Abstract:
Minerals play an essential role in the normal vital process.Calcium, phosphorous and magnesium are the most abundant minerals. Vitamin D and parathyroid hormone play a key role in regulation of their homeostasis as well. The aim of this study was to evaluate calcium, phosphorous, magnesium, vitamin D and parathyroid hormone on 30 Caspian horses of Guilan Province (south of the Caspian Sea) in two different seasons. So that, 15 stallions and 15 mares were sampled at the age groups ≤ 3 years and > 3 years respectively. Fasting blood samples were collected twice, in August and January 2015 from jugular vein of horses. Serum calcium, phosphorous and magnesium were measured by colorimetric methods, while 25(OH)D3 and parathyroid hormone were measured by ELISA. The calcium (11.50 vs. 14.25 mg.dL-1), magnesium (2.13 vs. 3.72 mg.dL-1) and vitamin D (1.66 vs. 2.48 ng.ml-1) levels were lower in winter than in summer (P 3 year - old ones (P
