The landscape of livestock farming has undergone a dramatic transformation in recent decades, evolving from small-scale operations serving local needs to today's intensive, industrial-scale production systems. This shift, while increasing productivity, has introduced a complex set of challenges for modern livestock producers. These challenges include uncertainties in international trade regulations, diminishing government support, heightened societal expectations regarding animal welfare and environmental standards, escalating production and feed costs, and growing food-feed competition for plant protein sources (Pomar & Remus, 2023).
In response to these mounting pressures, precision nutrition has emerged as a strategic solution offering multiple advantages. First and foremost is its contribution to efficiency—with feed representing the most significant expense in livestock production, precision nutrition minimizes overfeeding and nutrient wastage, resulting in improved feed conversion ratios and subsequently lower production costs.
The minimization of feed waste also has significant environmental benefits, as overfeeding often leads to excess nutrient excretion, contributing to environmental problems such as nitrogen leaching and phosphorus runoff.
Research demonstrates impressive results: for growing pigs for example, individually tailored daily diets can help farmers produce the same amount of meat while reducing lysine provisions by 25%, feeding costs by 8%, and nitrogen and phosphorus excretion by nearly 40% (Andretta et al., 2016). Furthermore, greenhouse gas emissions can be reduced between 6% and more than 24% (Ferguson et al., 2022). This is particularly significant considering that feed accounts for 70% of the environmental impact in pig and poultry production (Andretta et al., 2021).
