Resumo: The objective of this work was to determine the nutritional value of spineless cactus varieties resistant Cochineal carmine (Dactylopius opuntiae Cockerell), “Orelha de Elefante Mexicana” (Opuntia stricta), “IPA-Sertania” (Nopalea cochenillifera), “Miuda” (Cochenillifera Nopalea Salm-Dyck), IPA-21 F (Nopalea cochenillifera). Used 24 sheep SPRD with initial weight of 21.0 ± 0.5 kg, distributed in a randomized complete block design with four treatments and six repetitions. The experimental diets were composed of cactus, soybean (Glycine max (L.)), urea and mineral salt farming. The intakes of dry matter, organic matter, neutral detergent fiber and digestible energy were, on average, 3.4% PC, 2.9% CP, 0.72% CP and 2.8 Mcal / day, respectively, and were not influenced by the variety of the palm. The digestibility of DM and OM were higher in diets composed by “Orelha de elefante Mexicana” “IPA Sertania”, compared to a diet composed by “Miuda” variety. The digestibility of NDF and energy were not influenced by the variety of palm and were, on average, 46.3% and 72.4%. The experimental diets did not influence weight gain or carcass yield, which averaged 89.0 g / day and 52.4%, respectively. The animals were given an average of 62.2 ml of water / day for two consecutive days every 3.3 days. The Mexicana varieties of “Orelha de elefante” (Opuntia stricta), “IPA-Sertânia” (Nopalea cochenillifera) and “IPA-F21” (Nopalea cochenillifera) can be fed to sheep without compromising its performance.
