An experiment was conducted to evaluate the effect of different copper sources on broiler performance, intestinal morphology and liver copper contens using 200 one-day old Cobb 500 male chicks randomly distributed into five groups of 40 chicks each. Each group received, during 40 days, one of the following dietary treatments: T1, basal diet containing antibiotic (positive control); T2, basal diet without antibiotic (negative control), T3, as T2 + 250 ppm Cu from tribasic copper chloride. The results showed that final body weight, body weight daily gain, feed benefit-cost ratio and carcass yield were not significantly influenced (P>0.05) by the dietary treatments. The lowest feed intake and the best feed efficiency were observed in the copper sulphate-supplemented group but the latter was not different of the two other copper sources. Copper content in livers from broilers that were fed the tribasic copper chloride- supplemented group was significantly higher (P<0.05) than the ones that were on other treatments. With regards of the intestinal morphology, treatments than contained supplemental copper tended to influence villus width in the caudal duodenal area and villus height in the jejunum area. It is concluded that the supplementation with 250 ppm Cu from copper sulphate improved feed efficiency and that intestinal morphology was influenced by the copper supplementation regardless the source.
