17/05/2017: Cut indigestible protein and do piglet health a favor

One of the most important parameters when evaluating feed ingredients is the digestibility of the nutrients they contain. 

Published in nutrition guides, these digestibility values are often used in research projects to verify published data or to shed light on new hypotheses – and they are of key importance when formulating feed for each stage of an animal’s life.

However, another equally important parameter often receives less attention. That is the amount of undigested nutrients in feed and their effect on animal health. Due to the comparative vulnerability of their gut, piglets are of particular interest in this regard.

Major feed nutrient 

Protein is among the nutrients that both have an easily digestible part and a fraction that passes through the digestive tract without being absorbed.

As the most expensive of the major nutrients in feed, it is critical to feed manufacturers and farmers that the protein they use is as digestible as possible. Financial considerations aside, undigested protein is also a potential cause of gut health problems – and it costs energy when nitrogen from deaminated amino acids is removed and excreted via the liver and kidneys.
