Abstract

A cecostomy technique (surgery for inserted tube into ceca) was developed to quantify urine backflow into the ceca of fed and feed-deprived chickens. Two days post-surgery, cecostomised chickens were flushed with 20ml of warm saline solution every other day for 10 days. Excreta were collected daily from cecal tubing and cloaca by surgical attachment of polyethylene collection vessels to the chickens. Uric acid excretion was significantly increased in fed compared to feed-deprived chickens (P<0.05). Amount of determined uric acid from the ceca was 7.74% and 5.31% of total excretion for fed and ffeed-deprived chickens, respectively. Post-mortem examinations ascertained that the caeca were intact around the Latex tubing. The results of the study indicated that at least 5% of daily urine production flow retrograde into the ceca of roosters.

닭에서 맹장으로 尿의 역류량을 측정하기 위해서 사료급여 및 절식의 조건에서 Cecostomy(맹장으로 튜브를 삽입하는 수술) 기술이 개발되었다. 시술 이틀 뒤부터 맹장에 튜브가 장착된 닭은 20ml의 따뜻한 생리적 식염수를 이용하여 격일 간격으로 10일동안 수술부위를 환류시켰다. 맹장에 장착된 튜브와 총배설강에 외과적으로 시술된 플라스틱 채집병을 이용하여서 배설물이 매일 모아졌다. 요산 배설량은 사료 채식시가 절식시 보다 유의하게 증가하였다.(P<0.05) 맹장을 통해서 검출된 요산의 양은 사료급여시와 절식시에 각각 총 요산 배설량의 7.74, 5.31%를 나타내었다. 사후검사에서 맹장에 삽입되었던 고무튜브 주위를 둘러싸고 있는 완벽한 맹장이 확인되었다. 본 연구의 결과 수탉에서 적어도 매일 약 5%의 尿가 맹장으로 역류됨을 알 수 있었다.
