Broiler poultry farm Management
Broiler Poultry Breeding and Management
Behavior of 1 day old chicks( Broiler chicken )： we should inspect the chicks behavior at day and night every one hour . .
1. if chickens distributed evenly in the poultry shed, operating temperature and ventilation set up is correct;
2. if Chickens clumped together in a certain area, slow, look very puzzled, shows that the temperature is too low;
3. Chicken always avoid through an area, there are evil wind;Open chicken wings on the ground, 4. chicken look in the pant and chirp, means high temperature or high co2 concentration.
A. Light Lower temperature welcoming the DOC broiler babay chicks
Chickens after a long period of transport, hunger, thirst, physical conditions are more weak. In order to allow chicks to adapt quickly to the new environment and return to normal physiological conditions, we can slightly lower the temperature of the broiler shed on the basis of brooding temperature, keeping the temperature in the hive fence between 27 and 29 ° C, so that chicks can gradually adapt The new environment for the future growth of the normal lay the foundation.
The broielr chicks need to adapt to the new environment, this time chicks rest is normal, but 4 to 6 hours later, chicks should begin to spread in the chicken shed , and began to free water, feeding, walking, 24 hours later Spread in the chicken shed evenly.
B. suitable temperature for broiler poultry breeding /farming
Chicks dwell after 24 hours, if still get together, may be due to the temperature inside the house is too low. When the temperature inside the house is too low, if the litter and air temperature heating, will lead to poor chicken development and chicken uniformity is poor. Chicks get together will make the temperature is too high, chicks arrive at the brook after they should be immediately spread out, while maintaining the appropriate temperature and dim light.
The temperature is appropriate, not by the breeder's own comfort or not to judge, nor can only refer to the thermometer, the chicks should observe the individual performance. When the temperature is appropriate, the chicks are evenly scattered in the brooding room, the spirit of lively, good appetite, moderate drinking water.
When the temperature is appropriate, the flock is evenly distributed, the food is orderly, there is a lying activity, the horizontal is also more comfortable; the temperature is high, the flock hides at the fence, but the horizontal is also good, only the temperature is slightly High, flocks can adapt, but want to stay away from heat. If the temperature is high, the flock is no longer lying, there will be mouth breathing, wings drooping situation.
C. Ensure proper relative humidity of broiler poutry shed
Chicks into the brooding house, you must maintain the appropriate relative humidity, at least 55%. Cold season, when the amount of polonium heating, if necessary, you can install the heating nozzle, or in the aisle spilled some water, the effect of Wu better.
4 ventilation of Chicken House
The climate inside the house depends on the combination of dry ventilation, heating and cooling. The choice of ventilation system should also be adapted to external conditions. Whether the ventilation system is simple or complex, it must be manipulated first. Even the automatic ventilation system, the management of the eyes, ears, nose, skin feeling is also an important reference.
Natural ventilation does not use fans to promote air flow. Fresh air through the open air inlet into the chicken coop, such as adjustable inlet valve, shutter. Natural ventilation is simple, low cost ventilation.
Even in areas where natural ventilation is good, farm owners are increasingly choosing mechanical ventilation. Although the hardware investment and operating costs are higher, but the mechanical ventilation can better control the environment within the house, and bring better breeding results. Through the way of negative pressure ventilation, the air from the inlet into the chicken coop, and then forced out of the house. The effect of mechanical ventilation depends on the control of the air inlet. If there is an open loophole on the side wall of the house, it will affect the operation of the ventilation system.
To timely evaluate the ventilation effect. For the ground level system, the distribution of flocks in the chicken coop can explain the effect and quality of ventilation, but also through other methods to assess the ventilation effect. The simple way is to bare and wet the arms, stand to the chicken gathered a small number of areas, feeling whether the region has a thief wind, feel the litter is too cold. Observe the distribution of flocks in the whole house, and determine whether it is related to the setting of the fan, the light and the air inlet. Once changed the lighting, air intake and other equipment settings, after a few hours to observe whether the distribution of flocks have changed. For changing the effect of setting, do not easily deny the conclusion. Also record the contents of the change settings.
Ventilation settings are not only dependent on the temperature, but also need to consider the humidity of the chicken coop, as well as the height of the wind back to the chicken and the air in the high concentration of carbon dioxide. If the concentration of carbon dioxide is too high, the chicken will become lethargy. If you have a headache after more than 5 minutes of continuous work at the height of the chickens, the concentration of carbon dioxide is at least 3 500 mg / m3 indicating that the ventilation is not enough. Also note that there can be no thief wind.
