The plant sea buckthorn (Hippophae rhammoids L.) primarily is valued for its golden-orange fruits which provide vitamins C and E, other nutrients, flavonoids, oils rich in essential fatty acids, and other healthful components with a potent antioxidant activity. The aim of the research was to evaluate the influence of feeding of sea buckthorn by-product premixes on the mare and foal blood biochemical indices. Field trials were carried out at the studhorse farms Burtnieku zirgaudzētava Ltd (in Burtnieku pagasts of Valmiera region) in the year 2007, and at Princis Ltd (in Cenu pagasts of Jelgava region) in 2008, from January to May each year on every farm. For the trials, 15 Latvian pedigree mares in foal were split into three groups (5 mares in a group). All mares were identical for their genetic and production parameters. Control group was fed with farm routine diet, experimental group II was fed with routine diet plus 0.3 kg of dried sea buckthorn leaves and sprigs, but experimental group III was given routine diet plus 0.3 kg of dried berries residues. At the beginning of the trial and after foaling, the blood samples of all mares and foals were analyzed for hematological indices (red blood cell count, hematocrit, leucocytes, etc.), as well as for the content of Mg, Zn, Cu, and units of glutathione peroxidase. In the blood samples of mares after foaling, a disparity (p is less than 0.05) between control and experimental group II, and between control and experimental group III was detected for several indices: red cell distribution width index RWD, reduced count of leucocytes, changed ratio between leucocyte types, reduced count of lymphocytes and monocytes, and increased amount of Zn (mg dLE-1).
