What is the best way to feed dairy cows?
Feeding a total mixed ration (TMR) that contains all the feeds and nutrients the cow needs is an effective, efficient and profitable way to feed dairy cows. Managing TMR daily can make sure your cows receive enough nutrients for good health, milk production and reproduction.
Is total mixed ration a good idea for dairy cows?
The many benefits of total mixed ration are weighed against their disadvantages for farmers to decide whether such feeding system is for them to adopt. The use of total mixed ration (TMR) in dairy cows is so widespread these days that we often forget there are still enterprises that rely on older feeding systems.
Why manage TMR for dairy cows?
Managing TMR daily can make sure your cows receive enough nutrients for good health, milk production and reproduction. Proper nutrition leads to healthy and high-performing dairy cows. Cow rations must contain the following: These feed sources provide nutrients needed for milk production, growth and reproduction.
What should I feed Mid-lactation cows?
Mid-lactation cows should be pregnant with milk production averaging 75 to 85 percent of the high group. Feed this group a ration higher in forages and slightly less nutrient dense than the high group ration.
What is the best thing to feed dairy cows?
Dairy cattle should consume enough forage material – pasture grasses, fodder, and silage – to meet their daily caloric requirements. This can be achieved through grazing, using feeding equipment, or a combination of both. Common wet and dry forage materials include corn, barley, hay, alfalfa, and pasture grasses.
What can I feed my dairy cow to increase milk production?
Provide a flake of alfalfa/grass hay for the first five days after calving. Early lactation diet should contain plenty of good quality digestible fiber (31 to 35 percent neutral detergent fiber). Maintain fiber mat with consistent feed intake and avoid empty bunks.
What type of nutrition should we feed to dairy cattle to increase their milk yield?
The high producing dairy cow requires a diet that supplies the nutrient needs for high milk production. Carbohydrates, amino acids, fatty acids, minerals, vitamins, and water are all nutrients required by the lactating dairy cow to meet the demand by the mammary gland to produce milk and milk components.
Can dairy cows eat just grass?
4. 100% grass-fed dairy means exactly what it says: milk from cows that eat grass and only grass. No corn, no soy, and no other grains, ever. The cows may receive nutritional supplements if needed, like molasses and minerals, but it's a very small amount — similar to a human taking a daily vitamin.
What type of food should be given to milk producing animals?
Answer. dry forages for pasture (fresh forage) or high quality Alfafa hay, Alfalfa grass mixed with hay, grass hay or straw, silage etc.
Is sorghum good for dairy cows?
Sorghum grain can be an effective source of starch for dairy cattle. Starch is the primary energy source in dairy cow diets when feeding for high levels of milk production. Utilization of starch in the rumen is a primary concern for improving milk yield and efficiency of production.
How do you increase milk quality in cows?
Tips for Improving Milk Quality in Transition CowsMaintain good foot, leg and tail hygiene. ... Eliminate employee-caused problems. ... Practice proper milking procedure. ... Make sure your equipment is working properly. ... Incorporate dry-off management strategies.
What minerals do dairy cows need?
For the dairy cow, the major minerals (macrominerals) required are calcium, phosphorus, magnesium, potassium, sodium, chlorine, and sulfur. Minerals required in much smaller, trace amounts (microminerals) include iodine, iron, cobalt, copper, manganese, zinc, and selenium.
Do dairy cows Need grain?
Grain: Dairy cows do eat some grain, which usually makes up less than one-quarter of their diet. Some has been grown specifically for cows, and other types have been recycled after food or beverage production -- like barley that has been used first to brew beer.
Can cows survive on hay alone?
While some cows can sustain many of their needs on grass alone, they are usually the non-lactating cows (i.e., cows that aren't producing milk). A lactating dairy cow has a high metabolism, and is very similar to a marathon runner or high performance athlete.
What do you feed cows other than grass?
Everything! Commercial cows usually eat a TMR (total mixed ration) with grass and corn silage. Total mixed rations may contain byproducts like cottonseeds, corn gluten, almond hulls, and soybean meal. In addition to TMR feed – cows love to graze and snack on alfalfa, clover, and other grasses, shrubs, or legumes.
How can I increase milk production?

Gently massage breast before and during feedings.Use relaxation techniques to reduce stress and promote the flow of breast milk.Provide skin to skin time with your baby for about 20 minutes after feeds.More items...
What causes a cow not to produce milk?
Overcrowding at the feed bunk can decrease feed intake especially in fresh and early lactating cows resulting in lower milk production. Sometimes overcrowding with other contributing causes can result in lowered milk production even when it appears that no feeding and management practices have changed.
How to reduce dustiness in cows?
Additionally, adding 1 to 3 percent animal fat or oil can reduce dustiness. Spraying on 3 to 7 percent liquid molasses or blends, too, can reduce fines, lower dustiness and improve palatability. Robotic grain mixtures usually are pelleted to avoid dustiness and encourage cows to consume their allotment.
Why is topdress important for cows?
