To optimize the nutritional intake of cows, ensuring that they receive the appropriate balance of nutrients to maintain health, maximize productivity (such as milk yield or weight gain), and minimize waste.
Overview
Adjusting dietary practices to optimize nutritional content and feeding strategies has the potential to reduce GHG emissions per unit of milk produced.

Financial Considerations
Cost Savings: Adjusting dietary rations to reduce enteric emissions can lead to cost savings by optimizing feed efficiency and intake, reducing feed waste, and improving cow health which can consequently increase milk production.

Short
Dependency / Prerequisite
Prerequisites:
- Baseline measurement of current enteric emissions to track improvement.
- Availability of cost-effective feed ingredients.
Collaboration with a dairy nutritionist to develop and monitor the adjusted ration.
