  • To investigate the effects of inorganic phosphate ($P_2O_5$ 200kg/ha), fermented cow manures($P_2O_5$ 200kg/ha, 400kg/ha) and poultry manures($P_2O_5$ 200kg/ha, 400kg/na) levels mixed with sawdust on the soil changes and productivity of alfalfa monoculture, a field experiment arranged by randonmized complete block design was conducted at National Livestock Research Institute in Suwon, September, 1993 to December 1995. The results are as follows. S1. Soil pH was changed from 5.40(before experiment) to 6.17(fermented cow manure, $P_2O_5$ 400kg/ha), 6.76 (fermented poultry manure, $P_2O_5$400kg/ha) and 6.3l(inorganic phosphate, $P_2O_5$ 200kg/ha) at 0~5cm depth of subsoil, respectively. Organic contents after experiment were lower as a range of 2.41%~3.15% than those before experiment. 2. Total nitrogen contents of each treatment showed as 0.13%~0.16% at 0~5cm depth of subsoil comparing with before experiment(0.15%). Available phosphate content of inorganic phosphate($P_2O_5$200kgha) was highest as 405ppm. lowest as 125ppm(fermented poultry manure, $P_2O_5$ 200kg/ha) than before trial(205ppm). 3. K and Ca contents of after experiment were appeared to 0.22%~0.78% and 6.45%~9.45% comparing with before experiment(0.10% and 3.56%), respectively. 4. During two years, average DM yield of fermented cow rnanure($P_2O_5$ 400kg/ha) was highest as 11, 731kg/ha and lowest as 9, 017kg/ha at fermented poultry manure plot($P_2O_5$ 200kg/ha) with as sawdust, but no significant difference was found among treatment(P>0.05). 5. CP production, NEL and TDN yield of fermented cow manure($P_2O_5$ 400kg/ha) were highest as 2, 282kg/ha 69, 900kg/ha and 6, 392kg/ha, respectively, but no significant difference among treatment(P>0.05). 6. In inorganic contents of alfalfas, there was not show same tendency in accordance with treatments. As a results mentioned above, it was possible to use 200kg $P_2O_5/ha$ of fermented cow or poultry manure with sawdust instead of inorganic phosphae fertilizer.

  • Dietary levels of fermented poultry manure(FPM) 0%, 5%, 10% and 20% were included in experimental diets. It is to examine the effects of diets containing different levels of FPM on the performance of broiler chicks, including the nutrient availabilities, compared with that of the commercial diet. In order to evaluate the nutritive value of FPM, feeding and metabolism trials were conducted with a total of 160 broiler chicks for a period of 4 weeks. Contents of CP, crude fat, crude ash, crude fiber and NFE of FPM were 19.43, 2.43, 15.44, 16.57 and 38.31 %, respectively. Although there were no statistical difference in the body weight gain among treatments, weight gain achieved by the group fed diets of 5% substitution of FPM was slightly better than others. The amount of feed intake was significantly higher for FPM included groups than for control group, especially in the group fed diets of 10% substitution of FPM. The feed efficiency tended to be better for the control group than the FPM groups. The feed efficiency tended to get worse as the levels of FPM increased. The digestibility of DM, CP and NFE tended to be similar among treatments, especially it was lower for the group fed diets of 20% substitution of FPM compared with that of another groups. In conclusion, up to 10% substitution of FPM to the diet can be utilized effectively as a broiler feed ingredient, without adversely affecting growth performance.

  • Objectives: An on-site study was conducted in order to quantify indoor exposure levels and the emission rate of particulate matter for domestic poultry buildings. Materials and methods: Three types of poultry building (caged layer house, broiler house, and layer house with manure belt) as classified by mode of manure treatment and ventilation were investigated in this study. Nine sites per each poultry building were selected and visited for measuring exposure levels and emission rate of particulate matter. Total dust and respirable dust among the particulate matter were analyzed based on the weight method. Emission rates were estimated by dividing emission amount, which was calculated through multiplying indoor concentration ($mg/m^3$), by the ventilation rate ($m^3/h$), into indoor area ($m^2$) and number of poultry reared in the poultry building. Results: Mean exposure levels for total dust and respirable dust in the poultry buildings were $3.91({\pm}1.99)mg/m^3$ and $1.99({\pm}0.89)mg/m^3$, respectively. The emission rates of particulate matter in the poultry buildings were estimated as $4.75({\pm}1.22)mg\;head^{-1}h^{-1}$ and $64.39({\pm}24.95)g\;m^{-2}h^{-1}$ for total dust and $0.58({\pm}0.23)mg\;head^{-1}h^{-1}$ and $7.52({\pm}2.51)mg\;m^{-2}h^{-1}$ for respirable dust, respectively. The distribution patterns for total dust and respirable dust were similar regardless of poultry building type. Among poultry buildings, broiler house showed the highest exposure level and emission rate of total dust and respirable dust, followed by layer house with manure belt and caged layer house. Conclusions: The finding that the broiler house showed the highest exposure level and emission rate of particulate matter can be attributed to sawdust utilized as bedding material, which can be dispersed into the air by movements of the chickens. Thus, a work environmental management solution for optimally reducing dust concentrations is necessary for broiler houses.

