Determination of Protein Digestibility in the Growing Pig

  • Chapter
  • First Online:
Nutritional and Physiological Functions of Amino Acids in Pigs

Abstract

The cost of feed is usually the most significant variable cost in modern intensive pork production, and protein is the most expensive component of the diet. There is thus a considerable financial incentive to maximise the efficiency of utilisation of the dietary amino acids, and especially the dietary first-limiting amino acid. The dietary first-limiting amino acid for the weaned and growing pig is often lysine. It is particularly important that the supply of dietary amino acids to the body tissues (i.e. absorbed amino acids) closely matches the amino acid requirements of the tissues for protein synthesis, to avoid unnecessary wastage.
