D.

Sobral, Northeast Brazil, giving a mean incidence of 50%. The high incidence of abortion did not have an infectious origin because microbiological culture, histological and serological examinations of placenta, fetus and maternal blood were all negative. Biochemical analyses of the maternal blood samples showed very low levels of Mg (0.14 .+-. 0.07 mg/100 ml), Cu (0.086 .+-. 0.009 mg/100 ml), Mn (0.14 .+-. 0.06 mg/100 ml), I (3.05 .+-. 0.71 mg/100 ml), P (6.50 .+-. 2.15 mg/100 ml) and total protein (6.41 .+-. 0.71 g/100 ml). The low levels of these elements in the maternal blood corresponded with the low nutritional levels of the goats' diet during the dry season. The high incidence of early abortion could be associated with deficiencies in protein, P, Mg and Cu. Further studies, including studies of non aborting does, will be conducted to test whether these and/or other deficiencies provoke this abortion.  aAnimal nutrition  aBrazil  aCopper  aGoats  aIodine  aManganese  aPhosphorus  aPregnancy complications  aProtein deficiencies  aReproductive disorders  aSemiarid zones  aAborto  aCaprino  aCobre  aDistúrbio nutricional  aFósforo  aMagnésio  aManganês  aNutrição animal  aPrenhez  aAbortion  aBrasil  aDeficiência nutritional  aMicronutriente  aNutritional disorders  aSemiárido  aTrace element1 aSILVA, E.
