This study was conducted to investigate the effects of dietary silicate minerals on ammonia emission from the excreta and performance in laying hens. A total of one thousand and twenty 49 week-old Lohmann brown layers were divided into three treatment groups consisting two replicates of 170 birds each. The experimental diets were containing three kinds of silicate minerals (Sand, Na-bentonite and SY feldspar) added at the level of 2% by top-dressing. Ammonia emission from the excreta was significantly decreased (p<0.05) by the supplementation of Na-bentonite or SY feldspar. N concentration of the excreta was significantly higher (p<0.05) for the hens fed Na-bentonite or SY feldspar compared to those fed sand. However, no significant differences were observed in feed intake and laying performance with over 80% laying rate observed for all the treatments. Egg shell strength was diminished when SY feldspar was added to the diet. As a whole, the results obtained from the experiment indicated that supplementation of Na-bentonite or SY feldspar added at 2% to the laying hen diet should not affect laying performance but help to reduce ammonia from the excreta at the same time.

The aim of this study was to investigate the removal effects of the color, nutritive salts and other pollutants on piggery slurry by advanced oxidation process (AOP) system. The experimental AOP system was designed to treat 300 L of piggery slurry per hour. To enhance oxidizing power of the experimental APO system, a ultraviolet irradiation system and the ultrasonic system were attached to the AOP system. With 5 min ultrasonic treatment, COD, SS and T-N concentrations were changed from 210, 820, and 309 to 200, 760, and 262 mg/L, respectively. With 10 min ultrasonic treatment, SS and T-N concentrations tended to decrease but T-P concentration was not changed. With the treatment of both ozone and ultrasonic waves for 30 min, COD, SS, T-N and T-P decreased from 238, 900, 400, and 5 to 165, 540, 263, and 4 mg/L, respectively. With the treatment of both ozone and ultraviolet irradiation for 30 min, COD, SS, T-N and T-P decreased from 321, 340, 204, and 15 to 151, 140, 111, and 7 mg/L, respectively, and color was changed from 4,344 to 624.

The pig slurry is one of important fertilizer source for production of crops in recent years, but it has many controversial points of utilization such as offensive odor, lack of spread equipment and farmland possession, respectively. This study was carried out in order to remove water pollutants and malodor of pig slurry using biofiltration system. The biofiltration system consists of pig slurry separator, mixing shift and attached blade for sawdust or ricehull, air injection nozzle and outlet for pig slurry and sawdust or ricehull. The characteristics pH,
(Biochemical Oxygen Demand),
(Chemical Oxygen Demand), SS (Suspended Solid), T-N (Total Nitrogen), T-P (Total Phosphorus) of the untreated pig slurry used in this study were 7.2, 34,450, 24,604, 71,000, 4,194,
, respectively. The
(Hydrogen Sulfide) concentration were 70.0, 9.6 ppm, respectively. The initial total microorganisms of pig slurry were
, and Salmonella, Bacillus were
, respectively. The filtration system was very effective on removal of water pollutants of pig slurry. The removal efficiency of the offensive odor of ammonia and hydrogen sulfide in sawdust was higher than those of ricehull. The total microorganisms and bacillus of pig slurry are on the increase by sawdust and ricehull, but Salmonella showed a tendency to decrease in number after that time. Accordingly, the filtration system was very effective to produce a good quality pig slurry.

This study was conducted to develop an prototype automatic feeder (AF) for growing-finishing pigs. The main components of AF were a feed storage hopper, a feeding motor, a feed agitator, a control box and a programmable IC, which were controlled by a personal computer. The powder type feed transfer rate of AF was average
. In feeding test, growing pigs (Landrace) of about 43 kg live weight were used in the study, and was fed over a 6 weeks in pens with solid concrete floors. For feeding trials with AF, the operation time of the feeding motor was set to 2, 3, 4, 5, and 6 seconds per feeding. Pigs frequently used AF from 05:00 to 11:00 and from 11:00 to 17:00 without relationship to the operation time of the feeding motor. The AF operation time of the feeding motor to minimize feed loss was between 2 and 4 seconds. Pigs fed with AF had same or slightly higher average daily gam (0.8~0.9 kg) than that with a commercial feeder, and average daily feed intake (2.76~2.93 kg) and feed conversion ratio (3.10~3.66) of pigs fed with AF were same or lower than those with the commercial feeder except the operation time of the feeding motor set to 6 seconds. As a result, AF would help to use and improve the productivity of growing-finishing pigs.

