Effects of Source and Level of Added Chromium on Growth Performance of Starter Pigs
Kansas State University Swine Research. A 35-d growth trial was conducted with weaned nursery pigs to evalu- ate the efficacy of supplemental chromium (Cr) as either chromium nicotinate (CrNic) or chromium picolinate (CrPic). Neither source nor level of supplemental Cr had any effect on weanling pig growth performance or immune status. Equal levels of CrNic and CrPic produced similar results, except that pigs fed CrPic had higher serum Cr concentrations than pigs fed CrNic. These data suggest no beneficial responses to supplemental CrNic or CrPic in nursery pig diets.
