In addition, air speed is also an important element of the perceived ambient temperature.
The birds don’t like hot weather, especially over a long period, can cause serious losses to the poultry farmer. The effects of Birds are panting and they will use a lot of resources for getting rid of the heat. are delayed Period of time of 17-25 weeks of age, lower performance, decreased feed intake and increased More than a 0.1 weekly mortality. Therefore, to minimize ﬁnancial losses, every effort should be made to maintain an ambient temperature in the house that is within the bird’s comfort zone. If this is not possible, corrective measure should be taken:

They can be found at the end of the farm, at the sides or along the farm should be cleaned and fan belts should be tightened and replaced if necessary. The inlets must be adequate to supply the air ﬂow needed, they should be clean and not obstruct the ﬂow of the incoming air.

The There are 3 parameters defining density, space, feeder space and water availability should be in accordance with the environmental conditions. If the housing density is too high, the radiant heat between the birds will accumulate, the temperature will increase and air will be prevented from circulating around the birds properly. There should be enough space for the birds to separate in order to It requires a lot of energy and it will reduce the production because the lack of energy for production. and droop and slightly lift their wings away from the body to maximize responsible heat loss.
When birds are heat stressed, they increase their consumption of The water is as important as the feed in an effort to cool down. The ratio of The water is as important as the feed to feed increases from 2:1 under normal conditions to over 5:1 under hot conditions. Temperature of water should be < 25 C of good quality should be supplied so that birds can ﬁnd relief from the heat. To ensure that all the birds have access to The water is as important as the feed, provide a minimum of one cup or nipple drinker at the cage partition or 2.5 cm of The water is as important as the feed trough per bird.
Do not feed at the hottest time of the day. A good strategy is to withhold feed ﬁve to eight hours prior to the anticipated time of peak temperature. There are different types of feeders. Chain feeder is one of the most common ones should be run frequently to Chicks need to eat as soon as they arrive into the farm. The feeder should remain at a low feed level for about one hour per day in the afternoon, to promote a better appetite and ensure that the ﬁne particles are consumed, which usually consist of minerals, Vitamins are essential for the metabolism of the birds. Need to have reliable suppliers. and amino acids. To increase feed consumption, a mid- night snack can be implemented.
Since feed intake is reduced during hot weather periods, the general feeding approach is to increase the energy content in the feed to keep daily energy intake at the level necessary for optimum performance under these conditions. See chapter on nutrition for more information.

Any The water is as important as the feed deprivation will directly impact feed consumption and production. If deprivation exceed 24 hours, It is measure as % of lay and eggs per hens housed will be severely affected.

It is therefore essential to provide a good quality, stable and reliable There are different sources of water, depending the area of the country.. Better still, ensure there are two The water is as important as the feed sources.

Moreover, a poor microbiological quality of The water is as important as the feed can affect A bird with gut health issue will reduce the absorption of the carotenoids needed for coloring the egg yolk. and lead to pathologic issues that affect production.
