Popis:	A study was conducted to determine the effect of sources and levels of zinc on tissue zinc concentration and the carcass quality of broilers. A total of 6,000 1-day-old unsexed broiler chicks were allotted randomly to four floor pens with 1,500 birds per pen. A corn-wheat-soybean meal basal diet (Control) was formulated, and 40 ppm inorganic zinc (40 IZ), 40 ppm organic zinc (40 OZ), and 80 ppm organic zinc (80 OZ) were added to the basal diet to form four dietary treatments. During the 4-wk experimental period, feed and water were provided ad libitum. At the end of the feeding trial, five birds from each pen were randomly selected as five replicates, slaughtered and carcass evaluation was performed. Results showed that zinc supplementations have no effect on zinc content in thigh muscle but a significant increase was found in skins from broilers in 80 OZ ( P
