Popis: It was studied the effect of heat stress on productive capacity at ROSS 308 female parents exposed to temperatures of 32-37°C during the day. The hens were reared on the floor, in intensive system. The experimental period was of 3 weeks. The following parameters were monitored: The following parameters were monitored: egg production, egg weight, egg mass, feed intake, specific number of incubated eggs. The egg production, intake and incubated eggs were recorded daily; egg weight and egg shell thickness weekly. The productive parameters were significantly influenced by exposure to warm temperature (p≤0.05). It was observed a significant decrease in egg production and feed consumption and a high percentage of cracked eggs, which can not be utilized for incubation. The number of incubated eggs was reduced by 37%.
