Comparative Effect of Cecal Ligation and Colostomy on Nitrogen Utilization in Chickens Fed Low Protein or Urea-Supplemented Low Protein Diets

A study was carried out to investigate nitrogen metabolism in response to cecal ligation and colostomy in chickens. We used colostomized plus ceca-ligated chickens fed a low protein diet or a low protein diet supplemented with urea. When both types of diets were fed, nitrogen balance and utilization tended to increase by cecal ligation while total nitrogen excretion tended to decrease. Colostomy increased total nitrogen excretion and decreased nitrogen balance and utilization in chickens fed both types of diets. Therefore, total nitrogen excretion, nitrogen balance and utilization were significantly different between the ceca-ligated and colostomized chicken fed both types of diets (P
