ATR Futtermittel für Milchvieh

ATR pure cattle feeds

Cattle feeds suitable for the production of foods labelled as “Non-GMO”.

Any raw materials originating from genetically modified plants are excluded from feeds in the ATR FREE product line. We replace genetically modified soy meal with raw feed materials like rapeseed meal, Optilak 33 (trademarked rapeseed meal), rapeseed expeller and sunflower meal, as well as urea to provide nitrogen for the rumen microbes. By choosing these components we can produce feed with comparable values for crude protein and uCP.

ATR dairy feed concentrates

ATR’s range of dairy feed concentrates encompasses price-optimised dairy feed mixes with 6.7 and 7.0 MJ NEL. Today, the varieties of energy level II are only of minor importance.

Assorted feed concentrates can additionally be enriched with grain maize. These maize varieties currently contain 20% grain maize, for example ATR 75 M (18% RP/6.7 MJ NEL with 20% grain maize) or ATR 720 M (20% RP/7.0 MJ NEL with 20% grain maize).

High milk yields can also be reached using these concentrated feeds. However, they cannot guarantee a consistent composition with highly consistent starch contents, for example. For this purpose you should implement our ATR professional feed line of products.

ATR expert feeds

The ATR expert product line focuses on optimising uCP. These concentrates for dairy feeding have higher uCP contents than our standard feed and the crude protein content is reduced by one percent. Further restrictions ensure a composition of greater stability. The product names indicate the uCP content as well as the energy level, i.e ATR 175-IV contains 175 g uCP and provides 7.0 MJ NEL of energy.

Usable protein is a critical factor in many rations for dairy cows. As such these feeds are economical solutions, resulting in improved milk yields.

Our ATR expert feeds can also be enriched with 20% grain maize in order to provide dairy cows with increased resistant starch.


Usable crude protein (uCP) is considered when calculating the rations for dairy cows, heifers, and bulls, and – aside from the energy content – it is a determining factor for milk yields, growth, and daily weight gains. Crude protein was used in Germany for such calculations even before the parameter “usable crude protein” was introduced. The common classification of concentrates for dairy feeding in 2%-increments of crude protein dates back to this time. For this reason crude protein is used as restriction (limitation) for optimising mixed feed, although the uCP is the more important parameter. As a result crude protein is sometimes forced into feed mixtures even though it is more efficient to optimise in terms of uCP, the value determining parameter.

This insight motivated us to produce a dairy feed product line that serves as an alternative to common standard feed. In this line we have optimised the concentrated feed based on the uCP values and reduced the crude protein content by 1% and/or do not force crude protein into the mixtures using conventional methods. Thereby the positive RNB value remains unchanged, as required.

Benefits of the ATR expert feeds

  • Reduced crude protein contents provide relief for the dairy cows’ livers
  • Minimum starch contents ensure fast availability of carbohydrates
  • Fixed minimum content of resistant starch
  • Mixtures of greater stability due to more ingredient restrictions
  • Fixed upper and lower limits of main components
  • First dairy feed concentrates incorporating the idea of “less nitrogen input from feeding”
  • uCP content evident in the product name

ATR expert feeds

  • More usable protein
  • More milk from feed concentrate

ATR professional feeds

The ATR professional feeds are characterised by stable mixtures with further restrictions. These dairy feed concentrates are also optimised in terms of the energy level and crude protein, as well as the uCP, starch, and resistant starch. By doing so, larger shifts between the components are eliminated. The restrictions concerning starch ensure a stable proportion of cereal grains.

All ATR professional brand varieties contain at least 12% Optilak 33 (trademarked rapeseed meal) and the maize varieties contain at least 20% grain maize.

The ration calculation programme developed by our ATR technical advisers is based on the rumen fermentation parameters as well as the glycogenic energy values of these feed varieties. A more detailed overview of the different ATR professional feed varieties can be found in our brochure “ATR Profifutter” (ATR professional feeds, in German), available from our ATR field staff members .

ATR top milk with GlucoPan®

Since March 2011, ATR Landhandel has been offering ATR top milk with GlucoPan®, a feed line for high yielding herds and all dairy farms striving for higher annual milk yields per cow.

