Modern values ​​- with lots of power for feeding in practice

The analysis and evaluation of the results is detailed and comprehensive. Rock River Laboratory Europe provides many new and innovative values ​​for practice. This gives farmers and consultants a good tool for ration optimization and performance prediction. Some of them are described as follows:

The feed analysis report

NDF is an essential but at the same time limiting nutrient for the cow. It promotes animal health on the one hand, but limits its potential performance by lower energy concentration / kg compared to other main nutrients.

For the NDF to be as limiting as possible, its proportion in the basic feed should be as low as possible and the digestibility of the NDF should be as high as possible. In order to determine the essential part of the fiber, the supply of the cow with sufficient uNDF240 is to be ensured. The amount depends both on the lactation stage of the cow and on its weight. The uNDF240 value is that part of the fiber, which is not yet digested after 240 hours. The proportion of the fiber is represented by the aNDFom value and the digestibility by NDFD (in 24h, 30h, 48h, 120h, 240h).

For the calculation of the optimal supply of the cow with as much uNDF240 as necessary but as little as possible, the values ​​are fed into a ration calculation program based on the CNCPS model and deliver the calculated ration. In order for the feeding consultant and the farmer to be able to estimate the potential of the basic feed in advance, the TTNDFD and the dynamics NDF value are shown.

In addition, the digestibility curve of the crude fiber is compared with the other silages tested. The analysis results can be provided in different languages ​​and also include the digestibility curves.

Practical relevance

1. Dynamic analysis to understand the fiber digestion: A good tool to maximize health of  rumen health and the performance of the cows with homegrown feeds. The possibility of predicting and maximizing the protein synthesis of the rumen.

2. Analysis to determine carbohydrate digestibility in the rumen  (degradable fiber, starch, sugar, pectins, etc.) and thus predict the production of volatile fatty acids and proteins from the cow.

3. Analysis of the nitrogen fractions of the feed to describe the supply of nitrogen to the rumen microorganisms in conjunction with the carbohydrate fractions. Requirement to maximize the protein synthesis of the cow and to ensure the small intestine supply of the cow. The more precisely the potential of homegrown feeds can be determined, the more likely to avoid costly and harmful supply for animals. Avoiding over-supply not only saves costs in feedstuffs, but also saves the environment through reduced ammonia or phosphate loads.

For many years, American universities have been the world leaders in the research of fiber and starch digestion and their influence on the performance of ruminants. The dynamic assessment systems developed for this purpose, such as the CNCPS (Cornell Net Carbohydrate and Protein System), also help to clarify the processes of rumen digestion in their dynamics. CNCPS has been continuously developed since the beginning of the 1990s. Originally intended for research into ruminant nutrition, it has developed into a strong program for the exact prediction of the needs and also the formulation of rations. Numerous research work over the past 25 years, as well as the description of the rumen function and the metabolism form the basis of today’s CNCPS. The application in practice is realized by means of the two ration calculation programs AMTS and NDS approved for this purpose.

In these programs, a specific database of feedstuffs, some of which is regionally specified, helps to tailor the needs of the animals to energy, protein and amino acids.

The basis is always the adjustment with living cows or in vivo values. For example, the calculation of the demand for lysine and methionine, the ruminal N-supply and the milk-quantity prognosis is based on 389 experiments on 15 farms with 50 different rations (J.Dairy Sci. 98: 6361 ff). The postruminal N supply and possible milk output are made possible by BLUP model calculation. CNCPS allows the calculation of the first limiting nutrient in the ration.

The “Dynamic CNCPS” analysis package from Rock River Laboratory Europe provides all the parameters that the current CNCPS v 6.55 needs to calculate the rations for the herd. It has the 30, 120 and 240 h digestibility of the NDF for ground feed. It also provides TTNDFD (Total Tract Neutral Detergent Fiber Digestibility) exclusively. A number with unlimited  possibilities in practice.

Welchen Wert Futter tatsächlich hat

What value feed actually has “know” the up to 200 different Microorganism species in the rumen of the cow accurate. They represent the by far most accurate feed analysis and provide information for further formulation of the CNCPS model.

Visual report

Visual report for nutrient analysis

Reading analyzes requires some experience and training. Therefore the visual tachometers with the colors red, yellow and green, like at a traffic light, help to quickly identify where potential weaknesses and reserves can be, or whether the target has been reached. 6 Parameters are indicated with recommendations and arrange the analysis result provided.

KPS = Kernel Processing Score

KPS = Kernel Processing Score

The tool to check the chopping quality.

The Kernel Processing Score was developed to standardize how well the corn kernels were crushed in the chopping process.

It defines the particle size of the starch granules and allows a prediction of the digestibility of starch in the rumen and the digestive tract.

For this purpose, the silage to be tested is shaken through a sieve set over a period of 10 minutes with 278 oscillating movements / minute and 150 beats per minute. The individual components of the sieves are tested for starch content and NDF, ie fiber content, and provide very precise information on what the cow or microbes in the rumen have available. Also it indicates where it is available, in the rumen or intestine, and how quickly or slowly it is available to the cow. An important evaluation tool of corn in dairy nutrition.

Feinere Stärke bringt mehr Milch. Wenn sich der KPS von adäquat auf exzellent verändert, steigt die Stärkeverdaulichkeit um 6%. Das kann bis zu einem Liter mehr Milchleistung pro Kuh und Tag bedeuten.

Fine starch brings more milk. If the KPS changes from adequately to excellent, the starch digestibility increases by 6%. This can mean up to one liter more milk per cow and day.
