To develop the health/functional food materials, we investigated the cultural condition of mycelial growth on the solid state fermentation using the brown rise, Acanthopanax sp. and Artemisia sp., and also evaluated inhibitory activity of angiotensin converting enzyme (ACE) of hot water extracts from cultured media of Pleurotus eryngii. As the amount of Acanthopanax nnd Artemisia In the cultural media increased, the mycelial growth rate decreased. Especially, addition of Aeantopanax showed marked effect than Artemisia. Moisture contents in three kinds of cultured media were in the range of $10.9{\sim}12.0%$. Crude protein fat and crude fiber content were the highest value in cultured brown rice medium, whereas the mineral contents (Ca, K and P) were higher in the Acanthopanax supplemented (5%) medium than the other media, The extraction yield of the Artemisia supplemented (5%) medium was the highest value of 4.80%, and the pH of hot water extract from cultured brown rice medium showed the lowest value of 6.1. Lightness (L) values in three kinds of extracts from cultured media were in the range of $85.8{\sim}87.1$. Redness (a) value was the highest In the brown rice and Acanthopanax supplemented media, however cultured Artemisia supplemented medium showed the highest value in yellowness (b). In comparison of sugar components analyzed by the thin layer chromatography with three kinds of samples, two spots were detected to be glucose and maltose, respectively. The ACE inhibitory activity of hot water extract from the cultured Acanthopanax supplemented medium showed the highest value at the concentration of $0.2{\sim}1.0\;mg/ml$. These results suggest that the Pleurotus eryngii grew in natural media using brown rice and Acanthopanax can be supplemented to the brown rice medium to enhance its ACE inhibitory activity as health/functional food materials.

This study examined the effects of feeding whole-crop barley silage (BS), corn silage (CS) and the mixture of BS and CS (CB) on feed consumption, daily gain, nutrients apparent digestibilities and blood parameters in order to investigate the feed evaluation in Korean black goats. BS, CS, and CB were fed to twelve Korean black goats, which were allocated into three groups in metabolic cages according to the latin-square design. As a result, dry and organic matter intakes for goats per day have shown a tendency to decrease in the order of CS, CB and BS, but there were no significant differences. We also found a similar tendency when the intakes of crude protein, crude fat, and non-fiber carbohydrates (NFC) were examined. However, ADF and NDF consumptions showed a decreasing tendency in the order of CB, BS and CS. Dry matter intakes per metabolic body weight showed the decreasing tendency in the order of CS (57.6g), CB (53.8g) and BS (52.7g), however with no statistical differences. Average daily gain of 64.2 g in CB was significantly higher than the other groups (42.0g to 46.0g). Nitrogen intakes and nitrogen retention showed a decreasing tendency in the order of CS, CB and BC. Nevertheless, nitrogen retention in CS group was higher by 30% than that of the BC group with p<0.05. Apparant digestibilities of dry and organic matters were 72.6 and 72.8% for the CS group respectively, which were significantly higher than those of the BS group (67.5 and 69.0%) and the CB group (66.0 and 67.1%). In conclusion, the results of this study demonstrated that the CS group showed more positive feed consumption, digestibility, and nitrogen retention in Korean black goats than those of BS group. The CB group, however, showed similar results to the results of the CS group.

