Characteristics of Ash (Coal, Wood and Rice Hull) and Its Potential Use as an Additive in Poultry Manure for Protecting the Environment

남기홍,Nahm K.H. The Korean Society of Poultry Science 2006 韓國家禽學會誌 Vol.33 No.1

Ash amendment to manure holds potential as a method to neutralize manure for reducing odor and reduce phosphorus (P) solubility in runoff from fields where manure has been applied. This review focuses on the literature published about ash characteristics and their environmental uses. There is no uniform physico-chemical definition of the selected ashes (coal fly ash-CFA, wood ash-WA, and rice hull ash-RHA) used in various studies. These ashes vary greatly in their acidity (pH<6.0) or alkalinity (pH>12.5) based on the conditions at which they were farmed and the composition of the ash source. CFA amendment to manure reduced manure-P solubility and application of CFA amended manure to agricultural soils is a method to improve water quality WA may prove to be a valuable manure odor control amendment since WA contains a high level of carbon. A major biomass source is rice hull (husk) which provides an ash source (RHA). The .ice hull and RHA are sources of silica, compromising about 20% and 60%, respectively. So far research has been directed at the use of CFA, WA and RHA as soil amendments, but there is potential use of these materials as manure additives to sequester P and reduce odors. 재는 가축분을 중성화 시키며 토양에 산포하면 악취를 저감시키는 역할을 하며 하천에서 P의 양을 감소시킬 수 있다. 그러므로 본 연구에서는 재의 특성과 이들의 첨가가 가져올 환경적인 이용에 관해서 언급하였다. 재는 아직도 물리적 화학적으로 일정한 정의가 없다 (석탄재-CFA, 목재재-WA, 왕겨재-RHA). 이들 재를 형성하고 있는 조건과 조성에 따라 산도는 6.0이하 그리고 12.5이상까지 이른다. CFA를 분중에 첨가하면 분중에 녹아있는 P의 양이 감소되어 토양에 산포하면 수질을 향상시킨다. WA는 WA 자체에 많은 탄소 원자를 갖고 있기 때문에 분에서 발생하는 냄새를 제거할 수 있다. RHA는 재중에 $20{\sim}60%$ 가량이 실리카이다. 현재까지 CFA, WA 그리고 RHA를 토양에 산포하여 미치는 영향에 대한 연구는 많이 되어 있으므로 앞으로 가축분에 첨가하면 분중의 P과 악취를 낮출 수 있는 연구가 필요하다.

Comparison of the Chicken Large Intestine to the Large Intestine of Pigs and the Rumen of Cows

남기홍,Nahm K.H. The Korean Society of Poultry Science 2006 韓國家禽學會誌 Vol.33 No.1

닭의 대장은 해부학적, 생리학적으로 돼지의 대장이나 소의 men과 다르다. 닭의 대장은 소의 men이나 돼지의 대장에 비교하여 잘 발달되어 있지 않다. 그러나 닭의 대장속에 있는 미생물군은 rumen 속의 것과 비슷하다. 특히 닭의 맹장속에는 많은 미생물이 있으며 이 미생물군은 나이, 사료, 성성숙의 정도, 항생제 사용 유무 등에 따라서 다양하게 나타난다. 단백질은 장내의 미생물 형성에 중요한 영양소이다. 닭에서 소장의 길이는 전장 길이의 65%를 차지하며 닭의 맹장은 8.1 %그리고 직장과 공장은 4.6 %를 차지한다. 소장 내에 분포하는 미생물 군은 현재까지 약 10%가 구명된 상태로서 나머지 90%에 대한 정보는 전무하다. 최근의 연구에 따르면 에너지, 저급지방산 (VFA)과 그리고 전해물질이 대장에서 약간씩 흡수되는 것으로 알려져 있다. 닭의 소장은 각종 효소등이 분비되어 소화가 일어나는 중추적인 역할을 하는 것으로 알려져 있다. 앞으로도 많은 연구가 과당류 즉 sucrose thermal oligosaccharide caramel (STOP), fructooligosaccharides (FOS), mannanoligosaccharide (MOS), galactooligosaccharide (GOS) 그리고 isomaltooligosaccharides (IMO)등이 맹장과 대장내에서 어떻게 소화가 일어나는지에 관해서 집중되어야 한다. 과량의 섬유질 함량은 닭의 소화에 치명적일 수 있지만 적당량을 사료에 혼합하여 급여하면 소장의 길이와 함량을 증가시킬 수 있는 효과가 있다. The large intestine of the chicken differs both anatomically and physiologically from the pig's large intestine and the men of the cow. The chicken's large intestine is less developed than the pig's large intestine or the cow's lumen. This paper summaries these differences. The chicken's large intestine contains a microbiological population similar to that found in the rumen. The chicken's caeca especially contains a large number of microorganisms, but this population varies according to age, fred, maturity, antibiotic use and etc.. Protein is an essential nutrient for the formation of intestinal microvilli. A study showed that the length of the small intestine was 63 % of the total gastrointestinal tract (GIT) length, while caecum was 8.1 %, and the colon and rectum were 4.6 %. The establishment of the microbial population of the small intestine occurs earlier than that of the caeca, but the identity of approximately 90 % of microbial population of the chicken GIT is hon. Recent studies have shown that energy, volatile fatty acid (VFA) and electrolytes that are found in the large intestine may be absorbed to a certain degree. The chicken small intestine is the primary location for digestion with a variety of enzymes being secreted here. Much research is being conducted into the digestion of sucrose thermal oligosaccharide caramel (STOP), fructooligosaccharides (FOS), mannanoligosaccharide (MOS), galactooligosaccharides (GOS) and isomalto-oligosaccharides (IMO) in the chicken caeca and large intestine. Excessive fibre content in the feed has detrimental effects, but proper fibre supplementation to chicken diets can improve the length and capacity of the small intestine.