A palatable protein topdress can be important if protein is fed individually to cows based on their level of milk production and needs. This topdress protein supplement should contain rumen undegraded protein sources, including lysine and methinione.
How to test for rumen ammonia?
1. Conduct individual cow MUN (milk urea nitrogen) tests. MUN values reflect the degree of rumen ammonia capture. You should target 10 to 14 mg/dl with levels as low as 8 in fine-tuned cows. 2. Feed 1 to 2 pounds of forage dry matter 30 minutes to 1-1/2 hours before feeding 6 to 7 pounds of grain mixture.
What is meal complementation?
Meal complementation refers to a balance of rapidly degraded protein sources (such as pasture-based systems) with rapid carbohydrates such as sugar or ground cereal grain sources (such as 800 micron shelled corn or a liquid supplement). These rapidly degraded sources are balanced with slower protein and carbohydrate feed ingredients in the ration.
What is component feeding?
Component feeding is an art form. For success, balance your rapidly degradable nutrients with feeds that break down slowly. By Mike Hutjens, University of Illinois. The author is a professor of animal science emeritus at the University of Illinois, Champaign-Urbana. While TMRs may dominate feeding today, some herds still component feed their cattle.
Why is grain palatability important?
Grain palatability a must. Palatability becomes an important factor to ensure cows consume the grain mixture because it may be fed separately from forages. Cows reduce their feed intake when offered dusty grain mixtures with fine particles. High-moisture corn (over 25 percent moisture) is a palatable grain source.
Can topdressed protein be raised?
Topdressed protein levels may be raised at a faster rate than the grain energy fractions. 6. Ask your nutritionist to balance several rations at different levels of milk production and lactation number (heifers will have a growth requirement). These rations will provide topdressing and feeding guidelines.
How does a TMR mixer help cows?
TMR mixers can reduce the work of feeding cows and save labor costs. A TMR provides more control and accuracy over the amount of feed given than separate ingredients. Feeding a TMR that’s correctly balanced for your cows can increase milk production 1 to 2.5 kilograms per cow daily.
How many milk production groups should a TMR herd have?
In general, producers using TMR should have at least three milk production groups and a dry cow groups. Suggested groups for a TMR fed herd include the following.
What is a total mixed ration (TMR)?
A TMR is a method of feeding cows that combines feeds formulated to a specific nutrient content into a single feed mix. The mix contains the following feeds.
What percentage of milk should a mid lactation cow produce?
Mid-lactation cows should be pregnant with milk production averaging 75 to 85 percent of the high group. Feed this group a ration higher in forages and slightly less nutrient dense than the high group ration. Plus sign (+) if content is closed, 'X' if content is open.
What does a TMR do for cows?
It’s harder for cows to be picky while eating. A TMR lowers the risk of digestive upset, stabilizes rumen pH and optimizes rumen feed digestion.
What does TMR do for rumen?
A TMR lowers the risk of digestive upset, stabilizes rumen pH and optimizes rumen feed digestion.
Why balance a cow's feed?
You must balance the nutrients in a ration to avoid excesses or deficiencies. Balancing rations to meet your cows’ nutrient needs can optimize feed digestion and use.
How does TMR feed help cows?
Each mouthful of feed that the cow consumes contains the proper amount of ingredients for a balanced ration , resulting in a more stable and ideal environment for the rumen microbes and providing adequate carbohydrates and nitrogen sources that vary in their ability and rate of rumen breakdown. This in turn can lead to production of higher levels of microbial protein by the rumen microbes throughout the entire 24-hour day. A 4% increase in feed utilization can be expected when using a TMR compared to a conventional ration of forage and grain fed separately, twice daily. In addition, the ability to use feeds with various rates of breakdown is enhanced, often enabling even better nutrient utilization. Farmers can also utilize a greater variety of byproduct feeds with a TMR, thereby allowing for possible ration cost savings. The incidence of digestive and metabolic problems often decreases when a TMR is fed, and milk production has been shown to be as much as 5% higher with a TMR compared to conventional rations as a result of these benefits.
How to achieve maximum performance from cows?
First, monitor forage and feed inventory on a regular basis and allocate to the appropriate animal group. Second, test forages and feeds several times throughout the year or when any noticeable change occurs . Lastly, update ration formulations based on milk production, milk fat and milk protein percent, current body weight and body condition scores, moisture changes in forages or high moisture feed ingredients, and prices of current feeds. Checking forage moisture on a frequent basis is critical to implementing a successful TMR system.
Why do cows need a three group system?
Using a one-group TMR system usually results in higher feed costs because more expensive ingredients such as undegradable protein sources, fats, and certain feed additives are fed to cows in later stages of lactation.
What are the disadvantages of TMR?
Disadvantages of a TMR Feeding System. Mixing or blending devices needed for the ration require small to moderate expenditures for equipment and maintenance. Further, it is important to follow the manufacturer’s recommendations for mixing. Over mixing can cause serious problems due to grinding and pulverizing the feed.
Why use feed scales?
Using feed scales both on mixing equipment in a feed area allows the quantity of each ingredient fed to be closely controlled. When a TMR is mixed properly, a cow cannot consume significantly more or less of a forage or concentrate than planned in the ration formulation.
