A completely randomized design was used (CRD). Sampling was done on two stages at flowering and seed setting in selected locations (2 km2 each). Within each stage 60 goats randomly selected, randomly collected samples of blood serum. Stages had significant (P< 0.0001) effect on blood serum of goats was highly K (5.10-3.88 mmol/L) concentration at flowering stage and least during the seed setting stage respectively. Concentration of P (2.96-3.94mg/dl) were decreased at flowering stage and increased at seed setting stage respectively. It can be concluded that at the flowering stage highly potassium concentration and decreased phosphors concentration. However during the seed setting stage least potassium concentration and increased phosphors concentration.
