  • Feedlot and in vitro ruminal experiments were conducted to assess the effects of saponin-containing surfactant applied during tempering of barley grain on cattle growth performance and on ruminal fermentation. In the feedlot experiment, treatments with three barley grain/barley silage based diets were prepared using barley grain at 7.7% moisture (dry, D), after tempering to 18% moisture (M), or after tempering with a saponin-based surfactant included at 60 ml/t (MS). Each treatment was rolled at settings determined previously to yield optimally processed barley. A total of 180 newly weaned British${\times}$Charolais steers were fed three diets in 18 pens for a 63-d backgrounding period and 91-d finishing period to determine feed intake, growth rate and feed efficiency. Cattle were slaughtered at the end of the experiment to measure the carcass characteristics. Tempering reduced (p<0.001) volume weight and processing index, but processing characteristics were similar between MS and M. Tempering increased (p<0.05) growth during backgrounding only, compared with D, but did not affect feed intake in either phase. During backgrounding, feed efficiency was improved with tempering, but during finishing and overall this response was only observed with the surfactant. Tempering did not affect carcass weight, fat content or meat yield. Surfactant doubled the proportion of carcasses grading AAA. In the in vitro experiment, barley (500 mg; ground to <1.0 mm or steam-rolled) was incubated in buffered ruminal fluid (40 ml) without or with surfactant up to 20 ${\mu}l/g$ DM substrate for 24 h. Surfactant increased (p<0.05) apparent DM disappearance and starch digestibility but reduced productions of gas and the volatile fatty acid and acetate:propionate ratio, irrespective of barley particle size. Compared with feeding diets prepared with non-tempered barley, tempering with surfactant increased the feed efficiency of feedlot steers. This may have arisen from alteration in processing characteristics of barley grain by surfactant rather than its direct effect on rumen microbial fermentation.

  • We examined the adaptability of Korean winter forage crops such as Italian ryegrass, barley, oat, and triticale in Uzbekistan. The overall growth before wintering was slightly different between Uzbekistani and Korean varieties, but there was no significant difference among winter forage crops. The heading date of the Korean triticale 'Shinyoung' was the earliest, (April 4), and the heading date of the Uzbekistani triticale 'Frack cerebristy' was quite late, (April 25). The heading date of the Korean Italian ryegrass 'Kowinearly' was four days earlier than that of 'Kowinmaster,' on April 13, and that of the Korean barley 'Youngyang' and 'Yuyeon' were five days earlier than that of the Uzbekistani barley 'Bolgaly'. The maximum dry matter yield of winter forage crop was from Uzbekistan triticale, 'Frack cerebristy', which was 13,536 kg/ha. The dry matter yield of Uzbekistan barley was 8,222 kg/ha. Compared with Uzbekistan barley, 'Bolgaly', yields of Korean barley 'Youngyang' and 'Yuyeon', Korean oat 'Samhan', and Korean Italian ryegrass 'Kowinearly' and 'Kowinmaster' were 59~64%, 125%, and 113~133%, respectively.

  • Quality characteristics of yogurt with added colored barely flour was investigated during fermentation by lactic acid bacteria. Chemical properties such as moisture, crude protein, starch, ash and ${\beta}$-glucan contents was measured. pH, acidity, brix, Hunter color value and growth of lactic acid bacteria in yogurt was investigated during fermentation by L. acidophilus, L. bulgaricus, and S. thermophilus mixed culture. Crude protein contents of Daeanchal and Boseokchal was 16.16 and 12.17%, respectively. Starch contents of daeanchal were shown lower score. The pH of yogurt by addition of barley flour (Daeanchal) addition 0 and 20% were 6.66 and 6.40, respectively. The pH of yogurt supplemented with barley flour tended to be lower than before control which was not added barely flours and oligosaccharide in yogurt. Titratable acidity of yogurt added barley flour was higher compared with that of control. Brix of yogurt was decreased during fermentation by lactic acid bacteria. Lightness of yogurt added barley flour (Daeanchal) addition 0 and 20% were 83.25 and 69.83, respectively. The original microbial population of the yogurt during 0, 5, 8, and 15 hr fermentation were 7.48, 7.79, 8.15, and 8.71 Log CFU/g, respectively. Moreover, the addition of colored barley flour was to promote the proliferation of lactic acid bacteria in yogurt. In our research, addition of colored barley flours added into the yogurt may also have contributed to growth of lactic acid bacteria.

