Heatstroke refers to the general term for the symptoms of body temperature regulation, water and electrolyte metabolism disorders and nervous system function damage under the long-term effects of high temperature and heat radiation.
First, the pathogenesis:
Normal body temperature remains relatively stable as a result of heat and heat balance. The summer is hot, the environment is hot and humid, and it is easy to cause the heat exchange in the pig body to lose balance. The heat dissipation mechanism is obstacled, so that the body has too much heat storage, which causes toxic effects on the cells, causing organ dysfunction and heatstroke. Failure to give rapid and powerful treatment can cause convulsions and death, permanent brain damage or kidney failure. Therefore, doing a good job in prevention and treatment of heatstroke prevention and heatstroke is an important part of ensuring the safety of pigs in summer and improving the economic benefits of pigs in summer.
Second, clinical symptoms:
Generally, pig heat stroke will show the following symptoms: 1 breathing, rapid heartbeat, irregular rhythm; 2 elevated body temperature, hot skin touch, sweating all over the body; 3 mouth foaming, unstable walking, vomiting and vomiting; 4 eyes conjunctival redness Conjunctival congestion, dilated pupils after the initial dilation, eye sputum; 5 severe convulsions, drooling, limbs do swimming-like strokes; 6 severe cases of excitement, body tremors, convulsions, collapse and death.
Third, the treatment:
If you find a heatstroke pig, you should quickly transfer the affected pig to a cool and ventilated place, apply it with cold water or apply a cold and wet towel to the head, apply it to the heart area, or spray it with cold water or a cold water bath to reduce the body temperature to 38.5~39°C. . Lowering the body temperature is the main measure for emergency treatment, and the other symptoms are relieved after the body temperature is lowered, and then the corresponding symptomatic treatment is carried out. Several methods for treating heatstroke pigs:
1, venous bleeding.
Pig body surface fever, ear congestion, can cut the tip of the ear, the tip of the bloodletting 100 ~ 200 ml, while each pig with 10 drops of water 5 ~ 10 ml orally, or intravenous injection of compound sodium chloride injection 200 ~ 500 ml .
2. Stimulation therapy.
For comatose pigs, place the right amount of ginger juice, garlic juice or a little ammonia water before placing the nose, let it inhale freely to stimulate the nasal cavity, causing sneezing and awakening. At the same time, subcutaneous injection of nikethamide (central stimulant) injection 2 ~ 4 ml.
3. Enema therapy.
For dehydrated animals, re-enemaze with normal saline or 0.5% cold saline. It can also be intraperitoneally injected with 500 ml to 1000 ml of glucose saline. One can replenish body fluids, and two can effectively reduce body temperature.
4, Western medicine therapy.
Heatstroke is severely excited and irritated pigs, each subcutaneous or intramuscular injection of sodium benzoate caffeine 0.5 ~ 2 grams. In case of excessive excitement, intramuscular injection of 2.5% chlorpromazine 3ml ~ 5ml or diazepam injection 6ml ~ 10ml. In the case of severe water loss, saline or intravenous 5% glucose physiological saline 200-500 ml.
For the treatment of heat stroke pigs, the body should first help the body to dissipate heat and cool down. According to the central nervous system, respiratory system and cardiovascular system caused by heat stroke, the corresponding symptomatic treatment should be carried out.
