Description

이산화염소수를 이용한 계사 깔짚의 살균소독 방법{Sterilization method of chicken cage litter using aqueous chlorine dioxide}Sterilization method of cage litter using chlorine dioxide water {Sterilization method of chicken cage litter using aqueous chlorine dioxide}

본 발명은 살균소독제로써 이산화염소수를 계사 내 깔짚에 처리하는 것으로, 보다 상세하게는 살균효과가 우수하면서도 유해성이 없는 새로운 깔짚 살균소독제 개발 및 그 적용 방법에 관한 것이다.The present invention is to treat chlorine dioxide water as a disinfectant to the litter in cages, and more particularly, to develop a new litter disinfectant disinfectant with excellent disinfection effect and no harmful.

계사 내 깔짚은 닭의 주된 생활환경으로 닭에서 배출되는 배설물 등에 의한 미생물학적 위해요소가 항상 존재한다. 닭은 계사 내에서 짧게는 3주, 길게는 5주 동안 성장하므로 깔짚의 위생은 도계 후 닭의 품질 등에 많은 영향을 끼친다. 계사 내 깔짚으로 톱밥, 왕겨, 볏짚 등이 일반적으로 사용되며 이들을 5 cm 이상 깔아주는 것이 일반적이다. 깔짚은 계사 바닥의 오염을 방지하고 계분과 사육 시에 발생하는 수분을 흡수하여 건조하게 유지하는데 필요하며, 닭이 활동하는 생활의 장소로서의 역할을 감당한다. 특히 육계 사육시 깔짚은 계사 환경조성에 많은 영향을 끼쳐 육계의 생산성과 상호관련이 높다. 또한 깔짚 가격 상승으로 육계 생산비 증가의 원인이 되기에 적절한 깔짚재의 재활용이 필요한 실정이다. 따라서 현재 대부분의 계사에서는 사용된 깔짚을 재사용하는데 이때 깔짚 윗층을 제거하고 최초 깔짚량의 1/2~1/3정도를 추가하여 사용하는데 이때 계사 환경 관리를 잘 수행하여 닭의 질병예방에 주의하여야 한다. 현재 계사 내 바닥에 사용하는 소독제로는 페놀계, 암모니아, 산소계, 알데히드 화합물 등을 사용하는데 통상적으로 무처리 대조구에 비해 호기성 균수를 유의적으로 감소시키지 못한다. 계사 소독은 통상 깔짚 반입 전에 2-3차례에 걸쳐 소독제에 의한 분무소독이 이루어지고 깔짚과 기구가 반입한 후에는 계사 밀폐 후 포르말린 케익이나 포르말린 용액으로 훈증 소독을 한다. 그러나 기존 소독 방법에 의해 이루어진 깔짚의 경우, 병원성 미생물이 사멸되지 않는 환경을 제공하여 미생물에 의한 창상 등 피부병 등이 빈번하게 발생한다. 현재 계사에서 사용되는 깔짚은 일반 소독제를 이용하여 살균을 하고 재사용 시 그 위에 적당량의 새 깔짚을 첨가하는데, 대부분의 양계 농가에서 사용하는 기존 소독제에 의해 살균소독 된 깔짚의 미생물 오염도 평가 결과, 깔짚의 병원성 미생물의 잔존 등 미생물학적으로 안전하지 못하였다. 특히, 깔짚은 육계의 창상발생 등 병원성 미생물 오염의 중요한 매개체가 되므로, 부절하게 살균 소독된 깔짚은 육계의 피부병 증가 등 계사 환경에 바람직하지 못한 결과를 초래한다. 그러므로 계사에서 사용되는 깔짚의 미생물학적 안전성 확보를 위한 새로운 살균소독제의 개발이 필요하다.The litter in the cage is the main living environment of the chicken, and there is always a microbiological hazard caused by the excreta discharged from the chicken. Chickens grow for as little as 3 weeks and as long as 5 weeks in the cages, so the hygiene of the litter affects the quality of the chickens after the slaughter. Sawdust, rice husk, rice straw, etc. are commonly used as cage litter, and they are generally laid over 5 cm. The litter is necessary to prevent contamination of the bottom of the house, to absorb moisture generated during poultry and breeding, and to keep it dry, and to serve as a place of livelihood of chickens. Especially, in raising broilers, litter has a great influence on the environment of the poultry and is highly correlated with the productivity of broilers. In addition, it is necessary to recycle suitable litter material to increase the production cost of broilers due to rising litter prices. Therefore, most of the cages currently use the litter, but the upper layer of litter is removed and 1/2 to 1/3 of the original litter is added. do. Phenolic, ammonia, oxygen, aldehyde compounds and the like are currently used as a disinfectant for floors in cages, and generally do not significantly reduce aerobic bacteria in comparison with untreated controls. The sterilization of cages is usually carried out two or three times by disinfectant spraying before littering. After the litter and utensils are brought in, the cages are closed and fumigated with formalin cake or formalin solution. However, in the case of the litter made by the existing disinfection method, by providing an environment in which pathogenic microorganisms are not killed, skin diseases such as wounds caused by microorganisms frequently occur. The litter used in the current housing system is sterilized using a general disinfectant, and when reused, an appropriate amount of new litter is added to it.As a result of evaluation of microbial contamination of litter sterilized by existing disinfectants used in most poultry farms, It was not microbiologically safe, such as the presence of pathogenic microorganisms. In particular, since litter becomes an important mediator of pathogenic microbial contamination such as broilers in broilers, improperly sterilized litter causes unfavorable effects on the housing environment such as increased skin disease in broilers. Therefore, it is necessary to develop a new disinfectant disinfectant to ensure microbiological safety of litter used in cages.