This experiment was conducted to investigate the effects of molasses and $Phellinus$ $linteus$ meal supplementation on the quality of Korean herbal medicine silage. Herbal medicine meal silages were produced by the addition of 0, 15, and 30% of $Phellinus$ $linteus$ meal and 0, 1, and 2% of molasses ($3{\times}3$ factorial design) and stored for 40 days at room temperature. There were three replicates per treatment. Its quality such as chemical composition, pH, organic acids, the number of microorganisms and $in$ $vitro$ dry matter disappearance were determined. As the $Phellinus$ $linteus$ meal level increased, crude protein and crude fat contents increased significantly, but the acid detergent fiber (ADF) content decreased significantly. As the addition of $Phellinus$ $linteus$ meal decreased, and molasses increased, pH tended to decrease, but the lactic acid content trended to increase. The acetic acid content was lower in a higher level (30%) of $Phellinus$ $linteus$ meal, and higher in a higher level (2%) of molasses. As the $Phellinus$ $linteus$ meal level increased, the butyric acid content decreased, and butyric acid of molasses treatment was higher than that of non-supplemented control. Molasses increased the number of Lactobacillus, but decreased the number of fungi in silage. A lower level of $Phellinus$ $linteus$ meal increased the number of Lactobacillus, but decreased the number of fungi. $in$ $vitro$ dry matter disappearance tended to increase by the addition of $Phellinus$ $linteus$ meal and molasses. It is concluded that the addition of molasses and $Phellinus$ $linteus$ to herbal medicine meal silage could enhance its nutritional quality. It is considered that proper levels of molasses and $Phellinus$ $linteus$ meal in herbal medicine meal silage were 2 % and 15% respectively.

The contents of functional and nutritional components of 13 cultivars of Chinese cabbage (CC, $Brassica$ $rapa$ subspecies $campestris$) were analyzed to compare the effects of soil pH of the greenhouse (pH 6.2) and outdoor (pH 7.6). The CC cultivated on pH 6.2 (CC-6.2) soil contained significantly increased amounts (2-9 fold) of pectin, crude protein, vitamin C and vitamin E compared to the counterpart (CC-7.6). The contents of ash and the minerals (Ca, Fe, Na, and Mn) were also significantly increased in CC-6.2. However, CC-6.2 contained 40-50% lower contents of reducing sugars, cellulose and crude fat than CC-7.6. CC-7.6 contained more glucosinolates, gluconasturtiin (18.33 vs. $1.16nmol{\cdot}g^{-1}$ wet weight) and gluconapin (145 vs. $2nmol{\cdot}g^{-1}$ wet wt), than CC-6.2. In conclusion, CC-6.2 had an improved texture (high pectin and low cellulose) and nutritional value (high in protein, Ca, Fe, vitamin C, and E), whereas the CC-7.6 had better taste (high in reducing sugars) and anticancer functionality (high in glucosinolates).

In approximate composition, crude protein, lipid, ash, crude fiber, and N-free extract constituted 14.70%, 3.10%, 6.90%, 18.20%, and 57.10%, respectively, in Korean safflower flowers, compared to 12.60%, 2.70%, 5.80%, 16.40% and 62.50%, respectively, in Chinese safflower flowers. This indicated that Korean safflower flowers surpassed their Chinese counterparts except in terms of N-free extract. Free sugars such as fructose, glucose, and sucrose were proven to be dominant in both domestic and Chinese safflower flowers, while little xylose was contained. For content of polyphenolic compound, Korean safflower flowers contained 13.85% water soluble extract and 9.70% MeOH extract, compared to 9.39% and 7.04%, respectively, for the Chinese variety, confirming the higher levels in the Korean variety. For fatty acids, (Ed- the following results are not presented in ratio form) saturated fatty acids and unsaturated fatty acids comprised 6.80% and 93.20% in Korean safflower flowers and 16.0% and 84.0% in Chinese safflower flowers, respectively. Linoleic, oleic, and palmitoleic acids comprised 75.30%, 11.60%, and 3.40% in Korean safflower flowers, and 66.70%, 11.20%, and 6.10% in the Chinese variety, respectively. Of amino acids, essential amino acids comprised 46.67% in Korean safflower flowers and 36.79% in the Chinese variety. Moreover, total essential amino acids in Korean safflower flowers were higher than those of their counterparts. Non-essential amino acid comprised 65.17% in the Korean variety and 54.49% in the Chinese. In terms of mineral content, Korean safflower flowers contained more Ca, Cu, Fe and Mn than those of China, while Chinese safflower flowers contained more A1, Ba, Mg, K, Na, Zn, Sr and P.

