ROSSI, Luiz A. et al. Analysis of reproductive performance and use of electrical energy in the acclimatized facilities of boars. Rev. bras. eng. agríc. ambient. [online]. 2012, vol.16, n.10, pp. 1121-1127. ISSN 1415-4366. http://dx.doi.org/10.1590/S1415-43662012001000013.
This study aimed to assess and compare two air conditioning systems in a setting where eighteen males of the commercial genetic line AG337, from AGROCERES - PIC, are housed. The animals in Group A were submitted to automated air conditioning through artificial ventilation and nebulization, while the animals in Group B were submitted only to manual triggering of the ventilation, according to the schedule practiced at the farm. The factors such as reproductive performance, animal thermal comfort, as well as climatic variables from the external environment of the housing and use of electrical energy by the environment controLλing system were considered. The results showed that animals in Group A remained in a comfortable environmental conditions though there was no improvement in the mean values of seminal volume and sperm concentration. It is worthwhile to mention that monthly increase in energy costs due to use of acclimatization and automation equipments were not significant as the equipments are of low energy consumption.
