β-羥基-β-甲基丁酸在水產(chǎn)動物中應用的研究進展(下)
HMB 是一種非常有應用前景的營養(yǎng)補充劑,已經(jīng)在臨床和動物中有了大量的試驗及應用,且已證明了其安全。HMB 具有多種有益作用,包括促進肌肉蛋白質合成、抑制肌肉蛋白質降解、提高肌肉品質和免疫力等。同時,HMB 是一種無氮補劑,應用于水產(chǎn)動物養(yǎng)殖中對水體的污染小,不會造成水體中氨氮和亞硝酸含量的升高。
因此,HMB 作為飼料添加劑,在提高水產(chǎn)養(yǎng)殖動物生長性能、肌肉品質和免疫功能方面具有非常廣闊的應用前景。HMB 的作用機制非常復雜,目前還在探索階段,需要大量的試驗驗證。HMB 在水產(chǎn)動物中的應用和研究非常有限,許多在畜禽動物中常見的研究在水產(chǎn)動物尤其是甲殼動物中卻鮮有報道,未來需要大量的研究來驗證HMB 在水產(chǎn)動物中的作用及其機制。
