METABOLISMO DE CÁLCIO E FÓSFORO EM OVINOS

Abstract

We conducted with this review describe the calcium and phosphorus metabolism in sheep as well as discuss the factors inherent absorption of these minerals. The importance of this study is due to the increasing needs of these minerals in the diet due to the breeding of animals for breeding young animals, the phosphorus deficiencies, the increasing incidence of twin births, the increased use of diets with high energy density and the incidence of recurrent hypocalcaemia in the national sheep flock. Calcium absorption rate from the intestine increases steadily throughout pregnancy, however is insufficient to meet the requirements of the ewe in late pregnancy and early lactation. Research related to the use of P by ruminants, and dietary sources of this element must still be developed due to the high cost of this mineral in the mineral mixture
