Some hormonal disturbances have been demonstrated in starvation, but in ruminants such as goats, the role of galanin in adaptation to starvation or endocrine functions is not well studied. The present study was conducted to assess the effect of long term starvation on galanin, leptin, thyroid hormones, insulin, prolactin, growth hormone, ghrelin and factors involved in energy metabolism including HDL, Cholesterol, β-hydroxybutyrate, glucose, NEFA, TG and VLDL concentrations in adult goats. Eight non-lactating non-pregnant goats aged 4-5 years and BCS 3 were randomly divided to control and test groups. The animals were trained to eat their daily forage ration during a 10 day period. The experimental procedure was applied for 20 days, during which control group received 120% of maintenance energy, while the test group was supplied with 80% of maintenance energy for the first 10 days and with 40% of maintenance energy for another 10 days. Blood samples were collected at day 10 of training and 2, 4, 10, 12, 14 and 20 days after beginning of starvation. Blood parameters were measured according to standard procedures. No significant difference was observed in the concentrations of cholesterol, fT3, T4, T3, growth hormone, NEFA, insulin and ghrelin between control and test groups (P=0.05). There was significant difference in galanin, leptin, fT4, HDL, glucose, TG, VLDL and prolactin concentrations between control and test groups (P=0.05). Control of energy balance and the role of galanin in adaptation to long starvation or endocrine functions in goat are different from other species.
