Abstract

In order to investigate the effect of feeding zinc-methionine (Zn-Met) supplement on growth performance, nutrientsdigestibility, ruminal fermentation parameters and some blood metabolites, an experiment was conducted on fifteenKermani male lambs with average initial body weight of 32. 1 ± 0. 88 kg as a completely randomized design with 3treatments and 5 replicates for 8 weeks. The experimental treatments were basal diet without supplemental Zn(Control), basal diet plus 50 mg Zn/kg diet of Zn-Met, and basal diet supplemented with 100 mg Zn/kg diet of Zn-Met. The results showed that lambs fed with 100 mg/kg diet of Zn supplement had lower feed intake than the othertreatments (P<0. 01). Lambs received 50 mg Zn /kg of diet had higher average daily gain than those on control diet(P<0. 05). Lambs fed with Zn supplement (50 or 100 mg/kg) had better feed conversion ratio than the control group(P<0. 05). The apparent DIGESTIBILITY of dry matter, organic matter and neutral detergent fiber (NDF) was higher inlambs fed 50 mg/kg of Zn supplement than those of the control (P<0. 05). However, no difference in fat and aciddetergent fiber (ADF) DIGESTIBILITY was observed between treatments. Additionally, feeding Zn-Met supplementeddiet had no significant effect on pH and ammonia nitrogen of ruminal fluid as well as serum glucose, total protein, triglyceride and urea concentrations of lambs. According to these results, feeding 50 mg/kg diet of Zn supplementincreases feed nutrients DIGESTIBILITY and compared with 100 mg of the supplement, has better effects on growthperformance of FATTENING LAMBs.
