IMPROVEMENT OF THE NUTRITIVE VALUE OF GROUND YELLOW CORN COBS BY USED SODIUM HYDROXIDE

Abstract

Study the effect of treated the ground corncobs with 4% NaOH using two temperatures (20 and 40 C), three incubation periods (0, 15 and 30) days and three level of moisture (0, 15 and 30 days). The results indicated that the main effect of treatment have reduced significantly (P<0.05) the content of dry matter, organic matter from 968.20 and 947.10 gmkg to 724.4 and 654.06 gmkg and the content of, natural detergent fibers, hemcellulose and lignin from 841.95, 398.45 and 396.95 gmkg to 740.86, 283.05 and 336.44 as compared with untreated. A significant (P<0.05) increase in quantity of the ammonia nitrogen, acid detergent fibers acidic and cellulose from 0.105, 443.50 and 46.60 gmkg to 1.08, 456.26 and 100.07 gmkg. Also increased significantly (P<0.01) in vitro dry matter organic matter digestibility from 34.05 and 40.04% to 50.21 and 58.32% and pH from 5.83 to 9. The best treatment which gave better improvement was a associated with 30% moisture and 30 days incubation time.
