Nutritive Value of Corn Dried at 140°, 180° and 220° Fahrenheit for Swine of Different Ages

Illinois Agricultural Experiment Station, Urbana

Abstract

Four experiments involving 48 two-week-old pigs and 48 growing-finishing pigs were conducted to study the effect of drying air temperatures upon nutritive value of corn. Drying temperatures and times with an on-the-farm portable batch drier of 375-bushel capacity were, respectively, 140° F., 2 hours, 30 minutes; 180° F., 1 hour, 27 minutes; 220° F., 55 minutes. Average corn moisture before and after drying was 21.5% and 12.2%, respectively.

Average gain and feed efficiency on the different corns were very similar within each experiment. In a 5-week palatability test 50-pound pigs showed a very slight preference for 220° F. shelled corn. When corns were roller-ground, the choice was definitely and consistently for the 140° F. corn.

Viability tests, used to measure possible milling quality, showed decreasing viability with increasing temperature above 140° F. Increased temperature did not appear to affect the organic solubles portion but the starch became slightly less susceptible to malt amylase digestion.

Vitamin assays showed no effect of temperature on content of riboflavin, niacin and carotene. However, pantothenic acid values for 140° F., 180° F. and 220° F. were, respectively, 2.58, 2.40 and 2.31 mg. per pound.
