First, rabbit indigestion caused by diarrhea. More than 1 month old rabbits, the main manifestations of frequent defecation, fecal soft, atherosclerotic or watery stool.
Symptoms: Reduced appetite, loss of energy, discharge of feces, aurosis or watery stools, reluctance to walk, and loss of weight in rabbits. Severe increase in body temperature, loss of appetite; severe diarrhea, was watery, often mixed with blood or jelly-like mucus; conjunctiva cyanosis, shortness of breath, often collapsed to death.
Lesions: gas in the gastrointestinal tract, bleeding spots in the gastric serosa, diffuse catarrhal inflammation in the intestine, and fluid contents in the intestine.
Prevention: Clean up the gastrointestinal tract, regulate gastrointestinal function, sterilize diarrhea, and maintain the principle of body function prevention and control of diarrhea.
Treatment: (1) mild disease, artificial salt 2-3 grams, add water 40-50 ml orally, after the use of rhubarb Jianwei; severe, with gentamicin 4000-6000 units / kg body weight intramuscularly, 2 times a day, Use 2-3 days. (2) The diseased rabbits with less fecal odor and diarrhea can be fed with tannic acid protein, 0.5 grams each time, 2 times a day for 3 days. (3) Norfloxacin (norfloxacin) is orally administered at 20-30 mg/kg body weight once daily for 3 days. (4) In the daily feeding and management work, not feeding the feed with spoilage, not drinking dirty water, keeping the rabbit house dry and ventilated can reduce the occurrence of the disease.
Second, rabbits clostridium welchii disease. Also known as Clostridium welchiiformis enteritis, is an enterotoxemia caused by an exotoxin produced by Clostridium perfringens type A and is susceptible to 6-12 weeks of age.
Symptoms: Suddenly, the rabbit suffers from mental depression, loss of appetite, severe diarrhea, black watery or jelly-like bloody stools, unusual stench, low body temperature, severe dehydration, and most deaths of 1-2 days.
Lesions: The body is dehydrated, the abdominal cavity has rancid odor, the gastric mucosal membrane falls off, the small intestine is filled with jelly-like liquid, sometimes mixed with a lot of gas, the intestinal wall is thin and transparent, the large intestine has a large amount of gas and black water in the feces, intestinal mucosa Diffuse bleeding.
Prevention and control: prevention is the priority, and feeding and management should be strengthened. Feeds of high protein should be less fed, stress should be reduced as far as possible, and hygiene should be minimized. Introduction from infected areas is strictly prohibited and antibacterial drugs can be used for treatment.
Treatment: (1) Kanamycin 20-40 mg/kg body weight intramuscularly twice daily for 3 days. (2) Olaquindox 5 mg/kg body weight orally twice a day for 3 days. (3) Adjust gastrointestinal function, available maternal raw, tannic acid protein orally. (4) Intraperitoneal injection of 5% glucose saline 20-50 ml once daily for 2 days can improve the efficacy.
Third, rabbit rotavirus. It is a digestive tract infection caused by rotavirus and is characterized by severe diarrhea. It occurs in 2-6 weeks of age, especially in 4-6 weeks of age. It has the highest incidence of morbidity and mortality. .
Symptoms: incubation period of 1-3 days, elevated body temperature, lack of energy, severe diarrhea, semi-liquid or watery stools, brown, grayish or light green with mucus or blood, dehydration, weight loss, 2-4 days of death.
Lesions: Diffuse hemorrhage of intestinal mucosa, intestinal mucosa easy to fall off, thin content, grayish yellow or grayish black.
Prevention: The diseased rabbit should be immediately quarantined, and nursing should be strengthened to remove the rabbit feces in time. Treatment of non-specific drugs, symptomatic application of antidiarrheal agents (such as tannic acid protein), and the application of antibiotics to prevent secondary bacterial infections. The prevention of the disease mainly depends on strengthening the feeding and management, strengthening the resistance of female rabbits and puppies, and insisting on daily disinfection to kill the virus.
Fourth, rabbit salmonellosis. It is caused by Salmonella typhimurium and Salmonella enteritidis. It mainly infects pregnant female rabbits and is characterized by sepsis, acute death, diarrhea, and miscarriage. It mainly affects females over 25 days of age.
Symptoms: incubation period of 1-3 days, acute cases without any symptoms and sudden death, the majority of rabbits with diarrhea, elevated body temperature, mental depression, loss of appetite, thirst to increase, weight loss, female vaginal discharge viscosity, purulent secretion Things.
Lesions: diffuse or scattered yellow needle-shaped necrosis of the liver, gallbladder swell, bile, swelling of the spleen 1-3 times, large intestinal full of viscous feces, thinning of the intestinal wall.
Prevention: Strengthen feeding and management, enhance resistance of female rabbits, eliminate stress factors that cause the disease, and eliminate critically ill rabbits in time. For cases with lesser severity, antibiotics or antibiotics can be used for treatment.
Treatment: (1) Streptomycin 3-5 million units/kg body weight intramuscularly twice daily for 3 days. (2) Sulfamethazine 100-200 mg/kg body weight orally once daily for 3-5 days.
Symptoms: Reduced appetite, loss of energy, discharge of feces, aurosis or watery stools, reluctance to walk, and loss of weight in rabbits. Severe increase in body temperature, loss of appetite; severe diarrhea, was watery, often mixed with blood or jelly-like mucus; conjunctiva cyanosis, shortness of breath, often collapsed to death.
Lesions: gas in the gastrointestinal tract, bleeding spots in the gastric serosa, diffuse catarrhal inflammation in the intestine, and fluid contents in the intestine.

Ventilation is one of the most important components in a successful greenhouse.
If there is no proper ventilation, greenhouses and their growing plants can become prone to problems. The main purposes of ventilation are to regulate the temperature and humidity to the optimal level, and to ensure movement of air and thus prevent build-up of plant pathogens (such as Botrytis cinerea) that prefer still air conditions. Ventilation also ensures a supply of fresh air for photosynthesis and plant respiration, and may enable important pollinators to access the greenhouse crop.
