MODALITIES TO REDUCE NITROGEN EMISSIONS IN SWINE FARMS: REVIEW

The gas emissions have increased in recent years, which has exacerbated the greenhouse effect. In the livestock sector the main sources of emissions are considered to be the production, processing and transport of animal feed, manure decomposition, processing and transport of animal products (post-slaughter transport, refrigeration and packaging of animal products). A significant emission reduction, including nitrogen, are within the reach of animal producers. Adopting current best practices and technologies for feeding, raising and maintaining animal health, manure management, and greater use of biogas and energy-saving technologies would help the livestock sector to grow. reduction of greenhouse gases. This review aims to highlight the possibilities that pig farmers have in order to adopt strategies to reduce nitrogen emissions from farms.
