Determining the influence of chromium propionate and on growth performance and carcass composition of pigs housed in a commercial environment.

Two experiments were conducted to determine the effects of feeding chromium propionate (Cr; Kemin Industries, Inc., Des Moines, IA) and a -based extract (YS; Distributors Processing, Inc., Porterville, CA) on growth performance of finishing pigs housed in commercial conditions.

Influence of chromium propionate dose and feeding regimen on growth performance and carcass composition of pigs housed in a commercial environment.

Although chromium (Cr) feeding study results have been variable, our hypothesis was feeding a regimen that changed dosage over time would result in a larger positive response in growth performance and carcass characteristics. In Exp. 1, a total of 1,206 pigs (PIC 337 × 1050, initial BW 28.
