Pathologies of uncertain etiology manifested by gastric ulcers have been observed in pig. This research paper shows the association of Helicobacter sp. as the main causing agent of this disorder by studying a sample of 100 pigs slaughtered at the Vijagual abattoir in the Bucaramanga city. Sera samples were analyzed and samples of gastric tissue were processed by histopathological methods using Hematoxiline-Eosine and Warthin-Starry to confirm the correlation between spiral bacteria and gastric lesions. Blood sera of positive pigs in the histopathological examination were examined by a specific chromatographic device or immunoassay (ACON ®). Analysis of results was based on a experimental model describing the number of positive and negative pigs to Helicobacter sp. bacteria. Histopathologically, 53% of the animals were positive and 47% were negative. The species of bacteria assosiated were Helicobacter pylori (60,3%) and Helicobacter hellmanii (39,6%). For the serological procedure, 25 positive and 25 negative samples to Helicobacter sp. were analyzed. A reliability of 92% with the specific test and 75% of negative confirmation was found. The statistical test of Chi Square was utilized to evaluate the association of Helicobacter sp. to gastric lesions. Standardization was carried out by the ACON ®specific chromatographic device. This test is designed for the detection of IgG antibodies against Helicobacter pylori in human serum for the diagnosis of gastrointestinal diseases. Based on this method, reliability and specificity of the test was demonstrated for the determination of Helicobacter pylori in sera of pigs with gastric lesions. This technique represents a precise aid for the management of gastric clinical malfunctions that are frequentin porcine exploitations nowadays.    

El presente estudio, se realizó en la Granja Villa Alejandra, Vereda Guamo Pequeño, Municipio de Piedecuesta, Santander, donde se propuso como objetivo evaluar una dieta no convencional a base de los subproductos industriales de la región y forrajes propios de la finca.Partiendo del día 0 hasta el día 114 se desarrollo la experiencia con 30 cerdas híbridas Large White por Landrace y Landrace por Pietrain, con uno o más partos cada una, estas fueron distribuidas al azar en dos tratamientos de 15 cerdas para el grupo experimental y 15 para el grupo control; en cada cerda se evaluaron los parámetros: Score, tamaño y peso de la camada al nacimiento, medición de la grasa dorsal de la cerda al inicio y fin del periodo de gestación.Las cerdas del grupo control fueron manejadas de acuerdo a los procesos zootécnicos de la porcicultura convencional, ofreciendo una ración de alimento a base de concentrado comercial acorde a las etapas de gestación, mientras que el grupo experimental consumió una dieta equivalente en proteína, aportada por Trichanthera gigantea, y como fuente de energía, melaza de caña, aceite crudo de palma y subproductos de molinería como repila de arroz y mogolla de trigo.
