The issue of maintenance of proper temperature is of key importance to preserve proper condition of bred broilers.

Overheating of animals causes serious consequences:

  • reduction in the quantity of consumed feed and decrease in body weight,
  • increased water consumption,
  • increased demand for vitamins and minerals,
  • reduction in immunity and increase in susceptibility to illness,
  • reduction of droppings quality.

Temperature as a key factor in poultry breeding

The process of poultry breeding is a sophisticated issue that can be affected by many different factors. Its final result may be seriously threatened by the conditions maintained in livestock buildings including internal temperature, humidity and air quality.

In poultry breeding the issue of maintenance of the proper temperature is of key importance to preserve proper conditions of bred broilers.

Otherwise the birds are affected with thermal stress that results in lower weight gains, worse health condition and higher death rate. The level of indoor temperature in broilers’ farms should be changed adequately to the breeding stage of birds

At the beginning it should be kept on the level of 31˚C as the birds are not able to regulate their heat balance. Starting from 6th week of life the indoor temperature must not exceed 21˚C to ensure proper thermal conditions.

Broilers are very receptive to overheating effect in the 2nd stage of rearing and should be kept between 13°C and 21°C to guarantee a proper appetite and fast body mass gain. Birds need to stay in optimal thermal conditions for minimum 8 hours per day.


There are many severe consequences of exceeding the proper temperature level in broilers breeding. They typically come from the inappropriate diet that is caused by increased water consumption due to higher temperature level. At the level of ambient temperatures above 18˚C, the water consumption by older broilers is increased by 7% per each 1˚C. In the same time each 1˚C above 25˚C reduces the feed intake by 1.5 %.

Reduction of feed intake in the first place causes the lower mass gains. It also very often results in higher demands for vitamins as typically they are supplied with feed of which intake is decreased.

Additionally the worse diet quality results in bigger amount of health incidents (overheating causes immunosuppression that reduces immunity) what leads to increased death rate in each breeding cycle.

From the other hand, the overheating and increased water consumption make the birds suffered from diarrhea what results in worse quality of birds’ droppings – as these are more liquid than regular ones they cannot be used for sale.

The technical aspect of overheating

The increase of indoor temperature is related to amount of heat coming inside through external partitions of the building. The partition that is the one most exposed to the heating processes is a roof. It is strongly affected by the highest and the longest contact with direct thermal radiation of the sun. Thus the heat coming from the sun radiation is transmitted to interior parts of the buildings.

The material that creates the roof coating can have a significant impact on the amount of heat coming inside the building. The amount of transferred heat depends on two factors: ability to reflect the sun radiation (reflectance) and ability of emitting the heat back to the atmosphere (emissivity).

The higher they are, the cooler roof we have. Typically the livestock building are covered with metal sheet roofs. Metal roofs can reflect about 50% of the coming sun radiation but they are almost unable to give back the accumulated heat what means that they are very vulnerable to transfer the heat inside the buildings. Metal roofs can be heated up even up to 80˚C and that makes them the biggest heat emitters among different types of roof surfaces.


Nowadays the breeders are able to access many solutions created to solve the problem of birds’ overheating. The typical option is a roof thermal insulation that, initially created to prevent the heat from escape during wintertime, is able to reduce a certain amount of incoming heat during hot summer days.

Unfortunately, still this solution is not enough to reduce the temperature sufficiently. For that reason it is a common habit to use cooling pads that are supposed to ensure the supply of chilled air for the livestock building or fogging equipment to cool down the air with water usage. Both solutions bring wet litter due to excessive air humidity causing such problems like feet pad lesions, breast blisters and spoiled plumage.

It is always better to solve the problem at its roots. This means a solution that eliminates the problem of heat penetration through the roof structure. Here COOL-R technology comes – COOL-R is highly-reflective roof coating, the application of which combines benefits resulting from reduction in temperature inside the building and providing perfect waterproofing coating of the roof surface


COOL-R allows to reduce the temperature inside the facilities and adjust it to the required optimum, improving poultry breeding conditions and reducing its costs

COOL-R is an innovative technology, the application of which offers a unique opportunity to increase the profitability of any poultry farm, by improvement in the quality of bred animals. In this way, investment in COOL-R coating allows to increase profitability of conducted business.
