Metabolic effects of fasting in steers

J W Blum et al. Res Vet Sci. 1981 Jul.

Abstract

The effect of starvation for five days on blood levels of various hormones and metabolites was studied in seven steers. There was a significant decrease (P less than 0.05) in thyroxine (free and total), 3,5,3'-triiodothyronine (free and total), immunoreactive insulin, propionic acid, butyric acid and glucose, 3,3',5'-triiodothyronine and alpha-aminoacid-N levels did not change. Free fatty acids, beta-hydroxybutyrate, acetoacetate, urea, isobutyrate, alpha-methylbutyrate and isovalerate, total protein and albumin significantly (P less than 0.05) increased.
