Ghrelin is a multifunctional regulatory peptide that has widespread endocrine and metabolic effects in mammals and birds. The present study aimed to investigate the possible effect of ghrelin on blood hormone and biochemical indices in turkey. A total of forty-eight 28 day-old turkeys were divided into three groups for tests. Ghrelin was injected at the onset of the experiment (28-day old birds). Treatment doses were as follows: treatment 1 (control) without injection; treatment 2-50 ng ghrelin/kg body weight (BW); and treatment 3-100 ng ghrelin/kg BW. Two blood samples were taken from the birds, one at 12 h (short-term effect) and the other at 40 days (long-term effect). Blood analyses showed that level of corticosterone increased in response to ghrelin treatments G50 and G100 in samples taken on days 28 and 68 (p < 0.01). There was an increase in T-4 concentration in the G50 and G100 groups in comparison with the control. Blood glucose increased in response to ghrelin administration, and total cholesterol and triglyceride concentrations decreased in the two samples in response to higher ghrelin dosage (p < 0.01). In conclusion, the peripheral administration of ghrelin in turkeys may increase levels of serum corticosterone, glucose and T-4. Therefore, total cholesterol and triglyceride may decrease in birds following ghrelin administration. Ghrelin may increase metabolic rate (due to increases in T4) and regulate lipogenesis in poultry species such as turkey.