What is separate TMR?
These can be formulated for fresh cows, early lactation cows, and mid- and late-lactation animals, as well as for far off and close-up dry cows.
How long to chop forage for TMR?
This generally is no more than 4 to 5 minutes–just long enough to achieve a good mixture.
How does increasing or decreasing the amount of TMR affect cows?
One of the most common misperceptions when increasing or decreasing the amount of TMR offered is to change the amount of forage offered while holding constant the amount of grains and other concentrates fed per cow. This change results in a misbalanced ration that can decrease milk production or result in health problems in the cows. One way many farmers adjust the amount of each ingredient in the TMR is to feed their cows as if the group has been expanded by two to five cows or been reduced by two to five cows.
Why do nutritionists balance rations for dairy cows?
When nutritionists balance rations for dairy cattle, they assume that the cow will receive a certain amount of dry matter from a particular feed. As the feed becomes wetter, more of the feed needs to be included in the TMR in order to provide the same amount of dry matter to the cows and keep nutrients in their correct proportions. The reverse is also true: as feeds become drier, less of the forage or feed needs to be included. Nutritionists often include a table along with their balanced rations to help the farmer adjust the amount of forage or wet byproduct to be added to the TMR as the dry matter content of feeds changes.
Why do cows chew their cud?
Cows need to consume adequate amounts of long forages or fiber in their TMR so that they can regurgitate the feed, chew their cud, and secrete saliva, which helps buffer the rumen environment so that the bacteria can efficiently digest forages. Studies show that cows chewing their cud may secrete 5 to 6 pounds of saliva daily. When nutritionists balance rations for dairy cows, they try to provide adequate amounts of effective fiber, or "chew factor," so that enough longer particles are present in the rumen to stimulate cud chewing.
Why is it important to evaluate feed not consumed?
Feed not consumed should also be evaluated. This evaluation helps diagnose any problems of excessive sorting behavior in cows. This diagnosis becomes extremely important when greater than 7 pounds of hay per cow is fed daily through a TMR and large amounts of cobs are left in the feed bunk. Even when a balanced ration is mixed properly, sorting of larger forage particles can lead to problems due to imbalances and lack of effective fiber for cud chewing that can result.
When increasing or decreasing the amount of TMR fed, the amounts of each forage, grain, and each of the?
When increasing or decreasing the amount of TMR fed, the amounts of each forage, grain, and each of the other ingredients need to be increased in proportion to the originally formulated TMR. Do not simply feed cows more forage if they clean up feed from the previous feedings.
What is a TMR cow?
Feeding a total mixed ration (TMR) ideally results in rumen bacteria encountering the same mixture of ingredients and nutrients in the cow's rumen throughout the day, a consistency that helps improve fermentation. It may also result in better intake by the cow herself and improve her milk production, health, and reproductive performance.
How to manage feed bunk?
In order to manage the feed bunk effectively, a daily log should be kept that shows, for each feeding, how much feed was fed and how much feed was left in the feed bunk from the previous feeding. This log becomes extremely important when more than one person is feeding the cows, as when the normal feeder is absent unexpectedly. With a daily log, each feeder can quickly and accurately determine what other people have fed and can adjust the amount of feed accordingly. The nutritionist can also use this information to make sure that the ration is as economical as possible, cows are actually consuming the expected amount of dry matter or feed, and potential problems are noted before they affect performance and the dairy operation's profitability. Table 1 shows a sample worksheet that can be used to record feed intakes and refusals.
Why do cows consume more dry matter?
Increased dry matter intake. As digestive functionality and health are sustained at high levels, and in conjunction with continuous feed availability, cows consume more dry matter. Not only that, but they cannot pick out undesirable (unpalatable, dusty, etc.) ingredients, leading to much better efficiency of feed utilization and less residual feed. In addition, as the dry matter intake is easily monitored, nutrition can be easily adjusted to match genetic potential and actual performance, not to mention the ability to perform quick nutrition challenge on-farm trials.
Why do cows eat smaller meals?
Thus, they tend to consume smaller but more meals per day, spread out evenly during their day. This prevents slug feeding that overloads the rumen with nutrients and unbalances the process. In contrast, rumen processes are optimized, digestibility improves, pH stabilizes and digestive upsets are minimized. This is because with each meal, the rumen microflora receive a balanced mix of all nutrients required for fermentation towards a desirable outcome.
Does TMR increase milk production?
The TMR technology offers many advantages that lead to increased milk production. But, that’s not all of it. There are side benefits that can lead to decreased feed cost. However, this is a much more difficult exercise, and one that needs to be attempted after a farm is successful in implementing the TMR feeding system.

General Approach to Formulating TMR
- The key to formulating TMR is to optimize dry matter intake. Total dry matter intakes should be consistent with production and breed (see Table 1). Intakes may be depressed when ensiled materials undergo abnormal fermentation. Forage dry matter should consist of good- to excellent-quality forages, especially for high-producing animals. Palatability of forages, the presence of ce…
