  ABSTRACT: Background: The withdrawal of ractopamine from swine production, demanded by both export and local markets, represents a challenge for the swine industry. This study evaluated the effect of AO NATURAL FIT PRO® as an alternative to ractopamine on the carcass characteristics of finishing pigs. Methods: Thirty-two castrated male pigs (62 ± 2.5 kg initial weight) were randomly assigned to four treatments: control, AO NATURAL FIT PRO® for 8 weeks, ractopamine 10 ppm for 5 weeks, and a combination of both additives. Carcass characteristics were evaluated in all groups. Results: The supplemented groups showed significant improvements (P Conclusions: AO NATURAL FIT PRO®, ractopamine, and their combination improved carcass characteristics without compromising the nutritional quality of the meat. The natural additive represents a viable alternative to ractopamine for optimizing pork quality.
