Biochemical adaptation of camelids during periods where feed is withheld
Biochemical changes during fasting or the withholding of feed for 5 day were studied in serum of camelids (dromedary camel, llama) and ruminants (sheep, steers). Camels maintained low levels of 13-hydroxybutyrate (BHB) and high levels of glucose but showed some increased levels of non-esterified fat...
