Abstract
Abstract
The objective of this study was to determine the effects of some antioxidant vitamins and trace elements on some metabolic and postpartum reproductive profiles in dairy cows during transition period. In the study, altogether 20 clinically healthy Brown Swiss dairy cows (aged 4-5 years-old) under the same management and feeding conditions in periparturient period were used. The animals were divided into two equal groups: control (C) and treatment (T) group (n=10 for each group). Vitamins (A, D, E) and trace elements (Cu, Mn, Se, Zn) were administered intramuscularly into the cows of the T group, while isotonic saline, as placebo, was injected subcutaneously into those in the C group. Blood samples were collected by venipuncture of the jugular vein at the beginning of transition period, parturition and 3-weeks after the parturition. The metabolic and reproductive parameters were determined. In the C group, statistically significant changes were observed in the levels of non-esterified fatty acids (NEFA), high density lipoprotein (HDL), low density lipoprotein (LDL), total protein (TP) (p<0.05), glucose (GLU), progesterone (P4) (p<0.01), total cholesterol (T.CHOL), triglycerides (TG), UREA, creatinine (CRSC) and total bilirubin (TBIL) (p<0.001). In the T group, significant changes in the levels of NEFA, TBIL (p<0.05), T.CHOL, HDL, LDL (p<0.01), TG, GLU, P4, TAC and TOC (p<0.001) were observed. It was concluded that the administration of various vitamins and trace elements could be effective to improve some metabolic and reproductive profiles in dairy cows during the transition period.
