SMART FeedingHow smart feeding can affect cow behaviour

What is the relation between cow behavior and availability of feed?
Availability
More frequent (smaller) meals, results in less variation in rumen pH and therefore a healthier rumen

Less sorting when cows are fed multiple times
With 10x feeding
24/7 the same

Dynamic feeding
When feed is 24/7 available where can we optimize?How wrong are we currently feeding our cows??
Economic optimization
• Economically most optimal milk yieldNOT maximal milk yield
Based on: Cost of concentrates Cost of roughage Profit of milk, fat and protein
• Individual optimization
Maximizing profit
Concentrate intake (kg/cow/day)
Milk price minus
feed cost (euro/day)
Maximizing profit
Individual efficiency (%)
Input constant
Input related to efficiencyIncrease of profit
Decrease of loss
Margin (euro)
The dynamic model is developed in cooperation with the Animal Sciences Group, Wageningen UR.
Change your way of thinking!
1. Fixed feeding: subjective based on farmers perception
2. Feeding by feed table: static calculation based on herd average
3. Dynamic feeding: individual calculation and optimisation (kg milk + % fat and protein)
Dare to Dairy individualy!
