摘要

A study was conducted to investigate the effect of feeding complete feed as total mixed ration (TMR) with two levels of zeolite on copper (Cu), iron (Fe), and zinc (Zn) status and rumen color of growing Naemi lambs. Twenty-four growing lambs (25 +/- 2.1 kg body weight) were individually kept in separate pens with ad libitum feed and water. The lambs were randomly distributed to three treatments as follow: control, TMR diet only; T1, TMR with 1% zeolite daily; T2, TMR with 2% zeolite daily. The trial was lasted for 56 days. Four lambs from each treatment were slaughtered and tissue (liver, kidney, meat, and rumen tissues) and rumen fluid samples were collected. A significantly (P < 0.05) high concentration of Fe was found in T2 in blood and rumen fluid samples of lambs supplemented with zeolite. In the meat tissue, significantly (P < 0.05) high concentration of Zn was found in the treatment groups compared with the control, while Cu concentration decreased significantly (P < 0.05) in T1. In addition, rumen dark color was reduced in the zeolite-supplemented groups. We concluded that supplementation of zeolite at the rate of 1 or 2% did not appear to have any adverse effects on the blood profile of trace elements. Moreover, under these two levels of zeolite, discoloration of the rumen was significantly reduced in response to the supplementation of zeolite.
