The Feed Ration Calculator helps build a balanced feed mix by entering Animal Type, Weight, and nutritional targets, then adding each ingredient's weight, dry matter, and protein content to get Total Crude Protein, TDN, and Feed Efficiency.

TDN measures the energy value of feed ingredients. It represents the percentage of feed that can be digested by the animal for energy. Higher TDN values indicate more energy-dense feeds, which are crucial for meeting livestock energy requirements.
Crude protein requirements vary by animal type, age, weight, and production stage. Growing animals need 14-18% CP, lactating dairy cows need 16-18%, while mature beef cattle may only need 8-12%. Consult with a nutritionist for specific recommendations.
If your ration is deficient in protein or energy, animals may experience reduced growth, poor reproduction, lower milk production, or health issues. You'll need to adjust feed ratios or add supplements to meet requirements.
Use laboratory-tested values when possible, especially for homegrown feeds. Book values can vary significantly from actual feed composition. Regular testing ensures accurate ration formulation and optimal animal performance.
Yes, most commercial rations use 3-8 different ingredients. This calculator focuses on two feeds for simplicity, but you can run multiple calculations to optimize complex mixes with grains, forages, proteins, and supplements.
Dry matter removes the water content to give true nutritional comparison. Fresh forages might be 25% DM while grains are 88% DM. Always calculate rations on a dry matter basis for accuracy.
Start with your cheapest feed that meets basic requirements, then add the minimum amount of expensive supplements needed. Consider local feed availability, storage costs, and seasonal price variations in your planning.
