The assessment of amino acid requirement is an ongoing topic with overwhelming importance for the livestock industry. Dietary supply of nutrients like amino acids to
A concentrate is usually described as a feed or feed mixture which supplies primary nutrients (protein, carbohydrate and fat) at higher level but contains less
Different raw materials are characterised by their amino acid composition. In addition within a specific type of raw material but between different samples, differences in
The Near Infrared Reflectance (NIR) Spectroscopy technique can be used for fast evaluation of the nutritional content of feedstuffs. This method requires a sufficiently large
The nitrogen content of different proteins is relatively constant and varies only slightly from an average value of 16%. The level of protein in a
5.1 Feed specification A nutritionist must define a certain nutrient level of the feed he wants to produce. By reviewing recommendations from different sources, research
Technical processing is used to a great extent in feed production. Protein-containing feedstuffs and compound feeds are treated with steam and heat. For proteins damaged
The most recent data concerning ideal amino acid ratios are based on amino acids digested in the ileum in order to take into consideration the
Isoleucine, leucine and valine are the three branched chain amino acids. Their metabolism is unique, sharing the same catabolism pathway and therefore interfere with each
The animal itself is capable of synthesising about half of the amino acids. These amino acids are termed non-essential amino acids. However, about 10 amino
Protein is not a nutrient. Animals require amino acids and not protein per se. The quality of protein supply is determined by its potential to
Digestion and absorption Amino acids chemically bound in proteins must be separated from the parent protein unit, before they can pass from the lumen of
Amino acids are characterised by the two characteristic functional groups in the molecule, as indicated by their nomenclature, by the amino group NH2 and the
