The present study was conducted to determine the optimal supplementation level of beta-mannanase in the diet of laying hens. A total of 320 Hy-Line Brown layers (80 weeks of age) were assigned randomly into four groups on the basis of laying performance. Each treatment had eight replicates with 10 birds each (80 birds per treatment). Two hens were caged individually. Treatments were basal diet supplemented with 0 (control), 0.04, 0.08, and 0.16% beta-mannanase during the nine-week feeding period. Laying hens fed diets supplemented with increasing levels of beta-mannanase had increased (linear, p<0.05) overall egg production and egg mass. In addition, these hens had greater retention of dry matter, crude protein, gross energy, calcium, and mannan (linear, p<0.05). Dietary beta-mannanase treatments had no effect on blood metabolites such as total carbohydrate, triglycerides, glucose, total protein, and blood urea nitrogen, or excreted ammonia nitrogen and volatile fatty acids. The results obtained in present study indicate that dietary supplementation of beta-mannanase has the potential for improving the performance of laying hens. The optimal supplementation level is 0.04% beta-mannanase in the diet.

The main information for a marine navigation is ship's bearing obtained from Gyro, Gyrocompass, Magneticcompass and electronic navigation systems such as LORAN, OMEGA and GPS. However, some of these systems have a disadvantage or restricted conditon involved critical problems in a war-ship and weapon system. In the work, we have done the basic resrarch, analysis of error pattern for GPS, for the development of the ship's seondary bearing sensor (GPS-Compass) to provide the back-up system of Gyro/Gyrocompass and a substitution way of Magneticcompass.

An experiment was conducted to investigate the effect of microbial phytase Natuphos^(ⓡ) supplementation, individually and in combination with carbohydrase enzyme complex (composed of enzymes targeted to SBM dietary components such as α-galactosides and galactomannans; ENDO-POWER^(ⓡ)) to corn-soy basis diet with low nutrient levels on growth performance and nutrient digestibility of growing pigs. A total of 48 crossbred four dietary treatments, based on weight and age, according to Randomized Complete Block Design. There were three pens per treatments and 4 pigs per pen. the dietary treatments were 1) CON (control diet with 3,380㎉/㎏ of metabolizable energy, 18.96% of crude protein, 1.10% of lysine, 0.75% of calcium and 0.35% of available phosphorus), 2) LP+NTPS (CON diet with 0.15% unit lower available P levels + 0.1% phytase (500 Ftu/㎏; Natuphos^(ⓡ)), 3) LEL+ENP (CON diet with 3.0% unit lower ME and lysine levels+0.1% carbohydrase enzyme complex (ENDO-POWER^ⓡ)), and 4) LPEL+ENZ (CON diet with 0.15% unit lower available P levels and 3.0% unit lower ME and lysine levels+0.1% ENDO-POWER^(ⓡ) and 0.1% Natuphos^(ⓡ) (500 FTU/㎏). There was no significnat difference (p>0.05) in average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) among dietary treatments during the whole experimental period (0 to 4 weeks). Apparent digesibility of gross energy was greater in LP+NTPS and LPEL+ENZ groups than in the LEL+ENP (p<0.05). Apparent digestibioity of phosphorus was greater in LP+NTPS than in LEL+ENP (p<0.05). Dry matter excretion was lowest in LPEL+ENZ and phosphorus excretion was lowest in LP+NTPS (p<0.05). Overall, pigs fed on LPEL+ENZ group tended to have better nutrient digestibility (dry matter, gross energy, crude protein and phosphorus) than pigs fed on control group. All dietary enzyme treatment groups showed lower feed cost/body weight gain of pigs than control group. In conclusion, the results from the present study suggest that the simultaneous inclusion of phytase and carbohydrase enzyme complex to diets is advantageous with respect to reducing nutrient excretion of growing pigs and may contribute to increased economic return when added to com-soy based growing pig diets.
에너지 수준이 다른 사료에 복합효소제의 첨가가 육계의 사양성적, 영양소 소화율, 혈액성상, 장내미생물 균총 및 소장 융모에 미치는 영향

