    abstract = {A study was conducted to examine the efficacy of dietary mineral supplementation (CaPO<SUB>4</SUB> and MgSO<SUB>4</SUB>. 7H<SUB>2</SUB>O) on the milk mineral (Ca, P, Mg and K) content of the West African dwarf, WAD, goats. Eighteen monoparous lactating WAD does were utilized for feeding trial in a 12-week lactation period in which the does were randomly assigned to one of the three dietary treatment groups (A, B, C) of six animals in a completely randomized design. The three isonitrogenous (15% CP) and isocaloric (2.34 Mcal ME) supplementary diets fed to a based diet of <I>Panicum maximum</I> grass contained graded levels (%) 0, 1 and  2 of Ca/P and Mg supplementations in diets A, B and  C respectively. Results showed that treatment effects on dry matter intake, DMT (kg day<SUP>-1</SUP>), body weight (Bw) gain (g day <SUP>-1</SUP>) circulating levels (mg dL<SUP>-1</SUP>) of Ca, P, Mg and K in serum and milk of WAD does were significant (p&lt;0.05). Similar effect on milk yield was highly significant (p&lt;0.01). The mean values (mg dL<SUP>-1</SUP>) of circulating levels of CA, P, Mg and K in serum of WAD does on diets A, B and C were: Ca 9.75, 10.00 and 10.13, P 7.15, 7.57 and 7.79; Mg 3.20, 3.52 and 4.54 and K (mmolL<SUP>-1</SUP>) 3.53, 3.83 and 3.77, respectively; while corresponding values (mgdl<SUP>-1</SUP>) in milk were Ca 121.0, 127.0 and 132.0; P 84.5, 89.78 and 94.08; Mg 18.90, 41.82 and 47.61; and K 158.43, 165.03 and 160.58. The general trend was that increasing dietary mineral supplementation effected a concomitant increase in milk mineral (Ca, P, Mg and K) outputs. Significant positive correlations (r = 0.99, 0.97, 0.73 and 0.85) existed between serum and milk Ca, P, Mg and K contents respectively suggesting that blood is a secondary source of milk mineral secretion in lactating animals.}
