Treatments and utilization of swine waste in Brazil

Abstract

Swine wastes obtained from farming activities have the greatest impact on the environment by environmental agencies. Swine wastes together with poor management represent risks to the environment. In Brazil, these activities significantly increased in the last years and from 2014, the country became the fourth largest producer in the world. Swine wastes are generated in high amounts due to the confinement system used nowadays. This, coupled with the poor management of these wastes is now a serious problem to the environment. Therefore, the treatment of this waste is essential to maximize integration between environment and production. Based on this, the aim of this study is to perform a bibliographic survey of the swine waste treatment used mostly in Brazil and the ones that stand out most.

Behavioral Responses of Pigs Finished in Deep Bedding and Conventional Bed Systems

“…As the industry develops, there will need to be more attention focused on the environmental impacts of pig farming, since an increase in the concentration of animals will require compliance with soil and water conservation standards. Otherwise, the sector's growth may aggravate environmental problems, especially in regions where animal densities are already high and where greenhouse gas (GHG) emissions, as well as liquid and solid waste discharges per unit area, have already reached critical levels (Santos et al, 2014;Frigo et al, 2017).…”
