Resumen
The State University of Maringa (UEM), in the Experimental Hacienda of Iguatemi, implemented fans and nebulizers for temperature control in two commercial layer sheds, with identical dimensions (50 cm wide × 42 cm high × 45 cm bottom), line-type feeders and nipple-type feeders (one / cage), transporting eggs mechanically once a day between 8 a.m. and 9:00 a.m. The removal of chicken manure was done with shovels and wheelbarrows. We evaluated 500 birds of 44 weeks per shed of line Hy line w 36, belonging to the same lot coming from the incubator of the integrator. The duration of the test was 9 weeks and temperature and relative humidity of the air were measured by sensors programmed 24 hours a day, with maximum and minimum readings. The average temperature of the house without temperature control (T1) was 32 degrees vs 26.5 degrees for the treatment with fans and nebulizers (T2) and the average relative humidity was 60% and 73% respectively, while the average production was higher in the batch of animals with ventilation and nebulization (85.88% vs 79.44%). The consumption of bird feed / day was also affected since the T2 shed consumed 91 gr meanwhile the T1 shed was 87.11 gr on average during the test time, at the end of the test, average weight for T1 was 1440 gr and 1500 gr for T2. T2 Improves the quality of life of birds by reducing the temperature reflected in better animal performance that generates additional income Keywords: farm, temperature, posture, Productive cycle, food consumption
