MARKET REPORT FEED & ADDITIVE MAGAZINE January 2024 61 functions, ensuring optimal growth and reducing nitrogen emission. It has been reported that a deficiency of certain amino acids in animal diets can lead to reduced immune and metabolic responses, which can make animals more vulnerable to disease and in some severe cases can even result in death. Furthermore, most of the structures (e.g. muscle) and metabolic reactions (e.g. enzymes, hormones) in animal tissue are catalysed by proteins. Therefore, protein synthesis is essential for the maintenance of the life process. CLASSIFICATION OF AMINO ACIDS IN ANIMALS There are more than 300 different types of amino acids known to exist in nature. About 20 of these are important components of proteins in animals and are associated with muscles, connective tissues, skin, feathers, hair, horns, blood, enzymes and hormones. Amino acids essential for animals are generally classified into two main categories. The first of these is essential amino acids. Essential amino acids are a group of amino acids that the animal cannot synthesise on its own. In order for animals to fulfil their normal functions, these amino acids must be taken from outside through feeding. Essential amino acids include phenylalanine, histidine, isoleucine, leucine, lysine, methionine, threonine, tryptophan, arginine (included in the non-essential amino acid group in some sources) and valine. These amino acids are usually added to animal feed in pure form or as part of a mixture to meet the specific nutritional needs of different animal species. The second category of amino acids is non-essential amino acids. Non-essential amino acids are amino acids that can be synthesised in the animal's body. This group includes alanine, aspartic acid, cysteine, cystine, glutamic acid, tyrosine, glycine, proline, hydroxyproline and serine. FEED AMINO ACID MARKET AND FORECASTS According to a report by Market Research Future, the feed amino acids market size will grow at a compound annual growth rate (CAGR) of 7.3% between 2022 and 2030, reaching USD 49.5 billion. However, this data does not coincide with the data of many other research companies. For example, according to Verified Market Research's (VMR) May 2023 report, the global feed amino acids market, which was USD 5.34 billion in 2021, will grow at a CAGR of 5.9% from 2023 to 2030, reaching USD 8.88 billion by 2030. The report prepared by Future Market Insights (FMR) also provides forecasts closer to the VMR report. According to FMR's report on the feed amino acid market, the market size will be around USD 7.81 billion in 2023. The report forecasts that the market will grow at a CAGR of 5.5% and reach USD 13.34 billion by the end of 2033. FMR also estimates that the total market value of the global amino acid market will be USD 61.47 billion in 2026.
