Cactus pear is used in animal feed because its pads are rich in water and mineral elements.
The aim of this work was to determine the nutritive value of 2 cultivars of Opuntia ficus-indica (Aissa (A) and Moussa (M)) in two regions (Agadir area (Ag) and Sidi Ifni area (Si)) and to compare between them in a same locality in Ag area.
Obtained results showed that N level in both cultivars is higher in Si area (1.50% for M and 1.33 for A) than in Ag area (1.03% for M and 0.86 for A) and their level in P is also higher in Si (0.20% for M and 0.090 for A) than in Ag (0.092% for M and 0.084 for A). M met crude proteins (CP) requirements of dairy cows in Si area (9.37%) and that of dry cows in Ag area (6.43%), and A met the CP requirements of dry cows in Si area (8.31%). However, both cultivars met the CP level adequate for sheep and goats in both areas (5.37-9.37%). M also met P requirements of dry cows in Si (0.20%) and both cultivars met that of sheep and goats in the two areas (0.084-0.20%). Both cultivars met Ca and Mg requirements of cattle in both areas (3.99-5.12% Ca and 0.22-0.30% Mg) and not the needs of beef in Na (11-15 ppm), and M met the K requirement of beef in Si area (0.65%).
