Special Issue Information

Dear Colleagues,

Livestock production systems are called upon for provision of the growing food demand expected over the next 30 years. Alongside the expansion of production, strategies to limit the environmental impact and ensure sustainable systems are necessary.

Some of the greatest challenges for intensive livestock systems relate to prioritized areas of interest such as the sustainable use of land resources and water, soil conservation and the reduction of emissions of atmospheric pollutants, including greenhouse gases. In this framework, applied research must find space for the study of novel approaches and techniques to be transferred to intensive farming systems in terms of designing efficient systems, processes and structures for the management of livestock and its productions, and promoting rational use of energy, water and plant resources.

The scope of this Special Issue is to gather theoretical and applied knowledge aiming to design sustainable systems based on innovative technologies, techniques and processes.

For this Special Issue, we invite original research papers and reviews improving knowledge and presenting scientific advances in techniques and practices applied to livestock production in intensive systems aiming to: (i) reduce the impacts on water, soils and air; and (ii) improve the efficiency of productions.

We are interested in topics including, but not limited, to:

  • Assessment and upgrade of environmental performances in intensive production;
  • Sustainable nutrient cycling in intensive livestock systems;
  • Techniques and technologies for reducing greenhouse gases and atmospheric pollutants emissions;
  • Optimization of manure management chain;
  • Designs and solutions for efficient energy and resource use;
  • Improvement of animal health, comfort and welfare in livestock management.

Brazil stands as one of the world’s leading producers of animal protein, ranking sixth in global egg production. However, estimated growth in production demand, along with environmental impacts, represents a potential threat to the sustainability of the food system. Methods for assessing and quantifying the environmental impacts generated by Brazilian egg production remain scarce, lacking current reports on comparative effects or guiding standards. The objective of this study was to conduct a life cycle assessment from cradle to farm gate, adhering to ISO 14040 and 14044 standards, for the battery cage egg production systems and associated products in Brazil, with the aim of supporting and promoting sustainability improvements in the Brazilian egg industry. The entire life cycle modeling and process sustainability analysis were executed using the openLCA software, integrated with the Ecoinvent database. Emissions related to egg production yielded results of 65.06 kg SO2 eq., 27.74 kg N eq., 3086.71 kg CO2 eq., 75,152.66 CTUe, 2.75 × 10−5 CFC-11 eq., and 10,044.68 kg MJ eq. per ton of eggs produced. These findings can serve as comparative benchmarks for future studies and for analyzing data across different egg production systems in Brazil. Full article

Pig farmers in Taiwan tend to overdose copper (Cu) and zinc (Zn) in animal feeds to ensure pig health. The application of Cu- or Zn-rich livestock compost to fields can result in high Cu/Zn residues in surface soil and violate limitations for zinc and copper in land applications. This study aims to extract Cu and Zn from sludge using organic acid or H2O2/organic acids. The livestock bio-sludge was dried and treated with different concentrations of acetic acid (1N, 2N, and 4N). The acid-extracted sludge was then treated with or without adding H2O2 during different periods (4, 24, and 48 h) to investigate the efficiency of acid extraction of Cu and Zn. The supernatant of the acid-extracted product was separated from the residues through centrifugation. Experimental results showed that the treatment set of dried bio-sludge with 2% H2O2 significantly promoted the removal efficiency of Cu and Zn from the bio-sludge (p < 0.01). The best removal efficiency of Cu and Zn from the bio-sludge was 40% and 70%, respectively, using 4N acetic acid in the 48 h group. The study shows a green method for extracting Cu and Zn from livestock sludge, enhancing the sustainability of intensive livestock farming. Full article