This study was conducted to investigate the effect of probiotic from pine needle microbes on growth performance, blood characteristics, carcass traits and economy of pigs. One hundred eighty pigs (L${\times}$Y${\times}$D, average body weight=75 kg) were grouped and housed with 15 animals per pen for 3 replications per each treatment. The ingredients and pine needle microbes mixed and fermented on anaerobic condition for 10 days to make the fermented diet. The basal diet was substituted with 0 (CON), 3 (T1), 5 (T2) and 10% (T3) of fermented diet, the pigs were fed for 42 days and slaughtered at the end of the trial to measure the carcass traits. Crude protein concentration of fermented diet on 10 day was higher (p<0.05) than that of on 0 day, while crude fiber concentration and pH were lower (p<0.05). The supplementation of fermented diet did not affect on growth performance and feed intake. Hemoglobin concentration of whole blood in T3 was higher (p<0.05) than that of CON, and hematocrit concentrations in CON and T1 were higher (p<0.05) than that of T2 and T3. The concentration of platelet was higher (p<0.05) in T1 than in T2 and T3. The CON had higher (p<0.05) total cholesterol, LDL-cholesterol and triglycerides concentrations than the treatments, whereas lower (p<0.05) HDL-cholesterol concentration. Carcass weight and dressing in T1 and T3 were higher (p<0.05) than those of CON and T2. The backfat thickness was higher (p<0.05) in CON and T2 than in T3. The carcass grade and economy improved by supplementation of fermented diet compare to CON. In conclusion, the supplementation of fermented diet using probiotics from pine needle microbes could improve health and meat quality and reduce the feed cost of pigs.

This study was conducted to investigate the effect of supplementary feeding levels on livestck and forage productivity and grazing intensity in Elk stags (Cervus canadensis). A fifteen 2-year-old Elk stags about 195 kg were randomly assigned to one of three dietary treatments (five animals per treatment). The dietary treatments consisted of a feeding concentrate of 1.0% of body weight (T1), 1.5% of body weight (T2) and 2.0% of body weight. Total dry matter intake (TDMI) was increased with increased with an increasing supplementary feeding levels. Average daily gain (ADG) were significantly increased with an increasing supplementary feeding levels (p<0.05) and reached a maximum on July and was lower in spring than autumn. The velvet antler production was no differences among treatment groups. Forage productivity of pasture and crude protein content were highest on May and decreased thereafter, however, crude fiber content was the reversed. The grazing intensity of Elk stags was increased in spring (38 to 59 head per ha) than summer and autumn (13 to 32 head per ha). The average grazing intensity of Elk stags ranged from 21 to 34 head per ha, which is affected by supplementary feeding levels. This result suggests that feeding supplementary diet at 1.5 % of body weight was needed to maintain the stable wight gain in antler growing periods and control the proper grazing intensity of Elk deer stags.

This study was carried out from 2015 to 2016 to identify the suitable sowing and harvesting dates of summer crops in the mountain of Yeongnam, South Korea. The experimental design consisted of the different sowing and harvesting dates as follows: corn hybrid (Z. mays, Kwangpyeongok) of sowing (May 8, 19, and 27) and harvesting (August 10, 20, and 30); sorghum${\times}$sorghum hybrid (Sorghum bicolor ${\times}$ Sorghum bicolor, SS405) of sowing (May 27, June 19 and June 27) and harvesting (August 10, 20, and 30). In corn hybrid, ear rate and dry matter (DM) yield decreased (p<0.05) with the postponement of sowing date. Otherwise, ear rate and DM yield increased (p<0.05) with the postponement of harvesting date. Crude protein content decreased (p<0.05) with the postponement of sowing date, but neutral detergent fiber content increased (p<0.05). In sorghum${\times}$sorghum hybrid, plant length and DM yield with the postponement of harvesting date increased (p<0.05), while crude protein content with the postponement of harvesting date decreased (p<0.05). This study concluded that sowing corn hybrid in early May and sorghum${\times}$sorghum hybrid in early June then harvest in the middle of August was recommend to increase dry matter yield and feed value.
