母兔日粮中缺乏蛋白质、矿物质(如：钙、磷、硒、锌、铜、铁等)、维生素，尤其是缺乏胡萝卜素和VE 时，容易导致胎儿发育终止，引起流产，产出弱胎、软胎或僵胎。 据分析饲料搭配不当，过于单一，营养价值不全，营养不良等原因造成的。
Mother rabbit diets deficient in protein, minerals (such as calcium, phosphorus, selenium, zinc, copper, iron, etc.), especially the lack of vitamins, carotenoids and VE, easily lead to fetal development and termination, cause abortion, weak fetus, fetal output soft or stiff tyre. According to analysis, improper feed collocation, too single, poor nutritional value, malnutrition and other reasons.
维生素和矿物质缺乏时，妊娠母体对生活环境的适应性及对疾病的抵抗力降低，也会引起死胎流产。维生素A 缺乏时，对上皮组织机能失去促进
When vitamins and minerals are scarce, the adaptation of the mother to the living environment and the resistance to disease can also lead to stillbirth and miscarriage. When vitamin A deficiency occurs, it can not promote the function of epithelial tissue
作用，往往导致子宫粘膜和绒毛膜的上皮细胞角质化、脱落，使胎盘的机能缺乏“粘合性”，胎膜容易脱离，造成死胎。维生素E 缺乏时，胚胎发育
The function often leads to the keratinization and shedding of epithelial cells in the mucous membrane and chorion of the uterus, resulting in the lack of adhesion of the placenta and the easy separation of fetal membranes, resulting in stillbirth. Embryonic development during vitamin E deficiency
初期即死亡，被兔吸收，俗称“化崽”。妊娠后期缺乏维生素E 时易早产。
Early death, absorbed by rabbits, commonly known as "pups"". Late pregnancy vitamin E deficiency prone to premature delivery.
矿物质钙、磷缺少或微量元素硒、锌、铜、铁缺乏时，胎儿营养补给不足，引起胎儿发育中断或产弱胎和畸形胎。所以提醒大家在养殖的过程的兔饲料的选择是关键，不容忽视。
Lack of mineral calcium or phosphorus, or trace elements selenium, zinc, copper, iron deficiency, lack of nutritional supply of the fetus, cause fetal development interrupted or weak birth and deformed fetus. So remind everybody, in the process of breeding rabbit feed choice is the key, can not be ignored.
