Objective: The objective of this study was to compare the feeding value, meat nutrients and associative effects of a diet comprised of various corn silages inclusion with peanut vine or wheat straw in finishing beef cattle. Methods: One hundred and eighty Simmental crossbred beef steers were blocked and assigned to the follow treatments: i) whole plant corn silage-based diet (control, WPCS), ii) mixed forages-based diet (replacing a portion of corn silage with wheat straw, WPCSW), iii) corn stalklage-based diet (CS), and iv) sweet corn stalklage-based diet (SCS). Each group consisted of 5 repeated pens with 9 steers/pen. The diets were formulated to be isonitrogenous and isoenergetic with same forage to concentrate ratio. Experimental diets were fed for 90 d. Results: The effective ruminal degradability of dry matter and crude protein were highest for WPCS diet (p<0.05), for neutral detergent fiber was highest in SCS diet (p<0.05). The average daily gain was greater for cattle offered the WPCS diet, intermediate with WPCSW and SCS and lowest with CS (p<0.001). The concentration of non-esterified fatty acid in serum was higher for steers fed with CS and SCS diets than those offered WPCS and WPCSW steers (p<0.001). The treatments did not affect the general nutritional contents and amino acids composition of Longissimus dorsi of steers (p>0.05). Conclusion: The corn silage-based diet exhibited the highest feeding value. The sweet corn stalklage and wheat straw as an alternative to corn silage offered to beef cattle had limited influence on feeding value and meat nutrients. However, the value of a corn stalklage-based diet was relatively poor. To sum up, when the high quality forage resources, such as corn silage, are in short supply, or the growth rate of beef cattle decreases in the later finishing period, the sweet stalklage and wheat straw could be used as a cheaper alternative in feedlot cattle diet without sharp reducing economic benefits.

A feeding trial was carried out to investigate the utilization of dietary soybean meal and wheat flour as substitutes for fish meal and alginate in different dietary types (powder, pellet and flake) for juvenile snail (Semisulcospira gottschei). After 10 weeks feeding trial, survival was not affected by formulation and type of diets (P>0.05), but weight gain was significantly affected by dietary formulation (P<0.001) and type (P<0.05). In the same dietary formulation, weight gain of the snail fed the flake type of diets was lower than that of the snail fed the powder or pellet types. However, the type of diet did not affect weight gain when snail fed diets containing $37\%$ soybean meal and $18\%$ alginate. The weight gain was lower in the snail fed diets containing $25\%$ fish meal compared with that of the snail for diets containing $33-37\%$ soybean meal at the same dietary type. When soybean meal was used as main protein source in diets, weight gain was not affected by dietary alginate $(0\;and\;18\%)$ and wheat flour $(36\;and\;58\%)$ contents. Crude protein and ash contents of whole body of the snail was not affected either by formulation or by type of diet. Moisture and crude lipid contents of the whole body were significantly affected by dietary formulation, but not by the type. These results indicate that $25\%$ fish meal could be replaced by $37\%$ soybean meal as dietary protein source, and pellet and powder could be desirable dietary type for the optimum growth of the snail.
Riboflavin in the various materials which used for Takju brewing was determined and its quantitative changes in the Takju mashes which were mashed with polished rice and wheat flour respectively using Nuruk only for enzyme source, and with wheat flour and corn powder respectively using Nuruk and Koji, were checked at 24 hours intervals during the whole brewing period.

The quality and sensory characteristics of Misutkarus, made from immature-whole green rice (IWGR) and barley (IWGB), and their cookies were assessed. Misutkarus of IWGR and IWGB showed a significantly higher water absorption index and viscosity, as well as higher hydrolysis rate by ${\alpha}$-amylase, resulting in higher amount of reducing sugar than those of mature brown rice and barley. The cookies made with 30% Misutkarus of IWGR and IWGB showed harder texture, lower spread ratio, darker and more reddish color than cookies with 100% wheat flour (control). For sensory evaluation, the beverage was prepared by mixing Misutkarus, milk and honey, and the beverages of IWGR and IWGB could not provide acceptable sensory quality due to reduced nutty taste and stronger greenish aroma. However, when added to prepare cookies, 30% Misutkarus of IWGB imparted the favorable taste, aroma, texture and overall preference by presenting no significantly different sensory characteristics with wheat flour.