염산과 아염소산나트륨을 1:1 비율로 섞어 적당량의 증류수를 첨가하여 500 ppm 이산화염소수를 제조하였다 (도 2). 이산화염소수를 깔짚이 충분히 젖을 때까지 분무한 후, 상온 건조하는 과정을 5회 반복하였다.Hydrochloric acid and sodium chlorite were mixed in a 1: 1 ratio to add 500 mL of chlorine dioxide water by adding an appropriate amount of distilled water (FIG. 2). After spraying chlorine dioxide water until the litter is sufficiently wet, the process of drying at room temperature was repeated five times.

각 깔짚 시료 10 g을 취하여 멸균백에 넣고 희석액 9배량의 0.1% 펩톤수를 가한 후 3분 동안 균질화 하였다. 그리고 거즈에 거르고 0.1% 펩톤수로 희석한 후 각각의 선택배지에 분주하였고, 형성된 집락 수를 계수하여 CFU(colony forming unit)로 표기하였다. 일반 세균은 plate count agar 배지를 사용하여 37℃에서 48시간 배양한 후 집락 수를 계수하였고, 효모 및 곰팡이는 potato dextrose agar 배지를 사용하여 37℃에서 72시간 배양한 후 집락 수를 계수하였다. Escherichia coli는 MacConkey agar 배지를 사용하여 37℃에서 24시간 배양한 후 붉은색 집락 수를 계수하였으며, coliform은 PetrifilmTM coliform count plate를 사용하여 37℃에서 24시간 동안 배양한 후 기포가 형성된 붉은색 집락 수를 계수하였다. Listeria는 oxford medium base를 사용하여 37℃에서 48시간 동안 배양 한 후 검은색 환이 형성된 집락 수를 계수하였다. Salmonella는 xylose lysine desoxycholate agar 배지를 사용하여 37℃에서 24시간 배양한 후 검은색 콜로니 수를 계수하였다.10 g of each litter sample was taken and placed in a sterile bag, followed by homogenization for 3 minutes after adding 0.1% peptone water of 9 times the dilution. The gauze was filtered, diluted with 0.1% peptone water, and dispensed into each selective medium. The number of colonies formed was counted and expressed as CFU (colony forming unit). Normal bacteria were incubated at 37 ° C. for 48 hours using plate count agar medium, and colonies were counted. Yeast and mold were counted at 37 ° C. for 72 hours using potato dextrose agar medium. Escherichia coli, MacConkey agar and then using the culture medium were incubated for 24 hours at 37 ℃ was counting the number of red colonies, coliform is Petrifilm TM coliform count plate number of red colonies bubbles are formed after incubation at 37 ℃ for 24 hours using a Was counted. Listeria counted the number of colonies with black rings after incubation at 37 ° C for 48 hours using oxford medium base. Salmonella was incubated for 24 hours at 37 ° C using xylose lysine desoxycholate agar medium to count the number of black colonies.

상기 표 1에서도 확인할 수 있듯이 기존 소독제에 의해 소독된 깔짚의 경우 상당량의 유해미생물이 검출되는 것에 반하여 이산화염소수에 의해 처리된 깔짚의 경우, 기존 소독제에 의해 살균된 깔짚보다 높은 감균 효과를 얻을 수 있었다. 따라서 이산화염소수 처리는 계사 내 깔짚의 미생물학적 안전성을 확보하기에 적합하다.As can be seen in Table 1, in the case of the litter sterilized by the existing disinfectant, a significant amount of harmful microorganisms are detected, whereas in the case of the litter treated with chlorine dioxide, it is possible to obtain a higher bactericidal effect than the litter sterilized by the conventional disinfectant. there was. Therefore, chlorine dioxide water treatment is suitable to ensure microbiological safety of litter in cages.
