Abstract
It is shown that lignosulphonic acids, at a concentration of 13 % in conventional feed given to growing pigs, lead to a marked reduction in the weight gain.
When given 3 % and 6 % lignosulphonic acids in the feed, no effects on the weight gain were observed as compared to the controls.
The weight gain reduction caused by lignosulphonic acids at high levels in the feed is discussed in relation to the inhibitory effects of these acids on a number of biological systems which have been studied previously.
