SUMMARY:

The objective of this work was to evaluate the effect of two varieties of cochineal-resistant spineless cactus on histology and histomorphometry of renal parenchyma of sheep. Thirty-six lambs (21.0 ± 2.0 kg of body weight) were distributed in a completely randomized design, with three treatments and twelve replications. For 90 days, the animals received a diet containing Tifton hay as exclusive roughage (control) and two more diets in which the hay was partially replaced by cladodes from Miúda cactus or Mexican Elephant Ear (O.E.M.). Blood samples were collected 50 days after introduction of the tested diets to determine indicators of energy and protein metabolism, as well as, after slaughter, kidney fragments were collected for histopathological and histomorphometric analysis. Larger areas of renal corpuscle, renal glomerulus and Bowman space were observed in animals fed on a diet with palm cladodes, regardless of genotype (p>0.05). The lesions caused in the kidneys of sheep by forage cactus, Miúda and O.E.M. genotypes, are similar to diets with Tifton hay, however, caution is needed when using these cactus forage genotypes in sheep feed.
