Feed Grade Chromium Picolinate Cas 14639-25-9

Product Description: Feed Grade Chromium Picolinate Cas 14639-25-9 Chromium is an essential nutrient (trace element), existing in many tissues and organs in human and animals. Playing a role as GTF-Cr, chromium participates in various metabolisms by enhancing the efficiency of insulin, such as carbohydrate, fat and protein metabolisms. The chromium is rare in ordinary animals diet, and most in inorganic forms with poor efficacy. In order to avoid the chromium deficiency, addition of organic chromium into diets is proved to be the best way to satisfy chromium demand of animals growth. Feed with organic chromium can lead to below benefits for animals:            Improve animals growth performance, particular under stress conditions.            Reduce feed conversion rate, saving feed cost            Enhance animals immunity and reproductive performance.
