Feed Efficiency

Afimilk’s solution for Feed Efficiency

The issue

Feed Costs Are Rising - and Variability Is Invisible

Feed is the single largest expense on a dairy, yet most producers are forced to manage it at the herd level instead of the individual cow level, largely due to limitations in available and affordable technology. That means: 

  • High-cost cows hide in the averages 
  • Inefficient eaters consume more than they produce 
  • Ration changes are made slowly because impact is hard to measure 
  • Culling and breeding decisions rely on production alone, not true profitability 
  • Nutrition programs are optimized on assumptions, not complete data 

Two cows eating the same ration can deliver very different returns. Until now, those differences were nearly impossible to see. 

How Afimilk Deliver Feed Efficiency Insights

The AfiCollar Feed Efficiency Service gives dairies what they’ve never had before: accurate dry matter intake per cow. Once paired with her milk production, both of which are updated daily, dairy producers can transform feed from a cost center into a measurable, optimizable performance driver while also finally: 

  • Identify each cow’s feed efficiency and income over feed costs  
  • Know exactly which animals are profitable and which aren’t 
  • Reduce feed waste 
  • Make economically smart culling and breeding decisions 
  • Build a more efficient herd over time 
  • Improve sustainability by selecting animals that produce more with less 

Key Benefits of Afimilk Technology

Profit Beyond Production

Measure each cow’s Income over Feed (IoF) to understand real profitability.

Smarter Culling

Remove low-efficiency, high-cost cows with confidence.

Genetic Progress

Select the most efficient animals to build a more economical, sustainable herd.

Daily, Actionable Insight

Make ration, grouping and management decisions based on current data, not monthly averages.

How the Feed Efficiency Technology Works

01

Measure Individual Dry Matter Intake

AfiCollar uses advanced algorithms to separate eating behavior from chewing, sorting, or rumination – giving a reliable measurement of dry matter intake for every individual cow, every day. 

02

Combine DMI with Production

Milk yield data is paired with intake to calculate: 

  • Feed Efficiency (FE) 
  • Income over Feed (IoF) 
  • Profit and loss per cow 

This creates a true economic snapshot of each animal. 

03

Turning Data into Decisions

AfiFarm analyzes and ranks cows based on efficiency, highlighting: 

  • The least efficient 10–20% for culling or breeding decisions 
  • High-efficiency cows ideal for replacements 
  • Group-level trends that indicate ration adjustments 
04

Driving Sustainability for the Short- and Long-Term

Cows capable of creating the same amount of milk with less feed require less crop inputs, which are gains that can be realized in the short-term. In addition, feed efficiency is a heritable trait. By selecting efficient cows year after year, producers can build a herd that: 

  • Produces more milk with less feed 
  • Has a smaller environmental footprint 
  • Reduces methane output 
  • Demonstrates stronger lifetime productivity 

REAL STORIES

“When you have their dry matter intake, you know for sure if that cow is above or below your threshold. It lets you fill every stall with the most efficient animal.”
