筆者認為引起斷奶仔兔腹瀉有五個原因：

首先是斷奶應激。斷奶兔常發生應激反映，這種反映來源於三方麵：⑴心理應激，母子分離不習慣；⑵環境應激，仔兔被移至別處不習慣
；⑶營養性應激，沒有奶吃了，僅僅吃料一時難以習慣。

第di三san個ge原yuan因yin，是shi免mian疫yi反fan應ying抑yi製zhi。母mu兔tu初chu乳ru中zhong免mian疫yi球qiu蛋dan白bai含han量liang高gao

，而er新xin生sheng仔zai兔tu的de腸chang壁bi通tong透tou性xing較jiao大da，能neng完wan全quan吸xi收shou初chu乳ru中zhong的de免mian疫yi球qiu蛋dan白bai從cong而er獲huo得de被bei動dong免mian疫yi。隨sui著zhe母mu乳ru中zhong免mian疫yi球qiu蛋dan白bai大da為wei減jian少shao，仔zai兔tu主zhu要yao依yi靠kao主zhu動dong免mian疫yi，隨sui著zhe母mu乳ru的de減jian少shao，母mu源yuan抗kang體ti減jian弱ruo，仔zai兔tu斷duan奶nai時shi出chu現xian反fan應ying，從cong而er降jiang低di仔zai兔tu抗kang體ti水shui平ping
，抑yi製zhi了le細xi胞bao的de免mian疫yi力li，使shi其qi抵di抗kang力li減jian弱ruo，所suo以yi容rong易yi發fa生sheng腹fu瀉xie。

第四個原因，是消化酶的活性降低。消化酶是指仔兔消化道裏的胰脂肪酶、胰蛋白酶
、胃蛋白分解酶等。當仔兔斷奶一周
，這些酶的活性顯著降低，降到斷奶前水平的1/3。其qi主zhu要yao原yuan因yin是shi由you於yu斷duan奶nai後hou乳ru糖tang消xiao失shi，使shi乳ru酸suan來lai源yuan終zhong止zhi
，胃wei酸suan分fen泌mi很hen少shao，此ci時shi胃wei的de酸suan度du降jiang低di
，直zhi接jie影ying響xiang上shang述shu消xiao化hua酶mei的de活huo性xing，使shi仔zai兔tu消xiao化hua功gong能neng降jiang低di，發fa生sheng消xiao化hua不bu良liang而er導dao致zhi腹fu瀉xie。
