Abstract

A crude extract with a high proportion of pectic substances was prepared from rye. This was fed to chicks in two studies to determine if rye pectic substances are responsible for the growth depression of chicks fed rye. The growth of chicks was significantly (P greater than .01) depressed when fed a diet containing this extract. Addition of penicillin to the diet improved the growth of chicks. Increasing the concentration of the extract in the diet produced an incremental depression in weight gain. The intestines of chicks fed this extract contained large quantities of gas that were reduced by penicillin supplementation. These results suggest that rye pectic substances may be responsible for the growth depression of chicks fed rye.
