Animal food

Given the importance that animal feed has in terms of the quality of animals for slaughter and the repercussions on human health, AENOR Laboratorio focuses its efforts on establishing a rigorous analytical control system that helps to guarantee the safety of foods used for animal feeding across the different stages; production, transportation, storage, formulation and consumption.

​AENORlaboratorio is authorised to carry out Salmonella self-control activities in poultry breeding farms in Spain.​​

Every animal species has a series of specific nutritional requirements; therefore, it is essential to carry out nutritional analyses in order to achieve suitable mixes.

AENORlaboratorio carries out, among other things

Determination of macronutrients

 
  • Fatty acids
  • Starch
  • ​Ash
  • Fibre
  • Fat
  • Protein
  • Carbohydrates and sugars
  • ​Humidity

Analysis of micronutrients

 
  • Amino acids
  • Minerals
  • Vitamins

Control of contaminants in raw materials: gossypol, free of mustard oil, KOH soluble protein, urea, theobromine.

The presence of these substances, some of them present naturally in vegetables, in animal feed can cause health problems in animals and alter the correct ingestion of these nutrients.

Mycotoxins are toxic products produced by some species of fungi and that proliferate in cereals, during both their growing and their storage and processing, if the suitable humidity and temperature conditions are given.​

There is a wide variety of mycotoxins that can affect people and animals.
AENORlaboratorio offers a broad catalogue of mycotoxins, using in each case the most sensitive analytical technique: ​​

Parameters

 
  • Aflatoxin B1, B2, G1 and G2
  • Aflatoxin M1
  • Deoxynivalenol (DON)
  • Diacetoxyscirpeno (DAS)
  • Fumonisins B1, B2
  • Neosonaliol
  • Patulin
  • Trichothecenes T-2, HT-2
  • Zearalenone

Technical

 
  • CL-FLD
  • CL-MS/MS
  • CL-DAD
Analysis of medicinal products in fodder, drinking water, channels, milk, animal organs, etc.


The use of medication, for both therapeutic and prophylactic purposes, is a common practice in animal production. These substances are usually administered through feeds and drinking water.

On the other hand, the use of unsuitable quantities of medications in animal feeds or the presence of residue in meat, milk or eggs, etc., can have harmful effects on human health, contributing to the development of microbial resistances.

The use of liquid chromatography equipment and mass detectors (LC-Ms/Ms) allows for trace-level residue of medicinal products to be detected and quantified, thus guaranteeing the correct dose, whilst also monitoring cross contamination and compliance with authorised maximum residue limits.

Main families of medications used in animal feeding:

  • Aminoglycosides
  • Benzimidazoles
  • Cefalosporinas
  • Coccidiostats
  • Diaminopirimidines
  • Phenicols
  • Lincosamines
  • Macrolides
  • Nitrofurans
  • Penicillins
  • Penicillins
  • Quinolones
  • Sulfonamides
  • Tetracyclines
  • Tranquillisers

​​Analysis of pesticides in cereals and compound feeds.

Most of the meat and meat products that we consume nowadays come from animals that are fed cereals and compound feeds from these cereals. Pesticide treatments applied in grain production can pose a risk to animal health. For this reason, the European Union has established maximum residue levels (MRL) for food and animal feed.

AENORlaboratorio is ENAC certified to analyse pesticides in cereals and compound feeds


  • Determination of heavy metals

Heavy metals can be toxic for human beings if consumed in certain amounts. Therefore, the exhaustive control of animal feed will contribute to reduce the presence of heavy metals in meat and fish.

 
  • Arsenic
  • Cadmium
  • Lead
 
  • Mercury
  • Nickel

In addition to the control of heavy metals, it is also important to assess other minerals such as aluminium, which is not really a heavy metal and finds its way into animals via zeolites and bentonites, and fluorine, a halogen, that finds its way into animals via phosphates rich in fluorine and which affects the absorption of nutrients. ​

Micrographic studies of fodder reveal their composition as well as identifying the presence of contaminants, such as toxic grains, parasites, insects, and so on

There is currently no specific legislation setting the criteria to be met by the water destined to animal consumption. In general terms, water for consumption by slaughter animals must comply with the following standard:

RD 140/2003, of 7 February, which establishes the health criteria for water for human consumption and which in Article 2 defines water for human consumption (previously referred to as potable/drinking water) as:

Any water used in the food industry for producing, treating, storing or marketing products or substances for human consumption, as well as any water used for cleaning surfaces, objects and materials that can come into contact with foodstuffs”.

Furthermore, water is frequently employed as a vehicle for administering medical drugs to animals. Drugs are chemical substances that can react with the medium, and certain characteristics of water can alter the stability of a medicine.

Taking into account these aspects, in general terms, the water employed in animal husbandry must be optimal in terms of microbiological and physical and chemical quality.​

  • Microbiological analysis: Aerobes, Enterobacteria, E. coli, Pseudomonas, Salmonella, etc.
  • Basic physical and chemical determinations: conductivity, ammonia, pH, nitrites, nitrates
  • Pollutants: heavy metals, pesticides, COV´s, HAP´s, microcystins, etc.
