Özet

Vitamin A, calcium (Ca), phosphorus (P) and magnesium (Mg) are essential components for the health and reproductive yield of dairy cows. In this study, it is aimed to profile the calcium, phosphorus and magnesium elements together with vitamin A, which are important components in cattle bred and reared in Northern Cyprus. To analyse these parameters, 260 clinically healthy animals, at least 30 from each region, were blood sampled from eight different regions (Nicosia, Gecitkale, Vadili, Famagusta, Iskele, Ziyamet, Morphou and Kyrenia) during both summer and winter seasons. Vitamin A, calcium, magnesium and phosphorus concentrations were measured from blood samples. Vitamin A levels increased significantly only in Nicosia and Ziyamet regions during the winter season, while there was no seasonal difference from the other regions. Calcium and phosphorus levels were higher in summer when compared with winter. Magnesium levels were significantly higher in winter than in summer. In the comparison between regions in summer and winter, the change in P and Mg values was significant, whereas Ca only showed inter-regional differences during winter. In conclusion, all the parameters found were within the expected ranges but affected by seasonal changes. Therefore, we think that calcium and phosphorus supplementation in winter and vitamin A and magnesium supplementation in summer will provide positive results on cattle.
