With the temperature and humidity meter, the chicken to the healthy growth

The effect of temperature on the chicken, the temperature had the greatest influence on chicken production performance. Chicks resistance is poorer, the requirement of temperature is higher, at the same time, appropriate temperature is the assurance of chicken play normal production performance. If temperature is higher, the chicken feed intake down, feed conversion rate decreased, chicken egg egg weight reduce weight slows, eggshell quality, laying rate drop dead rise until a large number of hot dead chicken. And the low temperature will increase in the number of maintaining need make chicken, slow growth, increased material egg ratio and feed conversion ratio. Winter low temperature and excessive temperature fluctuations in the henhouse, can make chicken resistance drops, laying down chickens induced respiratory disease until the moult, therefore the temperature is prompted a cold heat stress affects chickens poultry health and performance of the primary environmental factor. A, high temperature influence on chicken chicken is warm-blooded, through producing heat and heat to maintain a constant temperature. Under the condition of high density of intensive breeding, chicken metabolic heat production increases with the increase of growth rate, and heat capacity did not improve. Chicken chicken age, formulates different and change, a few weeks before the chicks in very strict with temperature of whether to use a local heating of the heat preservation umbrella or use of the hen house heating, the temperature of the chicks area must be guaranteed. For the layer chicken, is the most suitable temperature 18 ℃ - 23 ℃, under the appropriate temperature, layer chicken performance for high disease resistance, feed utilization rate is high, has high economic benefit. Chicken in a warm area or below this range, mainly through the form of evaporation cooling heat dissipation, when under the condition of high temperature of evaporation cooling effect has much more subdued, as a result of the limitation of chicken feathers cover and a lack of sweat glands chicken hypothermia and the only way is through the respiratory evaporative heat dissipation heat away, however, increased breathing rate is added to the heat so only part of the heat dissipation effect. Second, the low temperature impact on chicken low temperature will increase the maintain of chicken needs first, the chicken feed conversion ratio by chicken laying rate drop, chicken's ability to fight disease. Winter henhouse at low temperature, in order to keep temperature and there is no guarantee the required ventilation, temperature and ventilation management imbalances in winter in the henhouse ammonia concentration of the harmful gas such as increasing environmental degradation, in the henhouse under the condition of large temperature difference especially when the outside temperature shock, heating or ventilation is not very good with excessive temperature fluctuations in the henhouse, when the temperature suddenly drops can cause cold stress in production performance at the same time also can cause the occurrence of respiratory diseases such as chickens. Third, the application of air cooling effect under the condition of the air flow, chicken feel temperature and real temperature of effective temperature and measurement is different, sometimes feel Sherwin vary widely, even feel the cool wind speed, the greater the chickens this is air cooling effect. By experimental determination, the environment of high temperature, the air is beneficial to form the convection. When the temperature in 24 ℃ - 47-33 ℃, relative humidity 62% of the climate, wind speed by 1. 1 m/s to 1. 6 m/s rate can have certain enhancement. In the absence of the wind or the low wind speed, Less than zero. 3 m/s) Body feeling temperature, chicken is equal to the ambient temperature, when the wind speed is greater than zero. 5 m/s body feeling temperature when the chicken will be reduced. So the effect of water cooling during the summer should make full use of air cooling, and winter should try to reduce the influence of air cooling effect to chickens. A temperature and humidity meter is placed in the hen house, can not only measure temperature, and can measure the humidity, ensure the healthy growth of the chickens.