Selenium-based photosensitive films doped arsenic and tellurium were prepared by means of vacuum evapora arsenic was used to prevent crystallization of the amorphous selenium. Tellurium was used to increase sensitivity of the film. The thermal stability of Se + As monolayer was increased up to 110 ℃ when it contai 10 wt.% of arsenic, and its photocurrent with 10 V about 0.7 μA under 10 lux illumination and the photosensit about 1. The spectral response of Se + As + Te (50 : 10 : 40) ternary film showed the enhanced red sensitivity optical absorption edge and the optical band gap were 750 nm and 1.6 eV, respectively. The photocurrent with of the ternary film was about 1.1 μA under 10Iux illumination and the photosensitivity was about 1.

Amorphous selenium thin films have been prepared by means of thermal vacuum evaporation. Generally, it is known that selenium films have two major shortcomings, i.e., thermal instability due to crystallization and low sensitivity to red light. The dependence of their electrical and optical properties on doping ratio of Te & As, annealing and film structure are described. The selenium film doped with 5wt.% of arsenic has 1.89eV optical bandgap, unity photosensitivity〈γ=△ln(Amp)/△ln(Lux) and 10 Ω.㎝ dark resistivity. The film doped with 40 wt.% of tellurium and 5 wt.% of arsenic has 1.6eV optical bandgap, unity photosensitivity and 10 Ω.㎝ dark resistivity. In other to get high photocurrent to dark current ratio(SN ratio). multilayer〈Se-As(3000A??)/Se-As-Te(9000A??)/Sb₂S₃(1000A??)〉films have been fabricated. The multilayer with 5V bias showed 1.04 photosensitivity and 70dB SN ratio under 100 lux illumination. The dynamic characteristics of the films was measured the condition of 1KHz frequency, 5V b-ias an 100 lux illumination. The multilayer showed 100nA output current, 0.3 msec photoresponse time and good homogeneity.

This study was conducted to investigate the incubation length and the weight loss with 119 ostrich eggs which were imported from the U.S. in two groups of 54 Ostrich eggs(first batch) on February 8, 1998 and 65 eggs(second batch) on June 7. 1998. The imported eggs were allowed to place quietly for 12 hours to be incubated in the 4 incubators (48 eggs capacity per one incubator and 2 incubators per each batch) which were set at a controlled temperature (36.6℃±0.2) and the relative humidity(25-30%) 3 days prior to setting the eggs. The average egg weight just before starting incubation was significantly (P$lt;0.05) heavier in 1st batch eggs than in 2nd batch eggs. The weight loss of fertile eggs during 40-day incubation length was 13.20% in 1st batch eggs and 14.26% in the 2nd batch of eggs. The weight loss during incubation period was significantly (P$lt; 0.01) higher in the hatched eggs than in the unhatched eggs and the longer storage period after laying prior to incubation resulted in significantly (P$lt;0.05) more unhatched eggs. The average incubation length was 44 days in the first batch eggs and 45 days in the second batch eggs. The results of this study indicated that the average weight loss of fertile eggs during 40-day incubation length was 13-14% and the average incubation length was 44-45 days.