The objectives of this line of dairy feed concentrates

  • Increased milk yield
  • Higher levels of milk ingredients
  • Improved feed conversion rate
  • Increased profit

ATR’s top milk feeds are characterised by high energy levels (minimum 7.2 MJ NEL) and very high starch contents. The concentrates are optimised in terms of various restrictions:

  • Starch
  • Resistant starch
  • uCP
  • DVE
  • Glycogenic energy
  • Rumen fermentation parameters

This leads to extremely stable mixtures with minor fluctuations regarding composition, which in turn have a consistent effect in the rumen. Besides the values from the German protein rating system, we also use Dutch requirements to calculate our concentrates for dairy feeding (DVE, OEB, Gluco TN, FRE 0-2, FRE >2, FK 0-2, FK >2). This enables us to obtain additional information, resulting in even more precise calculations of rations.

Main components

Maize, wheat, rye, barley, Optilak 33 (trademarked rapeseed meal), soy meal, rapeseed meal, rapeseed expeller and dried pulp.

Minor components

Sunflower expeller, palm expeller, soy hulls, vinasse, molasses, minerals, pre-mixtures of vitamins and trace elements.

ATR top milk feeds are used in the GlucoPan® concept, which means that rations are calculated in advance, using the most precise staple feed values possible. These should reflect the digestion rate of crude protein and carbohydrates in the staple feed (rumen fermentation parameters). Furthermore, all feed components implemented are priced, so that the costs per kg of milk can be determined. This enables a comparison of the rations in terms of costs versus estimated milk yields. Feeds with higher prices leading to improved milk yields may ultimately result in lower feeding costs per kg of milk.

Please see the GlucoPan® page for a detailed explanation of our GlucoPan® concept, or feel free to contact our expert cattle advice team to discuss the application possibilities, without any further obligation.

Before introducing our ATR top milk varieties, several practical trials were conducted, in which a top milk variety replaced feed concentrates in existing rations. The results showed that the top milk varieties, in combination with an improved ration calculation using the GlucoPan® concept, led to higher profitability based on improved milk yields, improved ingredients, and a reduced energy deficiency at the start of lactation.

Following you find an example of one of the trials. In the future, you will continue to find current references for the application of ATR top milk with Glucopan.

ATR protein and compensation feeds

Aside from approved VM varieties with crude protein contents of 25 to 35% and varying proportion of grain cereals, ATR offers compensation feed with a higher proportion of sunflower expeller and Optilak 33 (trademarked rapeseed meal), as well as urea as a source of nitrogen. This provides the ruminant a mixture of different protein carriers.

Although the simultaneous use of bypass protein together with urea was originally more or less unheard of, today we know that a synchronised application can definitely have its purpose. When bypass rapeseed meal is replaced by the uCP in soy meal, urea compensates for the loss of nitrogen/crude protein in the forestomachs.

When soy meal began trading at peak prices, many dairy farms replaced a great percentage of it with Optilak 33 (trademarked rapeseed meal). The lower energy content of Optilak 33 was generally not taken into account when feeding rations rich in maize silage, without suffering negative consequences.

Furthermore, ATR provides a range of pre-mixtures with a crude protein content between 24.0 and 42.5%, which evolved from existing component mixtures. The four-digit number in the product name stands for the crude protein content, i.e. VM 3800 P equals 38%.

The choice of variety used is based on the standard ration (proportion of grass/maize), the performance level of the herd, and the desired performance level of the standard ration. (How many kg of milk should the feeding ration yield?) The ATR technical adviser uses the milk yield from the last lactation group (>200 days of lactation) from the LKV feedback as orientation.

ATR mineral feeds – components

The ATR mineral feed product line offers our dairy farms a broad variety of mineral feed varieties designed to cover all farm feeding situations. Aside from mineral feed varieties –such as R 7760 AS Euter Fit, which sometimes requires the addition of feeding lime and salt to the diet ¬– we also offer the so-called “TMR mineral”: R 7690. The recommended ration for this mineral feed is 300 g per animal and day, with a composition as follows: 150 g R 7760 AS Euter Fit, 100 g feeding lime, and 50 g feeding salt.

R 7690 (available in German only)

ATR also provides R 7760 AS Euter Fit with further added ingredients to compensate for specific deficiencies:

  • R 7760 AS Euter Fit: + 150,000 mcg biotin = R 7762 AS Klauen Fit
  • Alternatively: + 1,000 mg beta carotene = R7763 AS Repro Fit

As a buffer mineral for preventing acidosis, we use R 7750 with sodium bicarbonate and magnesium oxide.

R 7750 (available in German only)

For feeding dry cows we provide the following mineral feed:

  • R 7566 with 4% calcium and 20% magnesium
  • R 7880 with 0% calcium and 20,000 IU Vitamin E (150 g results in 3,000 mg of vitamin E!)
