DR. RENE SUMAOANG: He turns corn cobs into nutritious livestock feed!

Dr. Rene Sumaoang, microbiologist, ferments powdered corn cobs into nutritious livestock feed.

CORN COBS are usually thrown away at big corn processing plants and are often considered a waste disposal problem. At best, some use the cobs as fuel, others for growing mushroom.

NUTRITIOUS ANIMAL FEED – But one microbiologist, however, has found a way of converting corn cobs into nutritious animal feed. He is Dr. Ronaldo Sumaoang of Novatech, most popularly known as the maker of Durabloom fertilizers.

2,000 TONS – In a previous year, he bought 2,000 tons of corn cobs from a major corn seed company in the country. He crushes the cobs with a hammer mill so they can be made into fine powder or into coarser sizes.

FERMENTED – By fermenting the crushed corn cobs with molasses and beneficial microorganisms, the material does not only become more nutritious, it also becomes more palatable which is well-liked by livestock such as pigs, goats, cattle, carabaos and even poultry.

RICE BRAN SUBSTITUTE – Dr. Sumaoang said that the fine corn cob powder can be used feed mixes in place of the fine rice bran which is more costly. He observes, however, that the coarser materials are better-liked by the bigger animals such as sheep, goats and cattle.

FORAGE GRASS SUBSTITUTE – During the dry months when grass is not available, the crushed corn cob can be a substitute for forage grass. Dr. Sumaoang said that he no longer has a problem feeding his 300 sheep, thanks to the corn cobs he ferments.

BONUS GRAINS – Dr. Sumaoang added that at the processing plant of the seed company, not all the grains, especially at the tip, are removed during shelling. So he gets an added nutrient bonus.—ZBS Memoirs
