As leading scientists on the agricultural use of animals, we are needed to interpret the issues and propose mechanisms to effect the changes necessary to provide for futuristic relevance of agricultural animal use on the planet. We cannot simply justify the status quo to which we are undeniably linked. Critical thinking is required to address the urgent need to improve the sustainability of animal agriculture within the context of over-consumption of animal products in emerging and developed economies, health and welfare concerns at all levels of the agroecosystem, as well as increasing environmental impact. The rapidly changing context of sustainable development now includes adaptation to a changing environment and increasing vulnerability of production systems that are dependent on purchased inputs and because of which spread the impacts of animal production beyond the farm gate. Concurrently, changing size demographics of animal production units is switching responsibility for the impacts from farmer to corporate. Justification for the agricultural use of animals in the future will require out-of-the-box, system-level thinking to identify the win/win opportunities to improve sustainability as well as the metrics needed to direct true progress towards greater sustainability in the broadest sense of the meaning.

Abstract: The aim of this research was to determine the effect of housing system according to organic EU Regulation. for pig production, on performance, meat lipid content, fatty acids profile and indices of oxidative stability, histidinic antioxidants, coenzyme Q10, and TBARs. One hundred commercial hybrid piglets were allocated to each of three housing treatments: intensive (I); Free Range (FR), or Organic (O), Total lipid amount in meat increased in the order: O < FR < I. FR and O increased: dressing out, C20:1n9, Δ9-desaturase (C18) and Thioesterase indices in meat. Lipid, dipeptides and CoQ10 appeared correlated to glycolytic and oxidative metabolic pathways. We can conclude that all studied parameters were influenced by housing system, and that differences were particularly evident (P < 0.0001) in the O system, which produced leaner meat with higher oxidative stability. Hence, one of the aims of an organic production system (Council Regulation, 1999) is to enhance the rearing and diffusion of local genotypes, in addition, this rearing technique ensures high ecosystem sustainability, improving the role of agriculture in environment preservation.

Abstract: The environmental sustainability of intensified food production has been frequently questioned. The objective of this study was to assess sustainability of dairying in eastern Canada as impacted by forage proportion in cow diets, use of management-intensive grazing (MIG) versus year-round confinement feeding, and fertilizer N input intensity. To address this, the Dairy Sustainability Model was developed. A dynamic core model represents farm C and N flows, parameterized to reflect eastern Canadian data. Linked empirical models track energy use, GHG emissions, soil erosion, and cash flows, encompassing most upstream impacts associated with input production and usage, and downstream impacts to the farm gate following a life-cycle approach. Sustainability was described by a suite of indicators: nitrogen use efficiency (commercial N kg-1 of output N), nitrate leaching (kg N ha-1 y-1), soil carbon changes (kg ha-1 y-1), soil erosion rates (Mg ha-1 y-1), energy use intensity (MJ kg-1 of milk), greenhouse gas (GHG) emission intensity (CO2 equivalents kg-1 of milk), and profitability (net margin kg-1 of milk). The model predicts that increasing the proportion of forage in the diet, although being associated with lower milk production per cow and increased land area requirement per unit milk produced, will lead to improvements in most indicators including GHG emission intensity, due to upward soil carbon trends, and reduced nitrate leaching, soil erosion, fossil fuel inputs and field N2O emissions associated with increased use of forage crops. Simulations predict that employing MIG will improve overall sustainability relative to year-round confinement feeding, including marginally reduced GHG emissions and improved profitability, due to comparatively high forage quality, low costs, and low fossil energy use during the grazing season. Taken together, the results suggest that forage based feeding employing MIG in the grazing season can generate broad sustainability benefits relative to year-round confinement systems feeding more grain.
