The effects of diets containing cactus cladodes genotypes resistant to Dactylopius opuntiae on the hepatic condition of crossbred male goats were evaluated. Thirty-six goats (19.0 ± 2.8 kg body weight) were distributed in a completely randomized design, with three treatments and twelve replications. For 70 days, the animals were provided with a diet containing Tifton hay as exclusive roughage (control) and two more diets in which the hay was partially replaced by Miúda or Orelha de Elefante Mexicana (O.E.M.) cactus cladodes. Blood samples were collected one day before (baseline) and 50 days after the introduction of the tested diets to determine enzyme activities, bilirubins concentration and indicators of energy and protein metabolism, as well as, after slaughter, liver samples were collected for histopathological analysis. The use of cactus cladodes, regardless of genotype, decreased the serum concentration of cholesterol (P = 0.0023), whose averages were 73.24; 51.55 and 56.93 mg/dL, for the control treatments, with Miúda and with O.E.M. cactus cladodes, respectively. The animals that consumed cactus cladodes showed a predominance of degenerative and inflammatory processes and the O.E.M. cactus cladodes caused diffuse and accentuated coagulative necrosis in liver tissue (P = 0.0334). The cactus cladodes causes a decrease in serum cholesterol and, especially the O.E.M. genotype, causes outstanding tissue damage in the liver of goats, without affecting productive parameters.

含有仙人掌叶状枝基因型耐药饮食的影响Dactylopius opuntiae上杂交公山羊的肝条件进行了评价。以完全随机的设计分配了36只山羊（19.0±2.8 kg体重），进行了三种处理和十二次重复。在70天之内，为动物提供了含有蒂夫顿干草作为独家粗饲料的日粮（对照），以及另外两种日粮，其中干草被Miúda或Orelha de Elefante Mexicana（OEM）部分替代了）仙人掌。在引入测试饮食的前一天（基准）和后50天收集血液样本，以确定酶活性，胆红素浓度以及能量和蛋白质代谢指标，以及在屠宰后收集肝脏样本以进行组织病理学分析。不论基因型如何，使用仙人掌枝均可降低血清中的胆固醇浓度（P = 0.0023），平均值为73.24。分别用Miúda和OEM仙人掌进行了51.55 mg / dL和56.93 mg / dL的对照治疗。食用仙人掌枝的动物表现出变性和炎症过程以及原始设备制造商（OEM）的优势。仙人掌丛在肝脏组织中引起弥漫性和加重性凝血坏死（P = 0.0334）。仙人掌丛可降低血清胆固醇，尤其是OEM基因型，可在山羊肝脏中引起显着的组织损伤，而不会影响生产参数。
