About
CattleNutri helps nutritionists and producers build dairy and beef diets using published NASEM science:
• Dairy — NASEM Dairy Cattle, 8th Revised Edition (2021)
• Beef — NASEM Beef Cattle, 8th Revised Edition (2016), empirical (ELS)
Build diets ingredient-by-ingredient, load verified demo scenarios, review nutritional balances with citations, run a least-cost optimizer, manage a feed library, paste lab report text into custom feeds, and optionally sign in to sync saved rations.
Works offline. Interpretive scores are CattleNutri heuristics and are labeled in the app — balances come from the NASEM engines.
