The effects of Ascophyllum nodosom on immune function, performance, and carcass characteristics of sheep and cattle

Two experiments were conducted to evaluate the efficiency of Ascophyllum nodosum (Tasco) fed to sheep or cattle. In experiment 1, 54 wether lambs were fed Tasco-14 (meal) or Tasco- EX (extract) at dietary levels of 0.0%, 0.25%, 0.50%, 1.0% and 2.0%, to determine performance characteristics, carcass characteristics and immune function traits. There were no differences among all treatments for performance characteristics (P>.05), carcass traits, and hnmune response (P>.05). Immune response was also not different (P>.05) among the extract, meal and control diets.
