The red-crowned crane (Grus japonensis) is one of the most vulnerable bird species in the world. Mycotoxins are toxic secondary metabolites produced by fungi and considered naturally unavoidable contaminants in animal feed. Our recent survey indicated that the mycotoxins had the potential to contaminate redcrowned crane's regular diets in China.
This experiment was conducted to investigate the protective effects of mycotoxin binder montmorillonite (Mont) on growth performance, serum biochemistry and oxidative stress parameters of the red-crowned crane.
16 red-crowned cranes were divided into four groups and fed one of the following diets; a selected diet, regular diet, or the selected diet or regular diet with 0.5% montmorillonite added to the diets. The cranes' parameters of performance, hematology, serum biochemistry and serum oxidative stress were measured.
Consuming regular diets decreased the average daily feed intake (ADFI), levels of haemoglobin (Hb), platelet count (PLT), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT), but increased the activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatine kinase (CK) and lactate dehydrogenase (LDH). The supplementation of 0.5% Mont provided protection for the red-crowned crane in terms of feed intake, serum biochemistry and oxidative stress. Moreover, Mont supplementation had no adverse effect on the health of red-crowned crane.
Taken together, these findings suggested that the addition of dietary Mont is effective in improving the health of red-crowned crane.
丹顶鹤是世界上最脆弱的鸟类之一。真菌产生的霉菌毒素是一种有毒的次生代谢物，被认为是动物饲料中不可避免的天然污染物。我们最近的调查表明，霉菌毒素有可能污染中国丹顶鹤的常规饮食。
本实验旨在研究霉菌毒素结合剂蒙脱石（Mont）对丹顶鹤生长性能、血清生化和氧化应激参数的保护作用。
将 16 只丹顶鹤分为四组，分别饲喂以下四种日粮之一：选择日粮、常规日粮或选择日粮或常规日粮，日粮中添加 0.5%蒙脱石。测量鹤的性能、血液学、血清生化和血清氧化应激参数。
饲喂常规日粮降低了平均日采食量（ADFI）、血红蛋白（Hb）、血小板计数（PLT）、超氧化物歧化酶（SOD）、谷胱甘肽过氧化物酶（GSH-Px）和过氧化氢酶（CAT）水平，但增加了天冬氨酸转氨酶（AST）、丙氨酸转氨酶（ALT）、肌酸激酶（CK）和乳酸脱氢酶（LDH）的活性。日粮中添加 0.5%的 Mont 为丹顶鹤的饲料摄入、血清生化和氧化应激提供了保护。此外，Mont 补充剂对丹顶鹤的健康没有不良影响。
综上所述，这些发现表明，日粮中添加 Mont 可有效改善丹顶鹤的健康状况。
