In order to increase the growth rate of rabbits and the lactating power of female rabbits, people often feed a certain amount of concentrate feed. However, when rabbits feed on concentrates for a long period of time and there is no adequate amount of grass powder in the concentrate, they often cause severe diarrhea in a large number of rabbits, which should attract the attention of the rabbit owners.
1 Pathogenesis
1.1 Lactic acidosis in rabbits lacks green fodder for dietary concentrates. The gastrointestinal microbial flora is dysregulated, producing lactic acid, and the gastrointestinal pH value is reduced. When lactic acid enters the body fluid too quickly and exceeds the metabolic capacity of the body, it causes acidosis.
1.2 Endotoxin-poored rabbits have dietary supplements, dysregulation of the microbial flora of the digestive tract, and the proliferation of some pathogenic bacteria, resulting in a large number of endotoxins, causing toxic enteritis, dehydration, and shock in rabbits.
The rabbit is depressed in spirit, rough hair, loss of appetite, bloating, abdominal pain, watery diarrhea, stinky stool, dry mouth, sunken eye sockets, increased drinking water, normal or slightly lower body temperature, and finally eating or drinking until death, duration 2 -7 days.
3 necropsy
Gastric mucosal swelling, congestion; small intestinal mucosal bleeding; hepatomegaly; renal blood stasis.
4 treatment
4.1 Inhibit lactic acid production and eliminate pathogens Rabbits stop feeding concentrates and feed quality hay. Drinking water to add antibiotics, such as gentamicin, can also be injected intramuscularly with gentamycin, 20,000-40,000 units each, 2 times a day for 2-3 days.
4.2 Relieve acidosis 5% sodium bicarbonate injection 5-10ml, intravenously, 2 times a day for 2-3 days.
4.3 anti-toxin, anti-shock Each rabbit intramuscular injection of dexamethasone injection 1ml, vitamin C injection 2ml, 2 times a day for 2-3 days.
4.4 Add body fluids and electrolytes by intravenous injection or intraperitoneal injection of 5% glucose saline 30-50ml, 1-2 times a day for 2-3 days.
5 Prevention
5.1 Diets are dominated by green feed, supplemented by concentrate feed. When there is a lack of green fodder in winter, a sufficient quantity of high-quality grass powder should be added to the concentrated feed, and the amount can reach 35%, and it is necessary to control the feed amount of the concentrate and not feed it at a time.
5.2 The addition of 2% sodium bicarbonate to the concentrate will have a preventive effect on the occurrence of this disease.
