First, the environment includes air, so the first choice is air circulation management
The ventilation of the chicken greenhouse is divided into natural ventilation and mechanical ventilation.
When designing the ventilation system, not only the breeding density of laying hens and the local maximum temperature should be taken into account, but also the uniform ventilation should be paid attention to. The required ventilation should be estimated by referring to the standard ventilation volume of each chicken and the number of breeding birds, and then the number of fans to be equipped should be calculated according to the performance of the fans to be installed and used.
For natural ventilation, windows are used under the action of natural wind and temperature difference. The total area of windows (in North China) is usually about 1/3 of the building area.
In order to better ventilate the chicken shed evenly, the windows should be balanced and evenly distributed.
In order to better regulate the ventilation volume, the windows can also be made into two rows, and part of the windows can be opened and closed according to the ventilation volume regulations, which can use both the natural wind force and the ventilation effect of temperature difference.
In winter, in order to better prevent the cold wind from blowing directly to the chicken, the wind deflector can also be installed and used, so that the wind speed can be reduced and evenly enter the chicken shed.
The ideal window structure is divided into three layers. The inner layer is made of wire mesh, which is conducive to preventing wild birds from entering the house and animal damage. The middle layer is a glass window frame, and the outer layer is made of plastic film, which is mainly used for winter insulation.
Mechanical ventilation is the main method to regulate the environmental conditions in the closed chicken greenhouse, high density of laying hens and large group breeding conditions. Ventilation is closely related to temperature control, humidity control, dust removal and air conditioning.
The mechanical ventilation methods of the enclosed chicken greenhouse in the contemporary era mainly include two kinds, namely, horizontal ventilation and vertical ventilation. These two ventilation methods have their own advantages and disadvantages. In the design of the chicken greenhouse, appropriate methods can be selected according to the actual situation. Reasonable ventilation, the temperature may be very high, the density may be high, the temperature is high, the humidity is high, the window can be opened wide, and even the exhaust fan can be opened. Exhaust. If the temperature drops suddenly at night, the exhaust fan can be turned off for natural ventilation. As the case may be,
Second, chicken manure must be cleaned and washed regularly in time. In high temperature weather in summer, harmful gases from livestock and poultry manure will be released more quickly, and mosquitoes and flies will breed.
Third, disinfect the premises and equipment regularly. The buildings can be sterilized by electric spray, and the equipment drinking water pipeline can be regularly cleaned by adding drugs.
We will strengthen disease prevention and control and environmental sanitation and disinfection. Clean and disinfect the environment in the house and field regularly to ensure a clean and pestile-free breeding environment.
Fourth, when the weather is hot, it is necessary to supplement the chicken with VC or complex vitamins and drink more water. You can pour multidimensional liquid into the water tank for the poultry to drink, supplement nutrition and resist stress, and improve their vitality. Make them healthier and increase their tolerance to hot environment. It will not affect egg production due to mental depression and poor appetite.
It is recommended to use liquid multi-dimensional nutrition supplement, which is more uniform for individual supplement, good absorption and high utilization rate.
