Resumen : In order to advance towards the attainment of productivity in swine production, the adequate knowledge of the anatomy, as well as of the reproductive physiology of the sow is essential. In terms of production, one of the parameters that greatly influence productivity is the number of pigs weaned by sow per year, as this parameter determines the number of pigs delivered to the market. This parameter is directly influenced by the reproductive performance of the herd. Reproductive failure is one of the major causes of culling sows; therefore, a thorough examination of the reproductive tract is a valuable diagnostic tool in swine reproductive management. The evaluation of these organs provides us with a series of data on the possible causes of reproductive failure. At the same time, such an evaluation, will allow us to take corrective measures in the herd. In Venezuela, there is no available data describing the pathological findings observed in the reproductive tract of culled sows. The purpose of this investigation was to describe the pathological findings that affect the reprodcutive tract of culled sows. Samples were collected from a slaughterhouse, located in the State of Aragua, Venezuela. A total of 125 reproductive tracts was collected. Results of this investigation show that only 23 animals (18.4%)exhibited abnormal findings which were classified as follows: 8.94% (11/123) sows with inactive ovaries or anestro (neither corpora lutea nor follicles, or follicles with a diameter < 5 mm); 13.01% (16/123) had evidence of ovarian cysts, and 5.6% (7/125) showed uteri with purulent material: one had a retained fetus in decomposition process, and another lacked an oviduct (blind horn); 17.6% of the animals showed inflammatory processess compatible with endometritis.
