COMPOSIÇÃO CORPORAL DE CÁLCIO E FÓSFORO EM CABRAS GESTANTES DA RAÇA MOXOTÓ NO SEMIÁRIDO PARAÍBANO

Abstract

Aimed to evaluate the influence of gestational age, number of fetuses and levels of food restriction on the composition of minerals Ca and P in maternal body, gravid uterus, fetus and mammary gland of goats Mocotó. 80 multiparous lactating goats of which 8 were nonpregnant animals slaughtered and used as reference, the other 72 induction and synchronization of estrus were submitted through the use of hormones, then were covered, thirty days of coverage were used was diagnosed gestation by the use of ultrasound and the time the count was taken of the fetuses were then grouped according to their gestational age (50, 100, and 140 days) of gestation (single or twin) and the level of food restriction (0%, 20% and 40%).

The design was completely randomized with factorial 3 x 2 x 3 (Three gestational age, number of fetuses Two and Three levels of restriction). For the determination of nutrients retained in the components of pregnancy comparative slaughter technique was used. Slaughter was carried out according to the gestational stages by concussion then bleeding. Blood was collected and weighed as well as the gastrointestinal tract, and all individual organs. The udder and gravid uterus (womb, fetuses, fetal structures and liquid) were removed, weighed and frozen. The samples were ground, homogenized, lyophilized and crushed later laboratory analyzes were performed.
