Productive performance of Nellore steers in pasture with association of flavomycin and monensin

Abstract

The objective of this work was to evaluate the efficiency of nutrient absorption with the use of additives such as monensin and flavomycin in steers performance. Performance parameters were studied in 111 (one hundred and eleven) uncastrated steers with aged 20 to 22 months and mean live weight of 469.8 kg, divided into two experimental groups: 54 steers Nellore flavomycin (NF) and 57 steers Nellore with flavomycin and monensin (NFM). NFM animals had total weight gain, mean daily gain and percentage gain (p<0.05) higher than NF animals. Therefore, the use of monensin associated with flavomycin in Nellore sows in semi confinement provided a better performance of total and daily weight gain in relation to the use of monensin alone.
