To prevent the inappropriate treatment of livestock manure and induce the correct circulation of them into farmland, systematic monitoring and management by the treatment and circulation stage of livestock manure are required. The purpose of this study was to apply ubiquitous information communictation technology (u-ICT) to a livestock waste management system for better treatment by utilizing ubiquitous computing technology in the livestock sector. Elements and levels of applicable u-ICT technology for efficient livestock manure management were derived by analyzing previous researches. In addition, a conceptual diagram of an integrated management system was suggested by analyzing the existing liquid fertilization process.

This research investigated the effect of
concentrations and pH adjustment at the stage before land application, namely 2nd-aeration treatment stage of liquid fertilizer in the liquid fertilizer treatment process of swine manure on the physicochemical compositions of 2nd-aeration treated liquid fertilizer. The liquid fertilizer used in this research is the alkaline fermented liquid fertilizer of swine manure more than pH 9.0 through aeration treatment (Alkaline fermentation treatment group). About the alkaline liquid fertilizer, phosphate neutralization treatment was conducted with phosphoric acid and it was a phosphate neutralization treatment group. In 2nd-aeration treatment of liquid fertilizer for 30 days, each group was divided into alkaline treatment groups (T-1, T-2, and T-3) and phosphate neutralization treatment groups (T-4, T-5, and T-6) according to early
concentrations. The research results are as follows. 1. As for
reduction rate, the average 29.9% in alkaline treatment groups and the average 36.9% in phosphate neutralization treatment groups were shown and so the relatively high reduction rate was shown in phosphate neutralization treatment groups. 2. After finishing the experiment, the group of the lowest
concentrations was the phosphate neutralization treatment group, T-6 with the lowest inflow concentrations. In case the final goal level of 2nd-aeration treated liquid fertilizer is assumed as concentrations less than
3,000 ppm, it would be desired that inflow concentrations of 2nd-aeration treatment groups are adjusted less than
5,500 ppm. 3. As for the persistence rate of nitrogen, the average 29.3% in alkaline treatment groups and the average 38.9% in phosphate neutralization treatment groups were shown and so phosphate neutralization treatment groups showed the relatively low loss rate of nitrogen, meanwhile, in the case of T-P, phosphate neutralization treatment groups maintained high concentrations (average 1,473 ppm). 4. In the event of 2nd-aeration treatment of liquid fertilizer, "alkaline fermentation treatment" condition in 'low phosphate-low nitrogen' type and "phosphate neutralization treatment" condition in 'high phosphate-high nitrogen' type are expected to be favorable.

Since the temperature during summer is higher than the temperature which is suitable for milking cows, high temperature stress have severely affected dairy farmers due to decreased milk production. This study was carried out to investigate the effect of rainwater sprinkling system for reducing heat stress in milking cows during intense heat time. Treatment conditions were divided into 2 types ; No rainwater sprinkling (T1) and Rainwater sprinkling (T2). Temperature in the milking cow shed, feed intake, milk yield, respiration rate and rectal temperature were measured to investigate the effect of hot environment on the physiological, productive responses in milkig cows. The results obtained are summarized as follows : The daily milk yields were 24.5 and 27.4 kg per head in T1 and T2 during experimental period. The respiration rate was significantly higher in T1 than those of T2. The rectal temperature in T1 (
) was higher than those of T2 (
). It was suggested that rainwater sprinkling system installed in the dairy cow shed was effective means to reduce heat stress of milking cow.

This study was conducted to investigate the effect of storage time of manure on the concentration of odorous compounds. Levels of odorous compounds were measured from manure incubated in
for 6 wk in pilot chamber whose structure is similar to slurry pit. Levels of short chain fatty acids were decreased (p<0.05) by 4,159, 1,925, 844, and 483 ppm as storage time increased as 0, 2, 4, and 6wk, respectively. Transfatty acid level was not changed for 2wk but decreased (p<0.05) afterwards (levels were 250, 248, 151, and 61 ppm at 0, 2, 4, 6wk, respectively). Levels of phenol compounds were decreased (p<0.05) by 68, 48, 26, and 9 as storage time increased as 0, 2, 4, 6wk, respectively. Phenol concentration was increased whereas p-cresol level was decreased as storage time increased showing ratios of phenol and p-cresol were 6:94, 34:66, 51:49, and 67:33 at 0, 2, 4, and 6wk, respectively. Concentration of indole compounds was not different for 2wk but increased (p<0.05) after 4wk. The ratios of indole and skatole were 71:29, 42:58, 28:72, and 36:64 at 0, 2, 4, and 6wk, respectively. Skatole concentration was increased as storage time increased. Therefore, our current results indicate that levels of volatile fatty acid and phenol compounds were deceased but indole compounds were increased as manure storage time was increased.