This study was carried out to analyze winter cereal crops for harvest time, proper drying time and haylage quality in order to investigate the possibility of the production of good quality haylage substitute for hay. As a result, in case of productivity and feed value, dry matter yield and TDN yield was increased with late harvest and crude protein and NDF, ADF was decreased (p<0.05). To make haylage for whole crop barley, oats, triticale, whole crop wheat need more than 32 hour wilting time in the milk ripe stage, yellow ripe stage need about 8~24 hour, and wilting time did not need the full ripe stage. Rye does not suitable for making haylage because of difficulty pre-wilting time. In case of fermentative quality on haylage, pH was increased with late harvest on all winter cereal crop forage. Lactic acid content was decreased with late harvest (p<0.05), and highest in the milk ripe stage. Acetic acid was also decreased with late harvest, and butyric acid was not detected. In conclusion, to harvest sooner of winter cereal crops could be an efficient way when making haylage in terms of protein content and fermentation quality. Ray can used as fresh and silage, because difficulty for pre-wilting time in Korea. Whole crop barley, oats, triticale, wheat can be used haylage when harvested yellow ripen stage and pre-wilting time for 8~24 hours.
This study was investigated the quality characteristics of muffins which were prepared with whole waxy sorghum flours. Muffins were made with different sorghum flour contents of 10, 30, 50 and 100% substitution for wheat flour. The crude protein and fat contents of muffins were not different among samples, but the crude ash content was determined to increase with increasing content of sorghum flour. The specific gravity of the sorghum muffin batter as well as the weight and uniformity index of the sorghum muffins, were not significantly different from those of the control. The volume of muffins was found to decrease significantly when 100% sorghum flour was substituted for wheat flour. In terms of color, the L and b values of muffins were decreased with increasing contents of sorghum flour, and the a value was increased. The sensory test revealed that the hardness and adhesiveness of muffins was increased with the addition of sorghum flour, but springiness and chewiness decreased. According to the results of a sensory evaluation test, the flavor, taste and texture of muffins were reduced with the addition of 50 and 100% sorghum flour. The appearance and overall acceptability of sorghum muffins were not found to be different significantly from those of the control, up to 30% level substitution with sorghum flour.
Fifteen sheep were used in a trial which compared the feeding value of whole barley gain and cottonseed cake as supplements to a basal diet of leaves of fourwing saltbush (Atriplex canescens). Diet SB contained 700 g (air-dry matter) of saltbush alone, diet SB + BG contained 700 g SB with 400 g whole barley grain and diet SB + CS contained 700 g SB with 400 g cottonseed cake. The digestibility of the dry matter of diets SB (69%) and SB + CS (70%) were lower (p < 0.001) than of diet SB + BG (76%). Sheep offered SB alone daily lost 80g whereas those fed the other diets gained 11 g (SB + CS) or 17 g (SB + BG) per day. Daily water consumption of the sheep offered the three diets was similar (p > 0.05), but their water consumption was higher (p < 0.001) than that of sheep offered daily 700 g wheat straw and 200 g barley grain. The results indicate that, at the levels of feeding used, barley grain and cottonseed cake had similar value as supplements to fourwing saltbush harvested in summer. The addition of the supplement allowed the sheep to gain some live weight. However, the presence of saltbush leaves in the diet resulted in higher water intakes by the sheep.
This research was carried out to examine the substitutional feasibility of low-priced materials produced in waste of forest instead of wheat flour which is extended for plywood adhesives. Wheat, pine bark, wood flour and pine foliage of coniferous trees or poplar foliage of hardwood species were selected and pulverized into 60-100 mesh minute powder after they were dried at $100-105^{\circ}C$ during 24 hours in the drying oven. The prepared particles as above were added to urea formaldehyde resin, urea-melamine copolymer resin and water soluble phenol formaldehyde resin in the ratio of 10, 20, 30 and 50%. After plywoods were processed by the above extending ratios, shear strength of extended plywoods were analyzed and discussed. The results obtained at this study were summarised as follows; 1. In the case of urea formaldehyde resin, both dry and wet shear strength of plywoods extended by wheat flour were shown the highest value. 2. Dry shear strength of urea-melamine copolymer resin was better than that of urea formaldehyde resin on the whole, while plywoods extended by wheat flour were shown excellent results. 3. Among 10% and 20% extensions of urea-melamine copolymer resin, the best results were shown by poplar leaves powder, wheat powder and wood flour. They had no significant difference statistically. 4. In the case of water soluble phenol formaldehyde resin, although dry shear strength of pine leaves powder was higher than that of wheat flour in the ratio of 10%, there was no significant difference between them in the ratio of 10 and 20%. 5. Among 20, 30 and 50% extensions of water soluble phenol formaldehyde resin, wet shear strength of wood flour and bark powder was higher than that of wheat flour. Wet shear strength of wood flour in the ratio of 10% was shown the same tendency as above.
A study on the balance of essential amino acids in Korean diet and further investigation on quality of protein through optimum combination of foods using the least square method based on FAO/WHO (1973) provisional score patterns were carried out The results of the optimum gross combination are summarized as follows: 1) The first limiting amino acids of the Korean diet was found to be methionine and cysteine based on both whole egg and FAO/WHO (1973) provisional score patterns. 2) Weight ratios between rice and beef, chicken, pork, rabbit meat are 7 : 3, 4 : 1, 4 : 1, and 3 : 1. The amino acid score and the least amino acid are 100(phe+tyr), 99(thr), 111(trp), and 109(leu) for each combination. This result indicates that pork and rabbit meat can be high quality protein sources for the rice eating people. 3) Weight ratios between rice and anchovy, saury, ark shell, pollack, cuttle fish, tuna and herring are 2 : 1, 5 : 1, 3 : 2, 3 : 1, 3 : 1, 4 : 1, and 3 : 1. 4) Weight ratios between potato and rice, wheat flour are 8 : 1 and 24 : 1. Lysine, the limiting amino acid of rice and wheat flour can be complemented by combining these with potato. 5) It is possible to apply this idea on typical Korean dishes. For example, in case of soybean-sprout rice the optimum combinations of rice : soybean-sprout : pork and rice : soybean-sprout : beef are 4 : 1 : 1 and 11 : 1 : 5. It is of utmost importance to pursue further more desirable combinations with more complex food items and transform the result obtained by the computer analysis into more practical terms for practical use.
