Prevention of rabbit heatstroke in high temperature season

In summer, continuous high temperature brings a series of adverse effects on the growth and breeding of rabbits. If the external temperature exceeds 33 ℃, the rabbit house temperature exceeds 30 ℃, coupled with poor ventilation, the rabbit in the cage exceeds the standard, the body heat accumulation is difficult to release, and heatstroke will occur at any time. Heatstroke is usually considered to be the cause of high heat and temperature, but it is not, muggy and unventilated, especially after the rain, humid and muggy, is the cause of the disease. Some people think that heatstroke occurs mostly at noon or in the afternoon, but the actual onset is mostly in the morning or evening, which is enough to show that heat accumulation is caused by muggy heat.

? 1. Clinical symptoms:

Rabbits suffering from heatstroke begin to slouch, raise their body temperature, eat less, feel weak, feel sleepy, and then breathe faster, the body temperature is more than 42 ℃, the mouth and nasal mucosa are flushed, and they become blue due to hypoxia, protruding eyeballs, salivation, spitting, stagnant foam and blood fluid in the nasal cavity, rapid heartbeat, and finally excited and then depressed, followed by lying on the side or abdomen, paralysis, lethargy, limb spasm, convulsions from time to time. Mouth, nose red and white foam, pupils dilated first and then narrowed, singing asphyxiation paralysis and death. Autopsy revealed lung and brain congestion, edema and peritoneal effusion. In addition, in the case of heatstroke, foamy blood from mouth and nose, which some people mistakenly think is rabbit plague, is actually caused by accelerated breathing in rabbits, resulting in telangiectasia and rupture. In the case of heatstroke, limb spasms, convulsions and cries died, mistakenly for coccidiosis, but in fact coccidiosis had no paralysis and lethargy.

? 2. Preventive measures:

The key to heatstroke lies in prevention. There are many specific measures with different effects, so we should take measures according to local conditions and make a reasonable choice.

1. Planting trees in the field and in front of the house is an advanced move, but planting vines and flowers in front of the house is improper. If you want to plant them, you should pay attention to ventilation and do not plant them too densely; splash water on the floor of the house and put wet bricks in the cage to reduce the temperature, but it should not be carried out frequently, otherwise, the humidity will lead to other diseases; the white spray on the outer wall of the house will prevent direct sunlight, not only disinfect and keep clean, but also reduce heat and cooling, killing two birds with one stone. It is also possible to install ventilator and electric fan in the house to promote air circulation, but we should beware of rabbit fever; air conditioning and wet curtain cooling, although the effect is good, but the cost is high and impractical; building an awning in front of the house and pulling the sunshade net is simple and economical.

2. Supplement melons, fruits and vegetables, provide adequate drinking water, and feed rabbits in the morning and evening, which can not prevent heat, but can only relieve heat. If the watermelon peel and cucumber taste sweet and cool, feed the rabbit some fresh and clean watermelon peel or cucumber every day, which is not only palatable, but also has the effects of antipyretic, summer heat, diuresis and thirst. Balsam pear is slightly bitter and sweet. Adding an appropriate amount of fresh Bitter Melon Juice to rabbit drinking water can effectively stimulate the secretion of saliva and gastric juice and has the functions of invigorating body, relieving thirst, relieving heat and promoting appetite.

3. Herbs can also be used to relieve summer heat, such as often picking some wild herbs to feed rabbits, which is convenient, simple and nutritious, and can also prevent the occurrence of heat sickness in rabbits. The common herbs to prevent heatstroke in rabbits are: verbena, Tripterygium, plantain, Herba Houttuyniae, Tripterygium, Tripterygium, black fern, jade leaf golden flower, shepherd scape and so on. These herbs can relieve heat and reduce the body temperature of rabbits.

? 3. Treatment:

1. When diseased rabbits are found, they should be moved to a cool and ventilated place immediately, and cold water should be applied to the head to promote the dissemination of body heat. Bloodletting between the ear vein, tail tip and four toes to reduce brain and lung congestion. Oral Huoxiang Zhengqi water, ten drops of water, warm light salt water, Rendan water, etc., remove the surface and dissolve dampness, regulate qi and middle.

2. The sick rabbit fainted and dropped garlic juice and ginger juice into the nose. Sick rabbits twitch, intramuscular injection of 2.5% chlorpromazine hydrochloride 0.5 ml, cooling and sedation. The sick rabbit is lethargic, wipe the rabbit nose with wind oil essence or drop feed, refreshing and refreshing. The diseased rabbits had dyspnea, cleared nasal mucosa, injected atropine and ephedrine intramuscularly, dilated bronchi and reduced respiratory load. When the body temperature drops and the symptoms are relieved, rehydration, cardiotonic consolidation therapy, subcutaneous or intramuscular injection of 20% sodium coffee 1 ml, rehydration, intravenous injection of glucose or sodium chloride, etc. If the conditions are not available, you can drink oral rehydration salt, VC, electrolytic multi-dimensional and so on.
