With the continuous improvement of the intensive degree of layer chicken cage breeding, the scale of breeding becomes larger and larger. Chicken farming has entered the stage of meager profit, competition continues to intensify, and the requirements for product quality are constantly improving. The unit benefit of each chicken is already very small, which requires us to strive for excellence in management.
At present, most diseases are closely related to the control of the chicken house environment, which means that the control of the chicken house environment plays a vital role in the control of chicken diseases. The average weekly dead scouring of chicken houses with good environmental control can be significantly reduced compared to conventional chicken houses. Strengthening environmental control significantly reduces the overall dead scouring of the chicken flocks and also reduces the incidence of environmental diseases.
1. The cooling effect under different humidity conditions in summer
In addition to strengthening the ventilation of the chicken house in summer, other heatstroke prevention and cooling measures must be taken. After continuous exploration and practice, there are many measures to solve the heatstroke prevention and cooling of the chicken house, all of which have a certain effect of heatstroke prevention and cooling, but practice has proved that the water curtain evaporation and cooling is the most effective way to control the temperature of the chicken house in summer.
2. Minimum ventilation setting in winter
While paying attention to heat preservation in the chicken house in winter, in order to ensure the normal environmental conditions in the chicken house, the exhaust air cannot be completely closed when the house temperature is lower than the set temperature. Instead, the minimum ventilation of the chicken house under the control of a timer should be used, but the following four necessary conditions should be met when using the minimum ventilation. Enclosed, insulated, no air leakage chicken house. The cold air outside the house cannot be blown directly to the chicken body. Determine the correct ventilation rate according to the age of the flock. The ventilation switch is controlled by a five-minute timer, or a complete switch cycle is controlled by a controller not longer than five minutes, with an accuracy of less than 1 minute.
3. Ventilation settings in spring and autumn
The design of a good environment control chicken house should be able to meet the needs of chicken house environment control in different seasons. The setting and control of the ventilation system should use different modes in different seasons. Longitudinal ventilation with water curtain cooling is used in the hot summer season, and the temperature in the house is well cooled. In winter, in order to ensure proper ventilation and uniform temperature in the house, horizontal ventilation mode and "minimum" ventilation should be adopted.
The opening size of the air inlet at the water curtain, side wall air inlet, and the number of running fans can be adjusted at any time. In order to more timely and accurately implement the conversion and adjust the size of the air inlet and the opening number of the exhaust fan, a computer should be used for automatic conversion control. Although better results can be achieved under correct manual conversion and use, in actual operation, if the manual control conversion is not timely or improperly used, it will have a great impact on the environment of the chicken house.
In the process of raising chickens, various problems will be encountered. Many problems can be avoided when using chicken battery cages to raise chickens. Therefore, more and more farmers have begun to use poultry farming equipment to raise chickens, which is convenient and fast, and saves manpower.
