were 6.54 MJ in net energy lactation and 635 SV in starch equivalent net energy. Feeding of barley pellet improved milk production of daily cattle Daily milk yields per head were 25.1 liter in silage feeding and 25.9 liter in pellet feeding. Production cost of pellets and silages made from whole crop barley were 169.07 won/kg and 124.15 won/kg dry matter, respectively.

This study was conducted to observe the fermentative quality and anthocyanin content in whole crop colored barley silage during storage periods and anthocyanin stability in in vitro ruminal fluid. Silages of colored barley cultivar "Boanchalbori" and normal barley cultivar "Yuyeonbori" were stored during 0, 2, 4, 6, and 12 months. The in vitro ruminal fluid was fermented for 0, 6, 12, 24, and 48 hrs. For the feed value, crude protein of colored barley silage was slightly increased in the silage compared to that of normal barley silage, and being increased up to 2 months after ensiling and thereafter maintained at the similar level. Neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents of both the barley significantly increased by prolonged storage of 2 months (p<0.05), but they were maintained at the constant level after 2 months of storing silage. Whereas TDN (total digestible nutrients) contents of them were decreased by the prolonged storage of 2 months (p<0.05), then maintained at the constant levels. The fermentative quality and pH values in both the barley silages were slightly decreased during the storage time. Lactic acid and acetic acid contents were increased during prolonged storage period, but not significantly different among treatments. Butyric acid was not detected. In the colored barley silage, pH value showed slightly lower compared to that of the normal barley silage but not significant, and lactic acid content was significantly higher than the normal barley silage (p<0.05). The total anthocyanin content in the whole crop colored barley silage decreased to 42% after 2 months of ensilage, however maintained at the constant level until 12 months of ensilage. In the case of anthocyanin stability on in vitro ruminal fluid digestion, the pH value of the ruminal fluid was slightly lower at 6, 12, 24, 48h incubation time and the content of anthocyanin was at similar levels. These results indicated that the colored barley showed higher fermentation quality, and total anthocyanin content was maintained stable at 42% level of the first value in storing silage. As the anthocyanin had higher stability in the ruminal fluid, the colored barley has a potential as functional feeds for Ruminants.

This study investigated the effects of drying methods and drying time on the changes in anthocyanin content in colored barley. Colored barley cultivar Boanchalbori was harvested at a time when the anthocyanin content was the most and dried in afield. The harvested barley was then treated by two methods, sun drying and shade drying, for 4, 8, 24, and 32 h. The moisture content of the sun-dried barley decreased slightly faster than shade-dried samples, but the difference was not statistically significant. Chemical analysis indicated that the samples dried under shaded conditions had slightly higher crude fiber and lower nitrogen free extract, but the difference was not statistically significant. There was no difference in the total digestible nutrients between the two methods. In the case of sun-dried barley, the anthocyanin content decreased compared to the control and shade-dried samples after drying for 4 h (p < 0.05), was maintained at a constant level at 24 h, and then decreased at 32 h. In case of shade-dried barley, the anthocyanin content decreased gradually with the drying time, and a significant decrease was found at 24 h of drying (p<0.05) as compared to the control. The shade-dried method was more successful in reducing anthocyanin loss than the sun-dried method (p<0.05). There was a slight decrease in 1,1-Diphenyl-2-Picrylhydrazyl radical scavenging with drying time in the shade-dried method, and a significant decrease after 4 h with the sun-dried method. These results showed that covering with a two-layer awning was advantageous to dry colored barley in the field conditions.

Mechanical transmission of barley seedlings with barley yellow mosaic virus (BaYMV) is generally inefficient and is the major constraint for testing cultivar resistance to the virus. To explore mechanical transmission, BaYMV-infected barley plants were grown at different conditions and used as inoculum sources to seedlings of susceptible barley cultivar Baegdong. Extracts prepared from BaYMV-infected Baegdong plants at 47, 53, 74, and 90 days after symptom appearance (DASA) and grown at 10 and $12^{\circ}C$ gave 10, 30, 68 and 76% infection, respectively on inoculated susceptible barley cv. Baegdong seedlings. While Jinyangbori, another susceptible cultivar obtained 95% infection rate inoculated with extracts from 90 DASA disease source and grown at $10/12^{\circ}C$. However, low infection rates were obtained when the virus sources were grown in a greenhouse at $15-18^{\circ}C$. Our results indicate that longer incubation period and lower temperature are required for virus accumulation and stability.

