Abstract

In Hungary, the losses due to death and culling have significantly increased in broiler flocks since the summer of 1994. Mainly diseases caused by different viral infections, varying flock by flock, and bacteria (E. coli, salmonellae and recently Ornithobacterium rhinotracheale) were detected in the background. In the infected flocks, the grade of losses was decisively influenced by the hatching hygiene and in relation to that by the quality of day-old chickens, as well as by the deficiencies in the environmental requirements of high yielding broilers (especially the population density/m2, quality of air and bedding, as well as the method of drinking and purity of water). Losses are increased when the farm is populated protracted. The in vitro effective antibiotic or sulfonamide treatments hardly influence the losses in the already diseased flocks. The losses could be diminished even in affected flocks when the hatching hygiene was improved (by the appropriate disinfection of egg shell!), the rules of epizootiological protection (by an appropriate vaccination schedule against the existing viral infections in the flock) and technology were maintained. In flocks already diseased, better results could be obtained by diminishing significantly the population density/m2 and improving the efficacy of ventilation than by any kind of repeated drug medication.
