1. Etiology

当母兔体内的胎儿快速生长发育，对营养需求旺盛，而此时由于妊娠反应，子宫及其内容物（胎儿）快速扩增而压迫胃肠，影响消化系统的运动和功能，造成采食量降低，形成了营养需求和营养摄入的巨大反差。这种入不敷出的局面导致母体不得不分解自身体内脂肪来维持胎儿的发育和妊娠的持续。当母体脂肪分解的中间代谢产物酮体（乙酰乙酸、β-羟基丁酸及丙酮）的产生量大大超过利用能力的时候，造成这些酸性物质在体内的大量积聚而导致中毒。

When the fetus in the female rabbit grows and develops rapidly and has strong demand for nutrition, due to pregnancy reaction, The rapid expansion of the uterus and its contents (fetus) oppresses the gastrointestinal tract, affects the movement and function of the digestive system, reduces food intake, and forms a huge contrast between nutritional demand and nutritional intake. This situation of making ends meet leads to the mother having to decompose her own body fat to maintain the development of the fetus and the continuation of pregnancy. When the intermediate metabolite ketone body of the mother's fat decomposition (acetoacetic acid β- When the production of hydroxybutyric acid and acetone) greatly exceeds the utilization capacity, these acidic substances accumulate in the body and lead to poisoning.

2、症状

2. Symptoms

食欲减退或废绝，精神出现短期的兴奋，后转为抑制，头低沉，反射迟钝，精神委顿，步态蹒跚。有的后期颇似产后瘫痪，常发生昏迷状态。呼出的气体和排出的尿液有酮酸味道。一般在产前或产中死亡。即便没有死亡，产后无乳，停食，失去饲养价值。妊娠毒血症近年来在一些兔场频发，其一般规律为母兔过于肥胖或偏瘦，饲养管理不当，饲料内蛋白、脂肪过剩，糖类和维生素不足，所怀的胎儿较多的情况。

Loss of appetite or abandonment, short-term excitement in the spirit, and then turn to inhibition, low head, slow reflex, mental fatigue and staggering gait. Some later stage is quite like postpartum paralysis, often in a coma. Exhaled gas and excreted urine smell of ketoacids. Usually die before or during childbirth. Even if there is no death, there is no milk after delivery, no food, and lose feeding value. Pregnancy toxemia has occurred frequently in some rabbit farms in recent years. The general law is that the female rabbits are too fat or thin, improper feeding and management, excess protein and fat in the feed, lack of sugar and vitamins, and have more fetuses.

Prevention and treatment of rabbit disease: Rabbit pregnancy toxemia

3、防治

3. Prevention

应该从多方面入手。，在妊娠后期，控制饲料中蛋白质含量，适当添加葡萄糖，添加1%的小苏打；其次，当母兔食欲不振，采食量降低时，可降低精饲料喂量，给予适口性较好的青饲料，放出去活动，以增进采食量；第三，国内外相关研究表明，在母兔的后备期间，降低饲料营养浓度，提高粗纤维含量，以增加采食量，促进胃肠的发育，有助于预防妊娠毒血症；第四，当出现妊娠毒血症轻度症状时，可静脉注射高糖（25%～50%葡萄糖）50毫升，口服5%的碳酸氢钠20毫升，皮下注射复合维生素B。

We should start from many aspects. First, in the later stage of pregnancy, control the protein content in the feed, add glucose appropriately and 1% baking soda; Secondly, when the female rabbit has a poor appetite and the feed intake decreases, the feed intake of concentrate can be reduced, green feed with good palatability can be given, and put out for activities to increase the feed intake; Third, relevant studies at home and abroad show that during the reserve period of female rabbits, reducing feed nutrient concentration and increasing crude fiber content can increase feed intake, promote gastrointestinal development and help to prevent pregnancy toxemia; Fourth, when mild symptoms of pregnancy toxemia occur, 50 ml of high glucose (25% ~ 50% glucose) can be injected intravenously, 20 ml of 5% sodium bicarbonate can be taken orally, and compound vitamin B can be injected subcutaneously.
