This study aimed to evaluate chromium supplementation on productive, reproductive, and metabolic parameters at lactating Girolando cows subjected to heat stress conditions in a climatic chamber. Thirty-six lactating Girolando cows were subjected to two sequential trials. In trial 1 (thermoneutral environment), the effect of chromium supplementation was evaluated (0 vs. 0.50mg/kg of drymatter). In trial 2, the cows were fed the same diets, but they were divided into three environmental conditions: heat stress conditions in climatic chamber, fed ad libitum (HS); thermoneutral environment, fed ad libitum (TN); and thermoneutral environment, pair-fed (PF). In thermoneutral conditions, chromium supplementation did not affect productive or metabolic parameters, although supplemented cows had lower viability of oocytes (65.11 ± 0.08% vs. 76.86 ± 0.08%). During heat stress, chromium supplementation lowered plasma glucose levels (61.17 ± 1.90 vs. 67.11 ± 1.90 mg/dL), and increased the insulin:glucose ratio (0.39 ± 0.04 vs. 0.27 ± 0.04). Cows fed the control diet in the HS group had higher vaginal temperature values (39.40 ± 0.10 °C) than the cows in the TN group and PF group (38.89 ± 0.10 °C and 38.85 ± 0.11 °C, respectively). However, supplemented cows heat-stressed maintained the same vaginal temperature as cows in thermoneutral conditions. In conclusion, chromium supplementation improved glucose metabolism and prevented body temperature increases under heat stress conditions. |