농촌인력 감소와 지구 이상기상 증가에 따라 콩 재배 시 생력적인 잡초방제 및 토양유실억제 기술이 요구된다. 콩과 동시에 파종한 활물피복용 보리의 잡초발생 및 경사지 토양유실의 억제 효과가 2013, 2014년 2년간 수원 시험포장에서 조사되었다. 활물피복 보리의 지상부 피복량은 파종 후 40일에 200~300 kg/10a, 파종후 60일에 100~200 kg/10a의 건물중을 얻을 수 있었으며 이에 따라 콩의 초기 생육상태에서 잡초발생이 현저히 줄어들었다. 잡초발생량에서 보리 활물피복은 토양처리제와 같은 억제효과를 나타내었다. 콩 식물체 초기생육량은 활물피복 보리와의 경합으로 인해 많이 감소하였는데 활물피복 보리가 하고 됨에 따라 콩의 후기생육은 많이 회복되어 수확기에서는 무피복구의 70~80%를 나타내었다. 콩 종실 수량은 2013년에 무피복구가 생육이 과번무하여 활물피복구보다 감소하였다. 그러나 2014년에 무피복구에서 적심 처리하였을 때 종실수량이 증가하였는데 보리활물피복구와 수량의 차이가 없었다. 따라서 활물피복 재배도 관행재배(무피복)와 비슷한 수량성을 확보하는 것이 가능하였다. 경사지의 토양유실 시험에서는 보리 활물피복에 의해 유거수량이 약 20~50%, 토양유실량이 약 70~90% 감소하여 토양유실 억제효과가 컸다. 2014년 비닐+보리활물피복도 토양유실억제 효과는 보리활물피복구와 같았다. 콩과 동시에 파종한 보리의 활물피복 이용은 종실수량의 큰 감소 없이 생력적으로 잡초를 관리할 수 있고 경사지의 토양을 보전하는 효과가 커서 앞으로 유망 시 되는 기술이라고 할 수 있다.

Barley's nutritional value as a health food is increasing due to its excellent nutritional functionality. In this study, the levels of β-glucan, total polyphenols, and total flavonoids were analyzed in the ethanol extracts of different barley cultivars (Hinchalssal, Heuksoojeongchal, Betaone, Ganghochung, and Saechalssal). Also, the free radical scavenging abilities of 2,2-diphenyl-1-picryl-hydrazil (DPPH) and 2,2'-azino-bis-3-ethylbenzo-thiaxoline-6-sulfonic acid (ABTS) were measured to determine their antioxidant activity. The results confirmed that Betaone extract contained highly activefunctional components and exhibitedantioxidant activity. Next, we evaluated the hepatoprotective and inhibitory effects of reactive oxygen species (ROS) generated by barley ethanol extracts after inducing oxidative stress with tert-butyl hydroperoxide (tBHP) in HepG2 cells. Hinchalssal and Saechalssal extracts showed the most significant cytoprotective effect and also reduced ROS production significantly. These results suggest that Hinchalssal, Saechalssal, and Betaone represent potential natural antioxidant and hepatoprotective agents.

The purpose of this study was to determine the effect of different feeding ratios of whole crop barley silage on the embryo production in Hanwoo donors. All donors were basically fed 2.5 kg concentrate daily. Donors were divided into three groups according to the different feeding of forage; hay 70% and rice straw 30% (control, n = 21), whole crop barley silage 80% and rice straw 20% (T1, n = 25), and whole crop barley silage 60% and rice straw 40% (T2, n = 23) fed based on TDN 6.70/ BW 500 kg. All Hanwoo donors received a CIDR together with injections of 1 mg estradiol benzoate and 50 mg progesterone ($P_4$, Day 0). Four days later, they were superovulated with 28 mg FSH twice daily IM in decreasing doses over 4 days. Then donors received 2 doses of $PGF_2{\alpha}$ (25 and 15 mg) with the 5th and 6th injections of FSH on Day 6. CIDR were withdrawn at the 6th FSH injection and the donors received $100\;{\mu}g$ GnRH 36 h after the second $PGF_2{\alpha}$ injection. The donors were artificially inseminated twice, at 8 and 24 h after GnRH, and embryos were recovered 7 or 8 days after the 1st insemination. The flush rate of the donors following positive superovulation responses did not differ among groups (76.2~96.0%, p>0.05). The number of corpus luteum (CL) at embryo recovery also did not differ among groups (10.6~14.0, p>0.05). Furthermore, the mean numbers of total ova (9.4, 10.5 and 12.0) and transferable embryos (5.3, 12.0 and 6.5) did not significantly differ among the control, T1 and T2 groups, respectively (p>0.05). However, mean concentrations of serum $P_4$ of the T1 (64.2 ng/ml) and T2 groups (55.7 ng/ml) were higher than that of control group (43.3 ng/ml, p<0.01), while serum cholesterol concentrations in the control (105.8 mg/dl) and T2 groups ($96.9\;{\pm}\;mg/dl$) were significantly lower than in the T1 group (121.1 mg/dl, p<0.05). Conclusively, whole crop barley silage can be fed a good substitute for hay forage for Hanwoo donors. Furthermore the ratios of whole crop barley silage 60% and rice straw 40% might be more worthful for embryo production.
