Health for humans, animals & plants

Feed Safety: Service, Analytics

Feed is used to nourish livestock and pets, is at the beginning of the food chain and thus has a major influence on food safety. In order to be able to guarantee this and provide optimum nutrition for our farm animals, the use of high-quality and, above all, safe and thus legally compliant feed is indispensable.

A maximum of feed quality and feed safety can only be guaranteed by a functioning, efficient interaction between the feed companies' own control systems and appropriate governmental supervision and control.

Our Institute for Animal Nutrition and Feed is available to the public, farmers, feed companies, the federal provinces, as well as the Federal Ministry of Agriculture, Regions and Tourism (BMLRT) and the Federal Ministry of Social Affairs, Health, Care and Consumer Protection (BMSGPK) for inquiries, statements, analyses and scientific advice.

Feed Service - Services

As a feed company, the legislator does not always make it easy for you to act in compliance with the law. This is because you have to comply with a plethora of regulations that are constantly changing. Every law and every change has practical implications. For example, with regard to the labeling of your feed, quality assurance or the export of feed. With our experts, you know you have partners at your side who will guide you safely through this maze of regulations.

We offer feed companies tailor-made solutions. With the following advantages, among others:

  • Expert opinions and test reports prepared by experts
  • Comprehensive and interdisciplinary advice from a single source
  • Simple and unbureaucratic processing
  • Pastus+ certification body

Expert opinion for feed

Evaluation of analytical results and preparation of expert opinions

As part of the preparation of expert opinions for feedstuffs, we check the analytical results submitted by you. In doing so, the analytical findings are checked in accordance with the legal requirements, such as tolerances or maximum values. We then issue an expert opinion on this. In the case of analyses carried out by us, the expert opinion can also be issued together with the test report.

Our offer

Do you need an expert opinion for existing analysis results of your feed samples in accordance with legal requirements (e.g. tolerances, maximum values) or would you like to have your samples analyzed and assessed by us?

Our experienced feed assessors check and evaluate the results of your analyses and, in addition to an interpretation, can also provide the assurance that your feed complies with the legal requirements with regard to the analyzed parameters. The following areas, among others, are covered by us within the scope of an expert opinion for feedstuffs:

  • Examination of analytical results with regard to legal requirements (such as tolerances, maximum values)
  • Examination and evaluation of feedstuffs with regard to legal requirements, composition, marketability according to the evaluated parameters and any potential hazards
  • Issue of an expert opinion

Labeling inspection of feed

Checking feed labels for legal conformity

As part of a labeling inspection, a label submitted by you is checked for conformity with the currently applicable legal regulations for the labeling of feed.

Our offer

Particularly in the area of labeling regulations, feed producers are faced with a multitude of requirements that must be met in order to properly label the feed. Our experienced and independent feed auditors check whether the labeling submitted by you complies with the legal requirements. In doing so, the labeling templates are checked both with regard to formal aspects and to the promotional messages, the so-called "claims".

Finally, you will receive a detailed description of the result and, in the case of "non-conformities", information on possible improvement measures. If your labeling meets the legal requirements, a corresponding confirmation can also be issued - if desired.

The following areas, among others, can be covered by us as part of a feed labeling inspection:

  • Formal inspection of the labeling (e.g. labels) of feedstuffs and claims
  • Detailed description of the result with indications for improvement measures
  • Issue of a confirmation (in case of conformity with legal requirements)

Certificates for feed

Issuance of Certificates for Feed and Feed Businesses

After checking the submitted documents, we issue certificates for your feed, which you need for the export of your products, such as Free Sales Certificates, Health Certificates or Certificates of Registration.

Our offer

While the trade of feed within the EU is very uncomplicated and uniformly regulated, the export to third countries is often more difficult. Here, each country has individual requirements that must be met in order to place a feed on the market in its territory. Proof of registration as a feed business in an EU country is usually the first step, followed by others, such as confirmation of EU marketability or freedom from certain undesirable substances.

We can assist you in this process with our know-how and the issuance of the required confirmations (according to the criteria you specify) as well as with the necessary analyses, if required.

