|Title:||Environmental Suitability Of Housing For Gestation Sows|
De Moura D.J.
|Abstract:||As swine production has been developed in Brazil, most research has been carried out in traditional areas of knowledge such as genetics, nutrition and reproduction. To obtain high quality meat is the main goal of producers, and welfare issues are not much understood. Behavior studies are helpful in showing the animal response to certain exposures, such as air quality and adequate overall rearing environment. Welfare issues are gaining importance in Brazilian meat production as their destination is increasingly for supplying external market. The objective of this research was to evaluate the gestating sow rearing conditions, such as thermal and aerial environmental conditions, and noise level in two distinct types of rearing management conditions: in group room and in cages. The experiment took place in a commercial swine farm in the state of São Paulo. The following variables were recorded in the geometric center of the housing at 1.5 m above the floor: dry-bulb, wet-bulb and black globe temperatures; wind speed; noise level, and gas concentration. Data were statistically analyzed using ANO VA. Results showed that the air quality was good when compared to the standard thresholds in both rearing conditions. The chemical quality of the air inside the gestating rearing conditions can be considered good, since the average measures of the studied gases inside both housings didn 't exceed the critical values for gestating sows. Noise level data is within the norm. As to the temperature, for example, it could be observed that the obtained data is higher than what it required by the standard, therefore it may result in reproductive problems for the animals.|
