Effects of Dietary Chromium Supplementation During Late Lactation on Productive Performance, Milk Composition, and Immune and Antioxidant Responses in Dairy Cows.

ABSTRACT: The study evaluated whether organic chromium supplementation in the diets of Jersey cows in the final third of lactation has positive effects on productive performance and milk quality, as well as markers of metabolism, hematology, immunological, and oxidative response. We used 22 cows in a 56-day study, divided into two groups: control (n = 11) and chromium treatment at 10 mg/kg of dry matter per day (n = 11). We evaluated these animals' productive performance markers (milk production, feed intake, and lactation persistence), milk quality (composition and somatic cell counts), and blood biomarkers to assess animal health. Chromium concentration at the beginning of the experiment was within normal limits for the animal category (221 to 246 nM). The cows' consumption of organic chromium inc
