Effective temperature regulation is one of the most important success factors when it comes to egg production in the Philippines. For good production, you should maintain temperatures in the range of 11 to 26 degrees Celsius. 25 degrees Celsius should be the peak temperatures to be maintained in the layer house.
With colder temperatures in the poultry house after the peak has been achieved, there will be a rise in the feed intake and will also have a negative impact on the egg weight control, the optimal feed efficiency of your poultry egg production operation as well as the body weights of the adult hens. In an earlier post, we stated that the layer chickens should have a weight of about 1.5Kg for optimal egg production.
If possible, it is advisable to put temperature sensors inside the poultry house so that you can closely monitor the ambient temperatures inside. Higher ambient temperatures will have an adverse effect on the feed intake inside the poultry house. Here is a look at the effect of temperature change in your layer farming operations in the Philippines:-
11-26 degrees Celsius: Optimal production
26-28 degrees Celsius: There is a little reduction in the feed intake
28-32 degrees Celsius: The feed consumption is reduced and the level of water intake is increased in the poultry house. The eggs produced are of reduced size and have thinner egg shells.
32-35 degrees Celsius: There is slight panting. Further reduction in the feed intake.
35-40 degree Celsius: The chickens begin to suffer from heat prostration. You must take quick measures in order to cool the poultry house.
Over 40 degrees Celsius: The chickens suffer from heat stress and begin to die.
Whenever there is a temperature rise beyond 28 degrees Celsius, there will be a decrease in production as well as in the quality of the eggs. Seasonal temperature changes in a country like Philippines can result in up to 10 percent decrease in egg production.