The present study was conducted to investigate the effects on growth performance, nutrient digestibility, and gut health of broiler chickens when a dietary supplementation of multienzymes was added to diets, containing different energy levels. A total of 480 broiler chickens of similar body weight (Ross 308, 1-day-old) were randomly subjected to four treatments. The dietary treatments included a corn-soybean meal-based diet supplemented with: multienzyme (amylase+protease+ mannanase+xylanase+phytase), 0.05% enzyme, and different energy levels (3010 and 3060 kcal/kg). The experimental diets were fed to the chicks in a mash form for 35 days in two phases (1–21 d, phase I; and 22–35 d, phase II). During the overall period, chicks fed with diets supplemented with multienzymes had a better weight gain (p<0.05) and feed conversion ratio (FCR) than those fed with diets without enzymes. There was no difference in the growth rate and FCR among the chicks fed with diets supplemented with enzymes, even though the dietary energy levels were different. The apparent fecal and ileal digestibility of dry matter, gross, crude protein, calcium, and phosphorus were significantly enhanced (p<0.05). The population of cecal and ileal Lactobacillus spp. was significantly increased (p<0.05), and Clostridium spp. and coliforms were significantly decreased (p<0.05) in diets supplemented with enzymes. Villus height and villus height to crypt depth ratio in the small intestine was also significantly enhanced (p<0.05) in diets supplemented with enzymes. In conclusion, multienzyme supplementation had positive effects on the weight gain of broilers, FCR, digestibility of nutrients, and on the growth of intestinal microbiota.

가축분뇨는 고농도의 유기오염물질을 포함하고 있어 처리가 용이하지 않은 농업부산물 중의 하나이다. 현재는 대부분 호기 또는 혐기소화 방식을 이용하고 있으며, 약 89% 이상 퇴· 액비화로 자원화하고 있는 실정이다. 본 연구는 가축분뇨를 이용한 새로운 자원화 방안으로 직접 전기에너지를 생산할 수 있는 미생물연료전지를 이용하여 가축분뇨로부터 전기발생과 유기오염물질 제거능을 알아보았다. 본 연구에서 사용한 미생물연료전지 산화전극과 환원전극으로 스테인리스 스틸 망을 사용하였고, 폴리에스터 천을 분리막으로 이용하였다. 외부 저항은 50 ohm을 연결하여 운전하였다. 미생물연료전지는 4개의 단위 셀이 순차적 흐름방식으로 운전되는 시스템으로, 가축분뇨가 4개의 단위 셀 중 첫 번째 단위 셀에 유입되고, 첫 번째 단위 셀의 유출수는 두 번째 단위 셀에 유입되고, 두 번 단위 셀의 유출수는 세 번째 단위 셀로 유입되어 최종적으로 네 개의 단위 셀을 거쳐 유출되는 시스템으로 운전하였다. 이렇게 4개의 단위 셀을 연속 공정으로 운전하였을 때 약 170일 동안 전극이나 분리막의 교체 없이 운전이 가능하였다. 각 단위 셀의 유출수를 이용하여 각 단위 셀에서의 용존성 화학적 산소 요구량(SCOD)의 제거량은 743.5, 524.8, 349.9, 그리고 1,137.1 mg/L · d 이었다. 체류시간은 약 13.7h이었으며, 유기오염물질의 처리 효율은 약 18.2% 정도였다. 일반적인 호기 또는 혐기발효를 위한 체류시간은 20~40일 이상으로 이에 비하여 매우 짧은 체류시간으로 처리효율이 낮은 것으로 나타났다. 이때 전류는 각 단위 셀에서 각각 4.9±0.2, 4.8±0.0, 4.1±0.1, 그리고 4.2±0.2 mA가 발생되었다.
