EFG Software is a specialized software developer focused on poultry and pig nutrition decision-support tools. The company emphasizes an open-theory approach, sharing the underlying theory and parameter rationales behind its programs rather than presenting a black-box model. Through products such as WinFeed, a Windows-based feed formulation program, and Growth Models and Optimisation Routines, EFG Software provides integrated solutions that pass nutritional information to predictive models. By combining WinFeed with the Pig Growth Model and other simulation engines, EFG Software enables nutritionists, geneticists, and farm managers to design feeding programs tailored to specific genotypes and production goals with a view to economic outcomes. The software suite includes prediction capabilities for feed intake, growth, and carcass composition across broilers, turkeys, and pigs, and offers optimisation routines that aim to maximise margin over feed cost for different strains. Some software is available free of charge, reflecting the company’s commitment to accessibility and scientific discourse. EFG Software positions its tools as scientific aids for professionals in the feed industry, facilitating decision-making about genotype effects, feeding schedules, environmental conditions, and the economic implications of nutritional choices. The organization has developed multiple programs that articulate the interplay between diet formulation, growth performance, and economic results, providing users with informative insights into poultry and pig science and experimentation. The company’s contact footprint includes individuals such as Colin Fisher in Edinburgh, UK, and Rob Gous in Stellenbosch, South Africa, indicating a transcontinental presence and collaboration network within the nutrition science community. EFG Software’s content and structured data indicate a focus on research-driven software that supports practitioners in designing feeding strategies that optimize performance while considering environmental and operational constraints. The company’s philosophy rejects ‘black box’ approaches, preferring transparent methodologies that enable modification and customization to meet client-specific needs. As a software developer serving researchers and professionals, EFG Software continues to advance its modeling capabilities, aiming to expand the applicability of its growth models and simulation tools across different species and production contexts, while maintaining a strong commitment to scientific rigor and practical usefulness for the workplace.
