Abstract
In a preceding trial, the growth hormone concentrations in the serum of zinc-deficient rats were greatly reduced compared to thead libitum- fed control animals. The same reduction, however, was also noted in the case of the pair-fed control animals with strongly diminished feed intake. Therefore, it was not possible to distinguish between the effects of zinc deficiencyper se and the effects resulting from restricted feed intake.
A new study with 136 young male Sprague-Dawley rats showed again that zinc deficiency as well as strongly restricted feed intake reduced the growth hormone content in the serum. But in a marginal zinc deficiency status, when feed intake was only slightly or not reduced, there were lowered serum growth hormone levels in comparison to pair-fed control rats. A 1-wk zinc repletion did not increase the serum growth hormone content of the rats to a normal level, although the serum zinc concentration was normalized.
