摘要：

The present study is designed to investigate the growth promoting effect of rare earth elements often described in the Chinese literature in piglets which were fed under western conditions. A total of 72 piglets were allotted to five dietary treatment groups which include a control group, two REE groups with low and high content of LaCl3, two REE groups with low and high content of an REE mixture containing mainly chlorides of La, Ce and Pr. The feeding period lasted five weeks. Positive effects of REE were found on both weight gain and feed conversion of the pigs. Compared to the control group, the weight gain of piglets in different REE groups increased by 2 to 5%. The feed conversion improved by up to 7%. At the end of the feeding experiment the pigs were slaughtered and the organs were analysed for REE content. This is the first time that growth promoting effects of REE have been shown under western conditions, however more detailed studies are needed to understand the mechanism of REE promoting effects.
