  • Dietary proteins are the most important factors affecting growth performance of fish and feed cost. Generally, most of the formulated diets for marine fish include a large amount of fish meal as a protein source because of its high nutritive value and palatability. Quality of fish meal in diet may affect on growth and feed efficiency of fish. Therefore, this study was conducted to evaluate the effect of various fish meals as dietary protein source on growth and feed utilization of the juvenile flounder. (omitted)

  • This study aimed to examine the fermentation quality of a tropical Elephant grass (Pennisetum purpuereum) and temperate Italian ryegrass (Lolium multiflorum) forages ensiled additive of fermented juice of epiphytic lactic acid bacteria (LAB) and to determine what factor affects the fermentation characteristics of the crops. In both species cell walls neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents in silages were consistently decreased (p<0.05) with the addition of FJLB at ensiling more then Control treatment. The FJLB additive increased number of LAB (cfu) and lactate concentration in the silages in both species. The Control treatment without additive underwent a clostridial type of fermentation with traces of propionic, iso-butyric, n-butyric acids contents with higher (p<0.01) levels of volatile basic nitrogen (VBN %TN) and had appreciable decreased of nutrient in silages. FJLB treatment improved silage nutritive value with little contents of VBN %TN, ethanol and very small amount of dry matter (DM) and hemicellulose losses (p<0.05) between 2 to 5% and 7 to 3% respectively, in Elephant grass and Italian ryegrass species. The results in this study indicates that while among the factors affecting silage fermentation butyric type of fermentation was more pronounced in tropical elephant grass compared to the temperate Italian ryegrass, FJLB additive revealed a better silage fermentation products in both species.

  • A field experiment was carried out to determine the effects of conditioning methods and tedding frequency on the drying rate and quality of Italian ryegrass hay. Italian ryegrass was cut with three types of mower conditioners (un conditioned, impeller, roller) and tedded with rake-tedder once or twice daily during field curing. The field drying rate of Italian ryegrass hay was the highest in roller conditioner. Conditioning treatment shorten the date from 1 to 1.5 compare with unconditioned. Drying rate of Italian ryegrass plant had been affected by tedding frequency within 3 days after it was cut, but it was ineffective after 3 days. There is no effect on acid detergent fiber (ADF) and neutral detergent fiber (NDF) but effect crude protein (CP) and relative feed value (RFV) by conditioning treatment in nutritive value of Italian ryegrass hay.

  • The objective of the study was to measure the beneficial effects of lactic acid bacteria (LAB) inoculation on the nutritive value of oat silage collected from thirteen regions in the Republic of Korea. The contents of crude protein, acid detergent fiber (ADF), neutral detergent fiber (NDF) and crude ash (CA) were slightly lower in LAB inoculated silage when compared with the control silage, whereas inoculation of LAB resulted in increased total digestible nutrient (TDN). Higher number of LAB, but lower count of yeast and fungi indicated the effectiveness of the LAB inoculation on oat silage fermentation. LAB inoculation resulted in low pH silage, which may prevent undesirable microbial growth. The LAB inoculation promoted lactic acid dominant fermentation with marginal levels of acetic acid and butyric acid in oat silage. These data suggest that the LAB inoculation may preserve oat silage at better quality for ruminant animal production.

  • Fresh rice straw silage (RSS) was prepared with lactic acid bacteria (LAB) and chlorella (CA) at the experimental field of National Institute of Animal Science, Cheonan Province, Korea. This experiment consisted of the following eight treatments: control treatment without CA and LAB; treatment of 0.1% CA applied without LAB; treatment of 0.5% CA applied without LAB; treatment of 1.0% CA applied without LAB; treatment of only LAB inoculation without CA; treatment of 0.1% CA inoculated with LAB; treatment of 0.5% CA inoculated with LAB; and treatment of 1.0% CA inoculated with LAB. The content of crude protein of RSS significantly elevated with increased concentration of CA (p<0.05). The levels of acid detergent fiber (ADF), neutral detergent fiber (NDF), total digestible nutrient (TDN), and in vitro dry matter digestibility (IVDMD) showed no significant improvement in all treatments when compared to control. However, the quantity of lactic acid in RSS increased in CA and LAB alone inoculated treatments. Similarly, lactic acid significantly increased in LAB with CA treatments when compared to control. In addition, the number of LAB in LAB treatment increased as compared to control and significantly increased by an increase of CA concentration (p<0.05). Therefore, the nutritive values and quality of RSS can be improved by the addition of CA.

  • Background : Evidence-based guidelines are now used for enteral nutrition(EN) in neurosurgical intensive care unit patients who mostly depend on EN. This study compared and analyzed the nutritive conditions of patients before and after they underwent guideline based nutritional interventions in order to determine whether using these guidelines improved their calorie supply. Methods : Data on the patients' nutritional requirements, maximum calorie supply through EN, serum albumin level, and total lymphocyte count were collected and analyzed using SAS version 9.1.3. All the statistical analyses were performed at a significance level of P<0.05. Result : The maximum calorie supply through EN was $923.1{\pm}359.7$ kcal before the intervention and $1254.4{\pm}196.3$ kcal after the intervention; this difference was statistically significant(P<0.05). The ratio of nutritional requirements to maximum calorie supply through EN was $55.5{\pm}22.4%$ and $74.2{\pm}13.9%$ before and after the intervention, respectively; this difference was statistically significant(P<0.05). This indicates a 19% increase in the ratio after the nutritional intervention. The serum albumin level also significantly increased from $2.7{\pm}0.6g/dL$ before the intervention to $3.2{\pm}0.4g/dL$ after the intervention(P<0.05). The total lymphocyte count slightly increased from $1267.7{\pm}728.2cells/mm^3$ before the intervention to $1801.9{\pm}1211.5cells/mm^3$ after the intervention; this difference was not statistically significant. Conclusion : The results showed that using the evidence-based feeding guidelines for interventions increased the calorie supply and improved the patients' nutritive conditions from moderate malnutrition to mild malnutrition.

