Due to the influence of external environmental factors, resulting in a sharp increase in temperature in chicken physiological disorder occurring in an overheated disease. Chicken without sweat glands, have a relatively high temperature deep, its body covered with feathers, can produce very good insulation effect, mainly by respiratory heat and regulate body temperature, if the ambient temperature, high humidity, lack of drinking water, especially ventilation and poor, the chicken body cooling difficulties, very prone to heat stress, resulting in chicken metabolism and physiological disorders, thereby affecting the health of chickens, even death, to bring some economic losses to the poultry production. First, the disease characteristics of a chicken heatstroke, sunstroke laying prone to defect excess 32 ℃ ventilation, poor sanitation coop. The severity of heat stroke with Sherwin increased and increased, when the house temperature exceeds 39 ℃, the hens can quickly lead to heat stroke caused by a large number of deaths. 2, breeders, particularly broiler breeder low tolerance to high temperature, heat stroke when the chicken looks athletic, body fatter chickens are often the first to die. Laying flocks in high yield, this situation can easily occur. 3, 7-9 at night is the peak time heatstroke death of chickens. Summer day, 10:00 to 17:00 of Sherwin is persistently elevated, particularly sensitive to heat chicken, the afternoon 5-6 points its thermoregulatory function has been to the limit, then the temperature has risen to thermal shock The critical temperature (45.3 ℃), if not take immediate measures to make the chicken quickly from the hot environment, so most laying hens will be shock and death in the evening 7-9 points. Second, control measures are currently no effective treatment, but can be adjusted using drugs or artificially created conditions to improve the production environment, lowering the temperature, can reduce the degree of heat stress response. 1 outside the house to create a suitable environment to enhance ventilation 2 3 4 artificial cooling to reduce thermal stress added extra stress 5 drugs in feed --- Icy vc. Its main ingredient is mint and borneol, can effectively prevent heat stress symptoms. Order Tel: 15838306900.QQ: 927615390 .. Contact, Liang Qi. 5 cool enough for water
