糞腸球菌在養殖生產中的應用

更新時間:2018-08-18 15:41:39點擊次數:5320次
糞腸球菌能夠提高家禽的生產性能。研究表明,產蛋雞日糧中添加糞腸球菌可降低料蛋比,提高蛋重和產蛋率,改善蛋品質。唐文富等研究發現,在日糧中添加糞腸球菌可降低蛋鴨的耗料量和料蛋比,提高總蛋重,進一步發現日糧中添加糞腸球菌對提高蛋鴨的蛋品質同樣效果顯著。糞腸球菌通過增殖有益菌、抑制有害菌,調控腸道菌群平衡,促進腸道內合成大量的維生素、酶等物質,提高飼料的消化利用率,從而提高生產性能。

糞腸球菌對豬免疫功能的影響

動物體液免疫對抵抗疾病有重要作用,血清免疫球蛋白的含量可反映出體液免疫功能。糞腸球菌可提高豬血清中IgG和IgA含量,這表明糞腸球菌對提高豬的體液免疫有積極作用,其原因可能是糞腸球菌產生某些蛋白質和多肽類物質刺激機體的免疫系統。器官指數是生物學指標之一,一定程度上反映機體器官功能的強弱。史自濤等研究表明,糞腸球菌可在一定程度上促進斷奶仔豬肝臟和脾臟的發育,改善其免疫功能,其原因可能是由于糞腸球菌自身作為一種抗原物質,有效刺激肝臟和脾臟的生長發育,另外糞腸球菌在斷奶仔豬腸道中生長繁殖,合成的一些有益成分可能會對肝臟和脾臟的發育產生一定的刺激作用。
