This study was carried out to measure the environmental related parameters from two types of swine houses. Indoor temperature, relative humidity, carbon dioxide level, ammonia concentration and emission were measures every 2 minutes from each house with portable monitoring units. Carbon dioxide concentration balance was used to estimate the ventilation rates of the different houses. Daily ammonia concentrations in the growing-finishing and farrowing houses ranged from 2 to 17 ppm and 6 to 15 ppm respectively. The daily ammonia emission rate from the manure averaged 4.37 g/h
500 kg from growing-finishing house and 4.82 g/h
500 kg from the farrowing house. The above findings proved that summer season was associated with higher ammonia emission rates due to higher ventilation rate and ambient air temperature.

The round bale wrappers are generally used for rice straw after the harvesting of low land rice by combine harvester. In this situation, the bale wrappers should be well adapted under the travelling over raised borders and temporary ditches in soft soil of narrow rice fields. The study was conducted to improve the performance of bale wrapper through the new design for compact size, lowered gravity center and lowered power consumption. The prototype of round bale wrapper had been designed and assembled to tractor with three point hitch mounted. The machine type is one roll driving system with one roll for rotating and one roll for wrapping. The driving torque and work performance of the machines were measured and analysed. The torque requirement of the prototype and conventional type was 6kgf-m and 12kgf-m, respectively. The prototype shaved less friction resistance between bale driving roll and round bale. and the power requirement can also be reduced from 12kgf-m in the conventional to 6kgf-m in the prototype. The work efficiency of the new bale wrapper was
higher than the conventional wrapper, and the working cost of the prototype can be reduced
than that of the conventional.

Journal of Animal Environmental Science, volume 11, issue 1, 2005, Pages 17~24
Aerobic sequencing batch reactor (SBR) was used to treat screened dairy wastewaters. The study examined the production of volatile organic compounds (VOCs) and volatile fatty acids (VFAs) in the aerobic SBR and raw manure effluent storage over 35 days. The reduction of total VFAs in the aerobic SBR was over
removal than that of the raw manure. Acetic acid production in the aerobic SBR and the raw manure effluent storage were kept 138 and 286 mg/L. The propionic acid in the aerobic SBR was 1.9 mg/L, while the raw manure effluent storage was 68 mg/L, respectively. The concentrations of VOCs in the aerobic SBR reactor and effluent fill down remarkably than the raw manure storage. The results confirmed that the aerobic biological treatment is an essential requirement for minimizing odor problems.

The study aimed to develop a tractor drawn animal slurry manure sub-soil injector for arable land and thus, can reduce the waste management cost through effective treatment and utilization of animal slurry manure. The application of animal slurry manure to agricultural land will probably be one of the most effective ways to enrich the soil with vital nutrients. However, some existing slurry manure spenders are not suitable in the field because of their adverse effects to the environment. Based on this premise, a prototype was designed and assembled using 5 sub-soiling standards attached to the sin injector device. The traction force of the Prototype measured in the depth of 10 cm and 15 cm from the ground surface of a paddy field was 1,062 kgf and 1,214 kgf, respectively. A unique feature of the machine was that there was an equal volume of slurry manure flowing from each delivery pipe and regulated by a pressurized container that was likewise synchronized with the speed of the tractor The sub-soiling manure injection system can mitigate or reduce the harmful emission of obnoxious gases and malodor during the injection operation.

The objectives of this study were to develop an image processing algorithm for finding the sick or the dead layers(SDL) rearing in the multi-tier layer battery, which is a core technology of remote monitoring systems for layers, and to test the performance of algorithm developed in the experimental poultry housing. Based on the literature study and experiment, the standing up of layer was set as a criterion for judging layers whether sick or dead. Then, by the criterion set, an algorithm was developed. The image processing algorithm developed was tested how well it could and SDL at the experimental poultry housing. Test results showed that its monitoring correctness of layers standing up in the cages having all healthy layers was
in the cages having SDL. Therefore, it would be concluded that the image processing algorithm developed in this study was well suited to the purpose of development.

A field survey was conducted to determine the concentration of odor compounds from pig buildings and that were 20 meters within the boundary area. The odor compounds were measured from large, medium and small farms with enclosed and open housing systems and slurry and sawdust manure fermentation treatment methods. Among the odor compounds investigated, ammonia (
) had the highest concentration at 0.9
21.0 ppm followed by Hydrogen Sulfide(
) with a wide variation concentration of 51.9
6,712.4 pub, Uethylmercaptan(
) with non-detectable (N. D.)
12.9 ppb, Dimethylsulphide(
), with N. D.
5.2 ppb and Dimethyldisulphide(
) with N. D.
2.6 ppb. Considering the prevailing wind direction and air velocity ranging from 0.23 to 0.73 m/s within the boundary area, the odorous matters;
4.5 ppm, 0.01
0.06 ppb, N. D.
0.009ppb, N. D.
0.002ppb and N. D. for
respectively. These findings suggested that the Odor compounds
had the lower detection in the boundary area whilst
had no detection level within a 20-meter distance only. However, with these results odor compounds from pig buildings has to be further investigated under more controlled environmental factors.

This study was conducted to determine the odor reduction efficiency of a biofilter desist using different filter materials. The summary of results are as follows; 1. The airflow penetration rate of the different filter materials namely; rice straw, woodchips, rice hulls and sawdust were 0.72 m/s, 0.64 m/s, 0.48 m/s and 0.17 m/s, respectively. 2. The elimination of
gas was fastest in the rice hull at a rate of 4 mg/
followed by sawdust, woodchips and rice straw at 3 mg/
, 3 mg/
and 7 mg/
, respectively. 3. The filter material made of wood chips was able to eliminate the offensive gas known as
at a rate of 2.2 mg/
on the 7th day, 17.6 mg/
on the 21st day but decreased to 10.7 mg/
on the 36th day. In contrast, the filter material composed of sawdust had a continuous increase in the reduction of
at a rate of 12.3 mg/
on the 7th day, 18.3 mg/
on the 21st day and 20.1 mg/
on the 36th day. The above findings indicated that among the filter materials, sawdust was the most effective in absorbing
. Airflow penetration rate can be related to
odor elimination efficiency as shown by the slowest airflow rate of sawdust which is only 0.17 m/s.

A total of 4 trials were conducted to evaluate the nutritional value of food waste-byproduct feeds mixture(FWM) rotary drum-pasteurized and cured, to trace the nutritional flow according to the processing stages and finally to determine the optimal mixing formulation of feed ingredients for the growing pigs. Pasteurizing and curing FWM using a rotary drum drier resulted in little change in chemical composition and 8 to
of dry matter losses. Chemical change was affected by different feed ingredients used in each trial. Curding of FWM was caused probably by high moisture content, starch content and(or) physical characteristics of feed ingredients. The optimal mixing ratio of feed ingredients was food waste 45 : deepstacked broiler litter 10 : bakery by-product 22.5 barley bran 22.5. In conclusion, FWM rotary drum-pasteurized and cured had a satisfactory feed-nutritional value far growing pigs.