  • BACKGROUND: Concerns have been raised about the impact of recent high concentrations of fine dust on human health. Ammonia(NH3) reacts with sulfur oxides and nitrogen compounds in the atmosphere to form ultrafine ammonium sulfate and ammonium nitrate (PM2.5). There is a growing need for accurate estimates of the amount of ammonia emitted during agricultural production. Therefore, in this study, ammonia emissions generated from the cultivation of leafy perilla in plastic houses were determined. METHODS AND RESULTS: Cow manure compost, swine manure compost, and poultry manure compost each at 34.6 ton ha-1, the amount commonly used by farmers in the field, was sprayed on the soil surface. Just after spraying cow manure compost, swine manure compost, and poultry manure compost, the ammonia was periodically measured and analyzed to be 22.5 kg ha-1, 22.8 kg ha-1, and 85.2 kg ha-1, respectively. The emission factors were estimated at 70.0 kg-NH3 ton-N, 62.8 kg-NH3 ton-N, and 234.1 kg-NH3 ton-N, respectively. Most ammonia was released in the two weeks after application of the compost and then the amount released gradually decreased. CONCLUSION: Therefore, it is necessary to improve the emission factor through a study on the estimation of ammonia emission by type of livestock manure and major farming types such as rice fields and uplands, and to update data on the production, distribution, and sales of livestock manure.

  • This study was carried out to survey the distribution of farm-yard manure by analysis 355 samples collected from major flue-cured and burley tobacco area. The applied manure amount for flue-cured and burley tobacco were 1,500 kg and 1,600 - 2,000 kg per l0a, respectively. The major raw materials of farm-yard manure were cattle dung, chaff, and rice straw. The main manure used for tobacco plant were cattle dung+chaff, cattle dung+rice straw+chaff, cattle dung+rice straw, and poultry dung+chaff, which were mostly unfinished fermentation materials. The chemical characteristics of farm-yard manure were as follows: pH for 87% of samples was higher than 7.1, total nitrogen for 70% of samples was 0.51-1.50%, P$_2$O$_{5}$ for 48% of samples was higher than 1 %, $K_2$O and CaO were 1-2%, MgO was 0.5-1.0%, and Cl was lower than 0.5% level. In general, the manure used for tobacco cultivation was higher contents of chemical components than that of manure made by rice straw. Also, the concentration of chemical compounds in the samples collected from burley tobacco area were higher than that of flue-cured tobacco districts.s.

  • Disposing technique for dairy cattle manure using earthworms and the possibility of utilizing earthworms in poultry feed were investigated. In addition, chemical properties of manure and cast of earthworms were investigated. Temperature in the vinyl-house for earthworm nursery was able to be maintained above 0$\^{C}$ in winter and 25-28$\^{C}$ in summer. In closed-covering method, the number of escaped earthworms was the highest among three covering methods. The time was longer after manure excretion, the numbers of escaped earthworm were higher. There were some incidences of mortality of earthworm in closed-covering site. The amount of manure ingested by earthworm was increased in order of non-covering, closed-covering and gap-covering method. Fresh manure was more ingested than old one by earthworm. Earthworms reduced manure about 50% on the dry weight base and reduced total amounts of N, P$_2$O$\_$5/ and K$_2$O of manure by 41, 50 and 60%, respectively. Earthworm could be utilized by adult poultry (>60 g) for feeding. However, adverse effect of live earthworm was observed with young poultry (<450 g).

