![]() ![]() Observation suggests that chromium can affect blastogenic activity by alteringĬytokines production during the early stages of peripheral blood mononuclear Unsupplemented cows in one or more of four sample times during the trial. Gen-stimulated mononuclear cells from chromium-supplemented cows than from They observed lower concentrations of interleukin-Ģ, interferon-y, and tumor necrosis factored in the culture supernatants of mito. (1996) conducted a subsequent study toĭetermine whether chromium affected cytokine production by activated periph-Įral blood mononuclear cells. Supplemental chromium had greater mitogen-stimulated blastogenic responsesīy peripheral blood mononuclear cells prepartum and at calving than did those ofĬontrols, also indicating a greater cell-mediated immune response because ofĬhromium supplementation. Tal chromium influences production of IgG, but not IgM antibodies. To human red blood cells were not evident. Response profiles than did unsupplemented cows. The chromium-supplemented cows had greater antiovalbumin antibody Humoral immune responses wereĪssessed by measuring antibodies either to ovalbumin or to human red bloodĬells. Mg/day for the first 16 weeks of lactation. Twenty cows fed a basal diet containing an unspeci-įied quantity of chromium were compared with those fed 5.5 mg supplementalĬhromium per day as chelated chromium for 6 weeks before calving, and 9.98 Results of a study with periparturient and early-lactation dairy cows indi-Ĭated that chromium supplementation influences the immune response in stressedĬattle (Burton et al., 1993~.
