The material that creates the roof coating can have a significant impact on the amount of heat coming inside the building. Thus the heat coming from the sun radiation is transmitted to interior parts of the buildings. It is strongly affected by the highest and the longest contact with direct thermal radiation of the sun. The partition that is the one most exposed to the heating processes is a roof. The increase of indoor temperature is related to amount of heat coming inside through external partitions of the building. It also very often results in higher demands for vitamins as typically they are supplied with feed of which intake is decreased.Īdditionally 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.įrom 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. Reduction of feed intake in the first place causes the lower mass gains. ![]() In the same time each 1˚C above 25˚C reduces the feed intake by 1.5 %. At the level of ambient temperatures above 18˚C, the water consumption by older broilers is increased by 7% per each 1˚C. They typically come from the inappropriate diet that is caused by increased water consumption due to higher temperature level. There are many severe consequences of exceeding the proper temperature level in broilers breeding. Birds need to stay in optimal thermal conditions for minimum 8 hours per day. Broilers are very receptive to overheating effect in the 2nd stage of rearing and should be kept between 13☌ and 21☌ to guarantee a proper appetite and fast body mass gain. Starting from 6 th week of life the indoor temperature must not exceed 21˚C to ensure proper thermal conditions. At the beginning it should be kept on the level of 31˚C as the birds are not able to regulate their heat balance. The level of indoor temperature in broilers’ farms should be changed adequately to the breeding stage of birds. Otherwise the birds are affected with thermal stress that results in lower weight gains, worse health condition and higher death rate. In poultry breeding the issue of maintenance of the proper temperature is of key importance to preserve proper conditions of bred broilers. ![]() ![]() Its final result may be seriously threatened by the conditions maintained in livestock buildings including internal temperature, humidity and air quality. The process of poultry breeding is a sophisticated issue that can be affected by many different factors.
