Re: Donkey or Burro Blood vs. Horse Blood

The horse blood is yellow because horses have much higher levels of
bilirubin than donkeys.

This is from an article by Susan Dugat in Journal of Equine Veterinary
Science:

Reference ranges for triglycerides, insulin, cortisol, and
adrenocorticotropic hormone (ACTH) are used in diagnosing
hyperlipemia and pituitary pars intermedia dysfunction
(PPID) in the donkey. Values are currently
compared to reference ranges of the horse so as to diagnose
disease. Previous studies found differences between
hematological, serum biochemical, and hormone values
of the horse and donkey. We suspected that similar differences
existed between horse and donkey triglyceride,
insulin, cortisol, and ACTH levels. Blood samples were
drawn from 44 healthy mammoth donkeys and 1 miniature
donkey, ranging in age from 3 weeks to 21 years, and
varying in sex and pregnancy status. All but one donkey
scored 3 of 5, ‘‘ideal,’’ body condition scoring.
Samples
were tested for triglycerides, insulin, cortisol, andACTH
levels. Amarked difference was found between horse and
donkey normal values for triglycerides, insulin, and
ACTH. The mean values and standard deviation in the
tested population were 66.4  34.2 mg/dL for triglycerides,
2.1  2.05 mU/mL for insulin, and 66.7 
20.7 pg/mL for ACTH. The reference ranges in the
horse are 14â€"77 mg/dL for triglycerides, 4.9â€"45.5
mU/mL for insulin, and 18.7  6.8 pg/mL for
ACTH. Cortisol levels were similar in the two species,
a 4.0  1.2 mg/dL for donkeys being within the reference
range for the horse, 2.9â€"6.6 mg/dL. Values were
not correlated to age. The sample size prevented us
from determining any correlation according to sex or
pregnancy status. Differences between horse and donkey
triglyceride and ACTH values may be significant for
accurately diagnosing and treating hyperlipemia and
PPID, respectively, in the donkey.
===========================

So, ACTH much higher in those donkeys.
