The goal of the present study was to investigate the daily rhythms of calcium, phosphate and 1,25-dihydroxyvitamin D3 (1,25-(OH)2 D3) in the blood serum of goats. Blood samples from six Girgentanabreed goats were collected via an intravenous cannula inserted into the jugular vein at four-hourintervals over a 48-hour period (starting at 08:00 hours on day 1 and finishing at 04:00 on day 2). Theserum concentration of calcium and phosphate was measured by photometric test and of 1,25-(OH)2 D3by HPLC. All parameters were expressed as mean ± SEM. The one-way repeated measures analysis ofvariance (ANOVA) was used to determine significant differences. ANOVA showed a highlysignificant effect of time in all the parameters studied.. The application of the periodic model and thestatistical analysis of the Cosinor enabled us to define the periodic parameters and their acrophases(expressed in hours) during the 2 days of monitoring: all the studied parameters exhibited diurnalacrophases, which were within 12:44 and 17:28 hours. The results obtained led us to reveal theexistence of a daily rhythm for the parameters considered and their temporal physiological values areuseful for their implications in the formulation of therapeutic and nutritional protocols in the goat. |
