Abstract:
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%).
