The experiment was carried out aiming at evaluate the effect of using ractopamine and phytase in diets for swines at the end of the finishing period on performance, carcass characteristics and mineral composition on the third metacarpus bone. It was used 240 barrows with initial weight 100.7 ± 3.9 kg in a random block design, in a 2 × 3 factorial arrangement, with two levels of ractopamine (5 ppm and 10 ppm) and three levels of phytase (0, 500, and […]

The objective of this study was to evaluate the effects of ractopamine and enzyme phytase on the performance and carcass characteristics of finishing pigs. Three hundred and fifty-four commercial type barrows were used from a single source with 94.1 ± 5.7 kg initial body weight in a randomized complete block design, with six treatments and five replications with 11 or 12 animals per experimental unit evaluated. The following feeds were: control diet based on tables of nutritional requirements; (A) diet […]
