Abstract

The purpose of this paper was to characterize mortality and discard in the first week of life of chicken for fattening, taking into account the most prone causes affecting birds at their early age by considering macroscopic injuries and by conducting an external evaluation to allow stricter identification in the selected specimens for discard. The activity was carried out on the farm EL ROBLE, located on the Irapire path of the municipality of Curití, department of Santander, Colombia. The birds were divided into 4 ages according to the order of arrival at the farm, with a total of 212,262 animals coming from the same breeding farm, but from different batches. The characterization was performed by external observation and necropsies for the analysis of macroscopic lesions. A total of 1,168 necropsies were performed within 14 days, carried out in the first 7 days of consumption of each age, and also taking into account transport mortalities. At the time of reception, the first weighing of 1 box of birds per section was carried out in each pool and the sewage temperature of 200 birds was taken in order to have an estimated average, data that will provide us with information on the level of stress they reach the farm. In another group of 200 birds, the were followed up on uniformity, since these specimens were identified by in marking and weighing at the time of reception, on 5 and day 8, which is continuing to date. The data collected from the necropsies were tabulated and represented as a percentage by graphs and based on this respective discussion.
