Abstract
1. Rates of entry of alanine and glycerol and their contribution to glucose synthesis were studied in 48‐h fasted White Leghorn cockerels using primed constant intravenous infusions of L‐[U‐14C]alanine and [U‐14C]glycerol.
2. Entry rates of alanine and glycerol were 112 and 401 μmol/h per kg body weight, respectively.
3. Of the total glucose irreversible loss (entry rate), 1.5 and 6.6% were derived from alanine and glycerol, respectively.
4. The possibilities of the operation of a glyoxylate cycle and ω‐oxidation of fatty acids in the fasted chicken are discussed.
