Effect of dietary boron on physiological responses in growing steers inoculated with bovine herpesvirus type-1
چکیده انگلیسی

Thirty-six Angus and Angus × Simmental steers were fed one of three dietary treatments; (1) control (no supplemental B), (2) 5 mg supplemental B/kg, and (3) 15 mg supplemental B/kg for 47 days to determine the effects of dietary boron (B) on disease resistance following an inoculation with bovine herpesvirus type-1 (BHV-1). On day 34 of the study steers were inoculated intranasally with BHV-1. Rectal temperatures began to elevate at day 2, and plasma tumor necrosis factor-α concentrations increased (P < 0.05) by day 2 following BHV-1 inoculation. Plasma acute phase proteins were increased (P < 0.01) while plasma interferon-γ was decreased (P < 0.05) by day 4 post-inoculation. Supplementation of B increased (P < 0.001) plasma B concentrations in a dose-responsive manner. However, dietary B did not affect the duration and severity of clinical signs of BHV-1 and had minimal effects on plasma acute phase proteins and cytokines.
