It is easy to be poisoned by the lack of concentrate feed in winter.

There is a lack of green feed in winter, but farmers often feed concentrate feed in order to improve the growth rate of rabbits and the lactation ability of female rabbits. However, long-term intake of refined feed without sufficient grass powder will lead to severe diarrhea and death of rabbits, which should be paid attention to.

Rabbit

First, the pathogenesis:

(1) lactic acid poisoning: rabbits lack green feed, overeat concentrate feed, gastrointestinal flora imbalance, lactic acid production, gastrointestinal pH decreased. Acidosis occurs when lactic acid is too much and too fast for body fluids to exceed the metabolic capacity of rabbits.

(2) Endotoxin poisoning: rabbits overeat concentrate feed, digestive tract flora is out of balance, some pathogenic bacteria multiply in large numbers, produce a large number of toxins, causing toxic enteritis, dehydration and shock.

Second, clinical symptoms: rabbits are depressed, rough coat, loss of appetite, abdominal distension, abdominal pain, watery diarrhea, fishy stool, dry mouth, sunken eye sockets, increased drinking water, normal or slightly lower body temperature, and finally do not eat or drink until death, the course of the disease is 2-7 days.

Third, autopsy lesions: gastric mucosal swelling, hyperemia; small intestinal mucosal blood stasis; hepatomegaly; kidney stasis.

4. Treatment:

(1) to inhibit the production of lactic acid and eliminate pathogenic bacteria. Diseased rabbits stop feeding fine feed and high-quality hay. Add antibiotics to drinking water, such as gentamicin, can also be intramuscular injection of gentamicin, each 20-40, 000 units, twice a day for 2-3 days.

(2) relieving acidosis. Intravenous injection of 5-10 ml5% sodium bicarbonate injection, twice a day for 2-3 days.

(3) antitoxin and antishock. Each rabbit was intramuscularly injected with dexamethasone injection 1ml and vitamin C injection 2ml twice a day for 2-3 days.

(4) replenish body fluids and electrolytes. Intravenous or intraperitoneal injection of 30-50ml 5% glucose saline, 1-2 times a day for 2-3 days.

5. Prevention:

(1) the diet is mainly composed of green fodder and supplemented by concentrate. When there is a lack of green feed, a sufficient amount of high-quality grass powder should be added to the concentrate feed, with a dosage of up to 35%, and the amount of concentrate feed should be controlled so that it can not be overfed each time.

(2) adding 2% sodium bicarbonate to the concentrate has a certain preventive effect on rabbit poisoning.
