          지렁이 분말의 급여가 강제환우시킨 산란노계의 생산성에 미치는 영향

          손장호 한국유기농업학회 2004 韓國有機農業學會誌 Vol.12 No.2

          A study was conducted to investigate the effect of supplementing earthworm meal (EWM) on the performance of spent laying hens after induced molting, and fatty acid composition in egg yolks. A total of 90 laying hens at 73 weeks of age were fed the experimental diets containing 0.0% (Control) and 0.2% of EWM for 4 weeks. Eggs were collected and weighted every day and egg production and feed conversion were recorded every week during the experimental period. However fatty acid composition of egg yolk were measured at last week of experimental period. An amount of feed intake increased by supplemental with EMW except for first week experimental period (P<0.05). When 76 and 77 week of age, egg production and daily egg mass were improved by the supplemented with EWM (P<0.01), but average egg weight was not different when fed a EWM, therefore feed/egg mass was significantly decreased when fed a EWM. The ratio of egg yolk n-6/n-3 fatty acids contents was significantly improved fed a EMW (P<0.05). It is concluded that supplementing 0.2% of earthworm meal in the spent laying hens after induced molting was fast in recover of physical strength, therefore improves laying performance.

          닭에 있어서의 caecostomy (맹장으로 튜브를 삽입하는) 기술

          손장호 한국생명과학회 2004 생명과학회지 Vol.14 No.4

          A caecostomy technique (surgery for inserting tube into caeca) was developed to quantify urine backflow into the caeca. Two days post-surgery, caecostomised chickens were flushed with 20 ml of warm saline solution every other day for 10 days. After surgery birds temporarily lost appetite and activity, but they were restored gradually in a few days. The incision healed within 10 days post- surgery. Excreta were collected daily from caecal tubing and cloaca by surgical attachment of polyethylene collection vessels to the chickens. Post-mortem examinations ascertained that the caeca were intact around the Latex tubing. 닭 맹장으로의 尿의 역류량을 측정하기 위해서 Caecostomy (맹장으로 튜브를 삽입하는 수술)기술이 개발되었다. 시술 이틀 뒤부터 맹장에 튜브가 장착된 닭은 20ml의 따뜻한 생리적 식염수를 이용하여 격일간격으로 10일 동안 맹장에 장착된 튜브를 환류시켰다. 시술후 닭은 일시적으로 식욕과 활기가 감퇴되었지만, 몇일내에 정상으로 회복되었다. 수술로 인해 생긴 상처는 시술 10일내에 아물었다. 맹장에 장착된 튜브와 총배설강에 외과적으로 시술된 프라스틱 채집병을 이용하여서 배설물이 매일 모아졌다. 사후검사에서 맹장에 삽입되었던 고무튜브주위를 둘려싸고 있는 완벽한 맹장이 확인되었다.

          The purpose of this study was to evaluate the effect of dietary ceramic powder on laying performance, Pathogenic bacterial (E. coli, salmonella) counts in caecal contents and excreta, malodorous substances (NH3, H2S, VFA) in excreta and fatty acid composition of egg yolk in laying hens. Three hundred sixty layers at 34 weeks of age were divided into three groups of 120 hens each and each group was fed diets containing 0 (control), 0.4, or 0.8 ceramic powder for six weeks.It is concluded that 0.4% ceramic powder supplementation of diets decreased of E coli, salmonella counts in the intestine and emission of NH3 and VFA gas from excreta, and improved the laying performance and ratio of egg yolk fatty acids contents. 본 연구는 Ceramic 분말의 첨가가 산란계의 생산성, 맹장 및 배설물중 병원성 미생물(E. coli, salmolella)의 수, 배설물중의 악취물질(NH3, H2S, VFA) 및 난황중 지방산 조성에 미치는 영향을 구명하기 위해서 실시하였다. 총 360수의 34주령의 산란계를 120 마리씩 3처리구로 구분하여서 Ceramic 분말 0.0%(대조구), 0.4% 및 0.8%를 첨가한 사료로 6주 동안의 사양시험을 실시하였다 결론적으로 34에서 40주령의 산란계 사료에 0.4%의 Ceramics 분말의 첨가는 생산성 향상, 장관내 E. coli 및 Salmonella 수가 감소되어 배설물 중의 NH3 및 VFA의 발생량 감소 및 난황중의 지방산 조성을 개선시킬 가능성이 인정되었다.

