The objective of this study to evaluate the nutritional value of cactus pear grown under different planting spacings and doses of cattle manure applied to soil. The experiment was implemented in an Oxisol in Guanambi, Bahia. The experimental design was randomized blocks with 12 treatments arranged in a factorial 3 x 4, four doses of cattle manure (0, 30, 60 and 90 Mg ha-1 yr-1) and three planting space, two in single rows (1,0 x 0,5 and 2,0 x 0,25 m) and a double row in (3,0 x 1,0 x 0,25 m) and three repetitions. In the planting spaces used, the same population density of 20,000 plants ha-1 was maintained. The nutritional value of cladodes was evaluated at 600 days after planting. Data were subjected to analysis of variance and subsequently comparisons were made between the means of different spacings by the Tukey Test and regression analysis for the different doses of manure and, when significant, interactions were unfolded. The manure of cattle increasingly influenced the content of crude protein, total nitrogen, protein and rapid intermediate degradation. There was a decrease in hemicellulose levels, total carbohydrates, neutral and acid detergent insoluble nitrogen as a function of total nitrogen and indigestible protein. Thus, the increase in doses of manure applied to soil improves the quality of the nutritive value of forage palm and planting spaces barely influence the quality of cactus pear.
