β-羟基-β-甲基丁酸在水产动物中应用的研究进展(下)
HMB 是一种非常有应用前景的营养补充剂,已经在临床和动物中有了大量的试验及应用,且已证明了其安全。HMB 具有多种有益作用,包括促进肌肉蛋白质合成、抑制肌肉蛋白质降解、提高肌肉品质和免疫力等。同时,HMB 是一种无氮补剂,应用于水产动物养殖中对水体的污染小,不会造成水体中氨氮和亚硝酸含量的升高。
因此,HMB 作为饲料添加剂,在提高水产养殖动物生长性能、肌肉品质和免疫功能方面具有非常广阔的应用前景。HMB 的作用机制非常复杂,目前还在探索阶段,需要大量的试验验证。HMB 在水产动物中的应用和研究非常有限,许多在畜禽动物中常见的研究在水产动物尤其是甲壳动物中却鲜有报道,未来需要大量的研究来验证HMB 在水产动物中的作用及其机制。