The following areas, among others, can be covered by us:

  • Issuance of the Free Sales Certificate: marketability test based on a complete test of the formulation (valid for 6 months)
  • Issuance of the Certificate for product registration: for third countries/non-EU countries (valid for 6 months)
  • Issuance of the Certificate of Registration: confirmation of the existing registration of a company (valid for 6 months)
  • Issuance of the Health Certificate: based on the Feed Hygiene Regulation (EC Regulation No. 183/2005), confirmation of the absence of contaminants based on submitted regular self-checks or in a special batch (valid for 6 months)
  • Issue of Certificate of non-animal origin: confirmation of absence of animal components on the basis of submitted tests (valid for 6 months)
  • Issuance of Certificate of Analysis: information based on submitted certificates of analysis (valid for 6 months)

Sampling of feed according to Regulation (EC) No. 152/2009

Standardized sampling of feed

In the case of feed analyses carried out by us, it is possible to commission us to carry out standardized sampling. This is carried out in accordance with the requirements of EC Regulation No. 152/2009. Finally, you will receive a sampling protocol.

Our offer

In order to achieve the most accurate and representative results possible when analyzing your feed samples, standardized sampling in accordance with the requirements of Regulation (EC) No. 152/2009 is an elementary step.

For samples that you would like us to analyze, you have the option of arranging for us to perform sampling that meets these criteria. After the preparation for sampling (disinfection, labeling of the sampling bags), the sampling takes place (drawing of the individual samples, mixing and formation of the final sample, filling of the sample bags and sealing). Optionally, expert advice can be given with regard to analytical tests. Subsequently, you will receive a copy of the sampling protocol.

The following areas, among others, can be covered by us as part of the sampling of feedstuffs:

  • Comprehensive advice on the type of sampling
  • Sampling on site by specially trained experts
  • Preparation of a sampling protocol
  • Technical advice regarding the analytical examination

Carryover and mixer testing of mixing equipment for feedstuffs

Carryover control and/or verification of mixing accuracy.

Good mixing accuracy and uniform distribution of individual components is essential to produce a high quality feed. Likewise, carryover of additives to non-target species can have far-reaching consequences. Therefore, feed mixing equipment should be regularly checked for these two parameters to avoid deviations in the composition of the feed and, ultimately, a detrimental effect on animal performance.

Our offer

Within the scope of the mixing plant inspection, the mixing accuracy or the homogeneous distribution of the individual feed components is determined. In the course of the carry-over control, it is checked which quantities of a feed component can still be found in subsequently mixed feeds after a certain number of rinsing batches. For this purpose, a certain amount of Microtracer (colored iron particles) is added to the mixing equipment. The number of particles remaining in the product is then counted.

Our experienced and independent feed experts work with you to define the measurement batches, the mixing time, the entry points for the tracer and the sampling points. Samples are taken at different points in the mixing process. This is documented in a detailed sampling protocol. After evaluation of the samples using the rotation detector method and a statistical calculation, we prepare the test report.

The following areas, among others, can be covered by us within the scope of a carry-over and mixing test of feedstuffs:

  • Control of the carry-over of feed components after a certain number of rinsing batches.
  • Control of the homogeneity of mixing systems for feed production to ensure the consistent quality and mixing of the individual components
  • Evaluation of homogeneity or carry-over by means of rotation detector method and a statistical calculation
  • Issue of a sampling protocol and a test report

Training feed law

Feed law requirements in Austria and the EU

Feed law requirements determine the everyday life of a feed business. The abundance of regulations and their constant changes do not always make it easy for those concerned to act in accordance with the law. On the one hand, we are directly involved with our experts in the creation of legal texts (national and at EU level), and on the other hand, we have to implement them practically during feed inspections within the scope of responsibility of the Federal Office for Food Safety. We are happy to pass on the knowledge and experience gained from these activities to interested representatives of various target groups.

Our offer

Prepared training packages, on request also in the form of modules in compact form, for the following target groups:

  • Commercial entrepreneurs for livestock feeds
  • Commercial entrepreneurs for pet food
  • Farm animal owners (farmers)
  • Pet owners (especially dog and cat owners) and horse owners

Desired topics and focal points can be agreed upon in advance.

