DIARREIA EM BEZERRAS LEITEIRAS, CARACTERIZAÇÃO DOS PRINCIPAIS AGENTES – REVISÃO DE LITERATURA

Abstract

Diarrhea is one of the most common and worrisome pathologies found in calves, due to its high rates of morbidity and mortality, as well as the high costs caused by its prophylaxis and treatment, in addition to being often responsible for losses in future performance. animals and consequently more losses for the owners. These losses can be due to both young animals and adult animals of the dairy herd, as in this age group there is a loss when it comes to reproductive development, in addition to being able to infect future dairy dams, in different ways and often intensely . Treatment is the tool that will help to minimize losses from this pathology, however prevention is the main factor for the losses to be remedied. Colostrum proves to be a determining factor in preventing the disease, being offered at the right time and in the right quantities and qualities, thus ensuring the supply of sufficient immunoglobulins for the animal to be able to produce its own protection against the main causative agents such as bacteria, viruses and protozoa. The aim of the present study was to report the main causes of diarrhea present in the herd of dairy heifers, specifically how the pathogens will act in the organism of these animals, characteristic clinical signs, prophylaxis, diagnosis and treatment for this disease.
