The Effect of Jerusalem Artichoke (Helianthus tuberosus L.) on Blood Parameters, Liver Enzymes and Intestinal pH in Laying Hens

Abstract

A study was conducted to determine the effect of, as a source of inulin, Jerusalem artichoke on intestinal pH, some blood parameters and liver enzymes of laying hens. Control and treatment groups were fed a diet containing 0, 5 and 10% Jerusalem artichoke, respectively. Twenty five weeks old, 45 commercial white laying hens were used in the experiment. In this experiment, inulin was effective on modifying of intestinal characteristics, blood metabolites and liver enzymes in laying hens. Fecal and intestinal pH values were not altered by dietary treatments. Although, unchanged serum cholesterol and albumen content, 5% JA increased glucose (p<0.001) and decreased fructose (p<0.01), triglyceride (p<0.01) and total protein (p<0.05) contents when compared with control diet. On the other hand, 10% JA reduced serum glucose as well as fructose levels. Serum SGOT levels was increased (p<0.01) by 5% JA addition and ALP levels was decreased (p<0.05) by 10% JA.