A study was conducted to determine the effects of seed mixture and nitrogen application levels on botanical composition and forage productivity in grazing pasture. Legume forage have the ability to take nitrogen from the atmosphere and convert it into a form usable by plants. Including legumes in mixtures with grass lowers the amount of nitrogen fertilizer required to produce forages. Dry matter (DM) yield of grass-legume mixtures was more than that of grass mono-cultivated and grass+white clover+red clover mixtures was the highest as 17,391 kg/ha in legume mixture (P<0.01). The highest DM yield was in N-200 kg/ha, but it was similar between N-100 kg/ha(15,128) and N-200 kg/ha (16,017). The large decline in the proportion of grass during April to June in 2004 probably was due to the drought and summer depression in grass-legume mixtures. Grass proportions decreased by 8.2% after 2 year, and white clover was dominated in grass-white clover mixture by May 2005. Crud protein (CP) content tends to increase with increased nitrogen application level.

The best way to treat livestock manure is to recycle as much as possible. The composting of livestock manure is a safe and economical treatment process. This study was carried out to investigate decomposition effect of pig manure by adding fermented compost. The fermented compost was added in pig manure mixed with sawdust as an inoculator, and the mixture was fed to composting reactor. Supplemental levels of fermented compost on the pig manure mixed with sawdust were regulated at 5, 10, 15 and 20% (V/V) respectively. The results were as follows ; 1. In all cases, PH range was between 7.6~9.05 during composting period. 2. The highest temperature and the long duration of thermophilic stage were observed in control treatment. 3. The number of microorganism reached at maximum on day 4, which recorded the highest temperature 4. Compost pile mixed with 10% of inoculator (fermented compost) showed the highest C/N ratio reduction.

The objective of this study is to predict the expansion possibility of treatment capacity in public livestock manure treatment plant (PLMTP) integrated individual farmhouses. According to the treatment efficiency and cost reducing effect, expansion possibility was examined using three cases; (i) decrease of influent concentration from 20,000 mg/L BOD to 1,000 mg/L BOD, (ii) maintenance of low concentration influent with minimum revising existing facilities (BIOSUF) and (iii) maintenance of low concentration influent without revising existing facilities (liquid corrosion method, LCM). In BIOSUF, the treatment capacity increased from 130 ton/day to 300 ton/day. Also, LCM resulted in expansion of treatment capacity from 210 ton/day to 250 ton/day while that of designed concentration influent decreased from 210 ton/day to 190 ton/day. The treatment costs were 14,674 won/ton and 9,929 won/ton for BIOSUF and LCM, respectively. After some revisions, it will be changed to 7,221 won/ton and 8,277 won/ton. Therefore, it must be considered that the livestock manure treats to low concentration and flows into PLMTP for the efficient operation and reducing treatment cost.

The effects of the processing mixture of pig manure and various organic wastes on the growth, cast production of earthworm, and conversion of organic matter to earthworm tissues by vermicomposting. The substances used in this experiments were sawdust, rice hull, coffee waste, brewery waste, litters, turfgrass cutting residues, rice bran, vegetable wastes and rice straw and were mixed with pig manure at a ratios of 50:50 (v/v), and pig manure 100% (control), respectively. The highest values of growth parameters, cast production and conversion efficiency of organic matter to earthworm tissues were obtained at the mixtures of pig manure with coffee waste, it may due to the favourable diet conditions to process with pig manure by vermicomposting. But, all of the earthworm died in the pig manure 100% (control) and pig manure with vegetable wastes treatments by vermicomposting was impossible in this experiment. The vermicast contained a higher values of total nitrogen, available phosphorus, exchangeable cations and cation exchange capacity than their parent materials with increased availability of nutrients and improved physicochemical properties.
