Evaluación de la ganacia de peso en cerdos inmunocastrados y cerdos castrados quirurgicamente en el municipio de Ocamonte Santander.

Abstract

The present research grade work was carried out at the El Carmen Chiquito farm, located in the municipality of Ocamonte, Santander with the objective of comparing weight gain and feed conversion in immunocastrated pigs and surgically castrated pigs. A sample of 29 male pigs resulting from the cross between the Large White and Pietrain breeds was used. From the sample, 14 male pigs that were surgically castrated and another sample of 15 pigs that were immunocastrated were taken. The product used for immunocastration was Innosure® at a dose of 2 ml subcutaneously for both the first and second applications. Each pig was weighed at birth, at weaning and at the processing plant. The amount of concentrated feed they consumed from the weaning date to the departure date was also taken into account. The data obtained were compared through bar and line graphs. The result was that immunocastration leads to better exit weights, better feed conversion and better weight gain than surgical castration; however, the discrepancy between immunocastration and surgical castration was not significant.
