Feed is likely the single largest expense on a dairy, whether it is grown on farm or purchased from outside suppliers. Because of that, even small inefficiencies in storage, handling or mixing can quickly become expensive.
When feed accounts for close to half of a dairy’s total costs, managing it well becomes one of the biggest opportunities to improve profitability. Feed management goes well beyond ration formulation. How feed is stored, tracked, mixed and delivered can have just as much influence on the true cost of feeding the herd.
Shrink Starts Before the Bunk
Feed loss often happens unnoticed. Unlike milk production or reproduction metrics, shrink is not always measured directly. Yet it can occur at multiple points between harvest and the feed bunk.
Commodity sheds, silage piles, storage bags, loading areas and mixing processes all create opportunities for loss. Without a system to track or control it, small inefficiencies can build over time and eat into profitability.
Mike Brouk, Ph.D., professor and Extension specialist in the Department of Animal Sciences and Industry at Kansas State University, says minimizing shrink is one of the most overlooked economic opportunities on many dairies.
Designing Storage with Loss in Mind
When building or upgrading commodity storage, the design of the structure can have a long-term impact on feed retention and efficiency. Many sheds are poorly protected from wind and moisture or are not sized appropriately for the ingredients they hold.
Over time, exposure to weather can degrade feed quality and increase losses.
Producers planning new storage facilities should think carefully about several design factors. Sevel tips include:
• Match the number and size of bays to actual feed use patterns
• Locate sheds where they are protected from prevailing wind, rain and snow
• Grade the site so water drains away from the storage area
• Allow easy access for loaders and mixing equipment
Brouk notes that some facilities end up using less than half of their physical storage space effectively because of poor layout or design limitations.
Managing Feed Inside the Shed
Infrastructure is important, but daily management also plays a major role in how much feed is ultimately preserved.
One of the most important principles is maintaining proper inventory rotation. Without it, older feed can accumulate in the back of bays where it loses quality or becomes spoiled.
Good feed management starts with simple practices.
• Use an all in, all out approach whenever possible
• Push older feed to the front before unloading new deliveries
• Keep batches separated so their nutrient values remain accurate
• Avoid unintentionally blending old and new ingredients
“Otherwise, you’ll end up with a back end containing feed that is months or even years old, lower quality and potentially spoiled,” Brouk says.
When outdated feed works its way into the ration, it does more than create physical loss. It can also reduce ration consistency and make it harder for nutritionists to predict cow performance.
Weather and Wind Losses Add Up
Environmental exposure is another common source of feed shrink that is easy to overlook.
Wind can carry away fine particles from dry commodity ingredients during both storage and loading. Rain and snow can also lead to spoilage along the edges of piles or near open shed entrances.
Several simple adjustments can help limit those losses.
• Install roll down curtains or tarps on open shed sides during periods when the building is not in use
• Use stacked bales or barriers to block wind from entering the structure
• Position loading areas where they are shielded from direct wind exposure
• Consider partially enclosed loading systems where possible
Even when feeding activity stops overnight, leaving commodity sheds wide open can allow wind to remove a surprising amount of feed by morning.
Loading Matters More than Expected
Another area where feed loss can occur is during the loading process itself.
When ingredients are loaded into mixers outdoors or in windy conditions, fine particles can easily be blown away before they ever reach the ration. Brouk says the load out location and technique can have a noticeable impact on feed retention.
“Load out itself is a critical control point where feed is lost if it is conducted out in the open,” Brouk adds.
Daily operating practices can also influence how much feed is preserved.
• Train feeders to avoid taking oversized scoops with loader buckets
• Watch for spillage along bucket edges during loading
• Use windbreaks near commodity sheds when possible
• Clean up spilled feed quickly before it spoils
Some dairies use power broom attachments on skid loaders to recover spilled feed and keep traffic areas clean. While the recovered feed may not always return to the ration, it prevents unnecessary waste and keeps work areas safer.
Managing Feed as One system
Reducing shrink is only one part of a larger shift in how many dairies are approaching feed management. Increasingly, farms are looking at feeding as a connected system rather than a series of separate steps.
That process often begins with better inventory tracking. Simple tools that monitor feed supplies and link them to ration requirements can help producers understand how long feed inventories will last.
By connecting inventories to herd size and ration formulation, producers can identify potential shortages earlier. That information can guide purchasing decisions, help plan crop acres and reduce the risk of emergency feed purchases later in the year.
Accuracy and Consistency
Once feed is properly stored and protected, the next step is making sure it is delivered accurately.
Small inconsistencies during batching can create ration variation that adds up over time. While shrink is often discussed in terms of physical loss, variation in ingredient loading can have similar economic consequences.
Some dairies are turning to automated batching systems that control ingredient loading with greater precision. In some cases, these systems have reduced deviations to very small margins. Improving batching accuracy not only reduces waste but also helps ensure cows receive the ration the nutritionist intended.
Feeding Systems are Becoming More Continuous
Feed delivery strategies are also evolving. Instead of delivering one or two large loads each day, some farms are shifting toward more frequent feeding.
Automated feeding equipment can mix and deliver smaller loads throughout the day, keeping feed fresher and more evenly distributed along the bunk. More frequent feed delivery can reduce refusals and encourage more consistent eating patterns. In some situations it also allows producers to manage bunk space more efficiently while maintaining stable intakes.
Small Improvements Can Have a Big Impact
The tools used to improve feed management vary widely from farm to farm. Some start with simple inventory tracking, while others invest in new storage facilities or automated feeding systems. Regardless of the approach, the underlying principle is the same. Small inefficiencies in feed handling can compound quickly when feed represents such a large share of total farm expenses.
Improving feed management does not always require major capital investment. Often the first step is simply measuring more carefully, managing storage more intentionally and tightening daily feeding practices. Over time, those incremental improvements in storage design, shrink reduction and batching accuracy can add up to meaningful gains in both efficiency and profitability.
