The net income of each fattening pig of the test groups was increased by 25.26,47.40,9.62 and 4.04 yuan respectively more as compared with the control group.The result showed that the application of the rare- earth feed additive can effectively gain in weight of piglets and increase financial benefit in production of pigs.Adding 15 ppm rare-earth additive in the ration of piglet is well suitable for piglets.
