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.
