Heat stress
Regarding the summer season and increasing the temperature of the air, one of the most important problems faced by the farmers is the issue of thermal stress and its negative effects on the quality of the broiler chickens (and other laying hens and the mother). Therefore, the proper management of these conditions can be a significant contribution to reducing the problems and increasing economic returns at the end of the growing period. We will begin by defining several terms in this field:
The inadequacies of old air vents for modern air conditioned halls
As the end of the course approaches, keeping the poultry room cool and controlling the ventilation system becomes more difficult due to the weight gain of the hen. Despite the fact that for the first weeks of breeding the chicken is smaller, the air flow is 400 to 500 feet per minute, but it should naturally increase the airflow rate when approaching the loading age to cool them in hot weather conditions. . Chickens sometimes increase indoor air venting capacity by up to 50% or more, in which case the airflow rate is 600, 700 or ultimately reaches 800 ft / min.
Types of Poultry Buildings
In the past, each chicken was provided with its own initiative and with the help of a simple construction and a few construction workers for the nest to keep their chickens, but today, due to the rapid development of poultry, there are some special practices in the construction of the nest, which is the focus of attention Not only will it be used for any poultry, but also essential.