        • 저(低)단백질사료와 요소의 급여시, 맹장결찰 수술된 닭에 있어서 [15N]urea의 이용성에 관한 연구

          손장호,Karsawa Yutaka 한국가금학회 2010 한국가금학회 정기총회 및 학술발표회 Vol.27 No.-

          The effect of cecal ligation on the utilization of dietary [15N]urea in chickens fed a low protein diet plus urea were investigated. Nitrogen balance and utilization tended to increase by cecal ligation. Total uric acid excretion was significantly decrease by cecal ligation in chickens from origin of diet and urea (P<0.01). when low protein diet with urea, 31.6% of dietary urea utilized in cecal ligated chicken (72.9% of dietary urea utilized in control chicken, P<0.01). Excretion of ammonia was increase and decrease from origin of diet (P<0.01) and urea (P<0.01), respectively. This indicates that ceca of chickens fed protein-deficient diets, ceca is beneficial role for urea nitrogen utilization, but ceca do not always positive role for nitrogen utilization synthetically.

          Rosemary의 급여가 육계의 생산성, 맹장내 균총 및 깔짚 중 유해가스 발생량에 미치는 영향

          손장호 한국유기농업학회 2015 韓國有機農業學會誌 Vol.23 No.2

          본 연구는 육계 생산과정에서의 건조 Rosemary 잎 분말의 급여가 육계의 생산성, 맹장내 균총 및 깔짚 중 유해가스 발생량에 미치는 영향에 대해서 조사하였다. 총 216수의 7일령 육계에 대조구, Rosemary 분말 0.5% (5 g/kg diet, T1) 및 1.0% (10 g/kg diet, T2)로 구분하여 35일령까지 총 4주간의 사양 시험을 실시하였다. 사육기간중 증체중 및 사료효율은 Rosemary 급여에 의해서 유의하게 증가하였지만(P<0.05), 처리구간(T1 Vs. T2)에는 유의한 차이가 인정되지 않았다. 사료섭취량 및 도태율은 대조구와 처리구간에 차이는 인정되지 않았다. 21일령과 35일령 모두 맹장내 Lactobacillus의 수는 Rosemary 급여에 의해서 유의하게 증가하였고(P<0.05), E. Coli 및 Salmonella의 수는 유의하게 감소하였다(P<0.05). 혐기성 총 미생물 수는 Rosemary의 첨가에 의한 영향은 인정되지 않았다. 깔짚 내 Ammonia의 발생량은 Rosemary 첨가에 의해서 유의하게 감소하였다(P<0.05). 그러나 처리구간(T1 Vs. T2)에는 차이가 인정되지 않았다. 이상의 결과를 종합해보면, 육계사양에서 건조 Rosemary 잎의 급여는 사료중 영양소 이용율 증가, 소화관내 유익균의 증가 및 유해균의 감소, 및 배설물 중 NH3의 발생량 감소로 인한 증체량 및 사료효율을 개선시킬 가능성이 생각된다. The objective of this study was to evaluate the effect of dietary rosemary on performance, microflora population in cecum and noxious gas emission from litter of broiler. A total of 216 broiler chicks at 7 days old were fed the commercial diet (control), added 0.5% level of dried rosemary leaves (5 g/kg diet, T1) and 1.0% level of dried rosemary leaves (10 g/kg diet, T2) for 4 weeks. The body weight gain and feed conversion ratio were improved by feeding rosemary at 7 to 35 days of age (P<0.05), but there was no difference between T1 and T2. Amount of feed intake and mortality were not different among the three group. There was an increase in the microflora population of Lactobacillus (P<0.05) and decreased in E. coli and salmonella (P<0.05) in the cecum contents at 21 and 35 days of age. Emission of ammonia gas from litter was significantly decreased by supplementary rosemary at 21 to 35 days of age (P<0.05), but there was no difference between T1 and T2. These results indicated that feeding 0.5 to 1.0% level of dried rosemary leaves during broiler production improved in the body weight gain and feed conversion ratio because of increasing nutrient digestibility from feed, also increase in intestinal beneficial bacteria and decrease in harmful bacteria in the cecum contents, and decreasing emission of ammonia gas from litter.
