Implication probiotic, phytobiotic and their complex on the mineral composition of blood serum calves

Determination of morphological and mineral composition of blood of calves on the basis of serum analysis is one of the modern diagnostic indicators of physiological state of the organism. On the basis of experimental data the changes in morphological and mineral composition of blood of six-month-old calves of Simmental breed were analyzed when phytobiotic, probiotic “SBT-Lacto” and their complex were included in the feed ration. Within the framework of the performed research the change of morphological indicators (hemoglobin, erythrocytes, leukocytes content) and mineral indicators (magnesium, iron, copper, zinc content) was studied. In the course of the study it was revealed that the greatest influence on the morphological composition of blood of calves had the inclusion in the feed ration of a complex of phyto-additives in the form of thyme extract and probiotic “SBT-Lacto”. Thus, the complex of probiotic and phytobiotic increased hemoglobin content by 8.4%, erythrocytes by 17.9% and leukocytes by 13.6% in relation to the control group with traditional feed ration. The results of the study showed that the inclusion of phytobiotic in the feed ration increased the level of iron in the blood: 43.72 ± 0.41 mg/%, which is 5.7% higher compared to the index of calves of the control group. The addition of probiotic to the feed ration of calves increased the content of magnesium, copper, manganese and zinc in relation to mineral indices of other experimental groups and control group. In turn, the inclusion of probiotic and phytobiotic complex in the feed ration increased such indicators as hemoglobin, erythrocyte and leukocyte content by 9.2 g/%, 21.8 × 1012/l and 15.8 × 109/l, respectively, compared to the control
