Popis: This experiment involved 12 West Africa goats aged 20 to 24 months and weighing 21 to 23kg. They were fed a basal diet of grass hay (Cynodon nlemfuensis) and randomly allotted to one of three isonitrogenous and isocaloric concentrate diets. Concentrate contained Ca 0.42% and P 0.28% (A), Ca 0.81% and P 0.55% (B) and Ca 1.21% and P O.81(C). The experiment lasted 12) weeks of lactation. Results show that dry matter intake (DMI) was between 4.2 and 4.5% of body weight (BW). Treatment effect on blood glucose (BG) and plasma urea nitrogen (PUN) was not significant. Effects of week and time of blood collection were highly significant (P
