Extract

Polyunsaturated fatty acids (PUFA), especially the n-3 and n-6 families are dietary compounds with significant immunomodulatory potential. Mechanisms proposed to explain their impact on immune function include (1) direct effects on leukocyte and epithelial cell membrane function, (2) the regulation of expression of immune genes and their products and (3) eicosanoid-mediated mechanisms (Hwang, 2000). Eicosanoids are immune effector molecules which have important roles in the regulation of immune and inflammatory responses (Calder, 2001). The aim of this experiment was to establish the extent to which supplementation of pre-ruminant calves with an n-6 or n-3 PUFA source may influence mucosal mast cell numbers in the abomasum (ABO), duodenum (DD) and terminal ileum (TI).