  • This work was carried out to measure volatile fatty acids emissions from different manure (poultry, swine, cattle) incubated at $10^{\circ}C$, $25^{\circ}C$, and $37^{\circ}C$ for 6 days under anaerobic condition. Following are summary of these tests results. 1. Amounts of Acetic acid generated were 1,128.05mg/kg, 628.21mg/kg and 592.50mg/kg for swine, poultry, and cattle manure, respectively, during the period of incubation. In the case of swine and cattle manure, 83.87%(946.10mg/kg) and 57.49%(340.63mg/kg) from all the temperature treatments were produced in the $25^{\circ}C$, respectively. 83.57% in swine and 78.79% in cattle manure were intensively emerged from 3 day, 4 day and 5 day of the $25^{\circ}C$ treatment. In the case of poultry manure, 45.36%(284.93mg/kg) and 45.36%(284.93mg/kg) in the $25^{\circ}C$ and in the $37^{\circ}C$, respectively, were produced. Accordingly, acetic acid generated from poultry manure was characteristic of being mainly produced in more than $25^{\circ}C$. 2. Amounts of propionic acid generated were 238.56mg/kg, 162.14mg/kg and 155.49mg/kg for swine, poultry, and cattle manure, respectively, during the period of incubation. In the case of swine manure, 78.52%(187.32mg/kg) of propionate emitted from all the temperature treatments was produced in the $25^{\circ}C$ and 79.1% of them was intensively emerged from 3day, 4day and 5day of the $25^{\circ}C$ treatment. In the case of poultry manure, 35.12%(56.95mg/kg) and 45.89%(74.40mg/kg) of the propionate amounts were produced in the $25^{\circ}C$ and in the $37^{\circ}C$, respectively. In the case of cattle manure, 28.21% (43.86mg/kg) and 49.30% (76.66mg/kg) of the propionate amounts were produced in the $10^{\circ}C$ and in the $25^{\circ}C$, respectively. Accordingly, propionate evolved from poultry manure was characteristic of being mainly produced in more than $25^{\circ}C$ and from cattle manure, in less than $25^{\circ}C$, respectively. 3. Amount of butyric acid generated were 1,463.87mg/kg, 96.72mg/kg and 129.18mg/kg for swine, poultry, and cattle manure, respectively, during the period of incubation. The time intensively emerged from the period of incubation was differently generated from the incubation temperature and animal feces. 4. Amounts of iso-valeric acid generated were 6,885.99mg/kg, 399.28mg/kg and 307.47mg/kg for swine, cattle and poultry manure, respectively, during the period of incubation. In the case of swine and cattle manure, 28.22%(1,943.52mg/kg) and 48.56%(193.90mg/kg) in the $25^{\circ}C$, 68.76%(4,734.90mg/kg) and 46.93%(187.40mg/kg) in the $37^{\circ}C$, respectively, were occupied. Accordingly, iso-valeric acid evolved from swine and cattle manure was characteristic of being mainly produced in more than $25^{\circ}C$. In the case of poultry manure, 59.89%(184.13mg/kg) of iso-valeric acid generated from all the temperature treatments was produced in the $37^{\circ}C$ and 100% of them was intensively emerged from 2 day and 3 day of the $37^{\circ}C$ treatment.

  • An experiment was conducted to study the performance and carcass characteristics of Hanwoo steers fed whole crop corn silage ensiled with poultry manure (PM) for 18 months. The experiment was designed as a randomized block design with three phases. Steers were allotted in one of three dietary treatments, which were ammonia-treated rice straw (AS), whole crop corn silage (CS) and whole crop corn+30% PM silage (based on DM; MS). All diets were supplemented with concentrate. Total body weight gain and average daily gain (ADG) in MS group were increased (p<0.05) by 6% over AS group. The MS treatment enhanced (p<0.05) total and daily intakes of forage compared with the AS and CS treatments while there was compensatory effect on concentrate intake by AS group. Carcass characteristics were improved by feeding MS. MS increased (p<0.05) carcass weight and marbling score (7.5 and 22.5% of AS, respectively), and reduced (p<0.05) backfat thickness (13.2 of AS and 16.6% CS). Carcass grade and meat quality grade were also improved by MS compared with AS and CS. Under the conditions of this study, MS was an efficacious replacement for corn silage for steers.

  • Laboratory experiments of poultry manure incubated for three days at $35^{\circ}$ were conducted to learn some informations on the relief of nitrogen loss during processing. Results obtained are as follows: 1) Blending phosphoric acid, triplesuperphosphate or superphosphate to poultry manure could reduce the volatilization of ammonia and saved nitrogen in the manure by 80 to 90 percent, though nonblending saved the nitrogen only by 40 to 60 percent during three days incubation. 2) The additives must be blended thoroughly to the manure to obtain the least loss of nitrogen during the incubation. 3) The severe loss of nitrogen was occurred from the drying process of fermented manure of both treatment, that is $60{\sim}80$ percent loss at the blended treatment with phosphoric acid, triplesuperphosphate or superphosphate, and $70{\sim}90$ percent loss at non-blended. 4) Drying the fermented manure under the fixed temperature of about $65^{\circ}$ for three days saved more nitrogen than dried manure under the temperature gradually raised from the room temperature to about $45{\sim}65^{\circ}$ for three days.
