Animal/Poltry Nutrition

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 reports in the scientific literature, and the perspectives gained by personal experience they can establish

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 by heat during processing, the measurement of ileal digestible amino acids gives a better estimation

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 influence of amino acid losses during digestion and absorption. Further data for individual species can

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 other. Leucine is a strong regulator of the branched chain amino acid catabolism. As a

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 acids (depending on the species) can not be synthesised by the animal and a source