This study was to performed to investigate the effect of horseradish powder and mushroom waste in fattening pig diet on odorous compound concentration from slurry. Twenty fattening boars [Landrace
Duroc] weighing an average body weight of
kg were randomly assigned to one of 4 treatments (control, horseradish 0.03%, mushroom waste 0.5%, and combination; horseradish 0.03% + mushroom waste 0.5%). This experiment was a randomized complete block (RCB) design using 5 pigs per treatment with 1 pig per metabolizable cage. Pigs were fed experimental diet (amount proportional to 3% of their body weight) twice a day (09:00 and 16:00) for 7 d after having 14 d adaptation period. Experimental diets were mixed with water by 1:2.5 v/v. Odorous compounds in slurry including acetate, propionate, butyrate, trans fatty acid isomers were not different (P>0.05) among treatments. There was no difference (P>0.05) in the levels of phenol compounds including phenol and p-cresol in slurry among treatments. Concentration of indole was lower (P<0.05) in horseradish group compared with others. Skatole level was highest in control and horseradish group, middle in mushroom waste group, and lowest in combination group (P<0.05). Concentration of indole compounds was lowest (P<0.05) in combination group. Data from our current study suggest that indole compounds in slurry can be reduced by administrating pigs with 0.03% horseradish powder and 0.5% mushroom waste in their diet.

This study was performed to test the effect of horseradish powder in fattening pig diet on odorous compound concentration from manure. Twenty fattening boars [Landrace
Duroc] weighing an average body weight of
kg were randomly assigned to one of 4 treatments (horseradish level in diets: 0, 0.01, 0.02, 0.03%) based on their body weight. This experiment was a randomized complete block (RCB) design using 5 pigs per treatment with 1 pig per metabolizable cage. Pigs were fed experimental diet (amount proportional to 3% of their body weight) twice a day (09:00 and 16:00) for 7 d after having 14 d adaptation period. Experimental diets were mixed with water by 1:2.5 v/v. Concentration of volatile fatty acids (VFAs) was highest (p<0.05) when pigs fed diet with 0.02% horseradish powder. Level of phenol compounds including phenol and p-cresol were decreased (p<0.05) in 0.01~0.02% horseradish treatment group compared with control group. Concentration of indoles including indole and skatole was lowest (p<0.05) in 0.03% horseradish treatment group compare to others. Therefore, results from our current study suggest that the optimal levels of horseradish powder in diet for reducing phenol and indole compounds in pig manure were 0.02 and 0.03%, respectively.

Effect of commercial Direct Fed Microbials (DFM) or protease treated feed (PTF) supplementation on growth rate and biogenic substances such as BUN, glucose, IgG, GOT, GPT and Vitamin A, C, E from Holstein steers was studied for 7 months. Thirty two steers aged 2~3 months were separated with 4 groups for control, DFM (PS), protease (ES) and their mix (PS + ES) supplementally fed 0, 100, 100 and 50 + 50 g/day respectively. Weight gain was averagely higher in PS than any others, although there were no differences significantly. All treatments enhanced to 3~8% of control in dry matter, crude protein and total digestible nutrient (P>0.05). Metabolic diseases with veterinary cure had not shown in this study. Plasma GOT and GPT were lower in the PS and ES than control. Plasma glucose concentration was also lower in PS than the others. Total cholesterol of ES was higher than the others but that of PS is the lowest. Plasma vitamin C was higher in PS than the others. It was shown that dietary PS affected change from glucose to vitamin C with not overloading liver. Conclusionally, PS and ES were shown to enhance metabolic health of steers during growing period.

