摘要
A series of experiments was carried out to determine the effects of chelated minerals on the performance of pigs and chickens. Copper chelated with methionine was more-effective in improving weight gain and feed intake of both pigs and chickens compared with copper sulfate. Methionine-Cu chelate at the level of 100 - 150 ppm in Cu may be adequate. Methionine-Zn chelate was more effective than ZnO in improving pig performance. One to two hundred ppm of Zn in the form of methionine chelate showed highest weight gain and feed intake but a high dietary level of Zn (1,000 and 2,000 ppm) in the form of methionine chelate had a diminishing effect on weight gain and feed intake. Iron in the form of methionine-Fe chelate was more effective than CuSO4. 5H(2)O in increasing Fe content in the yolk. The increase of Fe in the egg yolk plateaued approximately 10 days later.
