To develop environmentally friendly bio-materials for animal feed, the potential of using mushroom was studied. Adding Flammulina velutipes cultivation media wastes (FCMW) has shown beneficial effects on broiler meat quality and production cost because of the $10{\sim}20%$ saving in feeds for broiler chicken. However, differences proximate composition between FCMW and commercial broiler chicken feed were observed. FCMW had higher contents of crude fat (6.2%) and crude fiber (13.7%) than the commercial broiler feed which had crude fat and crude fiber of 4.0%, and 6.0%, respectively. But FCMW crude protein contents were lower (12.2%) than those in commercial broiler (19.0%). Adding $5{\sim}10%$ of FCMW to broiler chicken feed increased amino acid concentration upto $33{\sim}38%$ in the meat, but adding more than 20% decreased amino acid concentration.

The purposes of this study were to provide the basic information on the cookies made with barley and oatmeal powder and to establish an optimum formula for the development of cookies with high content of fiber. Cookie samples were prepared with barley and oatmeal at various mixing ratios (2:0, 1:1, 2:1, 0:2), and the chemical properties, textural characteristics, and sensory properties of them were evaluated. The contents of carbohydrate and moisture of barley cookies were higher than oatmeal cookies, but the contents of crude protein, crude fat, crude ash and total fiber of oatmeal were higher than those of barley. The moisture content was the highest in the cookies of oatmeal and the lowest in barley-used ones. The cookie volume was increased by the addition of barley and oatmeal. The results of sensory evaluation showed that the cookies containing barley and oatmeal (2:1) was significantly more preferable in overall acceptability than the others. Hunter color test showed that the lightness was the highest in control, but the redness and yellowness were increased in the cookies with barley and oatmeal compared with the control.

This report described an outbreak of blindness caused by hypovitaminosis A in Hanwoo (Korean native cattle) in Gyeongsangbukdo province, Korea. The diagnosis was based on clinical findings, analysis of diet, and concentration of vitamin A and carotene in serum and/or feedstuff. Thirty eight of 48 cows were found to be affected. The causative diet contained higher levels of crude protein, net energy and crude fat and lower level of total fiber and crude fiber. Surprisingly, vitamin A was not detected in the causative diet. Treatment of vitamin A to Hanwoo that had blindness did not induce further progress of the symptom. Furthermore, there were no additional diseases detected. Based on the observations described above, this case was diagnosed as hypovitiminosis A.

The contents of starch, moisture, crude protein, crude fat, crude fiber, and ash of different varieties of various crops such as brown rice, barley, corn, sweet potato were analyzed. The average starch contents of brown rice, barley, corn, and sweet potato were $70.1{\pm}0.4\;{\sim}\;72.2{\pm}2.1$, $68.7{\pm}0.2\;{\sim}\;71.4{\pm}1.2$, $67.6{\pm}0.8\;{\sim}\;69.4{\pm}1.8$, and $21.7{\pm}0.9\;{\sim}\;28.3{\pm}0.5%$, respectively. The ground powder of each starchy substrate was suspended in distilled water, and then liquefied, saccharified, and fermented by dried active yeast at 32 for 4 days. By statistical analysis, the effectiveness of the contents of the different components such as starch, moisture, crude protein, crude fat, crude fiber, and ash of the crops on the ethanol production were examined. The results showed that the starch content positively affected the ethanol production in all the tested cereals and sweet potato. In brown rice, ash content affected negatively the ethanol production. In barley, protein content affected negatively the ethanol production, while fiber content affected positively the ethanol production. The sweet potato containing higher content of moisture produced less amount of ethanol.

We examined the forage quality to provide the basic information for the utilization of blackberry by-products (leaf and stem) among thirty-five mutant lines derived from gamma-ray. The leaves had higher crude protein (CP) contents than stems. In addition, the leaves showed broad ranges of variation in crude fat, crude fiber and crude ash. The overall forage quality of the stems were similar to those of the original variety. The mean of neutral detergent fiber (NDF) content of leaves and stems in mutant lines were 25.88% and 58.98%, respectively. Also, the mean of acid detergent fiber (ADF) content of leaves and stems in mutant lines were 15.43% and 49.27%, respectively. Forage quality grades of all blackberry leaf were special quality class. However, the blackberry stem ranked $1^{st}$ to $5^{th}$ in quality class. The stem diameter was negatively ($P{\leq}0.05$) correlated with the moisture and crude protein. Also, the fruit length was highly negatively ($P{\leq}0.01$) correlated with the RFV (relative feed value) in blackberry leaf. The one hundred fruit weight was highly negatively ($P{\leq}0.01$) correlated with the crude ash. Based on these results, the by-products of blackberry could provide high quality forage for feeding of live stock.

This experiment was conducted to clarify the plant growth promoting effect of compost supplemented with cultured solution of photosynthetic bacteria(Rhodopseudomonas capsulatus) before sowing on the early growth of plug seedling of tomato and to evaluate the optimum concentration of bacterialization. Bacterializing concentrations(v/w) to the compost were 2%, 3.3%, 10%, 20% and 50%, respectively. Plant growth in terms of plant height, stem diameter, leaf area, total fresh and dry weight were promoted by the bacterialization of photosynthetic bacteria. Especially, in the plots supplemented with 10 to 20% the early growth was promoted markedly over 2 times. Compositions of photosynthetic bacteria consisted of crude protein 60.7%, soluble carbohydrates 20.1%, crude fat 7.6%, crude fiber 3.2% and crude ash 4.8, respectively.
