Resumo: |
The objective of the experiment was to evaluate the feedlot performance of steers with dairy origin, which during the growing phase were supplemented on pasture with two levels of concentrate (high=1% or medium=0,5% BW), and that during finishing were submitted to two concentrate levels (high=80% or medium=50%), resulting into four feedlot treatments, THH, THM, TMH and TMM. Steers from treatments that received higher supplementation level during growth,, were heavier at beginning and stayed less time in feedlot to reached slaughter weight. Average daily dry matter intake (DMI) for TAA was higher than for TMM animals, both not differing from TAM and TMA. DMI expressed as percentage of weight, average daily weight gain and feed conversion were similar among treatments. Animals supplemented with 1% during growing phase showed higher (p<.05) initial thoracic perimeter and lower gain of this measure during feedlot, resulting no difference among treatments at the end. Animals that received lower level of supplement during growing phase had lower rump height at the beginning and showed higher gain for this measure during feedlot. Final rump height was higher (p<.05) for TAM and TMM animals |