We investigated the effect of the clay mineral fortified with complex trace elements by specific fermentation microbes on growth performance and a quality of pork in this study. For the declared experimental animal, 80 heads of crossbred with Large White and Yorkshire were randomly splitted into a control group and a test group. Each group were assigned with 4 replicates and 10 heads of each replicate. When 0.3% of the fermentation product of the clay mineral (FCM) was added into feed stuff and fed for 9 weeks of experimental feeding period, the results of the feed intake, weight gains, pH of carcass, lightness of meat color, and brightness of the muscle semimembranosus were similar to those of the control group. However, dressing percentage, reddishness of carcass, and water holding capacity were improved, respectively, as much as 2.7%, 12%, and 10%, and reduced by 6% in cooking loss. In order to investigate the immune modulatory effect of fermented clay mineral, pheripheral blood mononuclear cells (PBMC) were isolated and Immune modulatory parameters were measured. The proliferation activity of PBMC from pigs fed the fermented clay mineral were significantly increased compared to control group pigs, and also those results were more clearly observed as activated with lipopolysaccharide and concanavaline A. The secretion of TNF-
of the FCM group pigs showed an increasing tendency. Therefore it was suggested that the feeding of FCM which was high in cation metathesis and the value of infrared ray, activated the immune responses, and thus the production of the environment-friendly high quality pork without the use of antibiotics would be possible.

This study was conducted to investigate the effects of bedding thickness of sawdust on feed intake, blood metabolites concentration and environmental condition of cowshed floor for Hanwoo. Feed intake was increased at thicker bedding groups (15 or 20cm), compared with thinner bedding group (10cm). The thicker bedding had a positive effect on concentration of serum total protein, high density lipoprotein (HDL)-cholesterol, low density lipoprotein (LDL)-cholesterol and
-glutamyltransferase (GGT). Moisture content and the number of E. Coli in the bedding material were remarkably lower in 15 and 20 cm groups, compared with 10 cm group. Based on the data obtained in this study, approximately 20 cm bedding thickness or at least over 15 cm would be maintained to improve the health condition of Hanwoo and hence to enhance the productivity.

Nitrogen included in animal manure can be used as organic fertilizer if it is treated properly but it may cause serious air and water pollution without proper management. Significant amount of nitrogen losses happen in the form of ammonia when the manure staying in animal house and storage facilities and being composted and applied to the field. In order to maximize the manure nitrogen utilization, it is important to understand the mechanisms of nitrogen loss during the diverse manure handling and treatment procedures. The plant available nitrogen portion of total nitrogen in excreted manure was evaluated based on animal type, animal manure collection system, manure treatment process, and application method. About 27% of nitrogen included in excreted pig manure could be plant available if it is applied to the filed after composting process. The plant available nitrogen portion varies from 29% (surface application) to 54% (solid injection) based on application method of digestated piggery slurry. Plant can use 18% of manure nitrogen if the composted cattle and poultry manure applied to the field using surface application method. Manure treatment and application methods need to be carefully selected to control and utilize the manure nitrogen properly.

This study was evaluated high end research grade Near infrared spectrophotometer (NIRS) to low end popular field grade multiple Near infrared spectrophotometer (NIRS) for rapid analysis at forage quality at sight with 241 samples of Italian ryegrass silage during 3 years collected whole country for evaluate accuracy and precision between instruments. Firstly collected and build database high end research grade NIRS using with Unity Scientific Model 2500X (650 nm~2,500 nm) then trim and fit to low end popular field grade NIRS with Unity Scientific Model 1400 (1,400 nm~2,400 nm) then build and create calibration, transfer calibration with special transfer algorithm. The result between instruments was 0.000%~0.343% differences, rapidly analysis for chemical constituents, NDF, ADF, and crude protein, crude ash and fermentation parameter such as moisture, pH and lactic acid, finally forage quality parameter, TDN, DMI, RFV within 5 minutes at sight and the result equivalent with laboratory data. Nevertheless during 3 years collected samples for build calibration was organic samples that make differentiate by local or yearly bases etc. This strongly suggest population evaluation technique needed and constantly update calibration and maintenance calibration to proper handling database accumulation and spread out by knowledgable control laboratory analysis and reflect calibration update such as powerful control center needed for long lasting usage of forage analysis with NIRS at sight. Especially the agriculture products such as forage will continuously changes that made easily find out the changes and update routinely, if not near future NIRS was worthless due to those changes. Many research related NIRS was shortly study not long term study that made not well using NIRS, so the system needed check simple and instantly using with local language supported signal methods Global Distance (GD) and Neighbour Distance (ND) algorithm. Finally the multiple popular field grades instruments should be the same results not only between research grade instruments but also between multiple popular field grade instruments that needed easily transfer calibration and maintenance between instruments via internet networking techniques.
