5 indicators that your feed ration is suboptimal
Why is the optimal feed ration so important?
A well-balanced feed ration is the basis for the health, efficiency and profitability of dairy cow breeding. Even small errors in nutrition can lead to a decrease in milk production, fertility problems, or metabolic disorders. According to research published in the Journal of Dairy Science and MDPI, most problems in herds result not from diseases, but from incorrect balance of energy, protein and fiber.
Below we present the 5 most common indicators that may signal that the feed ration on your farm requires correction.
Decrease in milk yield and deterioration of milk quality
One of the first symptoms of suboptimal nutrition is a decrease in the amount of milk or a change in its composition - especially fat and protein content. As research has shown, an incorrect proportion of energy and protein in the diet leads to fermentation disorders in the rumen, which results in lower milk production and poorer utilization of nutrients.
Too little energy means lower milk production, too much - excessive fatness of cows and fertility problems. In turn, excess protein can lead to an increase in urea levels in milk, which is a signal that cows are not using protein effectively.
Changes in the behavior and rumination of cows
Cows themselves show when something is wrong with their diet - the so-called "cow signs", i.e. animal behavior, are one of the most reliable indicators of the quality of the feed ration.
If you notice that:
- cows chew less,
- lie longer after feeding,
- they choose only certain ingredients from the TMR more often,
it is a sign that the structure of the feed is incorrect or the proportions of fiber and energy are disturbed. Long pauses in chewing or fewer jaw movements per hour may signal too "fine" TMR or risk of ruminal acidosis.

Too much difference in body condition between cows or rapid weight loss after calving is a clear sign of problems with energy balance. When a cow does not get enough energy, it begins to use fat reserves, leading to a negative energy balance (NEB).
Research shows that high levels of NEFA and BHBA in the blood are reliable indicators of suboptimal nutrition - especially in cows in transition. In practice, this means that the problem with energy balance appeared much earlier than the breeder noticed it.
Rumen disorders and digestive problems
Incorrect composition of the dose - too little fiber or excess easily fermentable carbohydrates - leads to rumen acidosis. It results in loose excrement, decreased rumination and general weakness of animals.
In turn, excess fiber with low energy value may result in decreased feed intake and reduced milk yield. In the 2023 WUR report, it is noted that controlling the physical structure of the feed and regularly mixing TMR are the simplest ways to prevent such problems.
Instability in production results
If your herd has frequent fluctuations in milk yield, even though the dose has theoretically not changed, the reason may be inconsistency in feeding or mixing errors. Too large differences between the planned and actual dose mean that each cow receives something different, which disturbs the energy and protein balance.
MDPI studies emphasize that even a 5-10% deviation from the planned amount of TMR ingredients can have a noticeable impact on milk yield and herd health. That is why daily control and documentation of the feeding process is so important.
How does Smart Feed help catch these problems earlier?
Recognition that a feed ration is suboptimal is often only made when losses are already visible. That's why more and more farms use modern tools that enable constant monitoring of nutrition.
The Smart Feed application allows you to precisely control the feed supply process - from TMR planning, through connection with the feed wagon and the Dinamica Generale system, to the analysis of production data. Thanks to this, the breeder can immediately see whether the amount and composition of the feed correspond to the assumptions. Smart Feed also helps analyze the results - if milk yield decreases and feed intake increases, the system may suggest that the dose is suboptimal. This is a real saving of time, feed and money, and above all, a way to maintain a stable and healthy herd.
Suboptimal feed ration does not always give immediate obvious symptoms. Sometimes it starts with a slight decrease in rumination, other times with deterioration of milk quality or fluctuations in cow condition. Early recognition of these signals and correction of feeding is the key to maintaining an efficient and healthy herd.
Thanks to the Smart Feed application, every breeder can have full control over the feeding process - from planning to effects. Because in nutrition, as in every field of agriculture, precision is the basis of success. If you want to learn more - follow us on Facebook and check out the other articles on our blog!
