Abstract: The experiment was conducted to study the effect of magnetized water on the growth performance, digestion metabolism and slaughter performance of lamb.12 weaned male lambs with average body weight of 5.57 kg±0.36 kg were selected and randomly divided into 2 groups, 6 lambs in each group.2 groups were provided with the same basal diet while lambs in experiment group were given with magnetized water (MW), and that in control group were given with normal water.The digestion metabolism experiments were carried out at 95-110 days and 215-230 days, respectively, and the slaughter performance of lamb was determined at 240 day to study the effects of drinking MW on the growth performance, digestion metabolism and slaughter performance of lamb.The results showed that in the earlier phase, comparing with control group, dry matter voluntary intake and the apparent digestibility of dry matter, organic matter, crude protein, cellulose, hemi-cellulose, calcium and phosphorous of lambs in MW group at 95-110 days were increased by 25.5% (P>0.05), 15.2% (P>0.05), 14.4% (P<0.05), 13.5% (P<0.05), 66.3% (P<0.05), 52.3% (P>0.05), 16.4% (P<0.05)and 1.3% (P>0.05), respectively.In the later phase, that of MW group were increased by 15.3% (P>0.05), 9.0% (P<0.05), 8.8% (P<0.05), 7.7% (P<0.05), 20.6% (P<0.05), 33.5% (P<0.05), 9.8% (P<0.05) and 14.5% (P<0.05), respectively.During 20-220 days, the average daily body weight gain of lambs in WM group was increased by 40.8% (P<0.01)and the live body weight, carcass weight, carcass net meat percentage, carcass lean weight were increased by 40.8% (P<0.01), 52.3% (P<0.01), 8.8% (P<0.01) and 66.2% (P<0.01), respectively.In conclusion, the digestibility of nutrient and daily body weight gain of lamb could be increased and the slaughter performance of lamb be improved to a certain degree by drinking MW.
