Abstract
With the increase in the global herd, the use of metabolic modifiers has become an important area for many researchers looking for a supraphysiological diet to improve production parameters. For improving the performance of high yielding cows, the optimal balance of all nutrients including microminerals is important. Chromium (Cr) is one of the important micronutrients which plays an important role in metabolism of ruminants. Experimental studies have found that Cr could change performance, immune responses, glucose and fatty acid metabolism, and antioxidant status in dairy cows. In some studies, Cr supplementation improved dry matter intake, milk production, and milk composition of dairy cows in the early, mid, or late stage of lactation. Also, in some studies, performance of growing animal, immune response, and some blood parameters responded positively to Cr supplementation. In conclusion, the effects of Cr supplementation on performance of ruminants are inconsistent; however, its long-term effects on health, productivity, immune system, and antioxidant activity of ruminants still need to be investigated.
