Revisión bibliográfica de las principales enfermedades presentes en feedlots y su repercusión en la producción

Abstract

This work focuses on describing the main diseases (Bovine respiratory complex, acidosis, tympanism, keratoconjunctivitis and scabies) most prevalent in feedlots. In some of the establishments located in the Middle Valley, surveyed during the OPP, animals were found that presented signs compatible with some of these pathologies, although there are no regional epidemiological studies that provide support and/or can be used as a reference to describe the degree of incidence of these pathologies in the Middle Valley. The objectives of feedlots are to obtain a high production of meat per animal, of quality, and with high conversion efficiency (kilograms of food / kilo of meat), which is why we describe each of them, their treatments, prevention, and their productive impact. The arrival of feedlots in Argentina, as well as in other meat-producing countries in the world, has generated new challenges and demands that livestock farming was accustomed to facing. The proposals for pen confinement, accompanied by a greater concentration of livestock, an element that favors the transmission of diseases, as well as the use of different concentrated products and by-products used in food, are the new challenges faced by Veterinary Medicine. This is how, in a generalized context (national/global), most authors agree that respiratory diseases represent around 70% of the cause of mortality, followed by digestive disorders with 7%. To all this, treatments must be added to the production cost, which represents 8%.
