Chromium and energy restriction as substitutes for ractopamine in finishing gilts diet/Cromo e restricao energetica em substituicao a ractopamina na dieta de leitoas em terminacao tardia

This study evaluated chromium supplements and energy restriction as substitutes for ractopamine in the diets of late finishing gilts. Sixty gilts were used, with initial weights of 98.87 [+ or -] 0.25 kg and final weights of 122.69 [+ or -] 10.97 kg, distributed in a randomized block design with fiv...

Zusammenfassung:This study evaluated chromium supplements and energy restriction as substitutes for ractopamine in the diets of late finishing gilts. Sixty gilts were used, with initial weights of 98.87 [+ or -] 0.25 kg and final weights of 122.69 [+ or -] 10.97 kg, distributed in a randomized block design with five diets: control; yeast chromium (0.8 ppm); chromium picolinate (0.48 ppm); ractopamine (20 ppm) and energy restriction (reduction of 150 kcal of EM [kg.sup.-1] offeed), with six replicates and two animals per experimental unit. Feeding diet containing ractopamine enabled better (P
