Amino acids are the basic building blocks of proteins and indispensable components of animal feed. Depending on the animal species, physiological stage and performance, the requirement varies, with a particular focus on essential and first-limiting amino acids such as lysine, methionine, cysteine, threonine or tryptophan.
For optimal feeding, knowledge of the crude protein content alone is not sufficient, but requires detailed information on the amino acid composition. Since this can vary depending on the raw material, origin, harvest year or production batch, regular analysis of the feed is necessary.
The analysis results provide information on whether amino acids need to be supplemented in the product or during feeding, and give manufacturers security when drawing up product specifications and packaging information. This is because incorrect amounts of amino acids can lead to reduced performance, poor feed conversion and adverse effects on animal health and the environment.
In addition to lower yields and higher feed costs, nitrogen or ammonia excretion plays an increasingly important role in this context. The right amino acid composition can lower the crude protein requirement and thus reduce nitrogen excretion as an environmental aspect. Therefore, the analysis of the amino acid composition is an important key point for a demand-oriented, economical and ecological animal feeding.
Pets, especially dogs and cats, have specific dietary requirements depending on their life stage and health status. In species-appropriate nutrition, the amino acid profile plays an important role. Essential amino acids, which cannot be produced by the body itself, must be ingested in the right amounts through the feed.
An analytical amino acid profile provides pet food manufacturers with reliable information about which amino acids are contained in the feed and in what quantities. In this way, recipes can be optimized to meet requirements, and these analyses also serve to ensure quality. Correctly reported amino acid contents can also make it easier for pet owners to feed their pets.
Our accredited laboratories carry out the determination of amino acids according to the classical methods according to VO(EG) 152/2009 and VDLUFA.
In addition, we offer you the possibility of having the analysis carried out using our own modern procedure based on microwave technology and HPLC-MS/MS. This modern method is a reliable, fast and cost-efficient alternative that can also detect other substances such as taurine, hydroxyproline, hydroxylysine, gamma-aminobutyric acid (GABA) or ornithine. SGS thus offers you a comprehensive range of methods, and we will be happy to advise you on the selection of these methods.
In summary, these amino acids can be determined: alanine, arginine, asparagine, aspartic acid, cyst(e)in, gamma aminobutyric acid (GABA), glutamine, glutamic acid, glycine, histidine, hydroxylysine, hydroxyproline, isoleucine, leucine, lysine, methionine, ornithine, phenylalanine, proline, serine, taurine, threonine, tryptophan, tyrosine, valine.
