Abstract


The objective was to evaluate the effect of the addition of different commercial brands of ractopamine hydrochloride on diets for finishing pigs, evaluating performance and carcass characteristics. Thirty-six pigs of the commercial strain Dalland, initial weight of 98.74 ± 0.68 kg were used. Experimental design in randomized blocks with three treatments and six replicates per treatment, two animals per experimental plot. Meat samples - control - or supplemented with 10ppm ractopamine from two laboratories were evaluated with 2 ractopamine hydrochloride. Supplementation of 10 mg / kg ractopamine 28 prior to slaughter was found to have improved feed conversion and carcass characteristics.