  • This study was performed to investigate the effects of various parts of sorghum-sorghum hybrid (SSH) silage on nutritive values and qualities of SSH round bale silage and trench silage. SSH "SS405" was harvested at heading stages and ensiled. Samples of SSH silage used in this study were collected in three different parts (outer, middle and inner). The contents of crude protein (CP) and neutral detergent fiber (NDF), and in vitro dry matter digestibility (IVDMD) in SSH round bale silage showed trends similar to SSH trench silage. However, the contents of acid detergent fiber (ADF) and total digestible nutrient (TDN) in SSH trench silage appeared slightly an increased trend, as compared to SSH round bale silage. The contents of CP in inner parts of both SSH round bale silage and trench silage were lower than those of Outer and middle parts (p<0.05). However, The contents of NDF, ADF and TDN, and IVDMD were not different between the parts of SSH silage. The content of lactic acid in SSH round bale silage was significantly decreased (p<0.05), as compared to SSH trench silage. The content of acetic acid appeared an decreased trends, but there is not significantly different between SSH round bale silage and trench silage. In addition, the contents of lactic acid, acetic acid and butyric acid were not different between the parts of SSH silage.

  • To improve the low content of crude protein and low quality fermentation of napiergrass silage, ensiling with phasey bean was examined. Napiergrasses, (Pennisetum purpureum cv. Merkeron), hybrid napiergrass (Pennisetum purpureum${\times}$ Pennisetum typhoides) and phasey bean (Macroptilium lathyroides cv. Murray) were cultivated in Fukuoka, Japan. The first growth of napiergrasses and phasey bean were harvested at 90 days of age and chopped into about 1 cm lengths. The mixing levels of phasey bean with napiergrasses were 0, 25, 50 and 75; 700 g of plant materials were ensiled into a laboratory silo (1.0 litre. polyethylene container) and incubated for 30 days. After opening silos, pH, total nitrogen (TN), volatile basic nitrogen (VBN) and organic acids (lactic acid: LA, acetic acid: AA, butyric acid: BA) were determined. The experiment was a factorial design of $2{\times}4$ with 3 replicates. The data were analyzed statistically by two-way analysis of variance. Without inclusion of phasey bean, lower quality was observed for hybrid silage than for Merkeron silage. The inclusion of phasey bean at the rate of 25% increased DM and TN, and decreased pH value, VBN/TN, AA and BA in both Merkeron and hybrid napiergrass silages. The value of pH, TN, VBN/TN, AA and BA were not significantly different among 25, 50 and 75% mixing levels of phasey bean. LA production increased significantly with the increase in phasey bean mixing level in both hybrid and Merkeron silages. At all mixing levels of phasey bean, LA production did not show significant differences between Merkeron and hybrid silages.

  • To standardize proper formulation of urea and molasses, the former to increase crude protein content of tropical grass and the latter for improving its silage quality, we examined the fermentation quality of silage of fresh and wilted napiergrass (Pennisetum purpureum Schumach) with different levels of urea and molasses with or without lactic acid bacteria (LAB). Silage was made of napiergrass with conditions of fresh young (Exp. 1),young wilted for half day (Exp. 2) and fresh mature (Exp. 3). Chopped plant materials of about 1cm length were ensiled into a laboratory silo and incubated for one month at $25^{\circ}C$. The treatments were the combination of 0, 0.2 and 0.6% of urea and 0, 2 and 5% of molasses (fresh material basis) with or without LAB inoculation. After opening the silo, pH, organic acids, volatile basic nitrogen (VBN) and total nitrogen (TN) were determined. Addition of molasses significantly (p<0.01) lowered pH values in three experiments. Though molasses addition increased lactic acid production even at a higher level of urea, pH values at 0 and 2% molasses were significantly increased by urea in fresh and wilted young silages, but in fresh mature silage it occurred only when molasses was not added. VBN/TN at 0.6% urea were decreased significantly by the highest molasses in three experiments. Significant increases in TN by the increasing of urea addition were observed at all levels of molasses in wilted young and fresh mature silages. In conclusion, a combination of 5% molasses and 0.6% urea could improve the nutritive and fermentation qualities of napiergrass silage under young, wilting and mature conditions.

  • This paper mainly focuses on the research of the monitoring data about the total nitrogen (TN), total phosphorus (TP) of ten monitoring points of Hongze Lake in 28 years. Our study adopts the technical methods such as difference comparison, correlation analysis, Mann-Kendall, etc. to analyze the statistical characteristics, regional differences, and temporal and spatial variation condition of ten monitoring points of Hongze Lake in 1986-2013 as well as the reason for the time and space variation of TN and TP. The results show that the TN and TP of Hongze Lake change dramatically during the period of 1994-2004. In all the monitoring periods, TN and TP of the HZ5, HZ6, HZ7, HZ8 monitoring points in the estuary surrounding the Huaihe River are the highest, which suggests that TN and TP of Hongze Lake should not be ignored for the pollution along the Huaihe River. The TN concentration in the core area is the highest, but that in the development control area is the lowest. In most of the years, TN concentration is higher than 2 mg/L, and the water quality is V class and poor V class water quality in China's Environmental Quality Standards for Surface Water (GB3838-2002). TP concentration of the three areas is basically close, that is lower than 2 mg/L in most of the years, and the water quality is within the V class. The TN and TP concentration of Hongze Lake decreased and intensifying trend of eutrophication is controlled after 2004.
