Evaluating environmental and economic trade-offs in cattle feed strategies using multiobjective optimization

Proposed solutions to anthropogenic climate change: A systematic literature review and a new way forward

“…The major challenge for animal agriculture, particularly the ruminant sector, is a reduction of methane and nitrous oxide emissions. Strategies proposed include ruminant vaccines, genetic selection, dietary manipulation and chemical additives [ 326 ], better breeding practices [ 327 ], improved fertility [ 328 ], improvements in pasture management/regenerative grazing [ 61 , 211 , 329 ], fertilizer and irrigation [ 324 ], optimized lifetime efficiency of dairy cattle and production [ 327 , 330 ], reduction in energy and water use [ 39 ], and manure management [ 328 , 331 , 332 ]. As with many other animal agriculture strategies, however, these approaches assume a ‘business- as -usual’ model and fail to address the inherently climate-damaging effects of an increasing demand for meat and dairy.…”

Recent advances in decision support for beef and dairy farming: modeling approaches and opportunities

“…Economic performance and biological yield are the most recurring performance measures. Also, several studies focus on environmental performance (Alqaisi et al., 2019; Breen et al., 2020; Marques et al., 2022; Zhao et al., 2022). In contrast to whole farm optimization studies, focus on animal welfare is more prevalent in the intrafarm optimization literature, with four articles making such considerations (Gülzari et al., 2018; Asamoah et al., 2020; Sekiya et al., 2020; Ferchiou et al., 2021).…”

“…In contrast, intrafarm models tend to have a narrower focus on decision making. Like the whole farm optimization literature, intrafarm optimization studies place a significant emphasis on feed decisions (e.g., Ferchiou et al., 2021; Marques et al., 2022; Zhao et al., 2022). Additionally, Table 10 indicates that intrafarm optimization studies commonly address decision making related to reproduction, culling, and biosecurity measures, along with the implementation and use of technology.…”
