This study evaluated the effect of ractopamine (RAC) on the performance of finishing pigs and the meat quality of these animals. Seventy crossbred pigs (35 barrows and 35 females) selected for high gain of lean meat, with initial weight of 77.1±0.32 kg were distributed in randomized blocks with five treatments (0, 5, 10, 15, and 20 ppm RAC in the diet) and seven replications during 28 days. The experimental unit was represented by a male and a female pig. Regarding […]

An experiment was carried out using 468 gilts, with an initial weight of 84.77 ± 7.20 kg and allotted into 36 pens to evaluate the effect of the addition of ractopamine in the diets on performance, characteristics and yields of carcass comercial cuts, composition and retail cuts of ham. It was used a randomized block design with four levels of ractopamine (0, 5, 10 and 15 mg/kg of diet) and nine replicates with 13 animals per experimental unit. The initial […]
