Abstract

This experiment was conducted in order to investigate The effect of vitamin and mineral supplementation during the transition period of Holstein dairy cows on changes in the hematology of cows and the hematology and immune transmission of their newborn calves born. For this purpose, 32 pregnant cows were selected based on the calving cycle, age, body weight and body condition score and were divided into 4 treatments and 8 repetitions in the form of a completely randomized design. Experimental treatments included: 1) control group , 2) treatment receiving injectable vitamin supplement, 3) treatment receiving injectable mineral supplement and 4) treatment receiving vitamin and mineral supplement injection together. results showed that simultaneous Injection of minerals, vitamins, and simultaneous mineral and vitamin injections increased hemoglobin and monocyte concentrations in cows before calving (P<0.05). In the treatments receiving minerals and vitamins in late pregnancy, an increase in hemoglobin concentration was observed compared to the control group in the postpartum period of cows.IgG and IgM in calves born from mothers receiving vitamins, minerals, and vitamins and minerals simultaneously were associated with an increase on the day of birth, 24 hours after birth, and 30 days after birth (P<0.05), and none of the treatments caused a significant change in IgA of calves at any time. according to the results injection of minerals and vitamins to cows during the transition period leads to better functioning of blood cells and coping with stress and inflammation in cows and improves the immune system in cows and their calves
