dc.descriptionThe purpose was to estimate the liquid requirements of Zn, Fe, Mn and Cu for weight gainin 46 castrated Canindé goats in grazing system in the Caatinga supplemented with 0, 0.5, 1 and 1.5% levelsin relation to live weight. The animals had an initial average body weight of 15.76 ± 0.96 kg. Six animalswere slaughtered at the onset of the experiment (16.1 ± 1.15 kg BW) and the rest (n = 40) were randomlydistributed into one of the four levels of supplementation. The body composition (mg kg-1 EBW) variedfrom 8.47 to 9.09 mg Zn, 13.54 to 13.77 mg Fe, 6.34 to 6.36 mg Mn and 3.78 to 5.10 mg Cu, for Canindégoats with 15 and 25 kg BW, respectively, and the liquid requirements for gain (mg kg-1 BW gain) wereestimated by the comparative slaughter method, and varied from 6.98 to 7.77 mg Zn; 10.20 to 10.72 mg Fe;4.64 to 4.82 mg Mn and 4.28 to 5.96 mg Cu for the animals with BW varying from 15 to 25 kg,respectively. The liquid requirements of microminerals estimated in this research were inferior to therecommendations made by international committees.
