Resumo: |
Three experiments were designed based in evidences that the calcium have the important role in the energetic metabolism of ruminants. The first experiment tested the possibility of use the Ca2Cl as diagnostic in impaired of insulin secretion and glucose metabolism in pregnant ewes. In the others two we researched the hypocalcemia effects in the metabolic profile of dairy cows in good body score condition during prepartum and ewes that were in chronic negative energetic balance. The calcium infusion during the late gestation seems no change insulin secretion and glucose metabolism during the glucose tolerance test. However, new investigation about the form of administration and the dose to ruminant need to be review. In dairy cows that were in good body condition score in prepartum the hypocalcemia seem has been responsible to change the energetic status. Nevertheless hypocalcaemic ewes that were in chronic negative energetic balance, the energy status was not changed. These founds suggest that the hypocalcemia could be responsible to induce the negative energetic balance in ruminants, but this effect may be dependent of adaptations conditions in the prepartum. |
