Age influences on amino acid intestinal transport.
1. Intestinal absorption of amino acids show a decrease with aging in different animal species such as avians, rodents and ruminants. 2. The different intestinal segments show different absorptive capacities, the jejunum being the most absorbent. 3. Chickens show the biggest capacity for amino acid absorption close to hatching. 4. In rodents the third week seems to be the period of increased transport capacity.