Contents of the training

  • Austrian feed law (feed law, feed regulation)
  • Essential aspects and contents of the EU feed law
  • Differentiation from other legal matters (especially food and medicinal products)
  • Target group specific case studies and practical applications (e.g. advertising claims)
  • Current topics (depending on relevance: salmonella, heavy metals, HCB, dioxin, etc.)
  • Questions submitted by the participants
  • Discussion

pastus+ certification program

The pastus+ certification program is a quality assurance system with the aim of establishing uniform quality criteria for feed above and beyond the legal requirements.

If required, our experts will provide you with comprehensive advice on the certification process, conduct the necessary audits, and evaluate and check compliance with the requirements at the farm. After successful evaluation, the audit protocol for AMA certification and the required pastus+ certificates are issued.

You can find more information about pastus+ here.

Soy quality determination

Soybean, -extraction meal and -cake are protein-rich feedstuffs that play an important role in feeding. Especially when using farm-grown soy, it is important to ensure that value-reducing traits are inactivated while optimally maintaining the quality of certain ingredients such as protein digestibility.

We have a broad spectrum of methods for determining quality-determining ingredients in soybeans. This includes antinutritive as well as safety- and quality-relevant parameters.

Antinutritive ingredients trypsin inhibitor activity * urease activity *
Quality-determining characteristics Protein solubility
Value-determining ingredients Crude protein Crude fat Amino acids (esp. methionine and lysine)
Safety-relevant characteristics Salmonella

*) In optimally treated feedstuffs, the trypsin inhibitor activity should not exceed 2 mg/g , the urease activity 0.4 mg/N/g/min.

Our staff is at your disposal for an informational discussion. Please contact us for this purpose.

Interlaboratory tests

Interlaboratory comparisons are an important means of quality control in chemical analysis. Laboratories accredited according to ISO 17025 are obliged to participate in such studies on a regular basis. Successful participation in interlaboratory comparison tests is a prerequisite for accreditation or for their continued validity.

An individual laboratory can use these tests to compare its own results from the testing of a particular sample with the results of other laboratories. In this way, the laboratory obtains information about the performance of its own methods. Our Institute for Animal Nutrition and Feedingstuffs organizes annual proficiency tests for feed-relevant parameters.

Interlaboratory test IAG - International Analytical Group, Section Feed Analysis

The IAG Interlaboratory test is an international proficiency test that is performed once a year. The ring test comprises the following samples, which are tested for ingredients, additives and undesirable substances:

The near infrared spectroscopy

Near infrared spectroscopy is a physical analysis method that can be used to analyze ingredients in various agricultural products within a few minutes. The principle of analysis is based on irradiating the analyte with electromagnetic radiation in the near infrared range (circa 680 - 2500 nm), which causes molecular bonds (-CH, -NH, -OH, -SH) to vibrate.

Depending on the type of bond, a spectrum can be used to infer the concentration of the unknown sample using statistical methods. For the quantification of the constituents, NIRS calibrations with data sets of known concentrations must be prepared in advance. Laboratory values analyzed by wet chemistry and collected in advance over several years serve as the basis for this.

The method is fast, inexpensive and easy to use. Furthermore, several parameters can be determined simultaneously with only one measurement. NIRS is therefore used continuously for quality control in many areas - from the field to the finished food or feed. The measurement is non-destructive and can be performed without time-consuming sample preparation (pre-drying or grinding). NIRS is particularly suitable for the determination of moisture, protein, fat, fiber and ash in cereals, flour, legumes, oilseeds and feed.

Applications of NIRS at the Institute of Animal Nutrition and Feeds

Our Institute for Animal Nutrition and Feed has many years of experience in NIRS analysis and uses self-developed calibrations for moisture, protein, crude ash or crude fiber depending on the crop.

