ACOUSTIC ENVIRONMENT AND GAS PRODUCTION IN DIFFERENT GROWING-FINISHING SWINE FACILITIES REA
Andrade,Rafaella R.; Campos,Alessandro T.; Cecchin,Daiane; Sousa,Francine A.; Amaral,Pedro I. S..
ABSTRACT This study aimed to evaluate gas levels and the acoustic environment (noise) of growing-finishing swine in different facilities, one composed of shallow pool (SP) and another of partially slatted floor (PSF). Sensors and a sound level meter were used to measure gas concentrations (CO2 and NH3) and noise at 1.50 meters above the ground and at animal height. Data on gas concentrations and noise levels were measured at 9am, 12pm, and 3 pm. Results showed differences (P<0.05) between noise levels at animal height and gas concentrations measured in relation to stall type and data collection time. The highest noise values were found in the shallow pool stall, measured at animal level. The highest NH3 (13 ppm) and CO2 (1174.5 ppm) values were observed...

Air quality in swine growing and finishing facilities with different building typologies AGRIAMBI
Cecchin,Daiane; Campos,Alessandro T.; Cruz,Vasco F. da; Sousa,Francine A.; Amaral,Pedro I. S.; Yanagi Junior,Tadayuki.
ABSTRACT The objective of this study was to evaluate the concentration of gases in three swine growing and finishing facilities with different building typologies, regarding floor and dividers. The experiment compared three treatments: pen with water depth, pen with partially slotted floor on the sides, and pen with partially slotted floor on sides and in the center. Measurements of instantaneous concentrations of ammonia (NH3 ppm) and carbon dioxide (CO2 ppm) were taken at animal level. The levels of sound pressure (dB) at animal level and at 1.50 m from the floor were also recorded. It was observed that the pen with water depth was the one with the highest average concentration of NH3. Although there was a significant difference in CO2 concentrations,...
