Closed greenhouse system (evaporative cooling system) because Thailand is a country in the tropics with relatively high air temperatures. Most animal farmers tend to build open houses. This is in order to allow the air inside the house to be circulated and ventilated, which is a good way to reduce heat inside the house. Open greenhouses cannot control the temperature. The temperature of the greenhouse will vary according to the weather conditions outside the greenhouse. During the summer, the weather is very hot. Some pets, such as broilers, may not be able to tolerate the hot weather. To avoid hot weather and to control the temperature of the greenhouse, a closed greenhouse system was invented using the principle of water cooling and using a fan as the air circulator. It has a honeycomb pad (cooling pad) that lets water flow through until it is soaked. When running the fan which is in opposite direction to the honeycomb panel, outside air will be sucked through the honeycomb panel into the house. The inside of the greenhouse will be cool using the principle of water evaporation. In addition, closed greenhouses can prevent disease very well, especially bird flu. Both open greenhouses and closed greenhouses have different advantages and disadvantages. Animal owners must decide which housing system they should use, but overall, closed housing systems help solve the problem of hot weather. and prevent disease better than open greenhouses The advantages and considerations of a closed system house are as follows: Advantages: Reduces stress caused by heat and makes chickens healthier. In parents - broiler chicken breeds will have higher production. Reduce death rate Especially during very hot weather. They use fewer fans compared to open schools. and is economical Electrical charge Can be used in conjunction with a dark-out system to raise male and female chickens more efficiently than open houses. The air circulation within the house is very regular. Fresh air from outside will pass through the honeycomb panels into the house and exhaust air outside the house using a fan for only a short time, reducing the problem of ammonia levels in the house. Better growth rates and good feed conversion efficiency in broiler chickens Reduce the use of antibiotics Can house more chickens than open houses Compared to the same area […]
