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.
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
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.
