1. Etiology

當母兔體內的胎兒快速生長發育，對營養需求旺盛，而此時由于妊娠反應，子宮及其內容物（胎兒）快速擴增而壓迫胃腸，影響消化系統的運動和功能，造成采食量降低，形成了營養需求和營養攝入的巨大反差。這種入不敷出的局面導致母體不得不分解自身體內脂肪來維持胎兒的發育和妊娠的持續。當母體脂肪分解的中間代謝產物酮體（乙酰乙酸、β-羥基丁酸及丙酮）的產生量大大超過利用能力的時候，造成這些酸性物質在體內的大量積聚而導致中毒。

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、癥狀

2. Symptoms

食欲減退或廢絕，精神出現短期的興奮，后轉為抑制，頭低沉，反射遲鈍，精神委頓，步態蹣跚。有的后期頗似產后癱瘓，常發生昏迷狀態。呼出的氣體和排出的尿液有酮酸味道。一般在產前或產中死亡。即便沒有死亡，產后無乳，停食，失去飼養價值。妊娠毒血癥近年來在一些兔場頻發，其一般規律為母兔過于肥胖或偏瘦，飼養管理不當，飼料內蛋白、脂肪過剩，糖類和維生素不足，所懷的胎兒較多的情況。

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.

3、防治

3. Prevention

應該從多方面入手。，在妊娠后期，控制飼料中蛋白質含量，適當添加葡萄糖，添加1%的小蘇打；其次，當母兔食欲不振，采食量降低時，可降低精飼料喂量，給予適口性較好的青飼料，放出去活動，以增進采食量；第三，國內外相關研究表明，在母兔的后備期間，降低飼料營養濃度，提高粗纖維含量，以增加采食量，促進胃腸的發育，有助于預防妊娠毒血癥；第四，當出現妊娠毒血癥輕度癥狀時，可靜脈注射高糖（25%～50%葡萄糖）50毫升，口服5%的碳酸氫鈉20毫升，皮下注射復合維生素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.
