Influence of Blood Urea Concentrations os Subclinical Hypocalcemia in Dairy Cows of the Ductch Race
Subclinical hypocalcemia, NNP, Dairy Cows, Urea Concentrations and Metabolic Disease
It is a metabolic disease that affects cattle, especially animals with high milk production, which is the lowering of serum calcium and a subsequent number of other problems, such as decubitus and paresis, among others. More severe Hypocalcemia (Ca <5 mg/dl), is a serious problem from a economic point of view, since if it is not readily controlled can lead to loss of the affected cow, on the other hand, subclinical hypocalcemia plays a more insidious role leading to loss of production and fertility. Understanding the pathogenesis of subclinical hypocalcemia is of great importance for the establishment of preventive measures and reduction of clinical, milk production and animal management effects. The objective of this study is to verify if subclinical hypocalcemia is closely related to the excess of non-protein nitrogen (NNP) of dairy herds in the weat os state the Santa Catarina. And if this excess influences the blood urea concentrations of these animals can be used with indicative of subclinical hypocalcemia in milk cattle.
