Due to the high temperature and hot weather in summer, the tolerance of pigs to heat is poor. If the feeding management is not good, it will easily lead to heatstroke. Mainly in two aspects: one is the heat radiation caused by the humid and humid environment; the second is the sunstroke that occurs under the sun for a long time.
First, the cause of heat stroke in summer pigs
There are many factors in summer heatstroke in pigs: (1) insufficient ventilation in pig houses; (2) too many pigs in stock; (3) too little drinking water in pigs; (4) unsanitary housing; (5) unscientific construction of pig houses There is no shed on the top of the event.
Second, the clinical symptoms of summer pig heat stroke
Sudden onset, breathing, rapid heartbeat, elevated body temperature, corneal congestion, foaming at the mouth, restlessness, sweating, dilated pupils, unconsciousness, unsteady walking, lying down, often due to lack of treatment The heart is weak and soon dies. The lighter is given appropriate treatment at the beginning of the disease and can be cured within 1 to 2 days.
Third, measures to prevent pigs from heatstroke in summer
(1) A scientific and standardized pig house should be built, and the window should be kept around;
(2) The live pigs in the circle should not be too much, and the density should be rationalized;
(3) To provide enough clean drinking water, salt should be added in appropriate amount. Regularly feed the pigs with watermelon, mung bean soup and other cooling and heat-preventing materials;
(4) The pig house should be cleaned and cleaned properly. The pool should be changed frequently to allow it to bathe freely;
(5) Set up the pergola. If it is a thermostatic pig house, in addition to covering the gauze and anti-mosquito, you should also put a pergola above the pig activity field. If there are grape, loofah, gourd and other vine plants on the shelf, the heatstroke effect is better.
Fourth, summer heat treatment measures for pigs and pigs
When the pig has heatstroke, the pig house should be ventilated as soon as possible, or the pig should be transferred to a cool place, and the head and chest should be poured with cold water. If necessary, 0.5 to 1% of cold salt water can be used for repeated enema. 10% of Anaga 12-20 ml, add 5% sugar salt 255 ~ 500 ml ear injection: those with nerves, restlessness, 3 to 5 with 2 ml of stability needle (or 2.5% chloropropyl Intramuscular injection of 3 to 5 ml of azine (a dose of 50 kg body weight)
