Investigation the Frequency of Pathological Lesions of Sheep Rumen in Sanandaj Slaughter

Rumen health in ruminants has a great importance because its function has a great deal with milk, meat and fetus production. Many factors can affect the rumen health and destruct its function and performance. this research investigates histopathology lesions resulted from ruminants in the sheep. for this purpose, macroscopic examination in 1562 rumens of the slaughtered sheep Sanandaj was done. Among these, 23 rumens has lesions placed in drums of formalin 10% for macroscopic evaluations by means of Hematoxylin and Eosin coloring were referred into the pathobiology lab. in Macroscopic observations, swelling (65.22%), swelling and focal congestion (30.43%) and looming papillary (4.35%) were detected. The highest microscopic signs in the rumen lesions included: sub mucosal edema (32.69%), ruminate eosinophilic (23.07%), parakeratosis (13.46%), granulomatous ruminate (7.69%), watery degeneration and acute purulent ruminate (5.76%). pathologic lesions of rumen can be due to hyperplasia change in the result of mechanical agitation, stress, parasitic diseases, and mature woody forage.
