Objective. identify the presence of chicken anemia virus (CAV) in poultry farms and backyard chickens from Antioquia, Colombia. Materials Methods. Blood feather samples were taken laying chickens; each farm, three birds six different ages (1, 15, 30, 60, 90, 120 days old) chosen randomly. Backyard also obtained near research farms. We used serology molecular techniques to analyze samples. Resul...

The present study was designed to investigate the prevalence of Salmonella species, their molecular characterization and antibiotic resistance in backyard chickens. A total of 1125 samples were collected from backyard chickens in two consequent samplings. In the first part, samples were included of 820 poor recently hatched chicks, hatching residuals, egg shells in the nest floor, cloacal swabs...

We analyze situations in which a group of agents (and possibly a designer) have to reach a decision that will affect all the agents. Examples of such scenarios are the location of a nuclear reactor or the siting of a major sport event. To address the problem of reaching a decision, we propose a one-stage multi-bidding mechanism where agents compete for the project by submitting bids. All Nash e...
