This study was conducted to exploit ameliorative effect of additional vitamin E and/or zinc supplementation on immune response of peripartum Sahiwal cows. Thirty-two pregnant dry Sahiwal cows were blocked into four treatment groups (n = 8), namely control, zinc (Zn), vitamin E (Vit E) and zinc + vitamin E (Zn + Vit E). Feed ing regimen was same in all the groups except that the Sahiwal cows in the zinc-, vitamin E- and zinc + vitamin E-fed groups were additionally supplemented with 60 mg Zn/kg DM, 1000 IU vitamin E and 60 mg/kg + 1000 IU Zn + vitamin E, respectively, from day 60 pre-partum to day 90 post-partum. Blood samples were collected on days 60, 45, 30, 15, 7, 3, 0, 3, 7, 15, 30, 45, 60, 90 and 120 with respect to day of parturition and analysed for total immunoglobulin (TIG), immunoglobulin G (IgG), interleukin-2 (IL-2), vitamin E (Vit E) and zinc (Zn) status. Before calving, cows showed a decrease in plasma TIG, IgG, IL-2, Vit E and Zn levels. However, increased levels of plasma TIG, IgG, IL-2, Vit E and Zn were observed after calving. After calving, Sahiwal cows supplemented with Zn + Vit E had higher plasma TIG, IgG and IL-2 in comparison with cows of control and Zn + Vit E-fed groups. In the present study, plasma vitamin E level was higher in Vit E-fed and Zn + Vit E-fed cows; however, zinc level was higher in Zn- and Zn + Vit E-supplemented cows. In conclusion, a reduced immune response during peripartum period in Sahiwal cows was ameliorated by dietary vitamin E and zinc supplementation. Not Available |
