This work was carried out to estimate the retention and the net requirements of Ca and P, in 120 goats averaging 42 kg LW. The estimate retention based in the difference between the total of each mineral stored in the fetus, the uterus, the membranes, the fetal fluids and the mammary gland of animals in the different phases of pregnancy and the total of each mineral stored in the empty goats. The model of prediction used was lnY = A […]
