Abstract

Thirty-two Nelore heifers (208.3kg) were allocated into 16 pens (two/pen) in randomized design, analyzed as split-splitplot. The treatments with salt or mineral mixture were considered plot, with or without intrauterine devices as split plots and periods as split-split plots. The concentrated ration participated with 40% of the total dry matter offered. There was no effect of the treatments (P > 0.05) on live weight gain or carcass yield. Apart from treatments, a compensatory growth (P < 0.05) occurred in the first period when compared with the other three experimental periods. There was no difference (P>0.05) between animals using intrauterine devices and control groups.
