1 Definition, Etiology and Epidemiology

Transcript

Greetings to all!!

Today’s topic is about Bovine Postpartum hemoglobinuria. It consists of four lesson. Lesson number one is about definition of the Disease, importance of the disease, and Causes, and second lesson is about the Etiopathogenesis, third lesson is about the clinical findings and clinical Pathology, fourth lesson is about the treatment and management of postparturient hemoglobinuria.

Now coming to lesson number one, first slide we are going to see about what is the definition of the bovine postpartum hemoglobinuria. It is a non-infectious hemolytic syndrome of adult cattle and buffaloes. This is mainly characterized by intra-vascular hemolysis, Hemoglobinuria, severe anemia and death is mainly due to anemic anoxia. So, the phosphorus deficiency that is occurring during the early stages of the pregnancy or sorry early stages of the lactation is widely believed to be associated with this condition.

Exact pathogenesis is not completely understood and it is commonly seen in case of high yielding dairy cause especially during the third to sixth lactation and multiparous animals are affected more commonly, and the disease is found to be, the prevalence is found to be more common during the first month of lactation or after carving, and the higher incidence, this is the third slide I am going to talk about and it is high most commonly seen in case of high yielding dairy cause during the winter month. And risk factors what are all the risk factors that are associated with or which predisposes the animal for postpartum hemoglobinuria is ingestion of the cruciferous plant such as cabbage, onion, cauliflower and radish, and this cruciferous plants or beet pulp are low in phosphorus. Another one of the most important factor, this is the fourth slide I’m talking about another most important factor that is predisposing the animal to postpartum hemoglobinuria is copper deficiency. So, low copper status which is related to the application of high molybdenum or sulphur will lead to copper deficiency. And another one is, another common important factor is phosphorus deficient soils and drought conditions also predisposes the animal to hypophosphatemia and the last important factor that predisposes the animal to postpartum hemoglobinuria is ingestion of excess of cold water or exposure of the animal to extreme cold weather will precipitate an episode of postpartum hemoglobinuria. So, in this first lesson we have seen about the definition, the factors or the causes that are leading to the Hypophosphatemia. In the coming session, we will see about the etiopathogenesis and clinical findings, clinical pathology, and treatment.
