The invention relates to a Roman hen feed containing a D-ribose feed additive. The feed comprises the following main raw material components: corn, bean pulp, cooked millet, tomato seed dregs, peanut skin, sunflower seed, cooked yolk, sweet potato flour, potato powder, calcium hydrophosphate, stone powder and salt. Microelement premix, the D-ribose feed additive and a traditional Chinese medicine additive are further added in the main raw materials. The D-ribose additive comprises D-ribose, bran, corncob powder, medical stone and high-calcium stone powder. The traditional Chinese medicine additive contains schisandra chinensis, medicated leaven, Scutellaria baicalensis, folium isatidis, houttuynia cordata, salvia root, Chinese angelica, fingered citron, wild buckwheat, white paeony root and malt. By adjusting the main feed recipe and adding the D-ribose feed additive, the premix microelement and the traditional Chinese medicine additive in the main feed, the microbial flora balance in an animal body is improved, and the proliferative activity of intestinal bifidobacterium is promoted selectively, so that the daily gain and the propagation performance of Roman hens are improved.
