Overview

From animal characterization to diet — in just a few clicks

Characterize animals by species, breed, stage, weight, and performance goals. Enter available feeds and the system balances on a dry-matter basis, considering NRC, NASEM, BR-Corte, or custom requirements — at the lowest possible cost.

  • Optimize total diets by simulating market variations
  • Beef and dairy cattle, sheep, goats, and equines
  • NRC, NASEM, BR-Corte, or custom models

Complete technical control and
valued professional delivery

Custom equations, nutrient relationships, mix optimization — tools that expand technician autonomy from intensive feedlots to pasture systems.

Nutritional Participation Charts

Visualize inclusion of each ingredient and its nutritional contribution, enabling technical analyses and more precise formulation adjustments.

Detailed Technical Reports

Generate reports with key diet indicators, ideal for recordkeeping, technical follow-up, and presentation to producers.

Mix Optimization

Build, optimize, and save concentrates, protein mixes, and cores to use them as standardized ingredients in final diets.

Economic decision

Zootechnical and economic intelligence for more confident decisionsZootechnical and economic intelligence to decide with greater confidence

Windiet goes beyond feed balancing by integrating nutrition, performance, and economic results. Based on formulation, diet, animal characteristics, and operational costs, the system simulates scenarios and projects indicators to support decisions better aligned with client objectives.

  • Calculate cost per kilogram of dry matter consumed and evaluate diet economic viability
  • Project carcass development and finishing to support defining the best slaughter point
  • Compare performance, sales, and cost scenarios to identify the best economic result per head