  • A total of 16 growing pigs (Landrace${\times}$Yorkshire${\times}$Duroc, average weight $71{\pm}2kg$) were used in this experiment for 24 days to determine the effect of replacing ground corn with barley varieties on growth performance, nutrient digestibility, and blood metabolites. Each pig was housed individually in a metabolic cage with a nipple waterer and feeder. Four dietary treatments included control (a corn and soybean meal-based diet) and 3 barley varieties (Youngyang, Wooho, or Yuyeon barley replacing 40% of ground corn). Growth performance and nutrient digestibility were not affected by replacement of 40% of ground corn with one of the three barley varieties (p > 0.05), but final body weight was. As for blood characteristics, pig treated with all of the barley treatments had no effect (p > 0.05) on total protein, albumin, aspartate aminotransferase (AST), alanine aminotransferase (ALT), lactate dehydrogenase (LD), and glucose in comparison with control; however, there was a difference in high density lipoprotein (HDL)-cholesterol levels between the control and all of the barley replaced treatment groups (p < 0.05). In conclusion, in spite of statistically significant differences, each of the three barley varieties is a suitable substitute for ground corn in the diet of growing and fattening pigs without adverse effects on growth performance, nutrient digestibility, and blood characteristics.

  • Yield loss of wheat and barley due to meteorological constraints has been analyzed in order to get the basic information, which will lead to the counter-measures for dissemination of agricultural technology and administration. These meteorological damages were analyzed on the results of percentage yield loss and mechanism of damage and the aspects of constraints were explained. The annual yield loss of wheat and barley were 21.7% by meteorological stress: Cold damage, 5.9% ; excessive soil moisture, 5.6% ; lodging, 2.9% ; drought, 3.0% ; disease, 4.3% etc. Those damages by the stresses mentioned above and rain damage were analyzed in relation to the growth stages and the degrees of damage. The predispositions and the growth of wheat and barley to those meteorological stress are also discussed. Varietal resistances of wheat and barley to those stresses were indexed and the physiological and morphological characteristics of these resistant cultivars are described. Cultural practices to minimize the damages were also reviewed.

  • Research on barley as an animal feed started some decades ago but its utilization in animal production has been limited to countries that grow the crop extensively. Corn has been the most popular energy feed in cattle rations, but the high price of corn and the decreased supply of the grain in the international market have shifted the focus of the animal industry to other cereal crops like barley. Studies have indicated that growth performance of cattle fed barley-based diets has been generally comparable with that of those fed corn-based diets, while results for cattle fed whole-crop barley silage have been more variable. Beef from cattle fed barley-based diets has proved to be as tender and as acceptable for taste as that from animals fed other finishing diets when compared at similar growth rates and degree of finish. The barley crop contains good amounts of antioxidants like 2"O-GIV isovitexin, so from the meat science point of view, a desirable influence of these components on meat quality traits such as meat color, oxidative stability and sensory characteristics might be expected. Furthermore, the effect of the distinctive fatty acid profile of beef fed from whole-crop barley silage on sensory traits is also an important subject to be elucidated. A lot of studies have been made over past decades on the effect of barley, and especially whole crop barley, on beef cattle production and meat quality, but these data have not been collectively documented in a review. The current review re-visits previous literature to underline the effects of barley in the diet on beef quality traits and to identify areas for further studies.

  • Spawn is the vegetative growth of the mycelium and serves as the inoculum or seed for cultivating mushrooms. Various cereal grains, such as wheat, millet, barley, sorghum, brown rice, rye, and oat were assessed to compare their characteristics and suitability for spawn production of button mushroom (Agaricus bisporus). The mycelial growth rates, density, and the number of completely colonized grains were measured from the twentieth day of inoculation. Wheat grains showed fastest mycelial growth with 8.4 cm followed by rye, oat, barley with 8.2, 7.5 and 7.3 cm, respectively. In the mycelial density, foxtail millet, barley, and sorghum were best compared with that of wheat grains. Especially, the number of grains which were completely colonized by mycelia were greatest in foxtail millet with 5,123 grains followed by proso millet, and wheat with 3,052 and 914, respectively. Based on the results obtained, barley, foxtail millet, and sorghum grains would be appropriate substituting for wheat grain in spawn production of button mushroom.
