“…Others, however, have reported no positive effect on these same traits (Liarn, 1993;Ward et al, 1993;Ward and Southern, 1995;Kim et al, 1996a,b;Anandhi et al, 2006). Researchers reported that Cr supplements may decrease carcass fat (Kim et al, 1996a) or plasma cholesterol (Press et al, 1990;Kitchalong et al, 1995;Kim et al, 1996b) of broiler chickens. In the majority of the previous studies, chromium picolinate (Kim et al, 1996a,b), Cr yeast (Hossain et al, 1998) or CrCl 3 (Uyanik et al, 2002) have been used, and there has been no research in broilers with chromium polynicotinate.…”
