Abstract

ABSTRACT This study aimed to evaluate the effect of the inclusion of spineless cactus (Opuntia stricta Haw) in the diet of sheep on the balance of macrominerals, renal function, and blood metabolites. Five sheep cannulated in the rumen (61.5±9.5kg body weight) were used in a 5 × 5 Latin square composed of five diets and five experimental periods. The experimental period lasted 105 days, with five periods of 21 days each. Four diets containing levels of spineless cactus (121, 245, 371, and 500g/kg of dry matter (DM)), and a control diet were evaluated. Samples of the ingredients, orts, feces, urine, and blood were collected. Spineless cactus inclusion in sheep diets increased the DM intake, ash, oxalate, and all macrominerals intake (P < 0.05), but did not affect the urinary and fecal excretion of P, as well as the concentration of P in the blood (P > 0.05). It is possible to verify that the inclusion of spineless cactus, up to the level of 500g/kg of DM in the sheep diets, does not appear to cause damage to the animal’s health. Its inclusion does not compromise kidney function or blood metabolites evaluated herein.

严格仙人掌的营养和矿物质组成：绵羊体内大量矿物质、肾功能和血液代谢产物的平衡

摘要本研究旨在评价绵羊日粮中添加无刺仙人掌(Opuntia stricta Haw)对巨量矿物质、肾功能和血液代谢物平衡的影响。试验选用5只体重为61.5±9.5kg的瘤胃空心羊，采用5 × 5拉丁方格试验，共设5种饲粮和5个试验期。试验期105 d，共5期，每期21 d。研究了4种无刺仙人掌饲粮(干物质水平分别为121、245、371和500g/kg)和对照饲粮。收集成分、内脏、粪便、尿液和血液样本。绵羊饲粮中添加无刺仙人掌增加了干物质摄入量、灰分、草酸盐和所有常量矿物质摄入量(P < 0.05)，但对尿、粪中磷的排泄量以及血液中磷的浓度没有影响(P < 0.05)。可以验证的是，在绵羊日粮中添加500克/公斤的无刺仙人掌，似乎不会对动物的健康造成损害。它的加入不会损害肾脏功能或血液代谢物。
