Resumen
Descripción
The objective of this study was to assess the correlations of amylin (a pancreatic polypeptide hormone) with some hormonal, biochemical and bone parameters in pullets. Forty 18-week-old pullets were used. Plasma amylin, CT (calcitonin), 1,25 (OH)2 vitamin D (1,25 dihydroxycholecalciferol ), serum osteocalcin, glucose, ALP (alkaline phosphatase), cholesterol, and triglycerides, as well as weight, length and total volume of tibiotarsi were measured. Plasma amylin concentration was negatively correlated with serum cholesterol (p<0.05) and triglycerides (p<0.05) concentrations. Plasma amylin concentration was significantly and positively correlated with plasma calcitonin concentrations (p<0.001). Serum ALP and plasma amylin concentrations were positively correlated (p<0.01). There were no correlations between amylin hormone and other parameters. Based on these results, it is possible to conclude that endogen amylin may effect cholesterol, triglycerides, calcitonin, and ALP levels in pullets without changing some other hormonal, biochemical and bone parameters related to calcium and lipid metabolism.
