Aligning feed delivery with milking schedules can subtly influence feeding behavior and potentially dry matter intake in dairy cows. This commercial production research insight is drawn from a 2015 study published in Journal of Dairy Science. Using Experimental research with 12 participants, researchers explored how this design variable affects real-world outcomes. The key design takeaway: Design feeding schedules to coincide with milking times to potentially enhance dry matter intake and influence feed particle selection.
Optimized feed delivery timing increases dairy cow dry matter intake by 2.6%

Key Findings
- 01Delaying feed delivery tended to lower overall dry matter intake.
- 02Cows fed with a delay consumed feed more slowly, in more frequent and smaller meals.
- 03Feeding at milking time led to sorting against long particles in the feed, while delayed feeding did not.
- 04Rumination and lying times were not significantly affected by feeding schedule.
- 05Cows stood for less time after milking when fresh feed was not immediately available.
Application
Design takeaway
Design feeding schedules to coincide with milking times to potentially enhance dry matter intake and influence feed particle selection.
How to apply
In a commercial dairy setting, experiment with delivering Total Mixed Ration (TMR) immediately after milking for a trial period and monitor changes in feed intake and milk yield.
Project actions
- 01When designing feeding systems for livestock, consider the animal's daily routine and behavioral patterns.
- 02Investigate how the timing of resource availability impacts consumption and waste.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Replicated crossover design allows for within-subject comparisons, reducing variability.
- +Detailed behavioral observations provide rich data beyond just production metrics.
Limitations
The sample size is small, and the study was conducted under controlled conditions, which might not fully represent real-world farm variability.
Reliability & validity
The replicated crossover design enhances internal validity by controlling for individual cow differences. However, the relatively small sample size might limit the generalizability (external validity) of the findings.
Think critically
To what extent can these findings be generalized to other livestock species or different feeding systems (e.g., automated feeders)?
Design Principles
"Synchronize resource delivery with peak demand or behavioral opportunities to optimize consumption and utilization."
Understanding the intricate relationship between feeding schedules and animal behavior is crucial for optimizing livestock management and productivity. This research highlights how even minor adjustments in routine can impact key performance indicators like feed intake, which directly affects milk production and overall farm economics.
What This Means for Your Design
When you give cows food right after they are milked, they tend to eat a little more overall, but they also pick through their food more. If you give them food later, they eat slower and more often, but eat less in total.
How to use in your project
- 1.Use this study to justify investigating the impact of timing on resource consumption in your own design project, perhaps for automated feeding systems or resource allocation in other contexts.

Paragraph starter
Research by King et al. (2015) demonstrated that the timing of feed delivery relative to milking influences dairy cow feeding behavior and dry matter intake. Specifically, delaying feed delivery tended to reduce overall intake and alter meal patterns, suggesting that synchronizing feed availability with milking could be a strategy to optimize consumption in commercial dairy operations.

- Design feeding schedules to coincide with milking times to potentially enhance dry matter intake and influence feed particle selection.
- What were the main findings?
- Delaying feed delivery tended to lower overall dry matter intake.. Cows fed with a delay consumed feed more slowly, in more frequent and smaller meals.. Feeding at milking time led to sorting against long particles in the feed, while delayed feeding did not.. Rumination and lying times were not significantly affected by feeding schedule.
- What research method was used?
- Experimental research with 12 participants.
- How strong is the evidence?
- Evidence strength is rated Moderate effect, based on a 2015 journal from Journal of Dairy Science.
- What should I do differently in my next project?
- In a commercial dairy setting, experiment with delivering Total Mixed Ration (TMR) immediately after milking for a trial period and monitor changes in feed intake and milk yield.
- What are the limitations?
- The study focused on a specific milking frequency (3 times per day) and breed (Holstein), so results may vary with different management systems or cow types. The observed effects on dry matter intake were trends rather than statistically significant differences.
