Abstract |
The present study was conducted to assess the effect of short term
starvation on galanin, leptin, thyroid hormones, insulin, prolactin,
growth hormone, ghrelin and factors involved in energy metabolism
including high-density lipoprotein (HDL), cholesterol, β-hydroxybutyrate,
glucose, non-esterified fatty acids (NEFA), triglyceride (TG) and
very-low-density lipoprotein (VLDL) concentrations in adult goats. Eight
non-lactating non-pregnant goats aged 4-5 years and body condition score
(BCS) 3 were randomly assigned to control and test groups. The animals
were trained to eat their daily forage ration during a period of 10
days. The experimental procedure was applied for 3 days during which
control group received 120% of maintenance energy, while the test
group was supplied with 60% of maintenance energy. Blood samples were
collected on days 8 and 10 and at 2, 12, 24, 36 and 72 hours after
beginning of starvation. Blood parameters were measured according to
standard procedures. No significant differences were observed in the
concentrations of cholesterol, fT3, fT4, glucose,
growth hormone, leptin, VLDL-cholesterol, non-esterified fatty acids
(NEFA), triglyceride (TG) and prolactin between control and test groups.
A significant difference was found in β-hydroxybutyrate concentration
between fed and fasted goats at 36th hour of starvation.
Moreover, there was a significant difference in the concentration of
HDL-cholesterol between control and test groups at 72nd hour
(P<0.05). Gradual starvation had no effect on hormonal and neuropeptides
concentrations probably.