The following analyses are currently offered:

Variety Water Crude protein Crude ash Crude fiber
Wheat x x x  
Barley x x x x
Rye x x    
Triticale x      
Durum wheat x x    
Oats x x    
Soy x x    
Corn x      

QS

QS is the world's largest inspection system for safe food, involving all companies involved in food production - from farmers to the store counter. Voluntary participation in QS ensures quality assurance that goes beyond official controls. Quality assurance in this system is based on self-checks, independent controls, monitoring programs and continuous internal control systems.

Feedstuffs play an important role here, as they contribute to keeping animals healthy and thus also have a significant influence on the quality of the food obtained from them. The feed sector is characterized by internationally branched commodity flows. The QS scheme relies on cooperation with other standard setters for a uniformly high level of feed safety. This facilitates the movement of goods, ensures the availability of goods and avoids unnecessary costs due to double audits.

In the course of QS feed monitoring, compliance with limit and guideline values is monitored, for example for mycotoxins, dioxins, plant treatment agents and heavy metals. We are the only laboratory in Austria that is recognized by QS for feed monitoring.

You can find more information about QS feed monitoring here.

Frequently asked questions about feed testing

All commercially available and self-produced feedstuffs, as well as all plants used for feeding animals, but also cereals and agricultural crops. Our range of services includes the following analytical tests: Ingredients, nutritional value, additives, minerals, trace elements, heavy metals, microbiological parameters (e.g. salmonella), microscopic examinations and technological properties (e.g. falling number) and other undesirable substances (mycotoxins, heavy metals, etc.). In addition, formal tests, such as the verification of labeling, are also carried out. For a detailed overview of our range of services, please refer to our examination catalog (see Downloads).

You can hand in your samples or send them by mail at the following locations:

  • AGES Vienna, Spargelfeldstraße 191, A-1220 Vienna, Tel.: 05 0555-0 (general sample acceptance for all tests, Mon-Thu 07.00-16.30h, Fri 07.00-15.00h).
  • AGES Linz, Wieningerstraße 8, A-4020 Linz, Tel.: 05 0555-41111 (for samples that are exclusively analyzed for elements and/or microbiological parameters, Mon-Thu 07.30-15.30h, Fri 07.30-15h)

When shipping samples, please be sure to include our order letter (see Downloads). Please make sure that the shipping container is tightly closed and as airtight as possible (if possible, do NOT use glass containers). For a representative homogeneous sample, the amount of sample material should not be less than 1/2kg - 1Kg (500g - 1000g). If the cold chain is not to be interrupted (e.g. in the case of moist samples), please state this DEPLICITLY on the packaging.

The duration depends on the respective question and the number of sample parameters to be analyzed. In general, however, it can be said that 95 % of our analyses are completed within 14 days. It should be noted that microbiological analyses (bacterial count, etc.) are carried out using cultural methods (cell growth on suitable nutrient media), which must be incubated for some time and therefore take at least one week.

In case of particularly urgent analyses (imminent danger), please contact our staff immediately.

The costs for your feed analysis depend on the desired parameters and the respective analysis effort and amount to between about 20 € and 450 € per analysis. For an exact cost information for the parameters of your choice, please contact the Institute for Animal Nutrition and Feed.

At present, it is not yet possible to retrieve examination results online. However, interim reports or preliminary information can be sent electronically (by email) upon request.

The "Weender Analysis" is the standard procedure for the determination of standard feed ingredients. The simple Weender analysis includes the determination of crude protein, crude fat, crude ash, crude fiber and moisture. The extended Weender analysis additionally includes the analysis of starch and sugar. The ingredients determined by the simple Weender analysis are among the mandatory labeling components of complete and complementary feeds (with the exception of mineral supplements) for food-producing animals, but also for cats, dogs and fur animals in accordance with Regulation (EC) 767/2009.

Undesirable substances are substances or products, other than pathogens, which are present in and/or on a product intended for animal feed and which may pose a potential risk to human or animal health or to the environment or which may adversely affect animal production. Undesirable substances in feed include, but are not limited to, heavy metals (such as arsenic, lead, cadmium, mercury), mycotoxins (such as deoxynivalenol or aflatoxins), plant-derived toxins (such as gossypol or theobromine), nitrite, hydrogen cyanide, organic chlorine compounds, and dioxins and dioxin-like compounds (PCBs).
